The invention belongs to the field of vehicle automatic driving, and relates to a redundant power-assisted steering system and a vehicle, the redundant power-assisted steering system comprises a combination of two power supplies, a winding motor and a control unit, and the power supplies are coupled with the winding motor through the control unit; the combination of the two torque sensors, the motor position sensor and the CAN bus is used for providing steering signals. According to the redundant power-assisted steering system and the vehicle, under the condition that any power supply, the winding motor and the control unit fail, the other power supply and the control unit are adopted to drive the winding motor so as to provide 1/2 steering assistance; and/or under the condition that any signal provided by the torque sensor, the motor position sensor and the CAN bus is lost, the other signal is adopted to provide full assistance.
本申请属于车辆自动驾驶领域,涉及一种冗余助力转向系统及车辆,包括:两路电源、绕组电机、控制单元的组合,电源通过控制单元耦接与绕组电机;两路扭矩传感器、电机位置传感器、CAN总线的组合,用于提供转向信号。本申请提供的冗余助力转向系统及车辆,在任意一路电源、绕组电机、控制单元失效的情况下采用另一路电源和控制单元驱动绕组电机以提供1/2的转向助力;和/或在任意一路扭矩传感器、电机位置传感器、CAN总线提供的信号丢失的情况下,采用另一路信号提供全助力。
