ABSTRACT:
A method and device for detecting the stroke limit of an electric motor-driven jack while the jack is being used to adjust the attitude of a mobile platform. A controller is programmed to detect when an electric jack motor has driven a jack to a jack stroke limit by monitoring one or more jack motor power draw characteristics and comparing those values to known values associated with the driving of a jack at or near the end of a jack stroke.
