Brake assist systems are an important aid in emergency braking situations - such as when the driver applies the brake fast, but not with sufficient pressure, which leads to dangerously long braking distances. The brake assist recognizes the brake application speed to detect this type of panic situation and activates the brake booster or the EBS hydraulic unit, so that even with moderate pedal forces maximum deceleration is achieved. We offer different technologies for this purpose:

Electronic Brake Assist BA

Vacuum brake booster with electronic brake assist function and standard ABS-TMc interface. This type of active brake booster is also used to increase the response dynamics of ESC* systems (Electronic Stability Control) and to realize the comfortable electronically controlled application of the brakes for an Adaptive Cruise Control system (ACC).

Mechanical Brake Assist MBA

The MBA replaces the sensor required in the electronically controlled system to detect pedal velocity utilizing the inertial effect of an intelligent mechanism. At high pedal speeds, this mechanism triggers the BA function.

Hydraulic Brake Assist HBA

This latest solution is based on existing components in the Electronic Stability Control (ESC)*. The BA function is triggered through extension of the ESC software and requires inputs e.g. from the pressure sensor in the tandem master cylinder.
