Integrating UPnP with Automotive On-Board Diagnostics and Automatic Clipboard Sharing

Disclosed is a method that uses UPnP (Universal Plug and Play) technology in the following situations:

 

  • Combines UPnP with automotive on-board diagnostic (OBD) technology
  • Uses UPnP to automatically share a computer’s clipboard

Benefits include streamlining tedious tasks and quickly sharing data and files.

Background

Since the introduction of OBD, cars and trucks sold in the United States have been required to include a diagnostic port to interface to the engine computer. This provides almost complete engine control and also monitors parts of the emissions system, chassis, body and accessory devices, as well as the diagnostic control network of the car.� UPnP was designed with the goal of supporting self configured, ad hoc networks, or networks that require little or no administration. To access any information contained in an engine computer, an interface is connected to the diagnostic connector, which deciphers the information from the signal as it comes through the wire.

In office environments, seamless exchange of data is essential, but new data exchange techniques are only successful if they are easy to use and well integrated within existing usage models.

General Description

The disclosed method uses UPnP technology to facilitate easy access to information via automobile ODB ports, and to easily share information on a computer’s clipboard.

Automotive OBD

The disclosed method categorizes the diagnostic information contained within the engine computer, and exposes it as categorized UPnP services contained within their respective UPnP device (see Figure 1). For example, to access the Fuel Injector Flow Rate, the data is stored in the following Device Tree:� Powertrain ► Engine ► FuelSystem ► FuelInjector; within the Fuel Injector device is the Flow Meter service, which contains GetFlowRate and GetMaxFlowRate actions. The entire automotive diagnostic system is structured in the same fashion. Exposing these devices and services can...
