Active control method of high-speed tire-burst vehicle

Abstract

The invention discloses an active control method of a high-speed tire-burst vehicle. On the basis of differential braking and active front wheel steering, in combination with the influences of tire rim disengagement, the tire-burst vehicle is actively controlled. By controlling non-tire-burst tires and exerting the additional yawing moment to counteract the yawing moment and impact generated during tire bursting, the driving safety after vehicle tire bursting is improved. A whole system comprises an external environment sensing layer, a vehicle state information collecting treatment layer, a steering and braking decision making layer and an executing layer.

Description

Technical field:

[0001] The invention belongs to the field of active safety of automobiles, and in particular relates to an active control method for automobiles with high-speed punctured tires, aiming at improving the driving safety of automobiles with punctured tires and reducing or avoiding the occurrence of secondary accidents. Background technique:

[0002] A tire blowout seriously threatens the life safety of passengers, and a high-speed tire blowout is even more serious. According to statistics and investigations, the number of deaths caused by tire blowouts accounts for 49.81% of the total number of traffic accident deaths, the number of injured people accounts for 63.94%, and the proportion of direct property losses is as high as 43.38%.

[0003] As the only part of the car in contact with the road, tires not only carry the weight of the car body, buffer and absorb the impact and vibration of the road, but also provide the longitudinal and tangential forces required...

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] refer to figure 1 , the whole system includes four modules: external environment perception layer, vehicle information collection and processing layer, braking and steering decision-making layer and execution layer. Among them, the external environment perception layer mainly obtains road and environmental information, including road conditions, wind resistance and surrounding road conditions, etc., and transmits the perception information to the next level. The vehicle information collection and processing layer includes three units: body state monitoring, tire state monitoring, and vehicle state signal processing; among them, the tire detection unit is equipped with a tire bead off sensor; the vehicle state signal processing unit classifies the external environment information and vehicle state at the same time Extraction, to judge whether the vehicle has a p...
