The invention provides a control method for regenerative torque of a vehicle with a single pedal mode, and in regenerative braking of the single pedal mode, the control method comprises the following steps: step S11, continuously acquiring an opening value of a throttle valve, a moment corresponding to the acquired opening value, a state of a traction control system and target regenerative torque; s12, when the opening degree of the throttle valve is increased and the increasing amount of the opening degree of the throttle valve is larger than a preset opening degree threshold value within the preset time, the step S13 or S14 is executed according to the state of the traction force control system; s13, when the traction force control system is in a non-starting state, the target regeneration torque is corrected, and the corrected target regeneration torque obtained after correction is smaller than the target regeneration torque and larger than 0; and S14, when the traction force control system is in the started state, the target regeneration torque is set to be 0. The invention further provides a regenerative torque control device, system and computer program product for the single pedal mode vehicle.

    本申请提供一种具有单踏板模式车辆再生扭矩的控制方法,在单踏板模式再生制动中,该控制方法包括步骤S11:持续获取节气门开度值以及所获取到的开度值所对应的时刻、牵引力控制系统的状态和目标再生扭矩;步骤S12:当节气门开度增加且在小于预设的时间内节气门开度增加量大于预设的开度阈值时,根据牵引力控制系统的状态执行步骤S13或S14;步骤S13:当牵引力控制系统处于未启动状态时,对所述目标再生扭矩进行校正,校正后得到的校正目标再生扭矩小于目标再生扭矩、大于0;步骤S14:当牵引力控制系统处于已启动状态时,将所述目标再生扭矩设置为0。本申请还提供一种用于单踏板模式车辆再生扭矩控制装置、系统及计算机程序产品。
