Brake System for a Motor Vehicle and Method for Controlling said Brake System |
| 摘要 |
A brake assembly includes a hydraulic auxiliary-power-operated first brake system including a master brake cylinder operably connected to an electromechanical brake booster and a hydraulic wheel brake for at least one wheel, the master brake cylinder configured to be activated by muscle force, and an externally powered second brake system including a hydraulic pressure source operated by external power and operably connected to a hydraulic wheel brake for at least one other wheel. The brake assembly further includes an electric drive motor configured for operation as a generator to brake the motor vehicle by acting on the at least one other wheel and a control unit configured to reduce a braking effect of the first brake system by reducing boosting of the electromechanical brake booster, if a braking effect of the electric drive motor in a generator mode is greater than the determined braking effect of the second brake system. |

1. A brake assembly for a motor vehicle, comprising:
a hydraulic auxiliary-power-operated first brake system including a master brake cylinder operably connected to an electromechanical brake booster and a hydraulic wheel brake for at least one wheel, the master brake cylinder configured to be activated by muscle force; an externally powered second brake system including a hydraulic pressure source operated by external power and operably connected to a hydraulic wheel brake for at least one other wheel; an electric drive motor configured for operation as a generator to brake the motor vehicle by acting on the at least one other wheel; and a control unit configured (i) to determine a braking effect of the second brake system for a current position of a brake pedal, and (ii) to reduce a braking effect of the first brake system by reducing boosting of the electromechanical brake booster, if a braking effect of the electric drive motor in a generator mode is greater than the determined braking effect of the second brake system. |
