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), toprovide 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.
