The invention provides a control method for hill starting assistance of a pure electric heavy truck, which is characterized by comprising an auxiliary starting control module, a driving control module, a braking control module and a driving motor, and the driving motor is provided with a driving motor control module; the control method comprises the steps that the auxiliary starting control module judges whether the vehicle has a sliding trend or not, if yes, the driving motor is controlled to work in a rotating speed control mode, the rotating speed of the driving motor is made to approach zero, and the auxiliary starting control module starts starting until the motor demand torque given by a driver through an accelerator pedal is larger than the motor feedback torque. And controlling the driving motor to work in a torque control mode, so that the driving motor responds to the motor demand torque and drives the vehicle to start uphill. According to the control method, obvious sliding of the pure electric heavy truck during uphill starting can be effectively avoided, safety accidents caused by sliding are reduced, and the safety of slope uphill starting of the pure electric heavy truck is greatly improved.
本发明提供了一种纯电重卡坡道起步辅助的控制方法,其特征在于:包括辅助起步控制模块、驱动控制模块、制动控制模块和驱动电机,所述驱动电机上设置有驱动电机控制模块;所述控制方法包括辅助起步控制模块判断车辆是否存在溜车趋势,如果判定车辆存在溜车趋势即控制驱动电机工作于转速控制模式,使驱动电机的转速趋近零,直到驾驶员通过油门踏板给出的电机需求扭矩大于电机反馈扭矩,控制驱动电机工作于扭矩控制模式,使驱动电机响应电机需求扭矩,驱动车辆上坡起步。本发明所述的控制方法能有效避免纯电重卡上坡起步时的明显溜车,减少了因溜车造成的安全事故,大大提高了纯电重卡坡道上坡起步的安全性。
