Abstract

The invention relates to a control method, a control device and a vehicle suitable for vehicle tire burst, which includes: judging whether the vehicle has a tire burst according to the vehicle tire burst signal; if so, controlling the steering assist motor to generate a preset steering resistance torque, and A preset braking torque is applied to the rear axle wheels of the vehicle, and at the same time, the driving torque of the vehicle is controlled to be reduced to 0 or the minimum idling torque. The invention relates to a control method, a control device and a vehicle suitable for a vehicle tire blowout. The steering resistance torque and braking torque are used instead of resistance or power parameters for monitoring and adjustment, which can prevent the vehicle from turning unstable at the moment of a tire blowout. The direction is deflected quickly, and at the same time, controlling the driving torque of the vehicle can assist the braking of the whole vehicle to a certain extent.

Description

technical field [0001] The invention relates to the technical field of vehicle safety driving, in particular to a control method, a control device and a vehicle suitable for vehicle tire burst. Background technique [0002] At present, accidents caused by tire blowouts remain high among expressway accidents. Those with milder consequences of tire blowouts will cause the vehicle to lose its normal driving state, the steering wheel will lose control, and the vehicle will drift; in severe cases, the vehicle will completely lose control and flick , U-turn. High-speed tire blowout is considered to be the number one killer of safety under dynamic driving conditions. At the same time, this is also a major problem that major automobile OEMs and suppliers at home and abroad are striving to solve. [0003] In the related art, there is a method for controlling the direction of a vehicle after a tire blowout, which is to obtain the tire pressure information of the vehicle and determine...
