  • Systems and methods for time synchronization of multiple sensors in a vehicle
    Patent number: 12276947
    Abstract: A method for time synchronization in a vehicle may include transmitting, by a satellite navigation device to a controller and at least one LiDAR device, a UTC and a PPS signal. The satellite navigation device may have a first clock. The method may include synchronizing, by the controller, a second clock of the controller with the first clock of the satellite navigation device based on the PPS signal and the UTC. The method may include synchronizing, by the at least one LiDAR device, a third clock of the at least one LiDAR device with the first clock of the satellite navigation device based on the PPS signal and the UTC. The method may include synchronizing, by at least one camera, a fourth clock of the at least one camera with the second clock of the controller.
