TE Automotive /// Driving the Data-Fueled Future Page 4 With the evolution towards advanced driver assist safety systems and the greater number of automated driving functions within the vehicle, high-speed data transmis- sion lanes in vehicles are becoming increasingly relevant to the safety of the vehicle. This means that new design features for vehicle components are required and that vehicle OEMs must consider the limitations of physical channel properties during the definition of the architec- ture and the selection of the communication protocol. Vehicle-to-occupant connections. An important connec- tion to consider is the connection between human and machine. Whether providing information to the driver, entertainment to a passenger, or seamless integration with personal devices, the connection between occupants and the vehicle itself is becoming essential. Via tomor- row's digital cockpit, drivers and occupants alike will be provided experiences specifically tailored for them. Seat and mirror settings, music presets, navigation settings, and address book information, for example, can automat- ically follow the driver from one vehicle to the next. For passengers, streaming service accounts and wi-fi settings can be at the ready from car to car. Some examples of vehicle-to-occupant connections include: • WLAN • Bluetooth • USB • WiFi • Displays AUTOMOTIVE DATA CONNECTIVITY CHALLENGES AND REQUIREMENTS Evolving data connectivity specifications and require- ments are challenging, and automotive OEMs and sup- pliers are working together to address these vehicle chal- lenges. There is a high variety of data messaging strategies (functional layer) and transmission protocols (physical layer) not only between vehicle manufacturers, but even in a single vehicle. Wireless connections (antennas) come in many varieties depending upon the frequency and pro- tocol of the interface. Wired connections can be differen- tial twisted pair, coaxial, shielded, unshielded, etc. They can even be optical. Connections must be fast. In-vehicle communications architectures are driving towards speeds up to 12 GB per second. ACES-driven applications, with their ever-increas- ing computing speeds needed for critical decision-mak- ing, are demanding high bandwidth, high volume, and low latency communication channels. Connections must be robust and reliable. Data communi- cation must be flawless, even in an all-electric high-power environment. Data links must meet rigorous electromag- netic compatibility (EMC) requirements, ensuring they do not inadvertently radiate unwanted emissions nor are sus- ceptible to inadvertent electromagnetic fields. In-vehicle communication channels will be subjected to temperature and vibration extremes. Connections must be small and fit the communications architecture. They must support miniaturization and weight reduction approaches approaches driven by car manufacturers and system suppliers. As electronics con- tinue to shrink while functionality grows, connectors can- not and should not dictate the package size of the elec- tronics. Whether for a distributed architecture approach or for a centralized one, the connectivity solution must fit the approach. New architectures incorporating high- speed computing clusters supporting signal processing for applications based on sensor fusion will have increas- ingly challenging requirements for data communications within vehicles.
