Method and device for zero-position correction of push rod of electronic brake booster

Abstract

This application relates to a method and apparatus for zero-position correction of the pushrod in an electronic brake booster. The method includes: detecting the current operating condition of the vehicle's electronic brake booster; when the current operating condition is detected to be a pushrod stuck condition, identifying the actual duty cycle of the pushrod at the current moment, and determining the pushrod zero position of the electronic brake booster based on the actual duty cycle; and executing a preset correction action based on the pushrod zero position to correct at least one of the vehicle's pedal opening, pushrod travel, and pedal depressing signal. The embodiments of this application can use the actual duty cycle of the pushrod at the time of pushrod sticking as the new pushrod zero position, thereby correcting parameters such as pedal opening, pushrod travel, and pedal depressing signal, achieving the purpose of pushrod zero-position correction, improving vehicle intelligence, enhancing the user's driving experience, and effectively ensuring the vehicle's overall safety protection level.
