Abstract:
1. A hitch apparatus for connecting a self-propelled trailing vehicle to a self-propelled leading vehicle, and for measuring the position of the trailing vehicle relative to the leading vehicle, the hitch apparatus comprising: a first hitch assembly for connecting a rear end of the leading vehicle to a front end of the trailing vehicle, the first hitch assembly including a swivel base mounted on a substantially vertical pivot shaft and a housing, in which the shaft is pivotally mounted, adapted for mounting at the rear end of the leading vehicle; a first angle sensor connected to and supported by the housing, the first angle sensor being operatively connected to the pivot shaft and capable of measuring a horizontal angle between a centerline of the swivel base extending through the pivot shaft and a longitudinal centerline of the leading vehicle, the first angle sensor capable of transmitting an electrical signal indicative of a measured horizontal angle to a control system; a second hitch assembly for mounting on the front end of the trailing vehicle, the second hitch assembly including a connecting device mounted on the front end of the trailing vehicle and connectable to the swivel base during use of the apparatus; and a distance sensor for measuring a variable distance between a preselected point at the front end of said trailing vehicle and the swivel base and transmitting an electrical signal indicative thereof to the control system.
