摘要： PROBLEM TO BE SOLVED: To provide a collision avoidance system, capable of avoiding the collision of its own vehicle to an obstacle, even when the obstacle in the periphery of the own vehicle, such as an automobile and motorbike, performs acceleration/deceleration or turn not expected by the driver. SOLUTION: When the obstacle performs acceleration/deceleration or turn based on the moving performance of the obstacle detected by an obstacle detection means, an action range estimation means 41 estimates an action range of the obstacle which can exist after a predetermined period. Further, based on a road surface condition on which the own vehicle and the obstacle exist and an action history of the obstacle, an action probability estimation means 42 estimates an action probability with which the obstacle can exist in the above action range. A driving operation support means 43 generates a locus capable of avoiding advancing of the own vehicle to the estimated action range or a position having a high action probability and vehicle movement control information necessary for running on the locus, so as to support the operation with an indication and a warning to the driver. With this, even when the obstacle performs an action not expected by the driver, it is possible to reduce the collision possibility of the own vehicle with the obstacle. COPYRIGHT: (C)2008,JPO&INPIT
