The invention provides a vehicle deceleration control method and a vehicle control unit. The method comprises the following steps: judging whether a driver of a vehicle has a deceleration intention ornot at each moment according to the speed of the vehicle, the speed of a front vehicle and the relative distance between the vehicle and the front vehicle at the corresponding moment; when the deceleration intention exists, calculating the speed of the vehicle and braking the vehicle to reach the braking distance required by the speed of the front vehicle after the accelerator of the vehicle is released, and enabling the vehicle to completely slide to reach the first deceleration distance required by the speed of the front vehicle; and judging whether the vehicle needs to be decelerated or not when the speed of the vehicle is completely braked by the motor to reach a second deceleration distance for driving the vehicle ahead, and determining a deceleration mode adopted when the vehicle needs to be decelerated; and according to the determined deceleration mode and the driver take-over control mode, deceleration control is conducted on the vehicle in different deceleration stages, so that the vehicle can slide and be braked and recycled by a motor, and better fuel economy and driving safety are achieved.

    本发明提供了一种车辆减速控制方法及整车控制器,所述车辆减速控制方法针对每个时刻,根据对应时刻的本车辆车速、前方车辆车速和本车辆与前方车辆的相对距离判断本车辆驾驶员是否存在减速意图;在存在减速意图时通过计算本车辆松油门后本车辆车速制动到达前方车辆车速需要行驶的制动距离、本车辆车速完全滑行达到前方车辆车速所行驶的第一减速距离、本车辆车速完全电机制动达到前方车辆车速所行驶的第二减速距离判断本车辆是否需要减速行驶,并确定需要减速行驶时采用的减速模式;根据确定的减速模式和驾驶员接管控制的方式对不同减速阶段的本车辆进行减速控制,使得车辆可进行滑行和电机制动回收动作,实现更好的燃油经济性和驾驶安全性。
