The invention discloses a pure electric commercial vehicle creeping and slope sliding prevention integrated control method and system, and relates to the field of pure electric commercial vehicle control. The method comprises the steps: judging whether a vehicle currently has a vehicle sliding sign or not based on gear information and a motor rotating speed: entering a slope sliding prevention mode if the vehicle sliding sign exists, and controlling the motor rotating speed and the motor torque to be 0; if no vehicle sliding sign exists, judging whether the vehicle is in a starting state; if not, entering a normal driving mode, if yes, entering the starting mode, controlling the rotating speed of the motor to be 0, judging the road state when the vehicle is started after the vehicle is started, if yes, entering a creeping mode, controlling the initial speed of the vehicle to be a preset speed, and if the road state is the slope, entering a slope sliding prevention mode, and controllingthe rotating speed of the motor and the torque of the motor to be 0. The safety and the comfort of vehicle driving can be effectively improved.
本发明公开了一种纯电商用车蠕行和防溜坡集成控制方法及系统,涉及纯电商用车车辆控制领域,该方法包括基于档位信息和电机转速判断车辆当前是否存在溜车迹象:存在溜车迹象,则进入防溜陂模式,控制电机转速和电机扭矩均为0;不存在溜车迹象,则判断车辆是否处于起步状态,若不处于,则进入正常行驶模式,若处于,则进入起步模式,控制电机转速为0,并待车辆起步后,判断车辆起步时的道路状态,若为平地,则进入蠕行模式,控制车辆初始速度为预设速度,若为坡道,则进入防溜陂模式,控制电机转速和电机扭矩均为0。本发明能够有效提高车辆驾驶的安全性和舒适性。
