Time service device and time service method of V2X vehicle-mounted unit, vehicle V2X equipment and vehicle

Abstract

The invention relates to a time service device and a time service method of a V2X vehicle-mounted unit, vehicle V2X equipment and a vehicle, and can be applied to the technical field of unmanned / automatic driving vehicles, the time service device comprises a switch switching chip, the switch switching chip is arranged in the V2X vehicle-mounted unit and is connected to a main controller of the V2X vehicle-mounted unit, and the switch switching chip is connected with the main controller of the V2X vehicle-mounted unit. The time service module is used for outputting a time service signal to the main controller; the internal time service module is arranged in the V2X vehicle-mounted unit, is connected to the switch switching chip and is used for outputting an internal time service signal; the external time service module is arranged outside the V2X vehicle-mounted unit, is connected to the switch switching chip through a cable, and is used for outputting an external time service signal; wherein when the switch switching chip is switched to the first state, the switch switching chip takes the internal time service signal as output, and when the switch switching chip is switched to the second state, the switch switching chip takes the external time service signal as output.

Description

technical field [0001] The present disclosure relates to the technical field of unmanned / autonomous driving vehicles, and in particular to a timing device for a V2X vehicle-mounted unit, a timing method, a vehicle V2X device, and a vehicle. Background technique [0002] Currently, in the field of vehicles, Vehicle to Everything communication technology (V2X, Vehicle to Everything) has been widely used in automatic / unmanned vehicle networking and vehicle-road coordination of vehicles. V2X usually includes vehicle-mounted units, roadside units, perception equipment and cloud Platform and other equipment, the form of time service of each equipment through the network during the operation of the vehicle often has a large delay, which will seriously affect the speed of collecting and processing the situation encountered by the vehicle. Generally speaking, the existing V2X The vehicle-mounted unit performs timing through the internal timing module equipped inside. Since the intern...
