The invention relates to a control method, system and device for a vehicle to pass through a deceleration strip and a medium. The method comprises the steps that the front wheel speed condition when the vehicle runs is obtained; determining a deceleration strip recognition condition based on the front wheel speed condition; restraining the reverse towing torque control function of the vehicle based on the recognition condition of the deceleration strip, and recording the restraining duration; the rear wheel speed condition of the vehicle is obtained, and based on the deceleration strip recognition condition and the rear wheel speed condition, the quit restraining duration is obtained; and based on the suppression duration and the suppression quit duration, the reverse towing torque control function of the vehicle is recovered. The problem that in the prior art, a DTC function is prone to being triggered by mistake when a vehicle passes through a deceleration strip, the probability that a driver feels deceleration loss feeling and deceleration sudden increase feeling in the driving process is increased, and consequently the driving experience feeling is poor is solved.

    本申请涉及一种车辆通过减速带的控制方法、系统、设备及介质,方法包括:获取车辆行驶时的前轮轮速情况;基于前轮轮速情况确定减速带识别情况;基于减速带识别情况对车辆的倒拖扭矩控制功能进行抑制,并记录抑制持续时长;获取车辆的后轮轮速情况,并基于减速带识别情况和后轮轮速情况,得到抑制退出时长;基于抑制持续时长和抑制退出时长,对车辆的倒拖扭矩控制功能进行恢复。解决了现有技术中车辆通过减速带易误触发DTC功能,增大驾驶过程中驾驶员感受到减速度丢失感和减速度突增感的概率,导致驾驶体验感很差的问题。
