1. A vehicle trailer system comprising:
- a trailer chain including a sensor that transmits data indicative of a chain position; and
a controller configured to;
in response to data indicating a secured chain position, illuminate a light at a first frequency,in response to data indicating an unsecured chain position, illuminate the light at a second frequency; and
in response to data indicating an unconnected chain position, illuminate the light at a third frequency.

Abstract
A vehicle includes a controller and a frame having a receiver including an electrical connector configured to connect to a trailer having a plurality of chains. The plurality of chains each includes a sensor configured to transmit a position of the chain relative to a winch disposed on the trailer. The controller is configured to, in response to data from the sensors indicating a position of the chains, display via an interface a connection status of the chains.

4. A vehicle comprising:
-
a frame having a receiver including an electrical connector configured to connect to a trailer having a plurality of chains that each include a sensor configured to transmit a position of the chain relative to a winch disposed on the trailer; a light attached to the receiver and connected to the sensors such that a position of at least one of the sensors relative to the winch being below a threshold illuminates the light, wherein the light at a first frequency to indicate a proper connection between the chains and the winch, illuminate the light at a second frequency to indicate an improper connection between the chains and the winch, and illuminate the light at a third frequency to indicate an unconnected position; and a controller configured to, in response to data from the sensors indicating a position of the chains, display via an interface a connection status of the chains. - View Dependent Claims (5)

6. A control method for a trailer hitch safety system comprising:
-
in response to sensor data from a trailer safety chain, indicative of an arrangement of the safety chain relative to a winch disposed on a trailer being in a secured position, display, via an interface, indicia representing a proper chain connection such that a light illuminates at a first frequency; in response to sensor data from the trailer safety chain, indicative of an arrangement of the safety chain relative to a winch disposed on the trailer being in an unsecured position, display, via an interface, indicia representing an improper chain connection such that the light illuminates at a second frequency; and in response to sensor data from the trailer safety chain, indicative of an arrangement of the safety chain being in an unconnected position, illuminate the light at a third frequency. - View Dependent Claims (7, 8, 9)
