Vehicle control method and device, storage medium and vehicle

Abstract

The invention relates to a vehicle control method and device, a storage medium and a vehicle. The pressure of a brake master cylinder and the opening degree of an accelerator pedal are obtained; when the pressure of the brake master cylinder is greater than a first preset pressure threshold value, the opening degree of the accelerator pedal is not less than a first preset opening degree threshold value, and the moment when the pressure of the brake master cylinder is greater than the first preset pressure threshold value is earlier than the moment when the opening degree of the accelerator pedal is not less than the first preset opening degree threshold value; the vehicle is controlled to enter an activated state of an ejection starting function; and an engine of the vehicle is controlled to output the target torque under the condition that the vehicle is in the activated state. Thus, a driver can simultaneously operate a brake pedal and an accelerator pedal to enable the vehicle to enter an activated state of an ejection starting function before starting, that is, torque output can be provided according to the state of the accelerator pedal when the vehicle is in a brake state, so that the vehicle can be quickly started with large power, the acceleration time is reduced, and catapult starting is achieved.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a vehicle control method, device, storage medium and vehicle. Background technique [0002] In existing vehicles, the brake pedal and the accelerator pedal are the core components of the driver's driving intention recognition. The brake pedal can be depressed by one side of the foot to brake the vehicle, and the pedal can be depressed by one side of the foot. Press the accelerator pedal to start and so on. Generally speaking, when the brake pedal is depressed and after the brake pedal is fully depressed, the torque output of the engine will be stopped. Only in the process of slowly releasing the brake pedal, the torque of the engine will It will start to load slowly, and when the brake pedal is fully released, the vehicle will start to enter creep mode and start to drive slowly. After stepping on the accelerator, the vehicle recognizes the driver's acceleration intention a...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the brake pedal and the accelerator pedal are two independent parts, which play the role of braking and acceleration respectively, and the two are designed on the same side, and the driver can only step on one at the same time, that is, the driver In the process of braking with the brake pedal, it is not possible to input the driving intention through the accelerator pedal, and it is not possible to brake at the same time during the process of accelerating with the accelerator pedal.

Moreover, when the brake pedal is depressed, the engine output torque will be prohibited. If you want to resume driving after stopping the brake, you can only enter the creep mode first, and then control the engine to slowly increase the output torque through the accelerator pedal to increase the speed of the vehicle. , the vehicle speed increases slowly
