Abstract:
A curve approach control apparatus comprising:an allowable lateral acceleration setting means for setting as an allowable lateral acceleration a lateral acceleration that a vehicle can tolerate when it negotiates a curve in front; an allowable approach speed setting means for setting as an allowable approach speed an approach speed at which the vehicle can negotiate the curve, based on at least the allowable lateral acceleration; a decision control means for estimating and judging an approach of the vehicle to the curve based on at least the allowable approach speed and execute a predetermined control; and a road surface friction coefficient estimation means for estimating a road surface friction coefficient; wherein said allowable lateral acceleration setting means corrects, according to the road surface friction coefficient, an allowable percentage of the lateral acceleration that occurs in the vehicle as it negotiates the curve and sets the allowable lateral acceleration.
