Abstract
A time synchronization method performed by a communication node in a vehicle includes: receiving, from a road side unit (RSU), a first frame including time information of a first domain to which the RSU belongs; setting a time of the vehicle based on a time indicated by the time information of the first domain; and transmitting a second frame including the time information of the vehicle.
Claims14
A communication node performing a time synchronization in a vehicle comprising:
- a controller including a controller processor;
- and
- a memory storing at least one instruction executed by the controller processor, wherein the at least one instruction is configured to:
- receive, from a road side unit (RSU), a first frame including time information of a first domain to which the RSU belongs;
- set a time of the vehicle based on a time indicated by the time information of the first domain;
- and
- transmit a second frame including the time information of the vehicle,
- wherein the second frame comprises priority information including an identifier indicating a type of the first domain, update time information indicating a time at which the time of the vehicle is updated, and position information of the first domain.
A road side unit (RSU) performing a time synchronization of a working clock domain comprising:
- a controller including a controller processor;
- and
- a memory storing at least one instruction executed by the controller processor, wherein the at least one instruction is configured to:
- receive, from a communication node in a vehicle, a synchronization frame including time information of the vehicle;
- and
- set time of the RSU based on time indicated by the time information of the vehicle,
- wherein time indicated by the time information of the vehicle is synchronized with time of a universal time domain,
- wherein the synchronization frame comprises priority information including an identifier indicating a type of the first domain, update time information indicating a time at which the time of the vehicle is updated, and position information of the first domain.
