AI Technical Summary
Technical Problem
In the control system of intelligent vehicles, the timestamps of data collected by different sensors correspond to the clocks of different clock units, resulting in time inconsistencies and causing abnormalities in functions such as autonomous driving.
Method used
By synchronizing the clocks between the first and second controllers, a unified clock is used to add timestamps to the sensor data, ensuring that the clocks of all sensor data are consistent.
Benefits of technology
It achieves clock consistency of sensor data, improves the accuracy of subsequent business processing, and avoids anomalies in autonomous driving functions.

Abstract
This application provides a clock synchronization method and a control system for a control system. The control system includes a first controller and a second controller. The first controller includes a first clock unit and a second clock unit, and the second controller includes a third clock unit. The clock of the first clock unit is different from the clock of the third clock unit, and the clock of the second clock unit is the same as the clock of the third clock unit. The method includes: the first controller and the second controller adding a timestamp to sensor data using a first clock, wherein the first clock is either the clock of the first clock unit or the clock of the third clock unit, ensuring clock consistency of the sensor data, thereby improving the accuracy of subsequent business processing.
