The embodiment of the invention provides a tire valve, a tire, a vehicle and a method for controlling inflation and deflation of the tire valve. The tire valve comprises a shell, an in-tire air pressure sensor, a limiting piece, a valve core and a driving unit. The in-tire air pressure sensor is located at one end of the shell, the limiting piece is arranged in the shell, the limiting piece and the valve core define an internal space, and the driving unit is used for driving the valve core to move so that the external environment of the tire valve can communicate with the internal space. The pressurizing control unit is arranged at one end of the limiting piece and pressurizes the interior of the tire according to a sucking pump signal after the inner space and the outer space of the tire valve are communicated, and the depressurizing control unit is arranged at the other end of the limiting piece and depressurizes the interior of the tire according to an air pressure release signal after the inner space and the outer space of the tire valve are communicated. According to the embodiment of the invention, the internal air pressure of the tire is adjusted in real time through automatic inflation and deflation of the tire valve, the height and rigidity of the vehicle tire are automatically controlled, and the driving safety and stability are improved.

    本发明实施例提供一种轮胎气门嘴、轮胎、车辆及轮胎气门嘴充放气的控制方法,轮胎气门嘴包括壳体、胎内气压传感器、限位件、气门芯及驱动单元。胎内气压传感器位于壳体一端,限位件内置于壳体内部,且限位件与气门芯围成内部空间,驱动单元用于驱动气门芯进行运动,以使轮胎气门嘴外部环境与内部空间连通。还包括加压控制单元以及降压控制单元,加压控制单元设于限位件一端,在轮胎气门嘴内外空间连通后根据抽气泵信号向胎内加压,降压控制单元设于限位件的另一端,在轮胎气门嘴内外空间连通后根据气压释放信号向胎内降压。本发明实施例通过轮胎气门嘴自动充放气实时调整轮胎内部气压,自动控制车辆轮胎的高度及刚度,提升了行驶的安全稳定性。
