The present invention relates to an accelerator pedal zero position self-adaptive learning method, device and automobile. The method comprises the following steps: obtaining the current voltage value corresponding to the current pedal opening value of the accelerator pedal in real time, and comparing the current voltage value with the currently stored minimum value. The voltage value is differenced to obtain a voltage difference value, wherein the currently stored minimum voltage value is the voltage storage value corresponding to the current pedal opening minimum value; according to the calculated voltage difference value, the voltage is calculated in the preset fuzzy rule Value adjustment step; the currently stored minimum voltage value, adjust the step according to the voltage value, and update it to the current voltage value in real time. The zero position adaptive learning method of the accelerator pedal proposed by the present invention can adjust the minimum value of the accelerator pedal opening with a suitable step according to the actual situation, thereby ensuring safety and improving user experience.
Description
technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an accelerator pedal zero position self-adaptive learning method, device and automobile. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, people's living standards have also been significantly improved. Especially in recent years, people's way of travel has become more convenient and efficient. As the most commonly used means of transportation, automobiles play an important role in transportation. [0003] For automobiles, the electronic throttle control system is a vital component. The electronic throttle control system is mainly composed of electronic throttle body, accelerator pedal and electronic controller. Specifically, the ECU calculates the desired throttle opening according to signals from the accelerator pedal position sensor and other related sensors, and outputs a control signal to contro...
