The invention provides a backflow preventing system and method for a vehicle exhaust pipe and a vehicle. The system comprises a sensor and a backflow preventing module, wherein the sensor senses the wading condition of the vehicle; the backflow preventing module is connected with the sensor and receives the wading condition, which is sensed by the sensor, of the vehicle; the backflow preventing module further interacts with a vehicle power assembly; and the backflow preventing module operates based on the wading condition of the vehicle to increase the rotating speed of an engine in the powerassembly, and therefore, the exhaust amount of the exhaust pipe is increased. According to the system of an embodiment of the invention, water can be prevented from flowing back through the exhaust pipe as much as possible when the vehicle wades.
本发明提供了一种用于车辆排气管的防逆流系统和方法以及车辆。所述系统包括:传感器,所述传感器感测车辆涉水情况;防逆流模块,所述防逆流模块与所述传感器连接并接收所述传感器感测到的车辆涉水情况,并且,所述防逆流模块还与车辆动力总成交互,所述防逆流模块基于所述车辆的涉水情况操作以提高所述动力总成中的发动机转速,由此增加通过排气管的排气量。根据本发明的实施例的系统能够在车辆涉水时尽可能阻止水通过排气管逆流。
