METHOD FOR OPERATING A BRAKING SYSTEM AND A BRAKING SYSTEM

摘要

A method for operating a brake system of a vehicle which includes a master brake cylinder which can be activated by the driver by a brake pedal, at least one driver-independent pressure source, at least one wheel brake to which a wheel speed sensor is assigned, and a brake activation sensor, wherein it is checked whether a hazardous situation is present, and in the case of a hazardous situation being detected the at least one driver-independent pressure source is activated. A hazardous situation is detected when the change in a measured deceleration over time or the absolute value of a measured deceleration exceeds a predefined hazard threshold value and a brake activation operation is detected. In addition, the invention relates to a brake system for a motor vehicle having brake assistance in hazardous situations which does not require a master brake cylinder pressure sensor.

1. A method for operating a braking system of a vehicle, said braking system comprising a master brake cylinder that can be actuated by the driver by a brake pedal, at least one driver-independent pressure source, at least one wheel brake that is allocated a wheel rotational speed sensor, and a brake actuation sensor, wherein a check is performed as to whether a dangerous situation is present and, in the event that a dangerous situation is detected, the at least one driver-independent pressure source is activated, wherein a dangerous situation is detected if a gradient with respect to time or a value of a measured deceleration exceeds a predetermined danger threshold value and a brake actuation is measured.
