Power distribution solutions towards more efficiency

CESA 2012 abstract

The well established 12V automotive power distribution system is facing some major changes. The main drivers for these changes are better energy efficiency and CO2-reduction. 12V Start-stop and 48V Mild-Hybrid solutions are seen as enablers for better efficiency.
With the innovative 12V start-stop functions, there are two new upcoming challenges to be solved, powernet stabilization and increased activation cycles.
The presentation will show semiconductor solutions for powernet stabilization, like dual battery switches, as well as solutions for replacing mechanical relays. Special interest is here also given to electronic fuse function, weight reduction by improved wire harness and a more flexible power distribution partitioning, as well as a reduction of electric power losses.
Finally the presentation will cover the 48V powernet requirements for semiconductors in Mild-Hybrid systems. Different system architectures will be discussed with their specific application needs and first 48V semiconductor families like MOSFETs, driver ICs, Voltage regulators and transceiver devices will be proposed.

Trends and Innovations in Safety Domain Architecture

CESA 2012 abstract

Since years the demand for Driver Assistant Systems is continuously growing. Forward looking camera and radar applications are gaining popularity. Not only in the luxury car segment, but also in mid end car segments and migrating further into low end cars. In addition the merge of active and passive safety applications towards cognitive safety is progressing rapidly, supported by upcoming changes in the safety rating of cars. Additional radar and camera sensors are going to be equipped around the car for side and rear looking applications migrating towards 360 degree environmental sensing. Taking advanced development programs at vehicle manufacturer into consideration first semi autonomous driving applications can be expected within this decade.
All these trends will lead to a change in the safety electronic architecture.

More and more sensor data need to be processed, data fusion has to be done on a much higher level and software functions to align and arbitrate chassis actuators need to be integrated. Furthermore, vehicle manufacturer have identified DAS function software as an important vehicle brand related selling point and started to develop this SW on their own, which has to be integrated by tier 1 supplier as black box or gray box SW.
Beside these new electronic systems, which are entering the car, we will see a lot of new technologies enabling the way towards cognitive safety. Safety systems are going to have open, Autosar based SW architectures according to ISO26262, need to support various network communications like CAN, FlexRay and in the next step Ethernet and have to provide very flexible and scalable micro processor architecture.
While flexibility and scalability do have in general an impact on the cost of the electronic systems - standard safety systems with high fitment rates are meanwhile much cost driven - a simple integration of the above mentioned functions and technologies would lead to a not acceptable cost burden in standard systems. Safety domain controller which acts as flexible, open integration hubs being additionally equipped to the car as optional electronic systems, hosting DAS or vehicle dynamic functions are ideal solutions to follow the rapidly changing market as long as above mentioned market requirements are linked to fitment rates below 30-40%. With such a controller the functions can be integrated and added very easily by allowing the standard electronic systems to stay cost optimized. TRW has developed a safety domain controller which enables the integration of a number of chassis, safety and DAS control functions. Using open, ISO262626 compliant Autosar architecture, the Saftey Domain ECU (SDE) has the flexibility to include software from vehicle manufacturers and third party suppliers and its first generation is scheduled for launch in 2013.
For its second generation SDE, TRW is exploring the application and benefits of Ethernet as a network technology – offering considerably higher data throughput speeds than current communication protocols.

2014 Cadillac ATS coupe—ATC?

Move over upscale German compact luxury coupes, there's a new ride in town.

It's just a matter of time before Cadillac's newest star, the ATS sedan is given a coupe sibling. My version, above, is not the all-out dramatically styled geometric paragon of haute couture as is the larger CTS coupe. This ATS coupe, or ATC most likely, is a bit more "practical" in appearance, more akin to the 3 series, A5 and C Class coupes. Gently rounded lines first seen on the sedan are gently becoming the new Art & Science norm, with proportion and stance as much a part of the brand's DNA as is the overt angularity.

Update:

One of the great commenters over at CarSpyShots.com's Photoshop section, where I have been posting my car chops for years, suggested I increase the glass area of the coupe a bit. Since I had raised the beltline from the donor sedan, I lowered it back to production height to see how it looked. I'm torn. I always like my original intention, but I have no problems at all with the increased glass. I think it looks quite fetching, actually!

The Second Coming of Saab

Saab PhoeniX Concept Car

People love a good comeback story, the kind where a person overcomes seemingly impossible obstacles, and Saab right now might be shaping up to be that kind of a story. Many people decided the brand was deader than dead three years ago when talk of bankruptcy and winding down the brand  was first brought up by General Motors management. After languishing for a while, the Swedish automotive brand finally seemed to succumb to the many factors that caused its demise. Many kind eulogies were written for the brand and then everyone seemed to move on.



But like a phoenix, (or maybe a zombie, depending on how things turn out) Saab refused to stay dead for very long. Now it promises to rise from the ashes of the company so many wept over, hopefully stronger and ready to thrive in the modern automotive world.

Saab PhoeniX Concept

At first, plans were to relaunch the brand with only EVs (electric vehicles). That plan was an ambitious one, one that seems to have been placed on hold. Rather than let consumers continue to think that the Saab brand is dead, the company will release a new generation of the iconic 9-3 sports sedan, but it will be gasoline-powered like in the past. Rumor has it that this new 9-3 will be based on the architecture of Saab's PhoeniX concept (but sadly the scissor doors probably won't make the cut--pun intended). In the next few years, expect to see electric Saab models rolling down a road near you.

How is it that Saab has been brought back from death? Despite what most people think, when a company goes bankrupt and closes that doesn't mean the products are dead forever. If that were the case, Jeep would have been history a long time ago. The Swedish company National Electric Vehicle Sweden AB (or NEVS) is partially responsible for this reboot. The company is owned by National Modern Energy Holdings, which is based in Hong Kong. A significant portion of the company is also owned by some private Japanese citizens, with the alliance surviving the current tension between the governments of China and Japan.

Saab PhoeniX Concept

China has been weighing in on electric car technology with a mandate for quite a few electric cars on the country's roads in the near future. This has helped fuel an interest in bringing more EVs to China. The US so far is the largest EV market in the world, so expect to see quite a few of these EV Saabs coming to America in the near future as well. I would imagine a fair amount of the new 9-3s will be landing on American shores as well, considering the US was a vital market for Saab back in the day. Still, with NEVS being based in China, and with the country's growing appetite for cars, Saab should be expecting to see a huge upswing in growth in China (just like Jaguar, Land Rover and Volvo are all experiencing).

Of course, everything is up in the air right now. Relaunching a car brand is not an overnight process, especially with part supply chains, readying factories, negotiating with assembly workers, training, testing, etc. I'm sure the public's response to this news will play a factor in deciding if Saab is back next year, so let's all make sure to let NEVS know there's still a viable market for a combustion engine 9-3!

Developing embedded user experiences - challenges and success factors in automotive environment.

CESA 2012 abstract

Automotive product development is based on proven processes and development time that allows carmakers to respond to drivers needs in regards to quality, feature availability and look and feel of the device in the car.
When talking about user experience, driver’s expectations are influenced by consumer electronic devices, from interaction point of view (speech and/or gesture recognition) as well as content (graphic attractiveness, apps). Drivers are expecting the same seamless, simple, easy to use phone and tablet features in their car, while still requiring automotive quality in term of system stability, low driver distraction and updateability during automotive life-time.
With over a decade of experience in developing multimodal HMI, EB GUIDE – industry recognized HMI development products suite and speech dialog platform - has been proved reliable in more than a million vehicles on the road and in the upcoming year more vehicles will come to market using the EB GUIDE HMI technology.
During the presentation, you will learn about market trends in HMI, the market interest for a modelbased approach, quick UI simulation for user-acceptance evaluation, how to easily enable early and agile development, as well as integrating latest technologies to handle gesture/speech recognition and graphics challenges into the vehicle.

The Joys of Driving a Minivan!

I am a car guy, but I'm also practical and I'm not rich. I also have several kids (which is partially why I'm not rich) to transport safely and comfortably around town and on long trips. Because of my life situation I have found myself doing what I swore I would never, ever do: I bought a minivan.



What's so bad about owning a minivan? Many people consider minivans to be a scourge on the road. I've noticed the most violent reactions against minivans and those who drive them come from women. Perhaps these women view minivans as an undue form of female bondage, like the bra-burning flower children of the 1960s? I once had a woman explain to me that driving a minivan is "sacrificing your sexuality for your children." I had no idea I drove my sexuality around on the road, but of course the little guys who drive huge trucks help confirm that at least some people do. How sad.

I really like SUVs for a number of reasons: they are excellent in snow, SUVs are good for camping and other outdoor activities and some can actually be fun to drive (while others constantly feel like they're going to tip over). But there is one major problem with 95% of the SUVs on the market today: if they have a third row, its large enough to transport a house cat or maybe a beagle and that's about it. Don't believe me? Go try to sit in the third row of a Toyota Highlander, Volvo XC90, Acura MDX or even a Ford Explorer. If you're tall like me, you won't even fit. To add insult to injury, with the third row up the vehicle's cargo area is completely annihilated. So that means if the family goes shopping together, everyone has to hold the store bags on their laps. Road trips are accomplished with everyone holding the luggage or using it as wonderful in-vehicle ottomans, or by loading everything onto the roof and increasing the possibility the vehicle will rollover at freeway speeds. Car makers could at least expand the hip room on the second row of these SUVs, allowing parents to place three car seats or boosters side-by-side and still close the doors and use the three shoulder belts.  

Minivans in general offer more cargo and passenger space than SUVs

Minivans, for the most part, have ample space on all three rows, as well as a surprising amount of cargo space behind the third row. Image be damned, having space for everyone and everything makes life bearable! Kids also have an easy time getting into and out of minivans, since they have a low step-in height and wide sliding doors. Kids have trouble with the large, heavy doors found on SUVs, which means they're more likely to hit other vehicles, metal poles, etc with them.

As gas prices continue to climb, minivans offer a more fuel-efficient way to transport a large group of people. In general, their tires and other consumables cost less. They are a more budget-friendly way to transport around your family. So many people have SUVs that cost an arm and a leg to maintain, and yet they never tap into the vehicle's off-road capabilities. If that's not conspicuous consumption, then I'm not sure what is. 

Ultimately I feel like I'm villainized by other drivers on the road because I chose a vehicle that makes sense. I had been conditioned to think that minivan drivers were some sort of a scourge, but my thinking has now changed by necessity. If more people would give minivans a try, they might realize that their kids don't need to eat their knees in an SUV's crammed third row. My experience is that the more comfortable kids are in a vehicle, in general the better behaved they are in that vehicle. I enjoy driving down the road without crying and fighting, which is hardly a scourge but instead is a huge blessing.

The Robot Cars Are Invading!

 
I grew up watching the Transformers (as well as the hopelessly inferior GoBots) and so from an early age I have a positive association with robot cars. Night Rider was also part of my ultra-healthy diet of mindless television, which also helped prepare me for the future of automobiles.

Yes, that's right folks, the future of automobiles will be robot cars. Like it or not, states like California are helping usher in a new era in motoring (as my friends across the pond like to say) where the human behind the wheel is not the only one driving the car. 



What baffles me is the massive opposition to robot cars. There are throngs of people who are upset, saying robot cars are dangerous (these people watched the Terminator and the Matrix a little too much), that they take away our freedoms and that robot cars will create the ever-dread "nanny state" I keep hearing about. If you don't believe that robot cars are a hot-button issue, check out this real (I swear it is real) political ad from Florida:

 
Back in the day windshields were called "not commercially viable" by people who irrationally were fighting any kind of change. Considering how many deaths and serious injuries are caused by car accidents, and how many people who want to do everything but drive when they're behind the wheel, I think the benefits of autonomous cars are immense. How many times have you been in a near car accident that was due to another person talking or texting on their phone, or doing something else that completely distracted them? A robot car would prevent the damage to property and loss of life that comes from car accidents (which are altogether too common). In fact, according to the United States CDC, the number one killer of teens in the US is car accidents! 

Of course, not all autonomous car tech is created equal, so the debate should really be about what is the best way of going about it.Having a system where all the cars are controlled by a central group of servers can be a recipe for disaster, since one glitch could cause thousands of cars to drive out of control, leading to catastrophic car accidents. Instead, tech like Google's self driving cars is far better, since a glitch would only affect one or just some of the cars on the road. 

To those who bristle at the thought of a computer driving a car, since computers won't be as careful, consider that humans have proven to be quite careless behind the wheel. Most of these robot cars will allow drivers to take control at any time, so in the event of a malfunction the human driver can still maintain control. This could also mean that people could drive without using the robot aids, just like how you can turn the traction control system off on your car (and let your tires spin uselessly as a result). The point is people would have the robotic aids, just like how people have backup cameras and other technology that makes driving a car a safer and easier experience.

2014 Cadillac Seville: The New Standard of the World

This is a rendering for a 2014 Cadillac Seville, a longer-than-XTS, rear-wheel drive, twin-turbo hybrid flagship with all mod-con electronic geegaws and doodads.

Starting with the XTS donor image, I replaced the original fastback 6-window greenhouse for a more tradition 3-box sedan. The new C-pillars are nicely faceted and lead to a roofline nodding back to the '75 X-body Seville. I lengthened the hood and pulled the front wheels forward for the new V8 drivetrain. The wheelbase is 10 inches longer than the front-wheel drive XTS with an extended rear passenger compartment as well. The extended range battery pack is nestled in the platform's raised center spine for handling and packaging needs, making this the first top-of-the-line Cadillac sedan to offer four Nappa leather-covered electronic Recaro bucket seats.

The thermal management of electrified vehicles

CESA abstract

When running on pure electric mode, electrified vehicles offer a very efficient energy conversion. Less than 3 kW in average is needed to drive an EV over an urban cruise. Consequently, the management of additional power demands of thermal functions, e.g. the cooling or the heating of the vehicle passenger cabin, or that of battery and power electronics, has a major impact on the overall vehicle power balance. A new system approach for thermal management, combining an innovative architecture, dedicated technologies and relevant control strategy, becomes decisive to offer a significant cruising range, secure the battery life time and also ensure quick engine response.
Within the scope of Vega/Thop, a cooperative project including six partners (Valeo, Renault, Saint Gobain Sekurit, Hutchinson, INSA/Cethil, LINC) funded by Ademe, a new thermal architecture was designed, prototyped and tested on benches and lab cars in order to assess the potential of such innovative thermal concept.

This paper outlines the main challenges and the outputs of this project:
- the review of thermal needs, with a focus on the passenger cabin requirements for comfort, and their associated impact on vehicle performances at system level;
- the way to drastically reduce the cabin thermal needs with same perceived comfort, combining cabin treatment, advanced air management and alternative comfort strategy;
- the setting up of a new thermal architecture that combines heat networking, recovery and storage capabilities, looking for synergies between thermal needs and heat losses so as to minimize consumption.
- the implementation of a heat pump to leverage “free” low temperature heat sources, such as ambient air or internal heat inertia and losses
- the benefit of a transient control strategy, in order to manage different operating modes and related “ramp up” or cycling phases, according to the vehicle usage profile.
As a conclusion, typical power savings compared to current serial EV will be presented on different scenarii, based on the results from tests campaigns and simulations analyses.

Are You What You Drive?

2013 Land Rover Range Rover

The old Detroit adage was "you are what you drive." Actually much of the automotive industry, not just American automakers, have drummed this into people's heads for decades. I have heard people use this phrase with glee (when they have a car they just love) as well as with disdain (when they have a car they would love to drive off a cliff). Is it really true?



There are many stereotypes revolving around people who drive different types of vehicles. I have owned a variety of vehicles, and always notice with a little twist of humor that people treat me differently depending on the car I drive. For example, when I had my little Volvo S40 (which for those of you who don't know is a compact Swedish sedan) I would regularly get cut off by the "big truck crowd" or guys driving full-size pickups. I even had one cut me off on the freeway, slam on his breaks and then gun it so a cloud of diesel exhaust spewed all over my car as he waved a finger out his window. After my car was in a little fender bender and then had to take a trip to the body shop, I was given a rental full-size pickup truck to drive around. I immediately noticed the other full-size pickups on the road treated me like royalty, but a new group started to target me: middle-aged women in economy cars! I kid you not, I would have women in Civics, Mazda Proteges, Corollas, etc ride up so close behind the truck I could barely see the roof of the car in my rearview mirror, meanwhile in my side mirror I could see them yelling and making faces at the back of the truck. What I couldn't believe was that if I had slammed on the breaks, these women would have been pulverized by a vehicle that weighed at least twice as much as theirs.

When I drove a Japanese SUV I had people in American SUVs try to show off all the time, and while driving my Saab I would have BMWs try to race me and Lexus drivers cut me off constantly. Driving a minivan now, I have the lovely joy of women (yes, pretty much just women and not men) treating me like I am the scourge of the earth and shouldn't be allowed on the roads. I could go on, but I think you get the point.I think it's pretty safe to say quite a few people have bought into the belief that the vehicle makes the person.

Does owning a Ford Raptor make you a more active person?

I would argue that a vehicle doesn't transform who you are. To an extent the vehicle does affect how you drive: I don't go nearly as fast in my current vehicle as I did in my Saab, and when I had an SUV I wouldn't hesitate to plow through deep water on the road. I would argue, though, that the person chooses the vehicle, and that different people gravitate to specific vehicles for a number of reasons. It's not always cut-and-dry like some try to pretend, but I do think that the type of vehicle you drive says a lot about you and the stage of life you're in.

Automotive industry marketers would agree with me. I often see automakers' profiles for buyers of different vehicle models. For example, once I saw Honda's for Accord drivers. I don't remember everything about the profile, but I do remember that they found the average Accord driver vacuums out his garage rather than sweeping it. While you can't say that everyone who drives X vehicle is exactly the same, you can say that most people who drive the same vehicle share some key traits. I do believe the list of similarities between drivers with the same vehicle grows tighter the more "niche" the vehicle is in the marketplace. For this reason, I think this is why there is such a strong Subaru culture or a similar group of people who drive Mazda Miatas. Meanwhile, you will find a less homogenous group of Camry drivers, although most Camry drivers do share some key traits (just not as many as Subaru Forrester drivers). 

I could also launch into a big, deep discussion about vehicle customization and what it says about people. I wrote up a 60+ page paper (complete with photos) for a college class on this very subject, and trust me I could write a 500+ page book on it. But we'll leave it for another day, and maybe even for a future book. 

Perhaps we should modify what we say about a car being an extension of a person. I guess we could always say "what you drive reflects who you are" but that just wouldn't be very catchy.

Individual E-Mobility Solutions for Automotive and Off-Highway Applications – A System View by Bosch

CESA 2012 abstract

Only a couple of years ago there were many doubts on a possible implementation and realization of hybrid and electric vehicles as an alternative for vehicles with an ICE powertrain.
Today we are in the position to see this differently. “The future automotive powertrain will be electric” is a prognosis of Bosch. The conversion of the powertrain to be electric assisted or become all electric was pushed through significant development effort over the last couple of years.
Today we see the hybrid technology being used in many different platforms of almost any OEM and the first all electric vehicles are available from series production. But the electric powertrain is not only revolutionizing the automotive industry.
At Bosch Engineering we are getting more and more requests for hybrid and electric powertrain solutions for off-highway applications. This includes for example fork lift trucks, municipal multi-purpose carriers, and also marine applications. These applications could benefit from the system and sub-system development efforts for automotive solutions and from the mature and high quality of powertrain components.

For any application it is important to make sure, that the requirements and the duty cycle are well understood and that the system, sub-system and the components are very well fitted together for their individual usage. High efficiency plays an important role, especially for the electric powertrain, since energy storage systems are still very cost effective. High performance simulation tools are used to support the effort of finding an overall optimized solution. Safe and environmental friendly solutions are a must for Bosch. However cost, efficiency, function, weight and packaging are also important requirements. Often, the first system development solution found is not the best to meet all these criteria. Iterations have to be made using simulation tools and measurements in order to find out what is best for each individual system layout.
What has to be kept in mind: “The optimum of each subsystem and component is not necessarily the overall optimum of the entire system“.
