Suspension system for motor vehicle having variable suspension characteristics.

摘要

Suspension mechanisms for motor vehicles include dampers of variable damping powers and air springs of variable spring coefficients so that the suspension characteristics are changed between soft and hard modes. The suspension mechanisms are provided with a controller for producing a control signal only when the differential value between the value of a last steering angle and an average value of steering angles is larger than a predetermined value to change the suspension characteristics to the hard mode. In accordance with this arrangement, the suspension characteristics are changed to the hard mode only when the rolling angle of the vehicle exceeds a predetermined value.
