WIRELESS COMMUNICATION APPARATUS FOR VEHICLE AND WIRELESS COMMUNICATION METHOD BETWEEN RUNNING VEHICLES USING THE SAME
First Claim
1. A wireless communication method between running vehicles, comprising:
- a step of receiving and collecting, by a wireless communication unit of a target vehicle, running information of a partner vehicle by communicating with a wireless communication unit of the partner vehicle;
a step of estimating, by a calculation unit of the target vehicle 100, a current distance from the partner vehicle 200 through the collected running information of the partner vehicle;
a step of setting, by a control unit of the target vehicle, a transmission rate of communication data in correspondence with the current distance from the partner vehicle;
a step of monitoring, by the calculation unit of the target vehicle, a change in the distance from the partner vehicle; and
a step of changing, by the control unit of the target vehicle, the transmission rate of the communication data in correspondence with the change in the distance from the partner vehicle.
