The invention belongs to the technical field of drive-by-wire chassis control, and particularly relates to a multi-degree-of-freedom drive-by-wire chassis redundancy and safety control system which comprises a drive-by-wire chassis controller and a drive-by-wire chassis system. The drive-by-wire chassis system comprises a drive-by-wire steering system, a drive-by-wire braking system, a drive-by-wire driving system and a drive-by-wire suspension system; according to the invention, the fault condition of the chassis system is accurately judged through the diagnosis and grading strategy of the system full-state information fusion, the advantages and characteristics of the chassis layout are utilized, and a dual-control system monitoring mode and a redundancy and safety control mechanism of a composite part assembly are adopted; the problem that interruption or failure is caused by the fact that tasks are affected in a fault or abnormal state is solved. Through complementary advantages of hardware layout and software strategy of each system of the chassis, fault information is diagnosed, decided and controlled, and a high-safety and strong-continuity integrated system for pure electric drive-by-wire chassis layout, communication and information control and judgment is established.

    本发明属于线控化底盘控制技术领域,具体涉及一种多自由度线控化底盘冗余与安全控制系统,包括:线控化底盘控制器、线控化底盘系统;所述线控化底盘系统包括:线控转向系统、线控制动系统、线控驱动系统、线控悬架系统;本发明通过系统全状态信息融合进行诊断与分级策略实现底盘系统的故障情况的精准判断,利用底盘布局优势和特点,采用双控制系统监控方式与复合部组件的冗余与安全控制机制,解决在故障或异常状态下任务受到影响而导致中断或失败的问题。通过底盘各系统硬件布局与软件策略优势互补,对故障信息进行诊断、决策、控制,建立了一种纯电动线控化底盘布局、通信、及信息控制与判断的高安全性、强持续性的集成系统。
