Method for estimating running environment, driving support method and running environment estimating device

摘要

The purpose of this study is to improve the estimation accuracy of the estimation of the factors that impede the driving of the preceding car.In the running environment estimation methodThe position of the preceding vehicle 3 running ahead of the vehicle 1 is detected on the road 2 running by the vehicleA detectable area (6a), an area in which the occupant of the preceding vehicle 3 can be viewed or an object detecting portion of the preceding vehicle 3 can detect an object around the preceding vehicle6B).A detectable area (6a) for a predetermined period of timeChanges in 6B.Or, the detectable area (6a), while the preceding vehicle runs a predetermined distanceDetection of the amount of change in the area, which is the amount of change ofIn the case where the preceding vehicle detects the lane change from the first lane 2a to the second lane 2b on the road within the first predetermined time after detecting the amount of change in the area above the threshold value,It is presumed that there is a driving inhibiting factor which is a factor inhibiting running of the vehicle on the first lane 2a and the front of the preceding vehicle 3.Diagram
