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.

Vehicle Drive
Simulator press release.
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.
