1. An inter-vehicle communication device mounted on a vehicle comprising:
- a transmission device for transmitting information about the vehicle to other vehicles around the vehicle with a predetermined transmission period; and
a transmission control device for controlling the transmission device, wherein the inter-vehicle communication device further comprises;
a speed detection device for detecting a speed of the vehicle;
a transmission period calculation device for calculating the transmission period in such a manner that the transmission period is shorter as the speed of the vehicle becomes larger;
a warning element state detection device for detecting an operation state of a warning element, which is mounted on the vehicle in order to inform a person around the vehicle of a state of the vehicle and existence of the vehicle; and
a speed determination device for determining whether the speed of the vehicle detected by the speed detection device is larger than a predetermined speed,wherein the transmission control device controls the transmission device to transmit the information with a period shorter than the transmission period calculated by the transmission period calculation device according to the speed of the vehicle when the speed determination device determines that the speed of the vehicle detected by the speed detection device is equal to or smaller than the predetermined speed, and it is determined on the basis of a detection result of the warning element state detection device that the warning element functions.

Abstract
An inter-vehicle communication device for a vehicle includes: a transmission element for transmitting information about the vehicle to other vehicles with a predetermined period; a transmission controller for controlling the transmission element; and a detector for detecting a state of an indicator in the vehicle. The indicator informs a person around the vehicle about a state and existence of the vehicle, and the transmission controller controls the transmission element to transmit the information with a period shorter than the predetermined period when the detector detects that the indicator functions.
