Buick Enclave: Vehicle Data Collection andEvent 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 so equipped, 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. If your vehicle is equipped with StabiliTrak®, steering performance, including yaw rate, steering wheel angle, and lateral acceleration, is also recorded. 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 confidentiality is to be maintained
and need is shown, or
• share summary data which is not tied to a
specific vehicle with non-GM organizations
for research purposes.
Others, such as law enforcement, may have access to the special equipment that can read the information if they have access to the vehicle or the device that stores the data.
If your vehicle has OnStar®, please check the OnStar® subscription service agreement or manual for information on its operations and data collection.
