  • Patent number: 10093286
    Abstract: An example leveling/stabilization system for a vehicle includes a jack, an actuator, a user interface device, and a controller. The jack is adapted to be fixed to the vehicle and is extendable from a stowed position to an auto-deployed position. The actuator is coupled to the jack and is operative to extend and retract the jack responsive to signals from the controller. The user interface device is adapted to receive input from a user. The controller is responsive to an auto-deploy signal from the user interface and operative to provide the control signals to the actuator causing the actuator to continuously extend the jack from the stowed position for a predetermined time period, thereby positioning the jack in the auto-deployed position. No level sensor is required.
