1. A vehicle running control system comprising:
- front-environment recognition means mounted in a subject vehicle, the front-environment recognition means recognizing at least a preceding vehicle, and an inter-vehicle distance between the preceding vehicle and the subject vehicle;
right/left turn judging means for judging a right or left turn of the preceding vehicle on the basis of information about the preceding vehicle recognized by the front-environment recognition means; and
target inter-vehicle distance setting means for setting a target inter-vehicle distance between the subject vehicle and the preceding vehicle on the basis of one of a vehicle speed of the preceding vehicle calculated from the information about the preceding vehicle recognized by the front-environment recognition means and a speed of the subject vehicle, whereinthe target inter-vehicle distance is a target distance established for comparison with the recognized inter-vehicle distance,the target inter-vehicle distance includes a first target inter-vehicle distance set when the right/left turn judging means determines that the preceding vehicle is making a right or left turn, and a second target inter-vehicle distance set when the preceding vehicle is traveling straight ahead, andthe first target inter-vehicle distance is shorter than the second target inter-vehicle distance.

Abstract
At least a follow-up target inter-vehicle distance is set on the basis of information about a preceding vehicle recognized by a forward-environment recognition device mounted in a subject vehicle and including a stereo camera, and it is determined whether or not the preceding vehicle is making a right/left turn. When a right/left turn of the preceding vehicle is detected, the follow-up target inter-vehicle distance is multiplied by a correction coefficient so as to set a different follow-up target inter-vehicle distance for the right/left turn.
