The invention provides a vehicle deceleration control method, a vehicle deceleration control system and a vehicle. The vehicle deceleration control method comprises the following steps: identifying a deceleration brake signal; judging whether a brake collision risk exists or not based on generation or disappearance of the deceleration brake signal; and if the brake collision risk exists, opening the speed brake. Therefore, in the running process of the vehicle, it can be judged that the brake collision risk exists based on generation of the deceleration brake signal, and the speed brake is opened to conduct auxiliary deceleration brake; and if it is judged that the brake collision risk still exists based on disappearance of the deceleration braking signal, the deceleration plate is opened for auxiliary deceleration braking, so that the deceleration braking effect of the vehicle is improved, and the problems that the deceleration braking effect of the vehicle is poor and the rear-end collision risk still exists when the vehicle is directly subjected to deceleration braking through the brake pedal are solved. And inaccurate judgment or misoperation and the like of a driver are avoided, the risk of rear-end collision still exists under the condition that pressing of the brake pedal is relieved, and the safety of vehicle driving is further improved.

    本发明提供了一种车辆减速控制方法、车辆减速控制系统及车辆。所述车辆减速控制方法包括:识别减速制动信号;基于减速制动信号的产生或消失,判断是否存在刹车碰撞风险;判断存在刹车碰撞风险,则打开减速板。这样,在车辆行驶过程中,可以基于减速制动信号的产生,判断存在刹车碰撞风险,则打开减速板进行辅助减速制动;也可以基于减速制动信号的消失,判断仍然存在刹车碰撞风险,则打开减速板进行辅助减速制动,从而提高车辆的减速制动的效果,避免直接通过刹车踏板对车辆进行减速制动效果不佳,依然存在追尾风险的问题,也避免了驾驶员判断不准或者误操作等,在解除对刹车踏板按压的情况下仍存在追尾的风险,进一步提高了车辆驾驶的安全性。
