The invention provides an intelligent sliding energy recovery control method for a pure electric vehicle, which comprises the following steps of: performing signal interaction on a sliding energy recovery control system and an intelligent driving system to obtain the speed and distance information of a front vehicle or an obstacle. And calculating the distance between the vehicle and the front vehicle or the front obstacle and the relative vehicle speed according to the speed and distance information of the front vehicle or the front obstacle. And when the relative vehicle speed is larger than a calibration limit value, it is judged that the vehicle is in a free sliding state, and the sliding energy recovery torque is controlled to be 0. And when the relative vehicle speed is smaller than the calibration limit value, recovery control is conducted according to the set minimum sliding energy recovery torque. The deceleration of the whole vehicle during sliding deceleration of the vehicle can be adjusted more intelligently, energy recovery to a greater extent is achieved, and the energy-saving performance and intelligence of the vehicle are improved.
本发明提供一种纯电动汽车智能滑行能量回收控制方法,包括:将滑行能量回收控制系统与智能驾驶系统进行信号交互,以获取前方车辆或障碍物的速度及距离信息。根据前方车辆或障碍物的速度及距离信息计算得到自车与前车或前方障碍物的距离及相对车速。当所述相对车速大于标定限值,判定自车处于自由滑行状态,控制滑行能量回收扭矩为0。当所述相对车速小于所述标定限值时,按设定的最小滑行能量回收扭矩进行回收控制。本发明能更加智能调节车辆滑行减速时的整车减速度,实现更大程度的能量回收,提高车辆的节能性和智能性。
