IPC: G08G1/16
Filed: 2020-04-16
Abstract: To make it possible to limit an unnecessary collision avoidance operation, even when predicting a collision upon suddenly meeting at an intersection.SOLUTION: A one's own vehicle position estimating part 6a detects an approaching intersection by referring to road map information based on an estimated position of one's own vehicle M. A crossing vehicle recognition part 6b recognizes a crossing vehicle I approaching the intersection based on surrounding environmental information acquired by a surrounding environmental recognition unit 2. A collision prediction calculation part 6c compares intersection entering times TM, TI of the one's own vehicle M and the crossing vehicle I to predict a collision upon suddenly meeting of both the vehicles M. I. An AEB operation determination part 6e determines that a collision avoidance operation with respect to the one's own vehicle M is unnecessary, when a front vehicle recognition part 6d recognizes vehicles P, O entering the intersection earlier than the one's own vehicle M, even when the collision prediction calculation part 6c predicts that the one's own vehicle M collides with the crossing vehicle I.SELECTED DRAWING: Figure 1
