For example, the “MercedesMe connect” system from Mercedes-Benz offers many services such as accident management, breakdown and maintenance management, remote vehicle diagnostics, and remote services for customers alongside the emergency call function (“Mercedes-Benz eCall”) required by law. The voice and data connections of these types of telematics services rely on a telematics control unit in the vehicle, which is also referred to as a connectivity module. The current generation of this module is based on a telecommunications module that can tap into 2G, 3G, and 4G mobile-communications networks. The vehicle uses these to establish a connection and access data (e.g., traffic updates, infotainment services) from the internet. A permanently installed eSIM chip is provided to identify the vehicle in the network. How an in-vehicle emergency call (eCall) works Automated driving Functional safety and security through automated driving with dependable electronics Thanks to the infrastructure and interconnection with other vehicles, automated cars can detect dangerous situations ahead much sooner and drive more predictively. The first generation of vehicles that satisfies automation level 3 of the internationally accepted six-level scale is already being launched onto the market today. In order for it to weave in and out of urban traffic with a high level of automation, a vehicle needs to possess a number of essential abilities: It must perceive its surroundings, using the information obtained in this way to draw the right conclusions and react appropriately. Automated vehicles are equipped with a range of different sensors used for environmental recognition, from ultrasound, radar, and lidar sensors through to video systems. The information from these sensors—combined through “sensor fusion”—supplies a precise, reliable, and practically all-encompassing picture of the surroundings. This is expanded on using information supplied by other vehicles or by the road infrastructure itself. To this end, it is connected via a number of communications channels, from dedicated automotive WLANs to 5G mobile-communications networks. High-performance microcontrollers and processors are needed to process the barrage of data supplied by the sensors. Not only do these need to process information in real time wherever possible; they also need to satisfy the most demanding standards and requirements for security and functional safety. After all, their decisions are crucial for the vehicle’s safe operation. Spotlight on dependability Cybersecurity The volume of data to be transferred and processed is seeing exponential growth alongside the increase in vehicle connectivity and system complexity. Integrated payment methods used to pay parking fees or tolls, for example, demand a reliable flow of transaction data. Yet external access to a vehicle via connection to the cloud also increases the risk of hacker attacks substantially. Car manufacturers therefore need to ensure that information is processed securely and protected against third-party access and manipulation. At the same time, data protection needs to be maintained for drivers. Through a combination of hardware components like microcontrollers with integrated hardware security modules, SIM cards, and dedicated security controllers with appropriate software packages, the required protection mechanisms and associated costs can be adjusted and precisely matched to the security requirements of a specific application in a smart vehicle. Smart mobility with proven security solutions Monitoring vital signs A smart sensor monitors drivers’ health A modern car’s senses not only face outward; they can keep one eye on the driver, too. The VitalCaare solution from Caaresys is just one example: The system monitors passengers’ vital signs, including their breathing rate, heart rate, and also the variability of the latter. The driver’s state (e.g., stress or tiredness) can be monitored in this way, and the driver warned accordingly. The system uses 24 GHz radar technology and can be installed anywhere in the vehicle, whether in the seat, dashboard, roof console, roof lining, or rear-view mirror. Infotainment Multifaceted in-vehicle entertainment Cars’ infotainment systems have become multifaceted experiences in their own right. For today’s customers, smart user interfaces like touch screens, precise voice recognition, and powerful gesture recognition are all decisive factors when it comes to choosing which new vehicle to buy. Uninterrupted 24/7 connectivity is absolutely essential these days. This is made possible by wireless connections in the vehicle (mobile communications, Wi-Fi, and Bluetooth). The fact that more and more consumer devices like smartphones, tablets, and notebooks support USB-C and USB-PD (where “PD” stands for “power delivery”) means that demand is also growing for these connections in cars. The USB-C standard was approved in fall of 2014 and proved an instant triumph due to its small form factor and integration of user-friendly connections and cables, which enable multiple data transfer protocols to be used. Furthermore, in terms of supplying power, it facilitates charging processes at up to 100 W; an enormous improvement over the 7.5 W rating of earlier standards. Rear-seat entertainment systems with USB-C connections for DisplayPort video can therefore be connected with one or more screens to show videos, enabling content to be streamed from smartphones, tablets, and notebooks.
