Automatic driving vehicle risk avoiding control method and system and computer storage medium

Abstract

The invention relates to a risk avoiding control method and system for an automatic driving vehicle and a computer medium, the risk avoiding control method and system are used for a road section where a guardrail is arranged on a highway and roadside is provided with a roadblock facility, the roadblock facility is provided with a plurality of columnar anti-collision barrels arranged on the roadside side by side, and the method comprises the steps that parameters of the anti-collision barrels and static parameters of the vehicle are obtained, the parameters of the anti-collision barrel comprise the rotational inertia jz of the anti-collision barrel, the radius r of the anti-collision barrel and the mass m2 of the anti-collision barrel; the vehicle static parameters comprise the vehicle mass m1 of the vehicle; the driving direction of the vehicle is controlled, so that when the vehicle collides with the anti-collision barrel, the included angle alpha between the vehicle and the anti-collision barrel meets the first formula: by controlling the driving direction of the vehicle, the included angle theta 1 between the driving direction of the vehicle and the anti-collision barrel meets the conditions, and then the vehicle can be prevented from turning around when colliding; rolling of the vehicle due to collision is reduced, and the safety of personnel in the vehicle is guaranteed.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to an automatic driving vehicle risk avoidance control method, system and computer storage medium. Background technique [0002] As we all know, autonomous driving and unmanned driving are the current and future research directions of automobiles, which have a profound impact on the automobile industry and even the transportation industry. The advent of driverless cars will liberate human hands, reduce the frequency of traffic accidents, and ensure people's safety. However, the emergence of any technology is a process of gradual and continuous innovation. From the emergence of unmanned driving to its maturity and then to its ability to be used worldwide, a series of technical challenges still need to be solved. [0003] At present, domestic companies such as Baidu and Chang'an, as well as military academies such as the National University of Defense Technology and the Milit...
