Abstract
A vehicle driver inputs an alarm signal from an operating unit. A control unit adds a current position of the vehicle detected by a navigation unit to the alarm signal and transmits the alarm signal with the current position from a transmitting and receiving unit to another vehicle. The transmitting and receiving unit receives a signal from another vehicle and supplies the signal to the control unit. The control unit calculates an intervehicular distance from current position data of the other vehicle included in the received signal and current position data of its own vehicle and outputs the alarm signal from speakers only when the intervehicular distance is within a predetermined value.
