Abstract

The invention provides an adaptive learning method and device for a zero position of an acceleration pedal and a vehicle. The method comprises the following steps: acquiring a current working state ofthe vehicle; if the current working state of the vehicle indicates that the vehicle accords with a preset condition for adaptively learning the zero position of the acceleration pedal at the present,acquiring a real-time aperture of the acceleration pedal; if the real-time aperture is less than an aperture of a current stored zero position of the acceleration pedal and greater than a preset aperture within a preset time period, setting the zero aperture of the acceleration pedal as the real-time aperture, and updating the stored zero position of the acceleration pedal as the real-time aperture. The phenomenon of learning of an abnormal zero position of the acceleration pedal caused by instant or short-time data abnormality due to electromagnetic interference is effectively avoided.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method, a device and a vehicle for self-adaptive learning of the zero point position of an accelerator pedal. Background technique [0002] Most of the accelerator pedal sensor signals of new energy vehicles are directly collected by the vehicle controller. When the accelerator pedal is disturbed by the external environment, such as floor mats, the accelerator pedal cannot be restored to the mechanical minimum position of the accelerator pedal, or the driver is starting the vehicle. When the accelerator pedal is pressed and the accelerator pedal is not released, in this case, in order to ensure driving safety and enable the vehicle to work normally, a new energy vehicle accelerator pedal opening zero-point adaptive learning method is designed in related technologies. [0003] However, due to factors such as electromagnetic interference, the vehicle may learn an abnormal accelerator p...
