The invention discloses a brake redundancy control system and method for a drive-by-wire chassis, and relates to the technical field of intelligent drive-by-wire chassis safety. The control system collects pressure data and displacement data through a data collection unit, and detects whether a drive-by-wire brake unit, an electronic control unit, a power supply unit and/or a bus break down or not through a fault detection unit; when the electronic control unit breaks down, the backup control unit generates a second control signal, or when a certain device breaks down but the electronic control unit does not break down, the backup control unit generates a first control signal, a third control signal or a fourth control signal according to the specific broken-down device; the power supply unit distributes voltage to the steer-by-wire unit, the drive-by-wire driving unit and the brake-by-wire unit according to the first control signal, the second control signal or the fourth control signal; the backup power supply unit distributes voltage according to the third control signal; the drive-by-wire steering unit, the drive-by-wire driving unit and the drive-by-wire braking unit conduct steering, driving and braking according to the first control signal or the second control signal or the third control signal or the fourth control signal.
本发明公开一种线控底盘制动冗余控制系统及方法,涉及智能线控底盘安全技术领域,所述控制系统通过数据采集单元采集压力数据和位移数据,通过故障检测单元检测线控制动单元、电子控制单元、供电单元和/或总线是否发生故障;当电子控制单元发生故障时,备份控制单元生成第二控制信号,或当某一器件发生故障但电子控制单元未发生故障时,根据具体的故障器件生成第一、第三或第四控制信号,供电单元根据第一、或第二、或第四控制信号为线控转向单元、线控驱动单元和线控制动单元分配电压;备份电源单元根据第三控制信号分配电压;线控转向单元、线控驱动单元和线控制动单元根据所述第一、或第二、或第三、或第四控制信号进行转向、驱动和制动。
