Abstract
A communication mode selection method includes transmitting, in a first communication mode, a vehicle-to-everything (V2X) service between a leading vehicle and a following vehicle that are in a vehicle platoon, obtaining, signal quality of the first communication mode, when the signal quality of the first communication mode meets a first preset condition, sending, a configuration instruction to the following vehicle, where the configuration instruction is used to instruct the following vehicle to communicate with the leading vehicle in a second communication mode, where the second communication mode is a communication mode in which a network device performs forwarding.
Claims20
A communication mode selection method, implemented by a leading vehicle, wherein the communication mode selection method comprises:
- transmitting, in a first communication mode, a vehicle-to-everything (V2X) service between the leading vehicle and a following vehicle that are in a vehicle platoon, wherein the first communication mode is a direct communication mode;
- obtaining a signal quality of the first communication mode, wherein the signal quality is signal reliability;
- obtaining a signal reliability of communication between the following vehicle and the leading vehicle in the first communication mode and in a time window;
- and
- sending a configuration instruction to the following vehicle when the signal quality of the first communication mode meets a preset condition,
- wherein the configuration instruction instructs the following vehicle to enable a second communication mode to communicate with the leading vehicle,
- wherein the second communication mode is for network device forwarding, and
- wherein the preset condition identifies the signal reliability in the time window is less than a threshold.
A communication mode selection method, implemented by a following vehicle, wherein the communication mode selection method comprises:
- sending vehicle-to-everything (V2X) capability information of the following vehicle to a leading vehicle, wherein the V2X capability information indicates a communication mode supported by the following vehicle;
- obtaining a signal quality of a first communication mode;
