VEHICLE ACTIVE SUSPENSION SYSTEM
First Claim
1. In a vehicle active suspension system having an actively controllable actuator for controlling movement of a second vehicle part relative to a first vehicle part upon which the second part is resiliently supported, a sensor for sensing a parameter of the vehicle, and a control unit for controlling the actuator as a function of the sensed parameter, characterized by:
- the control unit, in response to the sensed parameter, actively controls the actuator to move the second part relative to the first part in order to make a non-optimal operating condition noticeable to an operator of the vehicle.

Abstract
The invention relates to a vehicle active suspension system. There is a need for an active suspension system which can alert an operator to certain conditions. The suspension system includes an actuator for moving a second vehicle part relative to a first vehicle part. The suspension system also includes sensors and a control unit. A vehicle operator is located in or on the second part. The sensors sense vehicle parameters and transmit parameter signals to the control unit. In response to the parameter sensors, the control unit causes the actuator to move the second part in such a manner that the movement alerts the operator to the existence of a condition, such as a critical or non-optimal operating state of the utility vehicle or of an implement coupled to the vehicle.

24. A method of operating a vehicle suspension system having an actively controllable actuator for controlling movement of a second vehicle part relative to a first vehicle part upon which the second part is resiliently supported, a sensor for sensing a parameter or a condition, and a control unit for controlling the actuator as a function of the sensed parameter, wherein the method comprises:
-
sensing a parameter or condition; and in response to the sensed parameter or condition, actively moving the actuator to make the operator aware of the parameter or condition.
