Problems solved by technology

Most trailers have minimal wiring configured to power these types of electrical components, but there is no separate data connection designed to exchange information between the vehicle and trailer
Wireless connections may be used to connect devices on the trailer to devices on the vehicle, however, wireless connections may be susceptible to interference and other undesired effects

Embodiment Construction

[0012] The systems and methods described herein are generally designed to provide communication between the vehicle and trailer over existing power lines and connections. In one embodiment, the system is arranged such that the video output of a rear view camera mounted at the end of the trailer is provided to a visual display inside the vehicle, and over the same power lines used for electrical devices such as the trailer taillights. This allows the driver to "see" behind the trailer without having to add dedicated communication lines connecting the camera to the visual display. In various embodiments, an electronic control unit (ECU) in the vehicle sends brake control signals to one or more brake devices on the trailer via existing power lines in order to control trailer stability issues, such as trailer sway. In this way, the powerful ECU already present in the vehicle can be used to control certain aspects of trailer operation without having to provide dedicated communicati...

Abstract

A method and system for communication between a vehicle and a trailer over existing power lines, such as by using a power line communication (PLC) arrangement. A PLC modem may convey data over electrical power that is supplied on the power lines and / or may elicit data from electrical power supplied on the power lines. This enables one or more electronic control units (ECUs) on the vehicle to communicate with input / output devices on the trailer, such as rearward-facing cameras or braking devices, without having to provide separate, dedicated communication lines therebetween.

Description

technical field [0001] The present invention relates generally to communications between a vehicle and a trailer, and more particularly to communications carried over power lines connected between the vehicle and the trailer. Background technique [0002] Many vehicles can be equipped with some type of towing package, which usually includes a trailer hitch and a trailer coupler. The trailer connector provides power from the vehicle to the trailer and powers electrical components on the trailer such as the taillights and / or electric brakes. Most trailers have minimal wiring configured to power these types of electrical components, but no separate data connection designed to exchange information between the vehicle and trailer. Wireless connections may be used to connect devices on the trailer to devices on the vehicle, however, wireless connections may be susceptible to interference and other undesired effects. [0003] Therefore, there is a need for reliable and cost-effec...
