Abstract:
An automatic deceleration control method for automatically decelerating a vehicle in accordance with a turning state of the vehicle, thereby stabilizing the turning behavior of the vehicle, comprising the steps of:(a) detecting the turning state of the vehicle;(b) detecting a friction coefficient of a road surface on which the vehicle is running;(c) setting a safe vehicle speed in accordance with the turning state detected in said step (a) and the road friction coefficient detected in said step (b) such that the safe vehicle speed is set at a value which increases with increase in the road friction coefficient, when the road friction coefficient falling within a medium or low region is detected in said step (b);(d) setting a safe vehicle speed in accordance with the turning state detected in said step (a) and the road friction coefficient detected in said step (b) while restraining increase of the safe vehicle speed when the road friction coefficient falling within a high region is detected in said step (b); and(e) automatically decelerating the vehicle so as to cause the actual vehicle speed to be equal to or less than the safe vehicle speed set in said step (c) or (d) when a turning motion of the vehicle is detected in said step (a).
