Vehicle power control method and system, computer readable storage medium and vehicle

Abstract

The invention discloses a vehicle power control method and system, a computer readable storage medium and a vehicle. The vehicle power control method comprises the steps that the accelerator pedal opening is obtained and whether an accelerator pedal is stepped on or not is judged; on-off information of a brake pedal is obtained and whether the brake pedal is stepped on is analyzed; a pressure value of a brake master cylinder is obtained; vehicle demand power is explained according to the opening of the accelerator pedal in response to the accelerator pedal not being stepped on; the vehicle demand power is explained according to the opening of the accelerator pedal in response to the accelerator pedal being stepped on and the brake pedal not being stepped on; in response to the acceleratorpedal and the brake pedal both being stepped on, the pressure value of the brake master cylinder is more than a pressure threshold value Prs1, the time of the accelerator pedal and the brake pedal both being stepped on is more than or equal to a threshold value T1, the whole vehicle demand power is analyzed according to the pressure value of the brake master cylinder and the opening of the accelerator pedal, if not, the vehicle demand power is explained according to the opening of the accelerator pedal, but a power threshold value Pwr3 cannot be exceeded. The vehicle power control method guarantees the safety, and has a good driving experience.

Description

technical field [0001] The invention belongs to the technical field of vehicle power control, and in particular relates to a method, system, computer-readable storage medium and vehicle for vehicle power control. Background technique [0002] At present, the vast majority of automobiles on the market are equipped with independent accelerator pedals and brake pedals, which are two key components for the driver to control the car, and are directly related to the safety of the driver, pedestrians and vehicles. [0003] When the user is driving, it is difficult to avoid the situation that the accelerator pedal and the brake pedal are stepped on at the same time. The situation that both pedals are stepped on may be caused by the driver's subjective operation, or it may be caused by a system failure of the vehicle itself. In order to ensure that the vehicle can be braked when both pedals are depressed, most vehicle control systems simply cut off the power output or open the accele...

AI Technical Summary

Problems solved by technology

[0004] (1) The shoes worn by the user are relatively wide, and when the foot moves from the brake pedal to the accelerator pedal, the accelerator pedal and the brake pedal will be pressed at the same time in a short period of time. The opening is interpreted as 0%) will cause obvious shaking of the whole vehicle, which is obviously not the effect expected by the user

[0005] (2) The brake switch wiring harness is abnormal, causing the system to misjudge that the brake switch has been stepped on

In this case, if the power is cut off or the accelerator pedal opening is interpreted as 0%, this will cause the vehicle to have no power output and therefore the vehicle cannot move, even from the middle lane to the side of the road or a safer area.

[0006] (3) Some drivers have the habit of depressing the brake pedal and the accelerator pedal at the same time to start on a slope. In this case, if the power is cut off or the accelerator pedal opening is interpreted as 0%, this will cause the vehicle to have no power output and cannot complete vehicle launch
