Abstract: The present invention is an electric powered landing gear system for semi-truck trailers using an electric motor supplied by the available voltage in the trailer via a motor controller. The system automates raising and lowering the landing gear. The system comprises a shaft motorized system operated by a 3-phase motor, a DC-to-AC motor controller, and a set of sprockets-and-chain mechanism. The electric motor implements a 3-phase winding and a brushless structure that requires no maintenance compared to direct current motors. The trailer provides the power for the electric motor through the motor controller. The motor controller comprises a digital electronic processor that implements an algorithm to optimize a sensorless control approach providing a variable speed and torque for the motor, and hence to the landing gear system, therefore simplifying the landing gears to a single speed from dual (or multi) speed/gear ratio.

Abstract: A system for automatically moving a stabilizer of a work vehicle is disclosed. A joystick is connected to an electronic controller, which in turn, is connected to valve drivers to drive stabilizer raising and lowering valves. In one mode of operation, the controller is programmed to move the stabilizers up or down at a rate that is proportional to the deflection of the joystick from a neutral position. If the operator holds the joystick in a certain position or range of positions, the controller enters a second mode in which it automatically raises the stabilizers even if the joystick is released. The stabilizer can be placed in a third mode of operation by moving the joystick rapidly back and forth. When the operator does this, the controller is configured to reduce the ramp rate or damping of its response to joystick movement.
