The invention discloses an uphill auxiliary system and method and an electric vehicle, the uphill auxiliary system comprises an information collection module and a motor controller, the information collection module is used for collecting vehicle state information, the motor controller is used for obtaining the vehicle state information, whether the vehicle meets an uphill auxiliary condition is judged according to the vehicle state information, and if yes, the uphill auxiliary system is started. If yes, entering an uphill auxiliary mode, and controlling a motor to provide prevention torque to prevent the vehicle from sliding on a slope; otherwise, entering a non-uphill auxiliary mode, and enabling the motor to be in an accelerator driving state. According to the method, the motor controller of the vehicle is used for judging the uphill auxiliary condition, and the control motor is driven to provide the stopping torque when the uphill auxiliary condition is met, so that the vehicle can be prevented from sliding on the slope, and the uphill auxiliary function is achieved; according to the method, a VCU is not needed, only a control strategy needs to be put into a motor controller of an existing vehicle, the structure of the vehicle is not changed, and the cost is reduced to the maximum extent.

    本发明公开了一种上坡辅助系统、方法及电动车辆,上坡辅助系统包括信息采集模块和电机控制器,信息采集模块用于采集车辆状态信息,电机控制器用于获取车辆状态信息,并根据车辆状态信息判断车辆是否满足上坡辅助条件,若是,则进入上坡辅助模式,控制电机提供阻止扭矩阻止车辆溜坡;否则,则进入非上坡辅助模式,使电机处于油门驱动状态。本申请通过利用车辆自带的电机控制器进行上坡辅助条件判断,并在满足上坡辅助条件时驱动控制电机提供阻止扭矩,即可阻止车辆溜坡,实现上坡辅助功能;本发明不需要借助VCU,只需在现有车辆都具有的电机控制器上置入控制策略即可,对车辆本身结构无改动,最大限度地降低了成本。
