Hydraulic Brake Assist System - HBA

The hydraulic brake assist helps the driver in the event of emergency or panic braking. The brake assist recognizes from the operating speed of the brake pedal whether the driver wants an emergency stop and increases the brake pressure automatically up to the ABS control range, as long as the driver keeps the pedal pressed.

With decreasing brake pressure actuated by the driver, the system reduces brake pressure again to the normal value. Using a sensor, the system detects the rapid pressure increase when actuating the pedal and intervenes to regulate braking. As a result, the stopping distance can be shortened by up to 25%.
