Differential action control system of a vehicle

Abstract

A differential action control device of a vehicle includes an inter-axle differential disposed between axles for making a differential action between the axles, an inter-wheel differential disposed between wheels for making a differential action between the wheels, and a parameter setting device for detecting a vehicle running condition and setting a predetermined parameter based on the vehicle running condition detected. The device further includes target yaw rate setting device for setting a target yaw rate of the vehicle based on the parameter, a yaw rate detecting device for detecting an actual yaw rate of the vehicle while running, and a differential control device for controlling a differential action of the inter-axle and inter-wheel differentials based on a deviation between the actual and target yaw rate of the vehicle. The steering characteristic of the vehicle can be changed to get a desirable characteristic by making the differential action control.
