The invention provides a multi-axle new energy vehicle drive-by-wire chassis redundancy control system and method and a new energy vehicle, and relates to the technical field of automatic driving automobiles. According to the failure number of the driving shafts, four shafts of the whole vehicle are adjusted to work 12 * 8, three shafts of the whole vehicle are adjusted to work 12 * 6, two shafts of the whole vehicle are adjusted to work 12 * 4 and one shaft of the whole vehicle is adjusted to work 12 * 2, and torque instructions of the driving shafts in the working state are adjusted in real time to respond to an acceleration request of an automatic driving system; braking force is generated by applying torque opposite to the rotating speed direction to the driving motor currently in the working state, and kinetic energy is converted into electric energy to be stored in the power battery. Differential torque steering is achieved by controlling the torque difference of the two wheel-side motors on the same shaft. Through redundant control of driving, braking, steering and parking, function backup of the drive-by-wire chassis is achieved, and the safety of the whole vehicle is improved.

    本发明提供一种多轴新能源车辆线控底盘冗余控制系统、方法及新能源车辆,涉及自动驾驶汽车技术领域,多轴独立控制驱动模块在12×10轮边驱动车辆某些驱动轴失效时,根据驱动轴失效数量调节整车至四个轴工作12×8、三个轴工作12×6、两个轴工作12×4以及一个轴工作12×2,并实时调节处于工作状态的驱动轴的扭矩指令,来响应自动驾驶系统的加速度请求;通过对当前处于工作状态的驱动电机施加与转速方向相反的扭矩来产生制动力,把动能转换成电能储存到动力电池。本发明还通过控制同一轴两个轮边电机的扭矩差实现差矩转向。通过驱动、制动、转向、驻车的冗余控制,实现线控底盘的功能备份,提高了整车的安全性。
