Vehicle driving support apparatus with target position arrival determination
First Claim
1. A vehicle driving support apparatus, comprising:
- own vehicle travel information detecting means for detecting travel information of an own vehicle;
front vehicle information detecting means for recognizing a vehicle in front of the own vehicle and detecting information of the front vehicle;
control target time setting means for setting a time required to reach a target position (P1) set before the front vehicle as a control target time;
front vehicle estimated position computing means for computing an estimated position of the front vehicle as of when the control target time elapses;
target acceleration computing means for computing a target acceleration of the own vehicle on the basis of the estimated position of the front vehicle and a target inter-vehicle distance such that an inter-vehicle distance between the own vehicle and the front vehicle matches the target inter-vehicle distance when the control target time elapses; and
acceleration/deceleration control means for performing acceleration/deceleration control on the basis of the target accelerationwherein the target inter-vehicle distance is computed based on the control target time and a speed of the own vehicle.

Abstract
In automatic following control in a travel control unit of a driving support apparatus, a prerequisite inter-vehicle distance to a front vehicle is set, a time to reaching this requisite inter-vehicle distance is set as a control target time, an estimated position of the front vehicle after the control target time elapses is computed, an acceleration from a present vehicle speed that will bring to a preset target inter-vehicle distance the inter-vehicle distance to the front vehicle at an own vehicle speed as of when the control target time elapses is computed as a target acceleration on the basis of the present inter-vehicle distance to the front vehicle and the estimated position of the front vehicle after the control target time elapses, and automatic braking control and automatic acceleration control are carried out to follow the front vehicle.
