Technical Field

The invention relates to the field of automobile steering mechanisms, in particular to an intelligent network-connected automobile steer-by-wire mechanism based on multi-sensor fusion.

Background

An automotive steering system is a series of devices used to change or maintain the direction of travel or reverse of an automobile. The function of the steering system of the automobile is to control the driving direction of the automobile according to the intention of the driver. The automobile steering system is important to the driving safety of the automobile, so the automobile steering system is a system which must be considered for the automobile safety. At present, automobile steering systems are divided into two main categories: mechanical steering systems and power steering systems. Mechanical steering systems use the driver's physical strength as the steering energy source, where all force transmitting members are mechanical. The mechanical steering system consists of three parts, namely a steering control mechanism, a steering gear and a steering transmission mechanism. The power steering system is a steering system which uses both driver physical power and engine power as steering energy. Under normal conditions, only a small portion of the energy required for steering the vehicle is provided by the driver, while the majority is provided by the engine through the power steering. However, in the event of a failure of the power steering system, the driver should generally be able to undertake the steering task of the vehicle independently. Therefore, the power steering system is formed by adding a set of power steering device to the mechanical steering system.

At present, many car owners have a bad habit in driving, do not return the steering wheel after parking at the side position of the car, and easily damage the steering mechanism of the car after a long time.
