The Data Stored in The Vehicle

Event Data Recorder (EDR)

Event Data Recorder (EDR)

This vehicle is equipped with 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 air bag 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 depressing the accelerator and/or brake pedal; and,

  • How fast the vehicle was traveling.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur.

NOTE:

EDR data are recorded by your vehicle only if a non-trivial crash or near crash-like situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.

 

Mazda will not disclose any of the data recorded in an EDR to a third party unless:

  • A written agreement from the vehicle owner or the lessee is obtained

  • Officially requested by the police or other law enforcement authorities

  • Used as a defense for Mazda in a lawsuit, claim, or arbitration

  • Ordered by a judge or court

However, if necessary Mazda will:

  • Use the data for research on Mazda vehicle performance, including safety.

  • Disclose the data or the summarized data to a third party for research purposes without disclosing vehicle or owner identification information.

A computer that records vehicle data

A computer that records vehicle data

A computer is equipped that records data related to the vehicle control, operation, and the driving environment.

This computer records information such as the following.

  • Vehicle conditions such as engine speed and vehicle speed

  • Driving operation conditions such as accelerator and brake pedals, and information related to the environmental circumstances while driving the vehicle

  • Malfunction diagnosis information from on-vehicle computer

  • Information related to controls of other on-vehicle computers

The recorded information differs depending on the vehicle grade and the equipment.

Personal information (name, sex, age, and collision location) is not recorded.

Data handling

Data handling

Mazda and its contractors may obtain and use data recorded in EDRs and computers that record vehicle data for the purpose of vehicle malfunction diagnosis, research and development, and quality improvement.

Mazda will not disclose or provide any of the obtained data to a third party unless:

  • An agreement from the vehicle owner (agreements from lessor and lessee for leased vehicle) is obtained

  • Officially requested by the police or other law enforcement authorities

  • For statistical processing by a research institution after processing the data so that identification of the owner or the vehicle is impossible

  • Used as a defense for Mazda in a lawsuit, claim, or arbitration

  • Ordered by a judge or court
