Patent ID: 7414541

Claim:
A vehicle communication device comprising: a plurality of transmitting and receiving sensors that respectively are installed in the front and back side and the left and right side of a vehicle so as to transmit and receive driving information to and from neighboring vehicles; a left/right rotation signal detecting section that detects a left or right rotation signal generated by a driver of the vehicle; a wheel angle detecting section that detects a wheel rotation angle of the vehicle; a vehicle speed detecting section that detects the speed of the vehicle; a central control section that transmits the driving information of the vehicle, including lane change or increase and reduction in speed, to the neighboring vehicle through the corresponding transmitting and receiving sensor, when a left or right rotation signal is detected through the left/right rotation signal detecting section, the wheel rotation angle of the vehicle detected through the wheel angle detecting section changes more than a predetermined angle, or the speed of the vehicle detected through the vehicle speed detecting section changes more than or less than predetermined speed, and that outputs positional information of the neighboring vehicle with an alarm signal, when receiving the lane change or speed change information of the neighboring vehicle from an arbitrary transmitting and receiving sensor; and a driver information section that, when receiving the positional information of the neighboring vehicle with the alarm signal from the central control section, inform a driver of the information.
