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. The motor controller implements a protection feature that limits over-currents when the landing gear legs are engaged to the ground or retracted to their static position, or when a fault occurs.

A landing gear assembly includes a leg assembly including a first portion and a second portion, wherein the first and second portions of the leg assembly telescopingly engage one another, a gear assembly operably coupled to the first and second leg portions and configured to telescopingly move the first and second leg portions with respect to one another, and a drive assembly operably coupled to the gear assembly, and including a planetary gear arrangement configured to drive the gear assembly at a first speed and at a second speed that is different than the first speed, and a motor configured to drive the planetary gear assembly.

The invention concerns a method for unparking a motor vehicle (1) from a cross-parking space (8), with which the motor vehicle (1) is manoeuvred along an unparking trajectory (9) at least semi-autonomously from the cross-parking space (8) onto a road (10) bounding on the cross-parking space (8), wherein during said semi-autonomous manoeuvring of the motor vehicle (1) along the unparking trajectory (9), at least one reversing movement is carried out, an end position (E) is determined and the semi-autonomous manoeuvring of the motor vehicle (1) along the unparking trajectory (9) is ended at the end position (E), wherein the end position (E) is defined as at least a position such that in the event of further movement of the motor vehicle (1) from the end position (E) being carried out, manual control of the motor vehicle (1) in a driving direction (13) predetermined by the road (10) can be carried out by a driver of the vehicle without manoeuvring the motor vehicle (1) in a forward movement.

An automobile includes a plurality of frame-integrated hydraulic jacks includes a trunk mounted control panel in electrical communication with a power source and a plurality of jacks each being located beneath the automobile frame adjacent each wheel of the automobile. A plurality of flashing illumination is disposed upon the base of each jack and are in electrical communication with the control panel. The control panel permits a user to selectively raise or lower the automobile by the actuation of the plurality of jacks.

Methods of manufacturing mats for use as support surfaces include mixing pre-used material with virgin material to form a blended material and forming the mat for use as a support surface from the blended material. Mats for use as support surfaces include a body having a composition of at least 30% by weight of pre-used material and the remainder being virgin material.

A stabilizer for a vehicle includes an actuator assembly configured to be coupled to a chassis of the vehicle and a ground pad coupled to the actuator assembly. The actuator assembly is selectively repositionable between an extended position and a retracted position to reconfigure the stabilizer between a lifting configuration and a storage configuration. The ground pad has a bottom surface configured to engage a support surface below the chassis. When the stabilizer is in the lifting configuration, the bottom surface of the ground pad engages the support surface. When the stabilizer is in the storage configuration, the ground pad is not in contact with the support surface.

An outrigger device that is mounted on a vehicle and can switch between a usage state and a storage state includes: a lateral outrigger that extends in a vehicle width direction of the vehicle; a vertical outrigger that is extendable and is rotatably coupled to a leading end portion of the lateral outrigger; a first coupling member that constantly couples a first part of the vertical outrigger to the lateral outrigger and serves as a rotational center of the vertical outrigger; a second coupling member that can switch between a first state where a second part of the vertical outrigger is coupled to the lateral outrigger and a second state where the second part is uncoupled from the lateral outrigger; a conversion mechanism that converts a retraction of the vertical outrigger into an upward rotation of the vertical outrigger; and a safety device that prohibits an operation of the conversion mechanism in the first state and permits the operation of the conversion mechanism in the second state.
