From Sensors to Smart Antenna

The central components of a connected car strategy are the networking of systems in the car, a connection to a mobile infrastructure in the vehicle, the ability to connect to the Internet, and the way in which vehicular systems connect with their surroundings. EBV has many years of expertise in each of these areas and can assist its customers by providing in-depth expertise, strong partners and the right products. 

Networking of Vehicle Components: Many cars today are equipped with field bus systems such as MOST, LIN, CAN, and FlexRay. They network the systems in the vehicle and ensure fault-tolerant, time-triggered communication between electronic components, often between sensors, actuators and control computers. In this way, they often meet tough, real-time requirements. They must also directly and securely implement steering or braking commands, for example.

Sensors are an integral part of the range of topics related to connected cars. So for example, radar and camera modules can supply data to intelligently analyse a situation, which the connected car then uses in its assistance systems to actively support the driver. EBV has traditionally been strong in this area. 

In-Car – Connection to the mobile infrastructure: Smart phones are used as an interface to the Internet in many connected car applications. In order to connect to a connected car internal system, various different methods can be used, such as Bluetooth / Low Energy (BLE), WiFi, USB/USB-C, NFC, MHL, or even MirrorLink. Radio technologies and wireless charging modules in particular promise a high degree of convenience when it comes to the interaction between smartphones and vehicle systems. 

Car2X – Connect to the Surroundings and the Internet: A connected car can communicate with its surroundings via a mobile network or WLAN. However, previous WLAN technologies were primarily designed for stationary operation and the dynamics of a moving car can pose problems. The consequence was that radio signals could not be reliably transferred in Car2X communication. The new WLAN standard IEEE 802.11 p (USA: Dedicated Short Range Communications, DSRC; EU: IST-G5) addresses these very issues. 

There are also many requirements linked to mobile communications as well: the future mobile communications standard 5G will benefit from transfer speeds of up to 10 GBit/s. As vehicles will be defined as the endpoint in the sequence, each vehicle will ideally utilise the full bandwidth. This requires the car to have the ability to handle particularly fast data processing, in addition to being equipped with high-quality cabling.

The external antenna plays a crucial role in this, having evolved over the years from a little metal rod to an intelligent communication centre. These smart antenna can undertake an increasing number of tasks in the car, from being an RF transmitter and receiver of technology for mobile communications and WLAN, navigation and entertainment, including digital data processing, right through to embedded security. 

EBV helps businesses to develop and implement intelligent approaches, which make use of smart antenna as an integral part of their connected car concept. With its RF vertical segment, EBV Elektronik is perfectly positioned and can recommend the appropriate technology produced by manufacturer-independent developers, from chips via software to antenna. In combination with powerful security technologies, customers can already lay the foundation for a comprehensive IT security concept in terms of RF technology.
