Claim:
1. An apparatus for warning communications between vehicles, comprising: a route estimating unit configured for estimating a future position of a vehicle using a current speed and a current position of the vehicle; a WAVE data communication unit configured for receiving WAVE messages broadcast from nearby vehicles; a control unit configured for estimating a risk of an accident with one or more nearby vehicles using the future position of the vehicle and WAVE messages from nearby vehicles; and an alarm output unit configured for warning the risk of an accident with one or more nearby vehicles, wherein when a WAVE message received from a first nearby vehicle comprises a loss-of-control status indicating that the first nearby vehicle has lost its control, the control unit is configured to estimate the risk of an accident between the vehicle and the first nearby vehicle using the future position of the vehicle estimated by the route estimating unit and further using an estimated future position at a future time of the first nearby vehicle contained in the WAVE message, wherein when the control unit's estimated risk of an accident is at a predetermined level or higher, the alarm output unit is configured to output a warning about the risk of an accident for a driver of the vehicle, wherein when a subsequent WAVE message received from the first nearby vehicle comprises the loss-of-control status indicating that the first nearby vehicle has gained its control while the alarm output unit is outputting the warning about the risk of an accident, the control unit is configured to cause the alarm output unit to stop outputting the warning.
