METHOD FOR TIME SYNCHRONIZATION OF A PLURALITY OF AUXILIARY DEVICES OF AUTONOMOUS VEHICLE, VEHICLE, COMPUTER DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2021/232260

A1

A method for time synchronization of a plurality of auxiliary devices of an autonomous vehicle, the vehicle, a computer device, and a computer readable storage medium. The method comprises: determining one of the plurality of auxiliary devices as a main auxiliary device, and taking a clock of the main auxiliary device as a main clock (202); controlling, by a programmable logic device, to transmit a PTP protocol message between the main auxiliary device and other auxiliary devices via a network (204); calculating a time deviation between the clocks of the other auxiliary devices and the main clock of the main auxiliary device on the basis of the transmission of the PTP protocol message (206); and adjusting the clocks of the other auxiliary devices on the basis of the time deviation so that the clocks of the other auxiliary devices are synchronized with the main clock (208).
