Abstract:
1. A vehicle control system, which is configured to change an index for setting driving characteristics of a vehicle, wherein: the index is changed according to acceleration of the vehicle; a manner of changing the index is differentiated depending on a detail of an operation for changing acceleration executed by a driver; the index determined on the basis of a large absolute value of the acceleration is inhibited to be lowered to the index to be determined on the basis of a small absolute value of the acceleration, in case an amount of the operation or a change rate of the amount of the operation is large; and the index determined on the basis of a large absolute value of the acceleration is facilitated to be lowered to the index to be determined on the basis of a small absolute value of the acceleration, in case an amount of the operation or a change rate of amount of the operation is small; the index is configured to increase agility of the vehicle by being increased; an instant index is determined by synthesizing absolute values of a longitudinal acceleration and a lateral acceleration of the vehicle; the index is increased to an increased value of the instant index which is larger than a prior value; the index is lowered after a delay with respect to a drop of the instant index from said increased value at which the index is maintained; and the index determined on the basis of a large absolute value of the acceleration is inhibited to be lowered to the index to be determined on the basis of a small absolute value of the acceleration, by extending time to hold a current value of the index, in case an amount of the operation or a change rate of the amount of the operation is large.
