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

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.

I can tell you how these pre-braking systems work, they use the ABS/stability control hardware to (1) apply a slight pressure in the system to remove the pad knockback that pushes the pads away from the rotors while you drive, this allows your brake apply to produce deceleration several milliseconds faster and (2) it may enable a panic brake assist because, contrary to what you may believe, many drivers, even in a panic stop, do not apply enough brake pedal force to drive the tires to full deceleration; the ABS system detects a panic stop and increases line pressure to drive the system into max decel.
And while I can't speak for your Subaru's ABS system, a typical ABS performance requirement is for the system to outperform a driver's best distance on snow, ice, wet and dry. Drivers can't modulate all 4 tires individually when they begin to lock, so any competently tuned ABS system has a huge advantage.
