Claim:
1. A vehicle driving control apparatus for controlling an own vehicle to track a target vehicle, the target vehicle being a preceding vehicle which runs ahead of the own vehicle and is selected by the vehicle driving control apparatus to be tracked by the own vehicle, the vehicle driving control apparatus comprising: means for acquiring an actual relative speed of the target vehicle to the own vehicle; means for detecting occurrence of an event, the event being one of: (i) a different preceding vehicle being selected by the vehicle driving control apparatus as the target vehicle; (ii) an intervening vehicle becoming the target vehicle by intervening between the preceding vehicle and the own vehicle; (iii) an override operation being completed by a driver of the own vehicle by accelerating or decelerating the own vehicle; and (iv) a tracking control being initiated by the driver of the own vehicle; means for setting a target acceleration of the own vehicle based on the product of a relative speed gain and the actual relative speed acquired by the acquiring means, the relative speed gain being set to a reference gain when occurrence of the event has not been detected by the detecting means; and means for correcting, in response to detection of occurrence of the event by the detecting means, the relative speed gain to increase, at a predetermined rate of increase for a predetermined time, the relative speed gain from a value that is less than the reference gain.
