A kind of anti-fall control method of automobile winding road

Abstract

The invention discloses an automobile sky way anti-falling control method. The method includes the following steps that firstly, travel information is obtained according to an automobile-mounted sensing system and comprises the automobile speed Vr, the acceleration ar and the front wheel turning angle alpha, and the distance between an automobile and the boundary of a sky way is measured; secondly, according to the information obtained from the first step, an automobile sky way anti-falling model equation is established; thirdly, the automobile sky way anti-falling model equation is solved and calculated, so that the anti-falling early warning distance Dw and the steering delay braking distance Ds are obtained; fourthly, the distance Lrelative between the automobile and the edge of a front right cliff is compared with the corresponding anti-falling early warning distance Dw and the corresponding steering delay braking distance Ds, an adopted anti-falling mode is judged; and fifthly, after the unit time interval, data are measured again, and the first step to the fourth step are repeated. By the adoption of the method, boundary information of the sky way is detected in real time, and the automobile sky way anti-falling model equation is dynamically established through the obtained data, so that an established model is pertinent, and the anti-falling success rate is remarkably increased.

Description

technical field [0001] The invention relates to an anti-drop control method on a winding mountain road for automobiles, and belongs to the technical field of driving safety. Background technique [0002] With the vigorous development of the automobile industry, automobiles have been applied in various fields, among which the passenger and freight vehicles on Panshan Highway are one of the important branches. However, the risk factor of cars on winding mountain roads is much higher than that on ordinary roads, and the danger of falling off cliffs always exists: at 23:00 on March 2, 2015, a serious traffic accident occurred on the winding mountain road in Xiaohushan, Wulong Town, Linzhou, Henan. A bus from Xinxiang City, Henan Province to Linzhou City had a traffic accident at the junction of the two cities (Provincial Highway S226 Highway 45+800 meters) and fell down a 100-meter deep cliff, killing 20 people and injuring 13. Such tragic examples are too numerous to enumerate...
