Telematics

DGE's automotive electronics system experience (analog I/O, vehicle bus, etc.) and familiarity with the OEM design cycle has been harnessed by a number of telematics providers.  We design the various vehicle interfaces and assist our customers with ECU integration into the OEM vehicle. 

Telematics Vehicle Bus Interfaces

Numerous telematics devices incorporate DGE's Vehicle Bus Interface designs.  Examples include:

  • Hughes Personal Assistance Safety and Security Module
  • Peiker Acustics Bluetooth Hand Free Phone Module
  • Garmin Navus GPS Module

Telematics Applications

In addtion to our vehicle bus intefaces, DGE has developed a number of telematics applications and subsystems which include analog I/O, serial data interfaces, a crash sensor simulator, and ipod software interfaces.

Telematics Test Systems

Our telematics test systems are “smart,” robust, programmable, expandable, and designed anticipate our customers' needs. Examples of our telematics testers include the following:

Vehicle Drive Simulator

Our Vehicle Drive Simulator is a PXI-based rack system which simulates all of the external I/O to a telematics ECU.  The user interface is a LabVIEW-based GUI which controls the following subsystems:

  • Vehicle Configuration Data
  • ECU Interface
  • GPS Interface
  • GSM Interface
  • Vehicle CAN Simulation
  • Vehicle Diagnostics
  • Multiple Power Supplies
  • Fault Insertion
  • Scripting
  • Logging

With the VDS, a user can load a configuration file which contains vehicle particulars, and simulate all drive related data including a GPS scenario and dead reckoning.  All vehicle network signals are modeled.  Faults may be inserted and ECU behaviors assessed.  The unit is capable of running scripts remotely.  All data may be logged.

Simple Benchtop Tester

DGE designed this unit to validate basic operation of a telematics ECU in a static environment.  The benchtop tester provides power, audio, and communications interfaces (including two CAN and multiple serial data).  It contains loads, breakouts, and controls for fault insertion.

The benchtop tester supplies inputs for external equipment such as a GPS simulator or a GSM antenna.  Combined with a PC running a custom vehicle CAN simulation, this unit can simulate most of the conditions that the telematics ECU will encounter in normal operating condtions. 

The benchtop tester may also function as an in-vehicle test tool (signal breakout box) allowing engineers to measure signals as well as insert faults into all of the ECU's I/O circuits while it is running in the vehicle environment.
