Control method and control system for activating and deactivating auto vehicle hold function

Abstract

The invention provides a control method and control system for activating and deactivating an auto vehicle hold function, a vehicle, computer equipment, and a computer storage medium. The control method for activating and deactivating the auto vehicle hold function is used for the vehicle, and comprises: acquiring a brake pedal stroke and brake pipeline pressure of the vehicle; calculating brake variables by using the brake pedal stroke and the brake pipeline pressure; judging whether the auto vehicle hold function is activated or not; if the auto vehicle hold function is not activated, determining whether to activate the auto vehicle hold function according to the brake variables; and / or when the auto vehicle hold function is activated, determining whether to deactivate the auto vehicle hold function or not according to the brake variables. By applying the control method for activating and deactivating the auto vehicle hold function, a driver does not need to find a button, activatingand deactivating of the auto vehicle hold (AVH) function of the vehicle is realized by operating a brake pedal, and the judgment result is accurate.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a control method for activating and exiting the automatic holding function, a control system for activating and exiting the automatic holding function, a vehicle, a computer device, and a computer-readable storage medium and another vehicle. Background technique [0002] A known way to activate and exit the AVH (Auto Vehicle Hold) function is to turn on and off the function through the AVH button. However, this mode of operation requires the driver to look down for the button, which is easy to trigger by mistake or forget to trigger. In terms of activation and exit methods, it is not convenient enough. [0003] At the same time, a known way of activating and exiting the AVH function is activated by braking the pedal when a comparison variable of the brake pedal exceeds a predetermined threshold. However, the disadvantage of this method is that The brake pedal is labor...

Problems solved by technology

[0002] A known way to activate and exit the AVH (Auto Vehicle Hold) function is to turn on and off the function through the AVH button. However, this mode of operation requires the driver to look down for the button, which is easy to trigger by mistake or forget to trigger. In terms of activation and exit methods, it is not convenient enough

[0003] At the same time, a known way of activating and exiting the AVH function is activated by braking the pedal when a comparison variable of the brake pedal exceeds a predetermined threshold. However, the disadvantage of this method is that Brake pedal to activate and deactivate this function is laborious and not comfortable enough

[0004] At the same time, it is known that one way to exit the AVH function is through the operation of the shift lever, then the AVH hold mode will be deactivated. However, this method will cause unintended vehicle slippage due to the accidental touch of the shift lever, which will affect safety.
