The invention relates to an intelligent vehicle pump and steering motor heterogeneous redundant steering system and a control method thereof. The steering system comprises a main driving module of a variable-speed pump-driven double-steering power-assisted cylinder, an electronic control module, a control redundancy module, a manpower and unmanned steering redundancy module, a high-pressure source redundancy module, a pipeline redundancy module, a steering mode redundancy module, an overload protection module, a corner precise control module and an unmanned steering redundancy module. According to the steering system, unmanned switching among different steering modes is achieved through the redundant synergistic effect of a plurality of modules so as to deal with hydraulic assembly faults and different driving modes, it is guaranteed that the steering system has the redundant safety function, and the reliability and safety of a vehicle are improved. The system can be switched to the standby system when the main system breaks down, it is ensured that the vehicle continues to keep controllability, the emergency capacity and fault tolerance are enhanced, and accidents caused by single-point faults are avoided.
本发明涉及一种智能车辆泵与转向电机异构冗余转向系统及其控制方法,该转向系统包括变转速泵驱双转向助力缸的主驱动模块、电子控制模块、控制冗余模块、人力与无人转向冗余模块、高压源冗余模块、管道冗余模块、转向模式冗余模块、过载保护模块、转角精准控制模块和无人转向冗余模块。该转向系统通过多个模块冗余的协同作用,实现了不同转向模式间的无人切换,以应对液压组件故障和驾驶模式的不同情况,保证转向系统具有冗余安全功能,提高车辆的可靠性和安全性。它能够在主系统发生故障时无人切换至备用系统,确保车辆继续保持可控性,增强了应急能力和容错性,避免因单点故障导致的事故。
