Automotive steering control system and control method thereof

Abstract

The invention relates to an automotive steering control system and a control method thereof. The automotive steering control system comprises a planetary gear train device mounted between a steering wheel and an automotive steering transmission mechanism, a camera arranged in the front of an automobile and radar arranged on two sides of the automobile, wherein an automobile ECU is separately in communication connection to the planetary gear train device, the camera and the radar; the camera monitors lines on two sides of a travelling lane; the camera sends the photographed line information to the automobile ECU and the radar emits a radar signal to the back of the steering side and transfers the back automobile distance information to the automobile ECU, and the automobile ECU controls the planetary gear train device to be started or stopped; and the planetary gear train device realizes low-speed auxiliary steering or high-speed restricted steering of the automobile. The system provided by the invention plays a steering protecting role in different travelling states, so that the automobile is more safely and reliably steered.

Description

technical field [0001] The invention relates to an automobile steering control system and a control method thereof, belonging to the technical field of automobile steering. Background technique [0002] When driving at low speeds, entering and exiting parking spaces, and turning around, drivers often turn the steering wheel at a large angle when turning. And in order not to hurt the tire, the steering wheel is often played while the vehicle is moving. At this time, due to the large angle of rotation of the steering wheel, some drivers cannot turn the steering wheel to the ideal position when the vehicle is moving, and understeer occurs, which causes the vehicle to scratch or even collide with pedestrians, resulting in accidents. When driving at high speed, especially on the expressway, the slight negligence of the driver and the slight rotation of the steering wheel will often lead to a large lateral movement of the vehicle, which not only easily collides with the rear vehi...

AI Technical Summary

Problems solved by technology

At this time, due to the large angle of rotation of the steering wheel, some drivers cannot turn the steering wheel to the ideal position when the vehicle is moving, and understeer occurs, which causes the vehicle to scratch or even collide with pedestrians, resulting in accidents

When driving at high speed, especially on the expressway, the slight negligence of the driver and the slight rotation of the steering wheel will often lead to a large lateral movement of the vehicle, which not only easily collides with the rear vehicle, but also scratches the guardrail and the vehicle itself. risk of rollover
