The invention relates to a sliding feedback control method and system for a pure electric commercial vehicle and the vehicle. The sliding feedback control method comprises the steps that the target deceleration of the vehicle in the sliding process is determined; calculating a target feedback torque value of vehicle sliding according to the target deceleration; and controlling the vehicle to slow down according to the target feedback torque value. In the vehicle sliding process, the VCU does not use the fixed calibrated feedback torque at the fixed vehicle speed or rotating speed, but the deceleration of the optimal vehicle sliding deceleration value is calibrated on a conventional road, and the feedback torque value of vehicle sliding is calculated according to the set deceleration. The vehicle has the same trend of deceleration when the vehicle is under different mass loads or goes up and down a ramp, so that reasonable driving feelings in different states are guaranteed, and more feedback energy is obtained to an energy storage battery.
本申请涉及一种纯电动商用车的滑行回馈控制方法、系统及车辆,其包括:确定车辆滑行过程中的目标减速度;根据所述目标减速度计算车辆滑行的目标回馈扭矩值;根据所述目标回馈扭矩值控制车辆减速。由于在车辆滑行过程中,VCU不再使用固定车速或转速下的固定标定好的回馈扭矩,而是在常规公路标定出车辆滑行减速度最优值的减速度,滑行按照设定的减速度计算车辆滑行的回馈扭矩值,以达到车辆在不同质量载荷或者上下坡道时候车辆有相同趋势的减速度,从而保障不同状态的合理驾驶感,并获取更多的回馈能量至储能电池。
