SUMMARY

"A system for situations non manageable by braking only"

The most dangerous situations in traffic will appear when the weather conditions on the road are changing unexpectedly and substantially.

Especially in the winter the friction may vary dramatically just in few minutes or within a few hundred meters. Black ice is very dangerous and often you will not know of its existence until you hit it.

A problematic situation may evolve even from a routine like braking, where the less than expected deceleration surprises the driver and uncertainty related to the function of the brakes leads the driver to react the wrong way.

Without any feedback about deceleration the driver tries to force the vehicle to stop using more and more power on the brake pedal, which creates physical difficulty to steering and the possibly needed steering actions to avoid the crash can be completely missed. One might be hesitant, and don't apply enough pressure with the result that the hydraulic brake-assist system is not triggered. The driver may even give up when feeling unable to influence the course of events.

To avoid the problems it is necessary to provide the driver with the information that the maximum deceleration has been reached and one should concentrate on steering.

Anyone who has completed driver safety training knows, that it is often a better choice to control the car by evasion and braking rather than braking alone.

Actually today in many cases drivers desperately wish to have this kind of "aid".
