The 2009 Flex will be available with the Ford Collision Warning System

System warns of impending collision and prepares brakes

Ford Motor Company is betting big on new technology to help drivers avoid accidents. Most cars on the road today utilize technology like air bags to help you survive an accident, but typically only expensive luxury cars utilized technology that actually helped drivers avoid a crash.

Ford announced a new technology called Collision Warning with Brake Support that is coming in 2009 on certain Ford and Lincoln vehicles. The crux of the system is that it detects an imminent collision via a type of radar and produces a tone over the cars audio system to warn the driver.

In addition to the tone warning, the system also projects a red warning light onto the windshield of the vehicle. At the same time the audio and visual warnings are going off, the system primes the brakes for emergency stop.

Braking is pre-charged and a brake-assist feature is engaged to help the driver get maximum braking force as soon as possible. Paul Mascarenas, Ford VP of product engineering, Global Product Development said in a statement, "The new Collision Warning with Brake Support technology puts us on the leading edge of active safety to help customers detect and avoid possible dangers. Ford will be the first to offer this technology on mainstream models that many families can afford."

Ford is mum on exactly what the Brake Support system entails and how specifically it works. It doesn't appear that the system starts braking the vehicle alone; the driver has to initiate braking. Collision warning with Brake Support isn’t the only radar assisted safety system making its way into Ford and Lincoln vehicles.

Ford is introducing Adaptive Cruise Control that will adjust the speed of the vehicle when cruise is engaged depending on proximity to other vehicles. Ford has also announced a system known as BLIS (Blind Spot Information System) that also uses radar.

DailyTech reported this week that Ford introduced a speed limiting key system called MyKey that limits the car to lower speeds when used to start the vehicle. The system is being marketed to parents of teenage children. Interestingly, Bugatti uses a similar system on its exotic Veyron; a special key is needed to get maximum speed from the car.

Ok , brain surgeon, explain the mechanics of why ABS increases the stopping distance!
By inference , you are saying you know how to lock your brakes in the wet and still stop quicker than ABS!
Join FIT in the back of the classroom, please.

ABS excels at " panic breaking ". In other words, breaking that would otherwise cause a 4 wheel lockup. But for all other transitional breaking, yes, anti lock will slightly increase your stopping distance. So technically hes right, and wrong.

For extreme weather conditions obviously ABS is superior as even one wheel locking up in ice/snow/rain can cause unwanted lateral rotation.

ABS, by allowing the blocked wheels to not brake until they start turning again, increase braking distance in "perfect conditions" (dry asphalt, when the locked wheels and the rolling ones have about the same traction).
ABS is useful only when you try to manoeuver while braking (which with ABS you can no matter how hard you push on the brake pedal), or when you want to stop but the locked wheels have less traction than the rolling ones (on water films, snow, and so on).
Look at braking distance with and without ABS on dry asphalt - from 60 to 0, for one model of car it was 42 with ABS and 40 without it.

Like I said , boys, go to the back of the class.
What kind of education allows you to open your mouths on something you don't understand?
Best braking is done when you have the most friction between rubber and road. This is at its maximum JUST BEFORE LOCKUP. At 5-10 times a second, ABS works so much faster than a dickhead driver, at keeping the friction at its optimum point. If you are getting "without" figures to be better, then ABS hasn't been implemented very well on that car. In which case I would never ever buy that car!!!!

Ditto this. I don't know how to rate your post up, but you're spot on. A tire loses a lot of its ability to slow the car when you drive it into too much slip; that is, when the rotational speed of the tire differs too much from what it would be if it was rolling freely.

How do I know ? I'm an ABS development engineer for a major automaker.

Here's the bonus for the remaining unabombers out there-ABS will increase stopping distance on deep, soft surfaces, that's deep, soft (I said DEEP & SOFT, not around town at noon) snow and loose gravel where the wedge in front of a locked tire will help stop better than the tire can grip the surface. In these conditions, ABS still allows steering where locked tires don't.

When ABS first became available , issues about its effectiveness in gravel came to the for. These issues have now been resolved with subtle ABS tuning. Basic science. I guess I payed attention in class, lol.
I repeat for the ignoratus out there, if you dont understand, don't create "white noise".
