Bosch’s new driver assistance system, ‘Predictive Brake Assist’, helps drivers in the event of an imminent accident by preparing the brake system for emergency braking. This represents the first stage of the component maker’s Predictive Safety Systems product line-up – systems with preventive effect.

While unnoticed by the driver, Predictive Brake Assist builds up preventive brake pressure by placing the braking pads on the brake disks as a matter of precaution and setting the hydraulic brake assistant into a state of ‘alert’. If the driver actually brakes, he gets the fastest possible brake response with optimal deceleration values and the shortest possible stopping distance. When there is no braking action, the alert status is simply cancelled. The system has been first installed as an additional function of the Adaptive Cruise Control (ACC) system in the new Audi A6.
In 2006, Bosch plans to launch a Predictive Safety System which gives an early warning to the driver in critical traffic situations – such as by giving a noticeable brake pulse – which will in many cases help to prevent accidents. In a further stage of upgrading, the system will additionally trigger a fully automatic emergency braking with maximum vehicle deceleration if a collision is unavoidable, thus helping to reduce the severity of the accident and its consequences.
