Abstract

The invention provides a vehicle control method, a vehicle control system and an automobile. Wherein, the vehicle control method includes: step S10: acquiring the parameter signal of the vehicle; step S20: determining the running state of the vehicle according to the parameter signal; step S30: controlling the running state of the auxiliary braking device of the vehicle according to the driving state of the vehicle, wherein, The parameter signal includes at least the first rotational speed signal of the engine, the accelerator position signal and the brake signal. Through the technical scheme of the present invention, the driving speed of the vehicle can be controlled according to the running state of the vehicle, so as to prevent the phenomenon of passive overspeeding during the running of the vehicle, which can effectively reduce the damage to the engine caused by the vehicle's inertia effect, and is beneficial to improve the performance of the vehicle. Driving safety, while reducing the cost of using the vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle control method, a vehicle control system and a vehicle. Background technique [0002] When the car is running at high speed, due to its own inertia, it is prone to passive overspeeding. Especially when the vehicle is going downhill at high speed, if the driver does not operate properly or does not operate in time, it is easy to cause the vehicle to travel faster than the safe speed of the engine. Make the car body anti-drag the engine, causing engine damage. For heavy vehicles such as cargo vehicles and engineering vehicles, the above situation is particularly serious. At present, the solution to the passive speeding of automobiles mainly depends on the manual operation of the driver, which requires the driver to have high driving experience and responsiveness, which makes the operation of the vehicle more difficult and poses certain safety hazards.
