Device and method for automatically adjusting the horizontal ride level of a utility vehicle
First Claim
1. A device for automatically adjusting the horizontal ride level of a utility vehicle, the utility vehicle having a vehicle body, a pivoting element pivotable about one of a longitudinal axis and a transverse axis and a ride-level-control system having spring elements of adjustable length, and a control unit, the device comprising a sensor for sensing an angle between the vehicle body and horizontal, the sensor being connectable to the control unit to trigger a ride-level-control process as a function of the sensed angle, the control unit being configured to lower the center of gravity of the vehicle body before commencement of one of a side-type and rear-type dumping process by maximum shortening of the spring elements.

Abstract
A device and a method for improved automatic ride level control of a utility vehicle on an inclined underlying surface use a lateral acceleration sensor to sense the inclination of the utility vehicle in the stationary state or with a reduced speed in conjunction with a chassis of adjustable height.

11. A method for automatically adjusting the horizontal ride level of a utility vehicle having a vehicle body having a pivoting element pivotable about one of a longitudinal axis and a transverse axis, and a ride-level-control system including spring elements of adjustable length and a control unit, the method comprising the steps of:
-
lowering the center of gravity of the vehicle body before commencement of one of a side-type and rear-type dumping process by maximum shortening of the spring elements; sensing an angle between the vehicle body and horizontal using a sensor; and triggering a ride-level-control process by the control unit as a function of the sensed angle. - View Dependent Claims (12, 13, 17, 18, 19, 20)
