Title:
HYBRID VEHICLE ACCELERATOR PEDAL POSITION STROKE OUTPUT CALIBRATION METHOD AND HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/193719
Kind Code:
A1
Abstract:
Disclosed are a hybrid vehicle accelerator pedal position stroke output calibration method and a hybrid vehicle. The method comprises: obtaining pedal position voltage parameters outputted by two accelerator pedal position sensors, and when both the pedal position voltage parameters outputted by the two accelerator pedal position sensors are valid, controlling the two accelerator pedal position sensors to perform self-learning separately to obtain accelerator pedal zero point positions; when both the accelerator pedal zero point positions obtained by self-learning by the two accelerator pedal position sensors are valid, mutually verifying the two accelerator pedal position sensors according to the pedal position voltage parameters outputted by the two accelerator pedal position sensors and the accelerator pedal zero point positions; and when the mutual verification of the two accelerator pedal position sensors is passed, calculating accelerator pedal position stroke outputs corresponding to the two accelerator pedal position sensors, calculating an average value, and using the average value as a hybrid vehicle accelerator pedal position stroke output.
