The invention relates to fault tolerant brake load mitigation. A brake system control unit includes one or more sensor interfaces configured to receive a brake torque signal from a brake torque sensor. The brake system control unit also includes a torque estimator configured to generate an estimated brake torque signal based at least in part on the brake model and the brake actuator command. The brake system control unit also includes a control circuit configured to generate a brake actuator command to actuate a brake actuator of the brake system. The brake actuator command is generated based on the brake pedal command and the load mitigation command. Depending on whether a sensor fault condition associated with the brake torque sensor is detected, a load mitigation command is generated based on the brake torque or an estimated brake torque signal.
本公开涉及容错制动载荷减轻。一种制动系统控制单元包括一个或更多个传感器接口,所述一个或更多个传感器接口被配置成从制动扭矩传感器接收制动扭矩信号。制动系统控制单元还包括扭矩估计器,该扭矩估计器被配置成至少部分地基于制动模型和制动致动器命令生成估计制动扭矩信号。制动系统控制单元还包括控制电路,该控制电路被配置成生成制动致动器命令,以致动制动系统的制动致动器。制动致动器命令是基于制动踏板命令和载荷减轻命令生成的。取决于是否检测到与制动扭矩传感器相关联的传感器故障状况,载荷减轻命令是基于制动扭矩或估计制动扭矩信号生成的。
