Advanced driver assistance systems

Advanced driver assistance systems (ADAS) are additional electronic systems in motor vehicles supporting the driver in certain driving situations. They often focus on safety aspects or on increased driving convenience.

Automated driving

Automated driving describes the autonomous operation of a computer-controlled vehicle in road traffic. An autonomous vehicle is one that navigates independently (that is, without support from human beings). Such vehicles use various sensors to gather information about their surroundings, from which they can determine their position, navigate towards a destination, and avoid collisions on the way.

Broad-based strategy

The broad-based strategy is the German automotive industry’s strategy for raising efficiency.

Business electronics

Business electronics refers to electronic devices used in companies, such as printers, large format displays and large format projectors.

Car-to-car communication

This form of connected communication is the exchange of information between two vehicles that warn each other of obstacles on the roadway, a change in the road surface, or other hazards. (See also car-to-X communication.)

Car-to-infrastructure communication

This term refers to wireless communication between vehicles and components of the infrastructure. These components may be intelligent traffic signs, or nodes in the cellular network, which can be used for establishing communication with the Internet, infotainment platforms or carmakers.

Car-to-X communication

Pronounced “car to many,” this denotes the exchange of information between vehicles, other means of transport, the infrastructure, traffic management centers and various Internet applications. In car-to-X communication the car both sends and receives data, while other players also receive and process the information.

Cloud computing

Cloud computing replaces local data storage with storage in a “cloud” that can be accessed via the Internet.


A community on the Internet is a virtual group of Internet users. Usually the members have interests in common, communicate via the Internet, and make their knowledge available for use in the community.

Consumer electronics

Consumer electronics is a general term covering electronic devices used for entertainment. They include PCs and mobile telephones, along with MP3 players, DVD players and digital cameras.

eCall (short for “emergency call”) is a system that the European Union is currently planning for motor vehicles, which will call the emergency services automatically. Devices installed in the vehicle will automatically report a road traffic accident to the European emergency telephone number 112, and faster activation of the rescue services will help reduce the number of deaths on the roads.

Extended floating car data

Extended floating car data (XFCD) is, as the name suggests, a development of floating car data (see FCD below). Compared with FCD, XFCD uses additional data from all advanced driver assistance systems.

Floating car data

Floating car data (FCD) is a system using data from vehicles currently being driven. FCD collects data about a vehicle’s movement and location while it is in motion and when it is stationary, e.g. in congestion, at traffic lights or in waiting areas. A data set contains at least a time stamp and the location’s coordinates. In floating car data, cars become mobile sensors or software agents. (See also Extended floating car data.)

HMI stands for “human-machine interface.” It enables a human being to interact with a machine. To deliver any benefit, this type of interface must be adapted to the user’s needs and abilities, and be intuitively comprehensible.

HUD technology

HUD stands for “head up display” and refers to a display of important information within the user’s field of vision.

ICT stands for “information and communication technology.”

LTE (Long Term Evolution) is a new mobile telephony standard that will further accelerate the expansion of mobile Internet use in particular. LTE allows data transfer rates of between 100 and 300 Mbps, and can be used to rapidly download HD movies to a car, for example – even while the vehicle is in motion.

Real-time data

Real-time data are data that are collected continuously and made available for immediate processing. They include information about vehicles such as current fuel consumption, braking behavior and temperature, and information on the current level of traffic or the state of the road ahead.

A smartphone is a cell phone allowing more computer features and connectivity. Additional programs (called “apps”) are available for most of today’s smartphones enabling users to install individual new functions of their choice.

Telematics is a combination of telecommunication and information technology. It is the means of linking at least two information systems using a telecommunication system and a special form of data processing.

The Universal Mobile Telecommunications System (UMTS) is a third generation (3G) mobile telephony standard enabling far higher data transfer rates (up to 21 Mbps with HSPA+, otherwise max. 384 kbps) than GSM, the second generation (2G) mobile telephony standard (up to 220 kbps for EDGE; otherwise max. 55 kbps for GPRS).

Vehicle app / App

The term “app” applies in general to any form of application software. Nowadays, however, it is used mostly to refer to applications for smartphones and tablet computers, which are acquired from an online shop integrated into the operating system and can therefore be installed directly on the smartphone. In the automotive context there are apps for motorists to aid navigation or display parking ticket vending machines, for example.

A wireless local area network (WLAN) denotes a local radio network, usually one that operates to a specification from the IEEE-802.11 family. In some countries the term Wi-Fi is commonly used for this narrower meaning, although it is frequently regarded as synonymous.
