The invention relates to a brake system in an at least partially autonomous vehicle, comprising a wheel brake (1) for each wheel (VR, VL, HR, HL), with which a primary brake control system (BRS1) and a redundant secondary brake control system (BRS2) are associated, the main brake control system has a main controller and an electromechanical main actuator for each wheel for actuating a wheel brake, based on a desired deceleration predetermined value generated in the pilot system and/or a desired deceleration predetermined value generated on the driver side by means of the brake pedal, the main controller generates a main control signal for actuating the corresponding electromechanical main actuator. According to the invention, the secondary brake control system has a secondary controller, which is independent of the primary controller, and an electromechanical secondary actuator, which is independent of the primary actuator, for each wheel. The secondary controller generates a secondary control signal for actuating the corresponding electromechanical secondary actuator on the basis of a theoretical deceleration predetermined value generated in the pilot system.
本发明涉及一种在至少部分自主的车辆中的制动系统,该制动系统针对每个车轮(VR、VL、HR、HL)具有车轮制动器(1),为车轮制动器配备有主制动调节系统(BRS1)和冗余的副制动调节系统(BRS2),主制动调节系统具有主控制器并且针对每个车轮具有机电式主执行器以用于操纵车轮制动器,基于在先导系统中生成的理论减速预定值和/或借助制动踏板在驾驶员侧生成的理论减速预定值,主控制器产生主调节信号以用于操控相应的机电式主执行器。根据本发明,副制动调节系统具有独立于主控制器的副控制器以及针对每个车轮具有独立于主执行器的机电式副执行器。副控制器基于在先导系统中生成的理论减速预定值产生副调节信号以用于操控相应的机电式副执行器。
