Additional Data Recording Unique to
This Fuel Cell Vehicle
Because the Equinox Fuel Cell Vehicle is a market test
engineering development vehicle, it is designed to
record more data during its operation than is the case
with regular production vehicles. This additional
data is intended to help GM understand the vehicle
operating conditions and performance, including how the
fuel cell system performs during all types of driving.
Data is automatically collected by a computer-based
data acquisition system whenever the vehicle is turned
on. This data acquisition system can record
approximately 1700 variables every 10 milliseconds
from the fuel cell system and other vehicle system
controllers. The data includes such things as vehicle
speed, accelerator pedal position, power requested,
brake pedal position, drive motor actual power level, and
hydrogen fuel flow. These parameters are saved in a
digital file format and are periodically transferred
from the vehicle to a central computer where they may
be used for analysis to support improvements in the
design and operation of the fuel cell system and
the other vehicle systems. Some of this data may also
be combined with other information and included in
reports to the U.S. Department of Energy and other
federal or state agencies in connection with their support
of fuel cell vehicle demonstrations and development.
Your use of this vehicle may similarly provide experience
in dealing with hydrogen as a motor vehicle fuel,
including information useful to the development of global
codes and standards surrounding the use and storage
of hydrogen as a fuel for regular production vehicles.
Event Data Recorders
This vehicle has an Event Data Recorder (EDR). The
main purpose of an EDR is to record, in certain crash or
near crash-like situations, such as an airbag deployment
or hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems performed. The
EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time,
typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
•
How various systems in your vehicle were operating
•
Whether or not the driver and passenger safety
belts were buckled/fastened
•
How far, if at all, the driver was pressing the
accelerator and/or brake pedal
•
How fast the vehicle was traveling
