The invention relates to a hybrid vehicle and a method of controlling creep torque of the hybrid vehicle. The hybrid vehicle includes a first motor connected to an engine, a second motor directly connected to a transmission input, and an engine clutch connected to an engine shaft and the second motor. The method for controlling creep torque includes the steps of: determining an expected charging power expected when a target creep torque is generated by regenerative braking of a second motor; in a case where the expected charging power is equal to or greater than the battery charging limit power, idling the engine by the first motor when the engine clutch is disengaged, thereby discharging the battery; and generating the target creep torque by regenerative braking of the second motor.

    本公开涉及一种混合动力车辆及控制混合动力车辆的爬行扭矩的方法,该混合动力车辆包括:连接到发动机的第一马达、直接连接到变速器输入端的第二马达以及连接到发动机轴和第二马达的发动机离合器。用于控制爬行扭矩的方法包括以下步骤:确定在通过第二马达的再生制动产生目标爬行扭矩时预期的预期充电功率;在预期充电功率等于或大于电池充电极限功率的情况下,在发动机离合器分离时通过第一马达使发动机空转,从而使电池放电;以及通过第二马达的再生制动产生目标爬行扭矩。
