Method for Early Warning of Vehicle Collision, On-Board Terminal and Server

A method for early earning of vehicle collision applied to a server, the method comprising:

• acquiring vehicle data transmitted by a plurality of on-board terminals, the vehicle data including positioning information of vehicles, driving speed of vehicles, and orientation information of vehicles;
• determining an early warning range of a vehicle to which each of the plurality of on-board terminals belongs based on the vehicle data;
• determining whether there are mutually intersected early warning ranges in early warning ranges of the plurality of on-board terminals;
• transmitting a third early warning information to an on-board terminal within the mutually intersected early warning ranges when there are mutually intersected early warning ranges.

An on-board terminal comprising:

• a first processor, a plurality of second processors, and a wireless transceiver, wherein each second processor is connected to a sensor, and wherein
• the wireless transceiver is configured to communicate with other on-board terminals;
• each second processor is configured to transmit first distance-sensing data detected by a sensor connected to itself to the first processor;
• the first processor is configured to determine whether there is an obstacle within an early warning range of the on-board terminal based on the received first distance-sensing data;
• acquire, through the wireless transceiver, distance-sensing data transmitted by on-board terminals of other vehicles as second distance-sensing data when it is determined that there is an obstacle;
• determine whether the obstacle is a vehicle based on a matching result of the first distance-sensing data and the second distance-sensing data;
• output a first early warning information when it is determined that the obstacle is a vehicle.
