The invention relates to a vehicle body controller, a steering system and a vehicle. The vehicle body controller comprises a main control unit, a main driving unit, a redundancy control unit and a redundancy driving unit. The main control unit is connected with the main driving unit and the redundancy control unit and used for controlling the main driving unit to drive a steering motor to conduct steering control according to the collected turning angle signal, the torque signal, the vehicle state signal, the torque signal and the wheel speed signal. The redundancy control unit is connected with the redundancy control unit and the main control unit and used for controlling the redundancy driving unit to drive the steering motor to conduct steering control according to the collected turning angle signal, the torque signal, the vehicle state signal, the torque signal and the wheel speed signal. The driving and control part of the steering motor in a traditional steering control system is integrated into the vehicle body controller, decoupling of the steering motor and a driving and control circuit of the steering motor is achieved, the arrangement position of the steering motor has more choices, and larger assisting power can be provided.

    本发明涉及车身控制器、转向系统及车辆,车身控制器包括主控制单元、主驱动单元、冗余控制单元与冗余驱动单元;主控制单元分别与主驱动单元以及冗余控制单元连接,用于根据采集的转角信号、扭矩信号、车辆状态信号、力矩信号与轮速信号控制主驱动单元驱动转向电机进行转向控制;冗余控制单元分别与冗余控制单元以及主控制单元连接用于根据采集的转角信号、扭矩信号、车辆状态信号、力矩信号与轮速信号控制冗余驱动单元驱动转向电机进行转向控制。本发明将传统转向控制系统中转向电机的驱动及控制部分集成到车身控制器中,实现了转向电机与其驱动及控制电路的解耦,使得转向电机的布置位置具有更多的选择,可以提供更大的助力。
