Running control device for a vehicle
First Claim
1. A cruise control system for an automotive vehicle, for controlling cruising of own vehicle with maintaining a distance to a preceding vehicle constant, comprising:
- traffic signal characteristics obtaining means for obtaining characteristics of a traffic signal ahead;
road information obtaining means for obtaining intersection information including a distance to an intersection;
intersection arrival time calculating means for calculating arrival timing of the own vehicle and the preceding vehicle on the basis of a distance to the intersection, an own vehicle speed and a preceding vehicle traveling condition;
traffic signal condition estimating means for estimating said condition of the traffic signal on the basis of the traffic signal characteristics and said intersection arriving time; and
control content modifying means for modifying a content of cruise control of the own vehicle depending upon said estimated traffic signal condition.

Abstract
A cruise control system for an automotive vehicle controls a speed of own vehicle estimating conditions not only when the own vehicle passes through the intersection but also when the preceding vehicle passes through the intersection, for permitting travel on the ordinary road with a given distance. The cruise control system includes traffic signal characteristics obtaining means for obtaining characteristics of a traffic signal ahead, road information obtaining means for obtaining intersection information including a distance to an intersection, intersection arrival time calculating means for calculating arrival timing of the own vehicle and the preceding vehicle on the basis of a distance to the intersection, an own vehicle speed and a preceding vehicle traveling condition, traffic signal condition estimating means for estimating the condition of the traffic signal on the basis of the traffic signal characteristics and the intersection arriving time and control content modifying means for modifying a content of cruise control of the own vehicle depending upon the estimated traffic signal condition.
