The invention discloses an automatic returning device and method for automobile parking. The automatic returning device comprises a control panel, a steering wheel torque/angle sensor, a CKP/CMP sensor, a gear sensor, a steering transmission shaft, a planetary gear mechanism, a rotating air cylinder, a worm and an electromagnetic reversing valve. The planetary gear mechanism is respectively in driving connection with the steering transmission shaft and the worm; one end of the worm is fixedly connected with the end part of a piston rod of the rotating air cylinder; the rotating air cylinder is connected with the inner side of the throttle valve through an electromagnetic directional valve; the control panel is connected with the steering wheel torque/angle sensor, the CKP/CMP sensor, the gear sensor and the electromagnetic reversing valve. The method comprises the steps of determining that a gear is a parking gear and a vehicle is in a flameout state, and enabling the engine air inlet pipe to drive the rotating air cylinder to drive the worm to rotate through negative pressure, and completing returning. The steering wheel can return after parking, the influence of non-returning on automobile parts is effectively avoided, lateral scraping during starting is avoided, and the device can also be used as a power-assisted steering device in the driving process.

    一种汽车停车自动回正装置及方法,包括控制板、转向盘转矩/角度传感器、CKP/CMP传感器、挡位传感器、转向传动轴、行星齿轮机构、旋转气缸、涡杆和电磁换向阀;行星齿轮机构分别与转向传动轴与涡杆驱动连接;涡杆的一端与旋转气缸的活塞杆端部固定连接,旋转气缸通过电磁换向阀与节气门内侧连接;控制板分别与转向盘转矩/角度传感器、CKP/CMP传感器、挡位传感器和电磁换向阀连接。方法:确定挡位处于驻车档且车辆处于熄火状态;发动机进气管负压驱动旋转气缸带动涡杆旋转,完成回正。该发明能实现停车后方向盘回正,有效避免未回正对汽车部件产生的影响,利于避免启动时发生侧向刮擦,该装置还可作为行车过程中的助力转向装置。
