Problems solved by technology

For example, the presence of electronic characteristics of the accelerator pedal stroke signal will cause frequent changes in the accelerator pedal stroke signal within a small range, and the frequent changes of the accelerator pedal stroke signal are reflected in frequent changes in the accelerator pedal stroke, which will cause frequent changes in the accelerator opening. Causes the throttle output to be unstable, causing the vehicle to vibrate
As another example, when the vehicle is running on bumpy road conditions, when the driver has no intention to operate the accelerator pedal, the stroke of the accelerator pedal will change frequently within a small range due to the bumps, and the frequent changes of the stroke of the accelerator pedal will cause Frequent changes in the opening, resulting in unstable throttle output, resulting in vehicle jitter
[0004] At present, in order to reduce the frequent changes of the accelerator opening, different filtering methods are usually selected according to different driving conditions, and filtering is performed by limiting the change rate of the accelerator pedal stroke, but this can only ensure that the accelerator opening does not change when the accelerator pedal stroke changes greatly There will be large jumps, but it cannot eliminate the signal jitter caused by electronic characteristics, etc., and the algorithm is complicated, and it cannot effectively reduce the frequent changes of the throttle

Abstract

The embodiment of the disclosure discloses a vehicle accelerator opening degree adjusting method and device, and relates to the technical field of vehicle control. According to the main technical scheme, the vehicle accelerator opening degree adjusting method comprises the steps: determining a reference accelerator opening degree corresponding to a current moment; according to the first corresponding relation, determining a first accelerator opening degree corresponding to the accelerator pedal stroke at the current moment, the first corresponding relation representing the corresponding relation between the accelerator pedal stroke and the accelerator opening degree when the accelerator pedal stroke is gradually increased; according to the second correspondence, determining a second accelerator opening degree corresponding to the accelerator pedal stroke at the current moment, the second corresponding relation representing the corresponding relation between the accelerator pedal strokeand the accelerator opening degree when the accelerator pedal stroke is gradually reduced; determining a target accelerator opening degree corresponding to the current moment based on the comparisonresult of the reference accelerator opening degree, the first accelerator opening degree and the second accelerator opening degree; and adjusting the accelerator opening degree of the vehicle to the target accelerator opening degree.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of vehicle control, in particular to a method and device for adjusting the throttle opening of a vehicle. Background technique [0002] The stroke of the accelerator pedal directly determines the accelerator opening of the vehicle. Frequent changes in the stroke of the accelerator pedal will lead to frequent changes in the accelerator opening of the vehicle power output device, which will make the accelerator output of the vehicle unstable, cause the vehicle to shake, and affect the driving comfort of the driver. . [0003] Frequent changes in accelerator pedal travel are usually caused by the electronic characteristics of the accelerator pedal travel signal or when the vehicle is driven on bumpy road conditions. For example, the presence of electronic characteristics of the accelerator pedal stroke signal will cause frequent changes in the accelerator pedal stroke signal within a...
