Apparatus and method for warning loss of control of a vehicle using vehicle-to-vehicle communications
First 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.

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.

4. A method for warning using communications between vehicles, comprising:
-
estimating, using a route estimating unit, a future position of a vehicle using a current speed and a current position of the vehicle; receiving, using a WAVE data communication unit, WAVE messages broadcast from nearby vehicles; estimating, using a control unit, 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 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 control unit is configured to cause an alarm output unit 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. - View Dependent Claims (5, 6, 7)
