Abstract
A brake system for a motor vehicle includes an electrohydraulic partial brake system, an electromechanical partial brake system, a redundant power supply, and an actuating device (124). The actuating device is configured to determine an actuation signal quantifying a brake request as a result of an actuation by a vehicle driver. The brake system includes a brake control unit (118) with at least two mutually independent partitions. Both partitions are each configured for controlling the electromechanical partial brake system and the electrohydraulic partial brake system on the basis of an actuating signal received from the actuating device.
Claims21
1-21. (canceled)
A brake system for a motor vehicle, the brake system comprising:
- an electrohydraulic partial brake system;
- an electromechanical partial brake system;
- a redundant power supply;
- an actuating device configured to determine an actuating signal quantifying a brake request as a result of actuation by a vehicle driver;
- a brake control unit with at least two independent partitions, wherein each partition is configured to control the electromechanical partial brake system and the electrohydraulic partial brake system on the basis of an actuating signal received from the actuating device.
The brake system as set forth in claim 1, wherein the electrohydraulic partial brake system acts on a front axle of the motor vehicle and the electromechanical partial brake system acts on a rear axle of the motor vehicle.
The brake system as set forth in claim 1, wherein each independent partition comprises a closed loop control microcontroller for carrying out brake open loop control and brake closed loop control functions on the basis of an actuating signal received from the actuating device.
The brake system as set forth in claim 1, wherein the electrohydraulic partial brake system comprises an electric motor-driven pressure provision device for generating a hydraulic brake pressure in hydraulic wheel brakes assigned to the electrohydraulic partial brake system, wherein the pressure provision device may be disconnected hydraulically from the hydraulic wheel brakes by a first pressure sequence valve arranged between the pressure provision device and the wheel brakes.
