My data on systems is getting stale but the major system is an enhanced ABS
with Stability Control as added functionality. So, Bosch, Continental Teves and
GM all had their own systems. That was most of the market through 2005, but
then TRW and Akebono were late to the market. Bosch made the first systems
for MB using their own gyro and CT/GM used a gyro from BEI, now Schneider Elec.
Several other Gyro makers have entered the fray in the past couple years. The
gyro is what measures yaw (about to spin) but then it is the computer program from
each car mfg that tells the system what to do from that point. Toyota had some
really terrible systems early on while MB, Porsche, BMW and Corvette had some
of the best. Oh, the system usually also uses data from wheel speed sensors to
get wheel slip info as well. Some of the systems use Accelerometers to get linear
data too, it all adds up to how drivable the system is and how noticable it is, which
it shouldn't be. All those component mfg'rs have been doing well since 2000.

If you think a few years of ESC sales will be a major impact, think of the numbers.
With about 250M cars on the road in the US and sales of say 15M and less than
50% having ESC, the impact is going to be small until several years after the
requirement is on 100% of new sales. The saved lives figures were based on 100%
of the fleet having the system, which may get close about 2020 or later.

This video makes it look like Toyota's stability control still isn't as good as others.
It still keeps it from completely spinning out of control, but looks much more precarious.

Here is a very good extended video of stability control on a Jaguar X-Type.

The Jaguar did better at high speed on ice than the Tundra did at much lower speed on wet asphalt.

"The Jaguar did better at high speed on ice than the Tundra did at much lower speed on wet asphalt."
 
The pickup truck test looked like it may have been done on a synthetic ice surface (enables icy road testing in milder climates). Even so, both of the pickups slid around quite a bit!

Well, almost a year later and hardly any posts. ESC is still under the radar.

Recent info on the migration to the system and studies on impact. 2012 MY
vehicles are still 2 1/2 years away. Interestingly they do mention that the
systems are different and that is expected since, as noted, Corvette drivers
want more leeway than other drivers . Just glad I've had it for 8 years now.

Interesting news out of Australia:

Wonder how long it will take to get similar item in US?
 
Well since they have figured out how to retrofit truck trailers,
I would guess that someone will figure it out for the auto market:

For anyone interested in the Mems market:
A few mentions of Yaw sensors,

Interesting stuff, especially the first article with the gizmo that's intended for "race track" use only, and your insurance company isn't going to like you being able to change the stability control parameters.
 
Chips are becoming pervasive in car systems eh?

You know I believe I am getting close to ready to see them put a programing feature into our vehicles like an auto pilot. With the Volvo demonstrations on TV news showing a car that will stop itself if the driver isn't paying attention it seems as if we getting ready for the transportation pods. I didn't like ABS when it came out because I had learned to drive without it. Now I don't even notice unless I happen to be on a slick wet road and my tires slip on the painted white line. I don't think skid control will be noticeable to 99 percent of the drivers. It might be when it comes to the price of the vehicle but not because the driver notices anything. we have become used to power windows, power brakes, power stearing, even electric stearing, some cars have used brake by wire but I haven't tried it. I have seen a HUD and I was slightly impressed. I can get a radio I can talk to and it plays what I want it to. Maybe I am getting ready for a computer car.
