Abstract
A vehicle 10 includes an electric actuator system 11 that operates according to a method 12 to move the vehicle 10 from an un-level condition to a level condition. The system 11 includes electric actuators 22-25 disposed substantially near the four corners of the vehicle 10 and a controller 32, 33 in electric communication with each of the actuators. The method 12 includes providing electric power at a first predetermined power level to two of the actuators to level the vehicle 10 along one of its X and Y axes. The method 12 further includes simultaneously sensing the attitude of the vehicle 10 along the other of its axes, and changing the power level provided to at least one of the powered actuators to a second predetermined power level to maintain the attitude along the other axis within a predetermined range.
