Abstract

To provide a vehicular braking control device which, at the time of a collision of a host vehicle, can apply a braking force to the host vehicle while reducing the potential for a rear-end collision from a following vehicle.

A vehicular braking control device equipped with collision detecting means that detects a collision of a host vehicle and braking force applying means that applies a braking force to the host vehicle when a collision of the host vehicle has been detected includes: following vehicle running state detecting means that detects whether or not there is, and the running state of, a following vehicle; following vehicle braking force detecting means that detects whether or not the following vehicle has a braking control device on board; and avoidance determining means which, in a case where there is the following vehicle at the time of a collision of the host vehicle, discriminates whether or not the following vehicle can avoid the host vehicle on the basis of information detected by the following vehicle running state detecting means and the following vehicle braking force detecting means, wherein the braking force applying means varies the braking force it applies to the host vehicle on the basis of the result of the determination by the avoidance determining means.

Claims

1. A vehicular braking control device equipped with collision detecting means that detects a collision of a host vehicle and braking force applying means that applies a braking force to the host vehicle when a collision of the host vehicle has been detected, the vehicular braking control device comprising:

following vehicle running state detecting means that detects whether or not there is a following vehicle and the running state thereof;

following vehicle braking force detecting means that detects whether or not the following vehicle has a braking control device on board; and

avoidance determining means which, in a case where there is the following vehicle at the time of a collision of the host vehicle, discriminates whether or not the following vehicle can avoid the host vehicle on the basis of information detected by the following vehicle running state detecting means and the following vehicle braking force detecting means,

wherein the braking force applying means varies the braking force it applies to the host vehicle on the basis of the result of the determination by the avoidance determining means.

2. The vehicular braking control device according to claim 1, wherein in a case where it is not discriminated that the following vehicle can avoid the host vehicle, the braking force applying means applies the braking force in such a way as to guide the host vehicle to a position where the host vehicle will not impede the traveling direction of the following vehicle.

3. The vehicular braking control device according to claim 1, further comprising road shoulder information detecting means that detects whether or not there is a road shoulder in the traveling direction of the host vehicle at the time of a collision of the host vehicle, wherein in a case where it is not discriminated that the following vehicle can avoid the host vehicle, when the road shoulder has been detected, the braking force applying means applies the braking force in such a way as to guide the host vehicle in the road shoulder direction.

4. The vehicular braking control device according to claim 1, further comprising obstacle detecting means that detects whether or not there is an obstacle in the traveling direction of the host vehicle at the time of a collision of the host vehicle, wherein in a case where it has been discriminated that the following vehicle can avoid the host vehicle, when an obstacle has been detected in front of the host vehicle, the braking force applying means applies the braking force in such a way as to promptly stop the host vehicle.

5. The vehicular braking control device according to claim 4, wherein in a case where it has been discriminated that the following vehicle can avoid the host vehicle, when an obstacle has not been detected in front of the host vehicle and the road shoulder has been detected, the braking force applying means applies the braking force in such a way as to guide the host vehicle in the road shoulder direction.

6. The vehicular braking control device according to claim 1, wherein in a case where it has been discriminated that the following vehicle can avoid the host vehicle, the braking force applying means applies the braking force in such a way as to promptly stop the host vehicle.

7. The vehicular braking control device according to claim 1, wherein the avoidance determining means detects whether or not there is an inter-vehicle distance in which the following vehicle can stop without colliding into the host vehicle when the host vehicle has been promptly stopped by the braking force applying means.
