PROCESS FOR OPERATING AN ACTUATION UNIT FOR A MOTOR VEHICLE BRAKING SYSTEM |
摘要 |
A process is disclosed for operating a brake actuation unit of a motor vehicle braking system of the brake-by-wire type comprising (a) a brake booster which can be actuated by a brake pedal and by an electronic control unit according to the driver's wishes, means being provided for breaking a force-transmitting connection between the brake pedal and the brake booster in the brake-by-wire operating mode; (b) a main brake cylinder connected after the brake booster; (c) means for sensing a driver's deceleration wishes, and (d) a pedal path simulator which interacts with the brake pedal for simulating a restoring force acting upon the brake pedal independently of the actuation of the brake booster in the brake-by-wire operating mode and which can be switched on in the brake-by-wire operating mode when the force-transmitting connection between the brake pedal and the brake booster is broken and switched off when not in the brake-by-wire operating mode. In order to minimise a fixed structural gap a between the end of a piston rod (10) coupled to the brake pedal (1) and a control piston (11) of the control valve (9) of the brake booster (3) during regenerative braking processes, software measures are implemented while the brake pedal (1) moves through a predetermined actuation path, while the brake booster (3) remains out of operation, immediately before a force-transmitting connection is established between the brake pedal (1) and the brake booster (3), so as to prevent the force-transmitting connection from being established between the brake pedal (1) and the brake booster (3). |
