    Abstract: Radio frequency identification tags are spaced apart from one another in or around a work area for the vehicle. Each of the tags has a corresponding unique identifier. A path planning module establishes a path comprising a path segment between at least two of the radio frequency identification tags. The path segment comprises at least one of a distance between the tags, an angular heading between the tags, and unique identifiers corresponding to the tags. A data processor determines an estimated position of the vehicle based on at least one of odometer data and accelerometer data. A vehicle controller navigates between at least two of the radio frequency identification tags based on the estimated position, the distance and the angular heading. A reader reads the tag identifiers of each tag to track the progress of the vehicle to facilitate execution of or retrieval of any next path segment of the vehicle along the established path.

    Abstract: A differential steering assist system is provided for an off road utility vehicle with a pair of steerable front wheels and at least one pair of driven left and right rear wheels. The system uses a steering position sensor and wheel speed sensors that sense the wheel speed of the driven left and right rear wheels. An electronic control unit provides speed reducing commands to the left or right rear wheels based on the sensed steering position and sensed wheel speed.
