Collision Avoidance System
First Claim
1. A collision avoidance system comprising:
- a following vehicle data acquiring unit, provided in a host vehicle, that acquires following vehicle data indicating a relative position and a relative speed, relative to the host vehicle, of a following vehicle traveling behind the host vehicle;
a travel data acquiring unit, provided in the host vehicle, that acquires travel data indicating travel conditions of the host vehicle;
a specific state extraction unit, provided in the host vehicle, that, on a basis of the following vehicle data and the travel data, extracts specific travel data indicating specific travel conditions for the host vehicle under which a possibility of a collision between the host vehicle and the following vehicle is high;
a database unit, provided in the host vehicle, that stores a plurality of pieces of the specific travel data;
a determination unit, provided in the host vehicle, that, on a basis of the travel data acquired by the travel data acquiring unit and the specific travel data stored in the database unit, determines whether or not there is the possibility of the collision between the host vehicle and the following vehicle; and
a warning data output unit, provided in the host vehicle, that outputs warning data to the following vehicle upon the determination unit determining that there is the possibility of the collision.

3. A collision avoidance system comprising:
-
a following vehicle data acquiring unit, provided in a host vehicle, that acquires following vehicle data indicating a relative position and a relative speed, relative to the host vehicle, of a following vehicle traveling behind the host vehicle; a position data acquiring unit, provided in the host vehicle, that acquires position data indicating a position of the host vehicle; a specific state extraction unit, provided in the host vehicle, that, on a basis of the following vehicle data and the position data, extracts specific position data indicating a specific position of the host vehicle where a possibility of the collision between the host vehicle and the following vehicle is high; a database unit, provided in the host vehicle, that stores a plurality of pieces of the specific position data; a determination unit, provided in the host vehicle, that determines whether or not there is the possibility of the collision between the following vehicle and the host vehicle on a basis of the position data acquired by the position data acquiring unit and the specific position data stored in the database unit; and a warning data output unit, provided in the host vehicle, that outputs warning data to the following vehicle upon the determination unit determining that there is the possibility of the collision. - View Dependent Claims (4, 5, 6, 7)
