The embodiment of the invention relates to the technical field of vehicles, in particular to a vehicle auxiliary power system and a vehicle. The system comprises a gradient detection assembly, a pedal sensing assembly, a control assembly, a motor folding and unfolding assembly, a hub motor and an energy storage assembly. Wherein the control assembly is used for obtaining gradient data collected by the gradient detection assembly and pedal state information, collected by the pedal sensing assembly, of the vehicle, and when the gradient data indicates that the vehicle is in a downhill state and the pedal state information indicates that the vehicle is in a braking state, the motor folding and unfolding assembly is controlled to put down the hub motor; the wheel body of the hub motor is in contact with the ground, the hub motor is controlled to generate reverse torque to assist vehicle braking, and electric energy generated by rotation of the wheel body is transmitted to the energy storage assembly to be recycled. The vehicle auxiliary power system assists the vehicle in braking, the duration and strength of braking of the vehicle through the brake pad can be reduced, and the situation that the brake pad is overheated is avoided.
本公开的实施例涉及车辆技术领域,具体涉及一种车辆辅助动力系统和车辆。前述系统包括坡度检测组件、踏板感应组件、控制组件、电机收放组件、轮毂电机以及储能组件。其中,控制组件用于获取坡度检测组件采集的坡度数据和踏板感应组件采集的车辆的踏板状态信息,在坡度数据表示车辆处于下坡状态,且踏板状态信息表示车辆处于制动状态时,控制电机收放组件放下轮毂电机,以使轮毂电机的轮体与地面接触,控制轮毂电机产生反向的扭矩以辅助车辆制动,且将轮体转动产生的电能传递至储能组件以进行电能回收。通过车辆辅助动力系统辅助车辆进行制动,能够减小车辆利用刹车片制动的时长和力度,避免刹车片过热的情况。
