Telescopic steering wheel and control method thereof

Abstract

The invention discloses a telescopic steering wheel. The telescopic steering wheel comprises a road feeling motor, a steering shaft, a steering shaft sleeve, a shell body, an adjusting motor and a supporting limiting block, wherein the steering shaft is composed of three coaxially and fixedly connected assembly units, the first assembly unit and the second assembly unit are correspondingly locatedat the two ends of the third assembly unit, and even annular gear racks are arranged on the surface of the third assembly unit; the steering shaft sleeve is a hollow cuboid with central through holeson the upper side and the lower side, through hole slideways are arranged on the both sides of the steering shaft sleeve, and the steering shaft is located in the steering shaft sleeve; the shell body is of a groove profile structure with an inner concave center, and a supporting plate extends out of the central position of the edge of the concave groove of one side of the shell body; the adjusting motor is fixedly connected to the upper part of the supporting plate of the shell body, an output shaft is arranged on one side of the adjusting motor, and a gear shaft is fixedly connected to thehead of the output shaft; and the two sides of the supporting limiting block are fixedly connected with the two sides of the inner concave groove of the shell body, and the middle of the supporting limiting block passes through the two side slideways of the steering shaft sleeve. The invention further provides a control method of the telescopic steering wheel, and the scalability of the steering wheel can be controlled according to the manual driving state or the unmanned driving state.

Description

technical field [0001] The invention relates to the field of steering by wire and unmanned driving, in particular to a retractable steering wheel and a control method thereof. Background technique [0002] Steering by wire can realize fast steering of the vehicle. Direct digital signal input is used from the steering wheel to the steering actuator. There are no mechanical parts such as steering universal joints in the entire system that may cause "steering delay". The driver's driving intention can be quickly judged to achieve more flexible steering, and the driving experience is more direct. The steering wheel can filter out the impact from the ground on the front wheels. [0003] Unmanned vehicles are the product of highly developed computer science, pattern recognition and intelligent control technology, and are also an important symbol to measure a country's scientific research strength and industrial level. It has broad application prospects in the fields of national de...
