The invention discloses a hybrid electric vehicle and a target gear control method and device thereof. The target gear control method comprises the steps of acquiring a current working mode, a currentgear lever position and a current driving mode of a hybrid electric vehicle, wherein the working mode includes an EV mode and an HEV mode, and the driving mode includes a motion mode and a non-motionmode; determining an engine target gear, an odd shaft target gear, a motor target gear and an even shaft target gear according to the current working mode, the current gear lever position and the current driving mode; and controlling a dual-clutch transmission according to the engine target gear, the odd shaft target gear, the motor target gear and the even shaft target gear. According to the target gear control method, target gear control is performed on the hybrid electric vehicle from the perspective of the whole vehicle, and therefore a dynamic property, economical efficiency, drivabilityand an emission characteristic of the hybrid electric vehicle can be well improved.

    本发明公开了一种混合动力汽车及其目标档位控制方法、装置。其中,目标档位控制方法包括获取混合动力汽车的当前工作模式、当前档杆位置和当前驾驶模式,其中,工作模式包括EV模式和HEV模式,驾驶模式包括运动模式和非运动模式;根据当前工作模式、当前档杆位置和当前驾驶模式,确定发动机目标档位、奇数轴目标档位、电机目标档位和偶数轴目标档位;根据发动机目标档位、奇数轴目标档位、电机目标档位和偶数轴目标档位对双离合变速器进行控制。该目标档位控制方法,通过从整车角度对混合动力汽车进行目标档位控制,从而能够很好的改善混合动力汽车动力性、经济性、驾驶性和排放特性。
