Collision Avoidance System and Collision Avoidance Method
First Claim
1. A collision avoidance system comprising:
- a rear detection device arranged in a host vehicle and capable of detecting an object directly behind the host vehicle, an object to rear-right of the host vehicle, and an object to rear-left of the host vehicle in a non-contact manner;
a computation processing unit that, on a basis of a detection result from the rear detection device, outputs presence/absence of a possibility of a collision between the host vehicle and a first following vehicle approaching the host vehicle from directly behind, presence/absence of a possibility of a collision between the host vehicle and a second following vehicle approaching the host vehicle from the rear-right, and presence/absence of a possibility of a collision between the host vehicle and a third following vehicle approaching the host vehicle from the rear-left; and
a warning device that, on a basis of an output result from the computation processing unit, generates a first warning when there is the possibility of a collision with the first following vehicle, generates a second warning when there is the possibility of a collision with the second following vehicle, and generates a third warning when there is the possibility of a collision with the third following vehicle.

Abstract
A collision avoidance system is provided with: a rear detection device arranged in a host vehicle and capable of detecting an object directly behind the host vehicle, an object to the rear-right of the host vehicle, and an object to the rear-left of the host vehicle in a non-contact manner. A computation processing unit outputs, on the basis of a detection result from the rear detection device, the presence/absence of the possibility of a collision between the host vehicle and: a first following vehicle approaching the host vehicle from directly behind, a second following vehicle approaching the host vehicle from the rear-right, and a third following vehicle approaching the host vehicle from the rear-left. A warning device generates warnings when there is the possibility of a collision with the first, second or third following vehicles.

19. A collision avoidance method comprising the steps of:
-
detecting an object directly behind a host vehicle, an object to rear-right of the host vehicle, and an object to rear-left of the host vehicle in a non-contact manner using a rear detection device arranged in a host vehicle; determining, on the basis of a detection result from the rear detection device, presence/absence of a possibility of a collision with a first following vehicle approaching the host vehicle from directly behind, presence/absence of a possibility of a collision with a second following vehicle approaching the host vehicle from the rear-right, and presence/absence of a possibility of a collision with a third following vehicle approaching the host vehicle from the rear-left; and generating a first warning when there is the possibility of a collision with the first following vehicle, generating a second warning when there is the possibility of a collision with the second following vehicle, and generating a third warning when there is the possibility of a collision with the third following vehicle, on a basis of a result of the determination, using a warning device arranged in the host vehicle.
