Abstract:
An integrated jacking system includes built-in jacks for each wheel of the vehicle. Electric motor-driven screw or worm-gear jacks are welded to the vehicle frame or unibody aft of the front wheels and forward of the rear wheels. The four jack screws each terminate on the lower end in a rotatable ball-jointed footing adaptable to uneven drive surfaces beneath the vehicle wheels. The integrated jacking system is controlled by the vehicle computer through a passcode-accessible central jacking control interface. The vehicle computer is programmed to implement safety protocols: allowing only one wheel at a time to be jacked up, limiting jacking height of a wheel to not more than six inches (6″) off the ground, and disabling the jacking system if the grade of the underlying surface exceeds twenty percent (20%) or if the parking brake is not set.
