Abstract

The invention provides a pedal signal correction method and device and an automobile, and relates to the field of pedal signal processing of electric automobiles. The pedal signal correction method comprises the following steps: acquiring a pedal signal of a target vehicle; obtaining the maximum accelerator pedal amount in a time period according to the pedal signal of the target vehicle; obtaining a pedal correction coefficient according to the time period and the maximum accelerator pedal amount; and correcting the pedal signal of the target vehicle according to the pedal correction coefficient. According to the embodiment of the invention, the method achieves the correction of the pedal signal of the target vehicle according to the pedal signal of the target vehicle, solves a problem that the vehicle cannot be distinguished when the target vehicle is quickly stepped for a long time and quickly stepped for a short time, and greatly improves the drivability of the vehicle at a full speed and the driving comfort of a user.

Description

technical field [0001] The invention relates to the field of pedal signal processing of an electric vehicle, in particular to a pedal signal correction method, device and vehicle. Background technique [0002] The accelerator pedal is one of the important car components that interact between the driver and the car and express the driver's wishes. The electronic accelerator pedal is equipped with a displacement sensor. When the driver steps on the accelerator pedal, the vehicle controller will collect the change in the opening of the displacement sensor on the pedal and the acceleration, judge the driver's driving intention according to the built-in algorithm, and then report to the whole vehicle. The vehicle controller sends corresponding control signals to control the power output of the electric vehicle motor. Therefore, the signal of the accelerator pedal is very important for the drivability and ride comfort of the vehicle. An appropriate accelerator pedal signal allow...
