Accident information providing system for automotive vehicle
First Claim
Patent Images
1. An accident information providing system for an automotive vehicle, comprising:
- (a) vehicle position and direction detecting means for detecting current vehicle traveling position and direction;
(b) accident data storing means for storing past traffic accident data under classifications of occurrence locations and causes;
(c) accident data extracting means for extracting past accident data related to roads ahead of a current travel road, determined on the basis of the detected current vehicle traveling position and direction, from said storing means;
(d) drive condition detecting means for detecting vehicle driving conditions;
(e) accident occurrence discriminating means for discriminating a possibility of occurrence of an accident similar to a past accident extracted by said extracting means, on the basis of vehicle driving conditions detected by said drive condition detecting means; and
(f) alarming means for providing an accident-related alarm to a driver when said discriminating means discriminates the possibility of the accident occurrence.

Abstract
The current vehicle position is detected by a position and orientation sensor 101. Past accident data related to roads ahead of the detected position are extracted from an accident data storing unit 109. The vehicle driving conditions (e.g. right/left turn, speed, etc.) are detected by a right/left turn sensor 105 and a speed sensor 102. The possibility of occurrence of an accident similar to the extracted past accident is discriminated on the basis of the detected vehicle driving conditions. An accident alarm is generated through a speech outputting unit 107, for example, if an accident occurrence possibility exists.

9. A method of providing accident information to a driver, comprising the steps of:
-
(a) calculating current vehicle position and current vehicle travel route on the basis of map data and travel position and direction sensor outputs; (b) estimating vehicle travel direction; (c) referring to accident data related to the estimated vehicle travel direction to check whether a frequent accident occurrence point exists ahead of the current vehicle position; (d) if the frequent accident occurrence point exists, referring to the accident data to check a type of past accident which occurs at the frequent accident occurrence point; (e) detecting vehicle driving conditions; (f) checking whether the detected vehicle driving conditions are dangerous by comparing the detected conditions with the checked type of past accident; and (g) if the detected conditions are dangerous, outputting an accident alarm. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
