Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] This embodiment provides an accelerator pedal self-adaptive method, which can be applied to a vehicle-mounted controller. The vehicle-mounted controller performs a reasonable checksum on the voltage deviation value by judging whether the vehicle state data satisfies the pedal self-adaptation condition. Perform a reasonable check on the real-time offset. In the process of adjusting the stroke opening of the accelerator pedal, after multiple checks...

Abstract

The invention discloses an accelerator pedal self-adaption method, a vehicle-mounted controller, an automobile and a storage medium. The accelerator pedal self-adaption method comprises the steps that vehicle state data are obtained, and whether the vehicle state data meet pedal self-adaption conditions or not is judged; if the vehicle state data meets the pedal self-adaption condition, the actually-measured voltage value of the accelerator pedal at the current position is collected in real time; performing deviation calculation on the actually measured voltage value and the calibrated voltage value to obtain a voltage deviation value, and performing reasonable verification on the voltage deviation value to obtain a voltage deviation verification result; if the voltage deviation verification result is reasonable, carrying out reasonable verification on the real-time offset, and obtaining an offset verification result; if the offset verification result is reasonable, a target voltage value is obtained according to the actually measured voltage value and the target offset, and the accelerator pedal stroke opening degree is determined according to the target voltage value. According to the technical scheme, the travel opening degree of the accelerator pedal is reliable and authentic, and the driving safety of a driver is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an accelerator pedal adaptive method, a vehicle controller, a vehicle and a storage medium. Background technique [0002] In the control of new energy vehicles, the accelerator pedal stroke opening is an important input of the vehicle torque, which directly reflects the driver's acceleration demand for the vehicle, that is, whether the accelerator pedal stroke opening accurately reflects the driver's vehicle acceleration demand. It has a significant impact on the safe operation of the vehicle. At present, the sensor voltage of the accelerator pedal of new energy vehicles is mostly collected directly by the on-board controller. When the initial zero position of the accelerator pedal is deviated, or as the electronic components of the accelerator pedal age, the sensor voltage corresponding to the initial zero position of the accelerator pedal will shift, resulting in the se...
