Abstract
Provided is a so-called active suspension controller for a vehicle especially effective during turning. The controller comprises: an actuator provided between the body and every wheel of the vehicle; sensors for a turning condition of the vehicle, here the turning condition including a steering angle, vehicle speed, yaw rate and others; and a control apparatus responsive to the sensed turning condition for driving the actuators in order to control the allotment ratio between the front and the rear axles of the load shift between the right and the left wheels. The allotted load shift realizes stable turning under various circumstances.

A controller for suspensions of a vehicle, comprising:
- an actuator provided between the body and every wheel of the vehicle;
- means for sensing a turning condition of the vehicle, the turning condition including a steering angle;
- and
- control means responsive to the sensed turning condition for driving the actuators in order to control the allotment ratio between the front and the rear axles of the load shift between the right and the left wheels so as to control steering characteristics of the vehicle.
