A suspension device has longitudinal force compliance steer properties to steer a rear wheel to toe-in or toe-out according to increase in longitudinal force applied to wheel treads of a rear wheel. The suspension device includes: a hub bearing housing; suspension links having both edges pivotally attached to a vehicle body and a hub bearing respectively, to support the hub bearing housing; a suspension spring generating reaction force corresponding to relative displacement amount in the longitudinal direction of the hub bearing housing as to the vehicle body; a damper generating damping force corresponding to relative speed in the longitudinal direction of the hub bearing housing as to the vehicle body; and a toe change generating unit generating toe change in a direction where toe change due to longitudinal force compliance properties is temporarily cancelled out or suppressed at an early stage of turning of the vehicle.

Suspension device

A multiple disk clutch is provided for a rear wheel differential of a vehicle. A restricting torque for the clutch is set by vehicle speed, longitudinal acceleration and lateral acceleration of the vehicle. A large steering angle at a low vehicle speed is detected in accordance with the vehicle speed and a steering angle. In response to the restricting torque and a detected large steering angle at a low vehicle speed, the clutch is operated to reduce a restricting operation for the clutch.

Control system for a differential of a motor vehicle

An ideal lateral acceleration is calculated based on vehicle speed and steering angle, and an actual lateral acceleration is calculated based on a lateral acceleration detected by a lateral G sensor. A breakaway point of tires is determined by comparing the actual lateral acceleration with the ideal lateral acceleration. A differential operation of a central differential is controlled by restricting the differential operation in accordance with a determined breakaway point and the difference between the ideal lateral acceleration and the actual lateral acceleration.
