The invention discloses a multi-source coupling sliding plate chassis system and a multi-level fault-tolerant control method thereof. The system comprises a drive-by-wire subsystem, an electro-hydraulic composite steering-by-wire subsystem, an electric composite brake-by-wire subsystem, a multi-level fault observation unit and a multi-level fault-tolerant control unit. All-wheel driving, steering, braking and other systems are integrated, independent development of an upper vehicle body and a lower chassis can be achieved, the convenience of vehicle manufacturing is greatly improved, meanwhile, a multi-level integrated and coordinated fault-tolerant control method is provided, the safety of the whole vehicle is improved, and the whole vehicle can meet the ASIL-D level multi-safety requirement.
本发明公开了一种多源耦合滑板底盘系统及其多层级容错控制方法,系统包括:线控驱动子系统、电液复合线控转向子系统、电气复合线控制动子系统、多层级故障观测单元及多层级容错控制单元;本发明将全轮驱动、转向、制动等系统一体化集成,可实现上装车身与下装底盘的独立开发,极大程度增强车辆制造的便利性,同时提出了多层级集成协调的容错控制方法,提高了整车安全性,使其可以满足ASIL‑D级多重安全的要求。
