Abstract:
1. Apparatus for leveling a vehicle, comprising: a right front leg, a left front leg, a right rear leg, and a left rear leg mounted to the vehicle, each leg being independently adjustable between a stowed position and an extended position wherein the leg engages the ground; a sensor mounted to the vehicle to sense the pitch and roll of the vehicle relative to a reference level plane, the sensor producing an orientation signal representing the vehicle pitch and roll; a controller coupled to the legs and the sensor, the controller responding to an operator command to level the vehicle relative to the reference level plane by actuating the legs such that they move from their stowed position to their extended position, interpreting the orientation signal to determine an end and a side of the vehicle which is above the reference level plane, then alternating between adjusting the end and the side downwardly by retracting the legs at the end and retracting the legs at the side, each leg being retracted for a first predetermined period of time during each downward adjustment.
