Dearborn Group Technology's Wireless Diagnostics System

While DG Technologies provides for numerous wireless solutions across their extensive product line, our Gryphon-S3 based Wireless Diagnostic System is an example which allows remote communication with a vehicle to perform diagnostic and control functions.

The on-board communication device consists of the Gryphon hardware configured to communicate wirelessly over a standard 802.11b network with 128-bit encryption for data security. Gryphon is DG Technologies' versatile vehicle interface product powered by Linux OS. Gryphon also supports communication with the vehicle network over most protocols used by OEM's today. The Gryphon can be configured with up to 6 CAN protocol ports for interfacing systems including engine or countermeasure control.

The on-board device works in conjunction with an iPAQ based vehicle diagnostics application and is available in various vehicle manufacturer versions including Ford, GM and many others.

The diagnostics application supports two modes as described below:

Real-time Vehicle Diagnostics Mode: This mode is available when the diagnostics system is plugged into the vehicle via the J1962 connector on vehicles supporting OBDII diagnostics.

Simulation Mode: This mode is useful to interact with the diagnostics software in the absence of a vehicle.

In both modes the following features are supported:
Check status and retrieve Diagnostics Trouble Codes stored on the vehicle.
Display additional information related to Trouble Code for a subset of Trouble codes.
Monitor and display vehicle parameters available via OBDII requests.

DG Gryphon Wireless Capabilities - Example Demonstration
Gryphon wireless communication with a Jaguar XK8 demonstrated how users could manipulate various functions on the Jaguar using a PDA as a simple interface. The PDA was equipped with a wireless Ethernet card, which supports communication with the on-board web server on the Gryphon, which is connected to a vehicle. The Gryphon web page allows users to access vehicle status data and manipulate several vehicle controls, including turning on and off of headlights, opening and closing of convertible top, locking and unlocking of doors, and opening of trunk and fuel tank at the touch of a button thanks to the wireless applications.

Other Wireless Capabilities and Application Projects Include:

DG Bluetooth Prototype Application

DG's and ICRC's SmartTruck™ Prototype - Wireless Demonstration

SAIC and DG Joint Telematics Solution

DG and Lear Corporation's Interior Concept

DG Bluetooth Prototype Application
One of DG Technologies' most recent wireless applications project featured a demonstration of the DG Technologies Python, a multi-protocol analyzer, that converted wireless messages from Bluetooth wireless standard into serial data in order to perform several standard OBD II diagnostic functions at the 2002 SAE show. DG highlighted the consumer benefit with a WIN CE sample application running on an iPAQ, which will allow a user to monitor diagnostics on a vehicle using the J1850 (Class 2) vehicle network without the need for a PC or laptop. This demonstration exhibited the gateway leading into the future of wireless technology for DG Technologies, which may allow users to monitor diagnostic programs from a handheld iPAQ with a vehicle connection to a J1962, a passenger car standard.

DG's and ICRC's SmartTruck™ Prototype - Wireless Demonstration
DG Technologies at work as part of US Army, TACOM National Automotive Center display (MH-6) providing wireless connection to access several functions on ICRC SmartTruck prototype vehicle at the Auto Show 2002. ICRC SmartTruck™ prototype uses in-vehicle network port to provide access to diagnostics and body electronics. As the demonstration exhibited, the user can connect with network through this port using DG's wireless diagnostics application; which means that vehicle service centers will be able to remotely access and diagnose a problem on a vehicle The demonstration capabilities included controlling functions such as unlocking and locking of doors and turning on and off parking lamps. DG's wireless diagnostics application also has capabilities to monitor, retrieve and clear diagnostic codes for OBD II and SAE J1850 messages. DG's participation with ICRC's SmartTruck prototype is the beginning of several phrases of development in wireless diagnostics capabilities. Future releases include digital signal capabilities involving a gateway between I/O and the handheld via emerging products in our DG Gryphon product family, like the Gryphon-S3 and Gryphon 2.

SAIC and DG Joint Telematics Solution
Science Applications International Corporation (SAIC) along with DG exhibited how a telematics system can reliably and securely transmit test and measurement data to and from vehicles regardless of wireless communication protocols at SAE 2001. The demonstration used the DG Gryphon along with SAIC's in-vehicle telematics solution and its data center in Dayton, OH. Together, we were able to remotely monitor vehicle performance and global positioning data, which were compressed and encrypted into packets and sent via commercial wireless networks and/or wireless LAN to the data center. The SAIC telematics system supports bi-directional data communication, store-and-forward operations for delayed transmissions, remote configuration of vehicle instrumentation, and remote control vehicle functions (i.e. horn, lights, and door locks, engine controls, ignition, etc.). SAIC showcased its telematics solution that has been installed and tested on selected Ford and GM passenger cars and SUVs, while DG exhibited Gryphon as a powerful, cost-effective solution for accessing vehicle data remotely, that is unaffected by constraints of vehicle location.

DG and Lear Corporation's Interior Concept
At SAE 1999, DG exhibited in two demonstrations of helping customers connect to their cars to access functions. In the Lear Corporation booth, DG provided touch-screen connections to several functions on the TransG interior concept. The demonstration exhibited how a car owner could connect to a vehicle network both safely and securely with the network through this port using DG's CarConnect system-Ethernet-based network adapter paired with .off-the-shelf. technology-a PC, cellular modem, and optional Global Positioning System (GPS) DG's CarConnect concept system accessed functions on a Jaguar XK8 sports car via a wireless connection. The demonstration exhibited how the CarConnect system provided an intelligent gateway between a standard PC and a vehicle's electronic systems. A wireless cellular phone connection allows remote interaction between consumer functions already available on their vehicles. Demonstrated features at SAE exhibit included arming and disarming of car alarms, remote notification, (via email or pager) of breaking attempts, and closing of windows.
