SYSTEM AND METHOD FOR INFORMING VEHICLE ACCIDENT USING TELEMATICS DEVICE
First Claim
1. A method of informing a vehicle accident using a telematics device, the method comprising the steps of:
- (a) establishing, by a telematics device installed in a vehicle, an inter-vehicle network between the vehicle and other vehicles around the vehicle through ad-hoc communication;
(b) detecting, by a vehicle sensor installed in the vehicle, an impact and transmitting impact data to the telematics device;
(c) determining, by the telematics device, seriousness of an accident based on the transmitted impact data;
(d) controlling the vehicle according to the determined seriousness of the accident; and
(e) transmitting an accident informing message to telematics devices of the neighboring vehicles connected to the inter-vehicle network.

Abstract
Provided are a system and method for informing a vehicle accident using a telematics device. In an emergency, such as vehicle collision, etc., the system and method propagate information on the accident to vehicles around the accident scene, thereby informing the vehicles of traffic congestion. Since the vehicles continuously inform the same to vehicles behind through ad-hoc communication, a vehicle guided by a telematics device can recognize the traffic congestion ahead, re-search for a path, and thereby make a detour. Therefore, although vehicles behind the accident scene cannot see the occurrence of the accident on a foggy highway, etc., the risk of a chain-reaction crash is reduced. In addition, it is possible to avoid traffic congestion due to an accident in downtown.

10. A system for informing a vehicle accident using a telematics device, the system comprising:
-
a vehicle sensor for detecting an impact to a vehicle and transmitting impact data; a vehicle control device for controlling operation of the vehicle; and the telematics device wiredly or wirelessly connected with the vehicle sensor and the vehicle control device for determining whether an accident of the vehicle has occurred or not and transmitting an accident informing message to vehicles around the vehicle, wherein the telematics device comprises; an input unit for receiving the impact data transmitted from the vehicle sensor; a vehicle control unit for transmitting a vehicle control signal to the vehicle control device; a communication module for establishing an inter-vehicle network through ad-hoc communication with telematics devices installed in the neighboring vehicles; a control unit for analyzing the impact data received from the input unit to see whether an accident has occurred or not and issuing a control instruction to the vehicle control unit; and an output unit for transmitting information relating to the accident according to the instruction from the control unit. - View Dependent Claims (12, 13, 14, 15)
