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 forairbag 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.
