Accelerator pedal signal calibration method and device, medium, vehicle-mounted device and vehicle

The invention relates to an accelerator pedal signal calibration method and device, a medium, a vehicle-mounted device and a vehicle. The accelerator pedal signal calibration method comprises the following steps: acquiring power supply voltage of a power supply to an accelerator pedal and linear voltage synchronously acquired by an accelerator pedal sensor; obtaining theoretical voltage corresponding to the power supply voltage; determining a target voltage based on the power supply voltage, the theoretical voltage and the linear voltage; wherein the ratio of the power supply voltage to the theoretical voltage is equal to the ratio of the linear voltage to the target voltage. According to the technical scheme, the linear voltage can be calibrated, namely, the target voltage is determined, the accuracy of accelerator pedal signal collection can be improved without using a high-performance chip and a high-requirement vehicle wiring material, then the accuracy of oil supply control of a vehicle engine is improve
