Control system and control method for preventing steering wheel from rotating during automobile collision and automobile

Abstract

The invention relates to the technical field of automobile manufacturing, and particularly discloses a control system and control method for preventing a steering wheel from rotating during an automobile collision and an automobile. An electric control unit of a safety system and an electric power-assisted steering system in the control system are electrically connected, and data transmission andexchange are realized so that the electric power-assisted steering system can identify and receive the safety system ignition instruction during automobile collision, and the steering of the steeringwheel can be locked; and the electric power-assisted steering system is further electrically connected with a data communication bus, and can receive the vehicle speed signal sent by the data communication bus and release the steering of the steering wheel. Due to the adoption of the control system, the phenomenon that the steering wheel rotates along with the wheel deflection during automobile collision can be avoided, so that the protection effect of the airbag is improved. In addition, the control system does not add additional components, only the existing vehicle body system is utilized for functional integration, and the control method is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a control system, a control method and an automobile for preventing a steering wheel from rotating when an automobile collides. Background technique [0002] With the increasing popularity of automobiles, traffic accidents are gradually increasing. The safety airbag in the car is a kind of passive safety protection system, which is used in conjunction with the seat belt to provide effective anti-collision protection for the occupants. When a car collides, the airbag can effectively protect the head and chest of the human body, so as to prevent or reduce the degree of injury. The anti-collision airbag on the driver's side is arranged in the steering wheel, and the anti-collision airbag on the passenger's side is generally arranged on the instrument panel.

AI Technical Summary

Problems solved by technology

[0003] In the event of a car collision with existing automotive products, the steering wheel often rotates to varying degrees with the deflection of the wheels, which causes the position of the driver's side airbag to shift, which in turn leads to a decrease in the protection effect and affects the safety of the driver.
