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.
