Abstract: A vehicle leveling assembly includes a plurality of jack assemblies corresponding to four quadrants of a vehicle, and a plurality of sensors for determining jack position and rate of movement. A method of detecting contacting between the shafts of the jack assemblies and the ground includes measuring pulse width of current emitted by the hall effect sensor to monitor the speed of the shafts and recognizing contact with the ground when the shaft slows down. A method of detecting contacting between the shafts of the jack assemblies and the ground includes measuring the electric motor current signal and correlating a pulse from the current signal to the electric motor revolutions per minute and travel of the shafts. A method of calibrating the leveling assembly includes measuring a change in inclination as the jack assemblies are extended a known distance to determine the distance between the jack assemblies.

Abstract: A motor vehicle seat adjuster includes a DC motor and a control system operably connected to the motor to control seat motion to a desired motion profile. Power to the motor is variable from less than 100% of normal power to greater than 100% of normal power. The desired motion profile preferably includes a normal operating power and a boost operating power and the control system automatically increases motor power to the boost operating power after one of a predetermined period of time, a predetermined distance of travel, or a predetermined sensed condition. Parameters of the motion profile are preferably customizable.

Abstract: A shifter mechanism for a motor vehicle includes a shifter lever, a park switch indicating when the shifter lever is out of a park position, and an electric actuator movable between a locking position and an unlocking position to lock and unlock the lever. An interlock switch indicates when the vehicle operator desires to move the lever. A controller moves the actuator when an ignition switch indicates an ignition is on, a brake switch indicates a brake pedal is pressed, and the interlock switch is actuated. The controller also moves the actuator when the lever is not in the park position and the interlock switch is actuated. The controller actuates a vehicle key lock actuator when the ignition switch indicates the vehicle ignition is on or when the park switch indicates that the lever is not in the park position.

Abstract: An adjustable control pedal includes an upper arm, a lower arm, and a drive assembly operatively connected to the lower arm to selectively move the lower arm relative to the upper arm. The drive assembly includes a drive screw, a drive nut cooperating with the drive screw such that the drive nut travels along the drive screw upon rotation of the drive screw, and an electric motor to selectively rotate the drive screw. A hall-effect sensor is located adjacent the drive screw and cooperates with a ring magnet rotatable with the drive screw to detect motion information, including distance and velocity information, upon rotation of the drive screw. The controller determines stall conditions of the lower pedal arm between the limits of travel based on the velocity information received during movement of the lower pedal arm to reduce injury or damage resulting from engagement with obstructions.

Abstract: An adjustable control pedal for a motor vehicle includes an upper arm, a lower arm supported by the upper arm and operatively connected to the upper arm for selected movement relative to the upper arm, and a drive assembly operatively connected to the lower arm to selectively move the lower arm relative to the upper arm. A hall-effect sensor is located adjacent a drive screw and cooperates with a ring magnet rotatable with the drive screw to detect motion information. A controller receives the motion information and activates an electric motor upon initialization of the controller to move the lower pedal arm in a first direction until a first mechanical stop is engaged and establish a home stop position and to move the lower pedal arm in the other direction until a second mechanical stop is engaged and establish a travel stop position.
