Vehicle driving support control apparatus
First Claim
1. A vehicle driving support control apparatus comprising:
- a first vehicle information detecting unit that acquires vehicle information of a vehicle around an own vehicle by inter-vehicle communication within an inter-vehicle communication first distance;
a second vehicle information detecting unit that acquires vehicle information, on the basis of images captured by an imaging device in the travelling direction of the own vehicle, as to a vehicle at least up to a second distance ahead of the own vehicle, the second distance being shorter than the first distance; and
a driving support control unit that, when the second vehicle information detecting unit detects a vehicle ahead, acquires, by the second vehicle information detecting unit, vehicle information of the detected vehicle ahead and performs a driving support control for the own vehicle based upon the vehicle information from the second vehicle information detecting unit, andthat, the driving support control unit, upon determining that the second vehicle information detecting unit does not detect a vehicle ahead;
a) initiates reliance on the first vehicle information detecting unit to the exclusion of the second vehicle information detecting unit relative to vehicle ahead extraction for performing driving support control for the own vehicle relative to the extracted vehicle ahead when the inter-vehicle communication first distance is satisfied and a threshold condition is satisfied, andb) acquires, by the first vehicle information detecting unit, vehicle information of a vehicle more than a threshold value ahead, the threshold value being selected from either one of a distance to a start point of a curve ahead or the second distance according to the configuration of the driving lane on which the own vehicle travels and the configuration of the road ahead, and when the vehicle ahead is present a distance more than the threshold value, the threshold condition is deemed satisfied and the driving support control unit performs driving support control for the own vehicle based upon the vehicle information from the first vehicle information detecting unit.

Abstract
When a stereo image recognition device detects a vehicle ahead, a driving support apparatus extracts the vehicle ahead as a vehicle against which control should be performed, and performs driving support control based upon the information from the stereo image recognition device. When the stereo image recognition device does not detect the vehicle ahead, the driving support apparatus sets either one of the distance from the driving lane on which the vehicle travels and a start point of a curve ahead according to the configuration of the road ahead and a detection limit distance of the information of the vehicle ahead by the stereo image recognition device (front recognition device) as a threshold value IVC_L. When the vehicle ahead is present distant by more than the threshold value IVC_L, the driving support apparatus performs driving support control based upon the information by the inter-vehicle communication from a communication device.
