Abstract

In a vehicle driving support apparatus, a cruise control unit determines a possibility of a collision of a subject vehicle 1 and an obstacle. If it is determined that there is a high possibility of a collision of the subject vehicle and the obstacle, the cruise control unit previously sets a braking force for preventing a collision against the obstacle and outputs a signal regarding the set braking force to an automatic braking control to generate deceleration. If a steering operation by a driver is detected at this time, the braking force to be generated is adjusted to a lower value.

Claims

1. A vehicle driving support apparatus comprising:

a front obstacle information detecting unit for detecting information on a front obstacle;

a collision possibility determining unit for determining a possibility of a collision of a subject vehicle and the front obstacle;

a collision prevention control unit for setting previously and generating a braking force for preventing a collision against the front obstacle; and

a braking force adjusting unit for adjusting the braking force to be generated by the collision prevention control unit to a lower value when a steering operation by a driver is detected.

2. The vehicle driving support apparatus according to claim 1, wherein the braking force adjusting unit prohibits adjusting the braking force to a lower value if the possibility of a collision against the front obstacle is higher than a predetermined level.

3. The vehicle driving support apparatus according to claim 2, wherein the collision possibility determining unit determines that the possibility of a collision against the front obstacle is higher than the predetermined level when a lapping rate between the subject vehicle and the front obstacle exceeds a predetermined threshold.

4. The vehicle driving support apparatus according to claim 1, wherein the braking force for preventing a collision against the front obstacle is variably set by the collision prevention control unit based on traveling environment of the subject vehicle.

5. The vehicle driving support apparatus according to claim 2, wherein the braking force for preventing a collision against the front obstacle is variably set by the collision prevention control unit based on traveling environment of the subject vehicle.

6. The vehicle driving support apparatus according to claim 3, wherein the braking force for preventing a collision against the front obstacle is variably set by the collision prevention control unit based on traveling environment of the subject vehicle.

7. The vehicle driving support apparatus according to claim 4, wherein the braking force for preventing a collision against the front obstacle is set higher by the collision prevention control unit when the subject vehicle is travelling on a road with a higher road friction coefficient.

8. The vehicle driving support apparatus according to claim 5, wherein the braking force for preventing a collision against the front obstacle is set higher by the collision prevention control unit when the subject vehicle is travelling on a road with a higher road friction coefficient.

9. The vehicle driving support apparatus according to claim 6, wherein the braking force for preventing a collision against the front obstacle is set higher by the collision prevention control unit when the subject vehicle is travelling on a road with a higher road friction coefficient.
