Problems solved by technology

[0004] The existing automobile steering system mainly adopts the power steering system. When the steering system turns, only a small part of the steering power source is provided by the driver, and most of it is provided by hydraulic pressure or motor torque, but the intelligence in lateral control is not high. Can't better provide effective technical support for higher-level intelligent driving

Abstract

The invention discloses a steer-by-wire control method. The steer-by-wire control method comprises the following steps that S1, an electric control steering engine is activated; S2, switching to an external control state; s3, the intelligent driving controller sends out a corresponding steering wheel angle signal or a torque value signal according to the switched steering mode; s4, the vehicle control unit receives a steering wheel angle signal or a torque value signal from the intelligent driving controller and controls the electric control steering engine; s5, the electric control steering engine executes a command sent by the intelligent driving controller; s6, a motor controller of the electric control steering engine sends out a feedback signal to feed back the working state of the electric control steering engine; s7, the electric control steering engine self-checks the working state and sends the working state to the vehicle control unit in the form of a private message; and S8,after receiving the fault state of the steering engine, the vehicle control unit switches the working state of the steering engine and feeds back the working state to a corresponding display device.Transverse control over the vehicle is achieved, and the transverse control requirement of intelligent driving is met.

Description

technical field [0001] The invention relates to a steering-by-wire control method, which belongs to the technical field of steering control of automobiles. Background technique [0002] The function of the car steering system is to control the driving direction of the car according to the driver's wishes. The car steering system is very important to the driving safety of the car. [0003] With the development of intelligent connected vehicles and steering systems, the lateral control of the vehicle is realized by using the controller to control the steering system. In the field of intelligent driving, the realization of lateral control and longitudinal control of the vehicle is the prerequisite for realizing a higher level of intelligent driving. In the field of commercial vehicle design, the control system is used to send control signals to the steering system, and the steering system executes the corresponding steering commands by receiving the control signals from the co...
