Abstract (en)

[origin: WO2015051929A1] The invention relates to a method for operating a brake system of a vehicle which comprises a master brake cylinder (4) which can be activated by the driver by means of a brake pedal (1), at least one driver-independent pressure source (11), at least one wheel brake (9a, 9b) to which a wheel speed sensor is assigned, and a brake activation sensor (5), 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 (11) is activated. According to the invention, a hazardous situation is detected when the change in a measured deceleration (a) over time or the absolute value of a measured deceleration (a) exceeds a predefined hazard threshold value (active) 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 ("brake assistant") which does not require a master brake cylinder pressure sensor.
