Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if the
vehicle has the Anti-lock Brake System (ABS), to provide
anti-lock braking and to help the driver control the vehicle
in difficult driving situations. Some information may be
stored during regular operations to facilitate repair of
detected malfunctions; other information is stored only in
a crash event by computer systems, such as those
commonly called Event Data Recorders (EDR).
In a crash event, computer systems, such as the
airbag Sensing and Diagnostic Module (SDM) in your
vehicle may record information about the condition of the
vehicle and how it was operated, such as data related
to engine speed, brake application, throttle position,
vehicle speed, safety belt usage, airbag readiness,
airbag performance, and the severity of a collision.
This information has been used to improve vehicle
crash performance and may be used to improve crash
performance of future vehicles and driving safety.Unlike the data recorders on many airplanes, these
on-board systems do not record sounds, such as
conversation of vehicle occupants.
To read this information, special equipment is needed
and access to the vehicle or the device that stores
the data is required. GM will not access information
about a crash event or share it with others other than:
with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee,
in response to an official request of police or similar
government office,
as part of GM’s defense of litigation through the
discovery process, or
as required by law.
In addition, once GM collects or receives data, GM may:
use the data for GM research needs,
make it available for research where appropriate
condentiality is to be maintained and need is
shown, or
share summary data which is not tied to a specic
vehicle with non-GM organizations for research
purposes.
