The invention provides a power-assisted pushing control system and method for an electric vehicle. The power-assisted pushing control system comprises a temple sensor, a cushion sensor, a gyroscope, an intelligent center controller and a motor controller. The temple sensor detects the temple state, and the temple state comprises folding and unfolding; the cushion sensor detects the cushion state of the electric vehicle; the gyroscope detects the body posture of the electric vehicle; the motor controller detects the running speed of the electric vehicle; the intelligent central controller judges whether the electric vehicle is in a power-assisted pushing mode according to the temple state, the cushion state and the running speed, if yes, sends speed limiting instruction information to the motor controller, and the P-gear key is removed; when the posture of the vehicle body is uphill, power assisting instruction information is sent to a motor controller, so that the motor controller outputs power according to the power assisting instruction information; whether the vehicle is in the power-assisted pushing mode is automatically recognized, various dangers such as vehicle channeling, vehicle sliding and inconsistent pedestrian and vehicle pace in the pushing process can be effectively avoided, meanwhile, power is automatically output for power-assisted pushing on the uphill road section, and the user experience is improved.
本发明提供了电动车的助力推行控制系统和方法,包括:边撑传感器、坐垫传感器、陀螺仪、智能中控和电机控制器;边撑传感器检测边撑状态,边撑状态包括收起和展开;坐垫传感器检测电动车的坐垫状态;陀螺仪检测电动车的车身姿态;电机控制器检测电动车的行驶速度;智能中控根据边撑状态、坐垫状态和行驶速度,判断电动车是否处于助力推行模式,若是,则向电机控制器发送限速指令信息,解除P档按键;当车身姿态为上坡时,向电机控制器发送助力指令信息,以使电机控制器根据助力指令信息输出动力;自动识别车辆是否为助力推行模式,能有效避免推行中的窜车、溜车、人车步调不一致等各种危险,同时在上坡路段自动输出动力助力推行,提高用户体验。
