1. A system of dynamic wireless transmitting power control using on a vehicle, comprising:
- a receiving unit, for receiving current state information of other driving vehicles around the vehicle;
a state unit, for obtaining current state information of the vehicle;
a storing unit, coupled to the receiving unit and the state unit, for storing current state information of the vehicle and the other driving vehicles;
a transmitting power decision unit, coupled to the storing unit and including a predetermined transmitting power level lookup table, a predetermined upper limit threshold and a predetermined lower limit threshold, wherein the transmitting power decision unit periodically adjusts transmitting power level of the vehicle for generating a reference transmitting power level lookup table, a reference lower limit threshold and a reference lower limit threshold when the vehicle drives for a period of time; and
a transmitting unit, coupled to the state unit and the transmitting power decision unit, for transmitting the current state information of the vehicle to the other driving vehicles.

Abstract
The present disclosure relates to a method and system of dynamic wireless transmitting power control for a vehicle. The system of wireless transmitting power control comprises: a receiving unit, a state unit, a storing unit, a caution unit, a transmitting power decision unit and a transmitting unit. Accordingly, the system of dynamic wireless transmitting power control periodically adjusts a transmitting power level according to the number of driving vehicles so as to adjust transmission radius, decrease transmission interferences and accidents among cars and increase efficiency of wireless frequency usage.
