AI Technical Summary

Technical Problem

The voltage signal of the accelerator pedal is susceptible to problems such as zero drift, which causes the accelerator pedal opening obtained by the vehicle analysis to be different from the opening that the driver actually expects, affecting the driving experience and safety.

Method used

When the vehicle is stationary, the system detects whether there are any interfering factors. If there are no interfering factors, it detects and stores the zero-position voltage of the accelerator pedal. When the vehicle is in motion, it calculates the accelerator pedal opening based on the zero-position voltage and theoretical voltage parameters.

Benefits of technology

It improves the accuracy of accelerator pedal opening, ensures the accuracy of the vehicle torque calculation strategy, and enhances the reliability and safety of the vehicle during use.

Abstract

The method, device, vehicle control unit and vehicle provided by the embodiments of the present application calculate the opening degree of the accelerator pedal by detecting whether there is a disturbance factor for the accelerator pedal when the vehicle is in a stationary state, then detecting the zero voltage of the accelerator pedal and storing the zero voltage if there is no disturbance factor for the accelerator pedal, and finally calculating the opening degree of the accelerator pedal according to the zero voltage and the theoretical voltage parameter corresponding to the accelerator pedal when the vehicle is in a moving state. Since the zero voltage of the accelerator pedal is obtained when the vehicle is in a stationary state and there is no disturbance factor for the accelerator pedal, the opening degree of the accelerator pedal is calculated, and therefore the accuracy of the opening degree of the accelerator pedal is improved when the method, device, vehicle control unit and vehicle provided by the embodiments of the present application calculate the opening degree of the accelerator pedal.
