Timing correction method and corresponding controller, vehicle, equipment and medium

Abstract

The invention provides a method for timing correction of a controller, a corresponding controller, a vehicle, equipment and a medium. The method comprises the following steps of a main control unit of the controller acquiring a first standard time at the moment and sending a current sleep timing command indicating a current sleep timing period to a real-time clock unit of the controller when the controller is about to sleep; when the current awakening signal received from the real-time clock unit is awakened, acquiring second standard time at the moment; determining a current correction amount for timing correction based on a time difference between the second standard time and the first standard time and the current sleep timing period; and determining a subsequent sleep timing period indicated by the subsequent sleep timing command sent to the real-time clock unit by using the current correction value. By utilizing the method, a timing error of the real-time clock unit can be dynamically compensated in a self-learning manner, so the real-time clock unit performs sleep timing awakening on the controller in a more accurate timing manner, and the feeling and the experience of a user can be improved.

Description

technical field [0001] The present invention relates to the technical field of timing and timing, and more specifically, relates to a method for timing correction by a controller, a controller suitable for timing correction, corresponding vehicles, computer equipment, and computer-readable storage media . Background technique [0002] A real-time clock (Real-Time Clock, RTC) unit is widely used to provide a time reference for electronic systems, usually in the form of an integrated circuit chip. At present, most RTC chips use a crystal oscillator as a clock source, and its timing error mainly comes from the frequency error of the crystal oscillator. Due to the inconsistency of the crystal oscillator, the timing error of the RTC chip has a large dispersion. When the RTC chip is installed and configured inside the controller to wake up the controller regularly, due to the low power consumption of the RTC chip, the timing error and discrete problems of the RTC chip are more p...

AI Technical Summary

Problems solved by technology

When the RTC chip is installed and configured inside the controller to wake up the controller regularly, due to the low power consumption of the RTC chip, the timing error and discrete problems of the RTC chip are more prominent, and the timing cannot be calibrated by fixed parameters. Correction
