US 2017/0282658 A1 · TRAILER COUPLING SYSTEM

Abstract

The present invention relates to systems for guiding a vehicle to a trailer that can easily be installed or removed, and in particular relates to systems for guiding a vehicle to a trailer to facilitate coupling the vehicle and trailer together. The present invention is a means and a method for continuously determining the heading and/or distance to the trailer to assist a driver to couple a vehicle and trailer together. A device containing an inertial measurement unit is manually positioned proximate to the hitch ball of the vehicle and then positioned proximate to the coupler of the trailer and the motion is tracked and stored to enable the desired path between the two positions to be plotted. This path is then used to guide the driver in bringing the hitch ball and coupler together.

Dependent claims

A method for guiding a vehicle to a trailer for the purpose of coupling comprising the steps of (i) providing a device comprising an IMU and a processor that is able to record data,

(ii) positioning the device such that it is proximate to the hitch ball of the vehicle,
(iii) utilizing the IMU to record an initial value for a heading from step ii, (iv) positioning the device proximate to the trailer's coupler, (v) utilizing the IMU to determine a distance and direction from the position in step ii to the position in step iv, (vi) determining a change in the distance and direction from the hitch ball of the vehicle to the trailer's coupler as the vehicle reverses, (vii) determining a new distance and direction by adjusting the distance and direction determined in step v by the change in the distance and direction determined in step vi.
