The invention relates to the field of dual-clutch transmissions, in particular to a method for judging the driving direction of a vehicle, which comprises the following steps of: 1) dismounting an output shaft rotating speed sensor in a DCT (dual clutch transmission), and mounting an input shaft rotating speed sensor with a function of identifying the wheel speed direction; and (2) in the vehicle driving process, whether the vehicle ABS breaks down or not is judged, if not, the vehicle driving direction is judged by means of the vehicle ABS, and if yes, the vehicle driving direction is judged by means of the rotating speed direction of the input shaft. According to the method, the cost is reduced by canceling an output shaft rotating speed sensor, and the driving direction of the vehicle can be accurately recognized through the DCT control system under the condition that no ABS exists, so that the combination mode of the clutch is judged, and accidents are avoided.
本发明涉及双离合变速器领域,具体涉及一种判断车辆行驶方向的方法,包括以下步骤:1)拆除DCT中的输出轴转速传感器,并安装具有识别轮速方向功能的输入轴转速传感器;2)在车辆行驶过程中,判断汽车ABS是否发生故障,若没有发生故障,则依靠汽车ABS对车辆行驶方向进行判断,若发生故障,则利用输入轴转速方向来判断车辆行驶方向。本发明不但通过取消输出轴转速传感器降低了成本,还能够在没有ABS的情况下,通过DCT控制系统准确识别车辆行驶方向,用于判断离合器的结合方式,避免事故发生。
