Abstract

The invention provides a vehicle-mounted time sequence synchronization system which is characterized in that a synchronization time sequence controller 101 uses PTP and gPTP through an Ethernet 103 and a CAN bus 104, and uses PPS signals to perform time sequence synchronization on a sensor laser radar system 105, a millimeter wave radar 106, a camera system 107, an Internet of Vehicles controller108 and a whole vehicle controller 109 in a vehicle through digital synchronization signals 102 so that sensors and controllers of the whole vehicle have high-precision synchronous clock information.By adopting the synchronous time sequence controller 101, accurate time information is provided for data between intelligent sensors 105, 106 and 107 and controllers 108 and 109, and the problems of data synchronization and data fusion between the automobile sensors and the controllers are solved.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a vehicle timing synchronization system.
