BMW 3 Series 2019-2021
The BMW 3 Series is a small luxury car that is known for its sporty performance, precise handling, and high-end features. The 2019–2021 BMW 3 Series cars build on its history while adding new features and improvements. The BMW 3 Series is known for its dynamic and athletic appearance. It has BMW’s signature kidney grille, sleek LED headlights, and a sculpted body. The 2019–2021 models have a modern and polished look, but they still have the same unique features that make the 3 Series so easy to recognise. The 2019–2021 BMW 3 Series came with a variety of engines, including both four-cylinder and six-cylinder setups. Most of these engines were turbocharged, which gave them a great mix of power and efficiency. The 3 Series had accurate handling and quick acceleration, which made it a fun car to drive in a wide range of situations.
Inside, the BMW 3 Series saloon was luxurious and made for the driver. To improve comfort and ease of use, high-quality materials, efficient design, and the latest technology were used. The 3 Series usually came with BMW’s iDrive infotainment system, which had a touchscreen display and offered easy-to-use settings, smartphone integration, and a variety of ways to connect. The 2019–2021 BMW 3 Series also put a lot of thought into safety and driver-help features. These often had advanced systems like forward collision warning, lane departure warning, blind-spot tracking, adaptive cruise control, and automatic emergency braking. These features were meant to make driving safer and give you peace of mind. Between the model years of 2019 and 2021, BMW made changes to the 3 Series to improve its performance, technology, and general driving experience. Improvements were made to the engine’s speed, the infotainment system was updated, and new driver-assistance features were added. For the most accurate and up-to-date information on the specific features, updates, and improvements of the 2019–2021 BMW 3 Series, I suggest calling a BMW dealership or visiting the official BMW website. They will know the most up-to-date information about each BMW 3 Series model year and trim level during that time.
Electronic control devices are installed in the vehicle. Electronic control units process data they receive from vehicle sensors, self-generate or exchange with each other. Some control units are necessary for the vehicle to function safely or provide assistance during driving, for instance, driver assistance systems. Furthermore, control units facilitate comfort or infotainment functions. Information about stored or exchanged data can be requested from the manufacturer of the vehicle, in a separate booklet, for example.
Each vehicle is marked with a unique vehicle identification number. Depending on the country, the vehicle owner can be identified with the vehicle identification number, license plate, and corresponding authorities. In addition, there are other options to track data collected in the vehicle to the driver or vehicle owner, for instance, via the ConnectedDrive account that is used.
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 is 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’s 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:
- ▷ Operating states of system components, for instance, fill levels, tire pressure, and battery status.
▷ Malfunctions and faults in important system components, for instance, lights and brakes.
▷ Responses by the vehicle to special driving situations such as airbag deployment or engagement of the driving stability control systems.
▷ 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
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:
- Settings for the seat and steering wheel positions.
- 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:
- Multimedia data such as music, films, or photos for playback in an integrated multimedia system.
- Address book data for use in conjunction with an integrated hands-free system or an integrated navigation system.
- Entered navigation destinations.
- 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 devices connected to the vehicle, for instance, smartphones, can be controlled via vehicle control elements.
The sound and pictures 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. Depending 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 determined by the provider of the particular app being used. The extent of the possible settings depends on the respective app and the operating system of the mobile device.
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, smartphones. 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.
Services from the vehicle manufacturer
Where online services from the vehicle manufacturer are concerned, the corresponding functions are described in the appropriate place, for instance, the Owner’s Manual or the manufacturer’s website. The relevant legal information pertaining to data protection may also be found on the manufacturer’s website. Personal data may be used to perform online services. Data is exchanged over a secure connection, for instance with the IT systems of the vehicle manufacturer intended for this purpose. Any collection, processing, and use of personal data above and beyond that needed to provide the services must always be based on legal permission, contractual arrangement, or consent. It is also possible to activate or deactivate the data connection as a whole. That is, with the exception of functions and services required by law such as Assist systems.
