Crosswind can appear in some wind gaps or wide areas, and reminds a driver that strong crosswind exists in front of the driver.

The violent vibration generated during the running of the automobile is transmitted to a driver, so that the difficulty of controlling the direction is increased.

The new design of the steering wheel is developed, and the gear system introduced between the driver and the wheels is flexible to operate and well isolates severe vibration from the road. Moreover, a good steering wheel system can bring a feeling of intimacy with the road to the driver. In the prior art, crosswind is one of important factors causing potential safety hazards to a vehicle, the crosswind can drive the vehicle to horizontally move, if a driver does not stabilize a steering wheel at the moment, the vehicle is easily increased in horizontal movement amplitude, and further safety accidents occur, and meanwhile, if a violent horizontal steering driving strategy for resisting the crosswind is adopted in the crosswind state, accidents of tire bulging and even tire burst can also occur.
