Problems solved by technology

[0003] However, when the accelerator pedal is disturbed by the external environment (such as the floor mat is blocked, the accelerator pedal is stuck, or the driver depresses the accelerator pedal and does not release the accelerator pedal when starting the vehicle), it will cause the accelerator pedal to fail to return to the normal position. The mechanical minimum position of the accelerator pedal, at this time, the power output of the engine will still be output according to the current accelerator pedal opening value, resulting in a much larger accelerator pedal opening than the driver expected, which magnifies the driver's perception of the accelerator pedal. The acceleration requirements of the whole vehicle lead to unsafe driving of the vehicle

Abstract

The invention discloses a zero point position adaptive learning method and device of an accelerator pedal. The method comprises the steps that whether the accelerator pedal meets preset zero point position adaptive learning conditions or not is detected; if it is learned that the accelerator pedal meets the preset zero point position adaptive learning conditions through detection, according to a preset algorithm, the current pedal opening degree value of the accelerator pedal and the currently-stored minimum value of the pedal opening degree of the accelerator pedal are processed to acquire the newest minimum value of the pedal opening degree; and the currently-stored minimum value of the pedal opening degree is updated into the newest minimum value of the pedal opening degree. According to the method, adaptive learning is carried out on the zero point position of the accelerator pedal, the minimum value of the pedal opening degree is adjusted according to the current state of the accelerator pedal, and vehicle traffic safety is protected.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a method and device for adaptively learning the zero position of an accelerator pedal. Background technique [0002] The accelerator pedal is also called the accelerator pedal, and the engine performs power output according to the opening of the accelerator pedal. The larger the opening of the accelerator pedal, the greater the power output of the engine. [0003] However, when the accelerator pedal is disturbed by the external environment (such as the floor mat is blocked, the accelerator pedal is stuck, or the driver depresses the accelerator pedal and does not release the accelerator pedal when starting the vehicle), it will cause the accelerator pedal to fail to return to the normal position. The mechanical minimum position of the accelerator pedal, at this time, the power output of the engine will still be output according to the current accelerator pedal opening valu...
