Vehicle control method and system and vehicle

Abstract

The invention provides a vehicle control method and a system and a vehicle. The control method comprises the following steps: when a vehicle has a flat tire, an electric assistance steering system, an engine control module and a vehicle body electronic stabilizing system are started to automatically control the vehicle; the electric assistance steering system controls a rotating angle of a steering wheel according to a predicted driving trajectory before tire burst, so that the vehicle is maintained on the predicted driving trajectory before tire burst; the engine control module limits an output torque of an engine according to a preset safety torque threshold; and the vehicle body electronic stabilizing system distributes the braking force applied to each wheel according to a target punctured tire to control stable braking of the vehicle. The method can automatically control the vehicle to keep reasonable driving trajectory after tire burst, and stably reduces the speed to improve the safety and the reliability of the vehicle when the vehicle has a flat tire.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, system and vehicle. Background technique [0002] A tire blowout is usually an emergency failure that bursts suddenly because the mechanical strength of a certain part of the tire is severely weakened, and the tire pressure is out of balance. When a vehicle blows out during high-speed driving, the car may have severe sideslips, tail flicks, or even overturning accidents, which not only endangers the safety of the vehicle and personnel with the blown tire, but more seriously, the high-speed vehicles cannot avoid it in time. , It is likely to cause multiple vehicles to collide, causing major traffic accidents. Therefore, how to improve vehicle safety is an urgent problem to be solved when a tire blowout occurs in a vehicle. Contents of the invention [0003] In view of this, the present invention aims to propose a vehicle control method, which can ...
