METHOD OF CALCULATING DIMENSIONS OF A TOWED VEHICLE
First Claim
1. A method of calculating at least one dimension of a towed vehicle, the method comprising:
- sensing an image of the towed vehicle with an image sensing device;
identifying a feature on the towed vehicle in the sensed image of the towed vehicle with a controller using a dimension determination algorithm; and
determining the at least one dimension of the towed vehicle from the identified feature of the towed vehicle, with the controller using the dimension determination algorithmwherein determining the at least one dimension of the towed vehicle from the identified feature of the towed vehicle includes using one of either a stereo disparity ranging process, or a structure from motion ranging process.

Abstract
A method of calculating at least one dimension of a towed vehicle includes sensing an image of the towed vehicle with an image sensing device. A feature on the towed vehicle in the sensed image of the towed vehicle is identified with a controller using a dimension determination algorithm. The dimension of the towed vehicle is determined from the identified feature of the towed vehicle, with the controller using the dimension determination algorithm. The dimension of the towed vehicle may be input into a vehicle tow controller, to enable the vehicle tow controller to control the tow vehicle.

17. A method of controlling a tow vehicle having a towed vehicle connected thereto, the method comprising:
-
sensing an image of the towed vehicle with an image sensing device; determining at least one dimension of the towed vehicle from a feature of the towed vehicle that is identified from the sensed image of the towed vehicle, with a controller using a dimension determination algorithm;
wherein the dimension determination algorithm is operable to;identify a feature on the tow vehicle having a known dimension, from the image of the towed vehicle hitched to the tow vehicle; and determine the at least one dimension of the towed vehicle based on the known dimension of the identified feature on the tow vehicle; uploading the at least one dimension of the towed vehicle to a vehicle tow controller of the tow vehicle; and controlling the tow vehicle with the vehicle tow controller based on the at least one dimension of the towed vehicle. - View Dependent Claims (18, 20)
