CURVE APPROACH CONTROLLER

摘要

PROBLEM TO BE SOLVED: To set an allowable curve approach speed as a value suitable for the actual curve curvature radius even when the curve is a tight corner having a curve curvature radius set based on a node transmitted from a navigation device equal to or less than a prescribed ratio to road width. SOLUTION: When a curve curvature radius calculated by a front road attribute calculating part 25 based on node data transmitted from a navigation device 7 is a prescribed ratio or less to the road width of the curve, an allowable approach speed setting part 27 sets an allowable approach speed based on an allowable acceleration set by an allowable acceleration setting part 26 and the prescribed ratio to the road width. In this case, the prescribed ratio to the road width is set so as to be larger in an outer curve than that in an inner curve.
