APPARATUS AND METHOD FOR WARNING LOSS OF CONTROL OF A VEHICLE USING VEHICLE-TO-VEHICLE COMMUNICATIONS
First Claim
1. An apparatus for warning loss of control of a vehicle using communications between vehicles, comprising:
- a speed detecting unit for detecting a travel speed of an own vehicle;
a position detecting unit for detecting a current position and a travel direction of the own vehicle;
a route estimating unit for estimating a future position of the own vehicle after a predetermined time period using the current speed and the position information;
a WAVE message generating unit for generating a WAVE message including the future position information of the own vehicle after the predetermined time period;
a WAVE data communicating unit for broadcasting the WAVE message to a surrounding vehicle and an infrastructure periodically, and receiving the WAVE message broadcast from the surrounding vehicle and the infrastructure;
a control unit for sensing accident risk using the future position information of the own vehicle and the future position information of the surrounding vehicle, when the surrounding vehicle is in loss of control; and
a guide and alarm output unit for warning the accident risk by an audible means, a visible means, and a vibrating means in combination under the control of the control unit in advance, or providing behavior guides to a driver to prevent the traffic accident in advance.

Abstract
An apparatus for warning loss of control of a vehicle using communications between vehicles may include: a speed detecting unit for detecting a speed of a vehicle; a position detecting unit for detecting a current position and a travel direction of the vehicle; a route estimating unit for estimating a future position of the vehicle after a time period using the current speed and the position information; a WAVE message generating unit for generating a WAVE message comprising the future position information of the vehicle; a WAVE data communicating unit for broadcasting the WAVE message to a surrounding vehicle and an infrastructure periodically, and receiving WAVE message broadcast from the surrounding vehicle and the infrastructure; and a control unit for sensing accident risk using the future position information of the vehicle and the future position information of the surrounding vehicle, when the surrounding vehicle is in loss of control.

6. A method for warning loss of control of a vehicle using communications between vehicles, comprising:
-
sensing, by a control unit, at least one vehicle abnormal signals generated by actuating a function of the vehicle according to an operating maneuver performed by a driver in an emergency situation which is encountered during travelling of the own vehicle; determining, by the control unit, whether a current speed of the vehicle is above a predefined threshold at the same time when the vehicle abnormal signal is sensed, or within a predefined time period; further sensing, by the control unit, vehicle abnormal status information, when the current speed of the vehicle is above the threshold while the vehicle abnormal signal is sensed; determining, by the control unit, that the vehicle is in loss of control status, when the current speed of the vehicle is above the threshold while the vehicle abnormal signal is sensed, and also the vehicle abnormal status information is sensed; generating, by the control unit, a WAVE message where the loss-of-control status is recorded in a particular field for recording event information in the WAVE message via a WAVE message generating unit; and broadcasting, by the control unit, the WAVE message to the surrounding through the WAVE data communicating unit. - View Dependent Claims (7)

8. A method for warning loss of control of a vehicle using communications between vehicles, comprising:
-
receiving, under the control of a control unit, a WAVE message broadcast from a surrounding vehicle through a WAVE data communicating unit; analyzing, by the control unit, the WAVE message and, when the WAVE message contains status information pointing to the loss of control, calculating a relative position between an own vehicle and the surrounding vehicle using the status information contained in the WAVE message; determining, by the control unit, whether a position of the own vehicle is in a range of possible accident risk with the surrounding vehicle using the relative position between the own vehicle and the surrounding vehicle; and when the own vehicle is positioned in the range of possible accident risk, detecting, by the control unit, a travel speed of the own vehicle, and outputting a guide and an alarm to prevent an accident via a guide and alarm output unit assuming that there is a possible risk that the accident will take place when the travel speed is above a predefined threshold. - View Dependent Claims (9, 10)
