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 th

Example Embodiment
[0032] An exemplary embodiment of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown, it is understood that the disclosure can be implemented in various forms without limitation. Instead, these embodiments are provided to be more thoroughly understood to disclose the present disclosure, and can communicate the scope of the scope of the present disclosure to those skilled in the art.
[0033] A first aspect, the present embodiment provides a method for adjusting the throttle opening of a vehicle disclosed, such as figure 1 As shown, the method mainly includes:
[0034] 101, determining a reference accelerator opening degree corresponding to the current time.
[0035] In practical applications, an accelerator for increasing the stability of the vehicle output, it is necessary to periodically vehicle accelerator opening degree is adjusted where necessary to a...

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...
