ENTERING-DETERMINATION GEOGRAPHICAL POINT STORAGE SYSTEM, DRIVE SUPPORT SYSTEM, DRIVE SUPPORT METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide: an entering-determination geographical point storage system capable of storing an entering-determination geographical point, with correction to an appropriate position, the point used as a condition for passing through in performing a vehicle drive support, even in the situation of generating plural candidates of a vehicle present position; and a drive support system, a drive support method, and a computer program, which enable an appropriate vehicle drive support on the basis of the stored entering-determination geographical point.SOLUTION: When a deceleration action of a vehicle is performed, a deceleration-end target geographic point that is a deceleration-end geographic point used as a target when a decelerating action is performed on the vehicle is set on a road; an entering-determination start point that is used as a condition for passing through in performing a drive support of the vehicle is set before the deceleration-end target geographic point; and the entering-determination start point is set in avoidance of a section where plural candidates of the vehicle present positions are generated.
