Steering input apparatus for trailer backup assist system
First Claim
1. A trailer backup steering input apparatus for providing a trailer steering information signal to a trailer backup assist control module of a vehicle through a signal interface thereof, the trailer steering information signal is configured for enabling the trailer backup assist control module to generate electrical steering commands for a steering system of the vehicle as a function of the trailer steering information signal, the trailer backup steering input apparatus comprising:
- a user interface through which trailer path altering commands are inputted with respect to a zero curvature commanding position;
a signal generator that generates the trailer steering information signal as a function of the trailer path altering commands;
a signal interface connectable to the signal interface of the trailer backup assist control module for enabling the trailer steering information signal to be transmitted from the trailer backup steering input apparatus for reception by the trailer backup assist control module; and
an enclosure having the user interface, the signal generator, and the signal interface mounted thereon such that the trader backup steering input apparatus is able to be selectively placed by a driver of the vehicle with respect to a structure to which the trailer backup assist control module is mounted.

Abstract
A trailer backup steering input apparatus provides a trailer steering information signal to a trailer backup assist control module of a vehicle through a signal interface thereof. The trailer steering information signal is configured for enabling the trailer backup assist control module to generate electrical steering commands for a steering system of the vehicle as a function of the trailer steering information signal. The trailer backup steering input apparatus is self-contained and physically detachable/detached form the vehicle. Advantageously, such a trailer backup steering input apparatus saves space, allows for greater flexibility with interior styling of the vehicle, and allows all drivers regardless of stature the ability to have the trailer backup steering input apparatus easily accessible while utilizing the trailer backup assist functionality of the vehicle.
