BMW 3 Series 2020-2023 Operating data in vehicle User Manual

Operating data in the vehicle

Control units process data to operate the vehicle.

For example, this includes:

  • Status messages for the vehicle and its individual components, e.g., wheel rotational speed, wheel speed, deceleration, lateral acceleration, engaged safety belt indicator.
    ]Ambient conditions, e.g., temperature, rain sensor signals.

The processed data is only processed in the vehicle itself and generally volatile. The data is not stored beyond the operating period.
Electronic components, e.g. control units and vehicle keys, contain components for storing technical information. Information about the vehicle condition, component usage, maintenance recommendations, events or faults can be stored temporarily or permanently.

This information generally documents the state of a component, a module, a system, or the surrounding area, for instance:

  1. Operating states of system components, for instance, fill levels, tire pressure, and battery status.
  2. Malfunctions and faults in important system components, for instance, lights and brakes.
  3. Responses by the vehicle to special driving situations such as airbag deployment or engagement of the driving stability control systems.
  4. Information on vehicle-damaging events.

The data is required to perform the control unit functions. Furthermore, it also serves to detect and correct malfunctions and helps the vehicle manufacturer to optimize vehicle functions.
The majority of this data is stored temporarily and is only processed within the vehicle itself. In some circumstances, the vehicle may store some data for an additional but limited period of time.
When servicing, for instance during repairs, service processes, warranty cases, and quality assurance measures, this technical information can be read out from the vehicle together with the vehicle identification number.

A dealer’s service center or another qualified service center or repair shop can read out the information. The socket for OBD Onboard Diagnosis required by law in the vehicle is used to read out the data.
The data is collected, processed, and used by the relevant organizations in the service network. The data documents the technical conditions of the vehicle, which can be used to determine vehicle maintenance status, and facilitate quality improvement. Fault and event memories in the vehicle can be reset when a dealer’s service center or another qualified service center or repair shop performs repair or servicing work.

Data entry and data transmission into the vehicle

General information

Depending on the vehicle equipment, comfort and individual settings can be stored in the vehicle and modified or reset at any time.

For example, this includes:

  1. Settings for the seat and steering wheel positions.
  2. Chassis and climate control settings.

If necessary, data can be transferred to the entertainment and communication system of the vehicle, for instance via smartphone.

This includes the following depending on the respective equipment:

  1. Multimedia data such as music, films or photos for playback in an integrated multimedia system.
  2. Address book data for use in conjunction with an integrated hands-free system or an integrated navigation system.
  3. Entered navigation destinations.
  4. Data on the use of Internet services.

This data can be stored locally in the vehicle or is found on a device that has been connected to the vehicle, e.g., a smartphone, USB stick or MP3 player. If this data is stored in the vehicle, it can be deleted at any time. This data is only transmitted to third parties upon personal request as part of the use of online services. The transmission depends on the selected settings for the use of the services.

Incorporation of mobile devices

Depending on the vehicle equipment, mobile de‐vices connected to the vehicle, for instance smartphones, can be controlled via the vehicle control elements. The sound and picture from the mobile device can be played back and displayed through the multimedia system. Certain information is transferred to the mobile device at the same time. De‐pending on the type of incorporation, this includes, for instance position data and other general vehicle information. This optimizes the way in which selected apps, for instance navigation or music playback, work. There is no further interaction between the mobile device and the vehicle, such as active access to vehicle data. How the data will be processed further is deter‐mined by the provider of the particular app being used. The extent of the possible settings de‐pends on the respective app and the operating system of the mobile device.

General information

If the vehicle has a wireless network connection, this enables data to be exchanged between the vehicle and other systems. The wireless network connection is realized via an in-vehicle transmitter and receiver unit or via personal mobile devices brought into the vehicle, for instance smart‐phones. This wireless network connection enables ‘online functions’ to be used. These include online services and apps supplied by the vehicle manufacturer or by other providers.
