Even today, drivers can use their smartphones to locate their vehicles or easily navigate to the nearest free parking space. Smartphones often use V2Cloud applications for this purpose. These applications exchange the required data, such as the vehicle position, free parking spaces, etc., with Internet services via a mobile radio network, prepare the data, and make it available to the driver. The combination of 5G and edge computing, which promises high data throughputs and low latencies, has the potential to allow for completely new applications, such as for sharing high-definition sensor data and computing power with vehicles and infrastructure. This can enable cooperative perception, swarm intelligence based on shared AI, or real-time traffic optimization to make automated driving more comfortable, ecofriendly, and safer. The applications for connected cars will be integrated more closely with the vehicle, which leads to high demand on simulation and test environment in order to validate the entire processing chain. The unparalleled integration of the Anritsu Radio Communication Test Station for LTE and 5G with the dSPACE SCALEXIO HIL system empowers early development and end-to-end validation of cutting-edge applications for connected and cooperative automated driving, without being depended on local 5G test site and infrastructure. The Anritsu Test Station provides a realistic test network that consists of base stations (radio access network) and a core network. The emulator can be connected directly to the cloud or a back-end server and exchanges data between the edge computing service and the tested application in the vehicle. You can use wires or antennas to connect the emulator to the communication unit. For the latter, the radio signals must be appropriately shielded.
You can control the mobile network emulator from the HIL simulator using a Simulink blockset. This lets you reconfigure the mobile network to manipulate data throughput and latency, for example, and also supports mobility scenarios such as a handover (changing from one cell site to another). During a virtual test drive, the radio link is transferred from one base station to the next without losing the data link. Another frequent test case is path loss, where the radio signal becomes increasingly weaker or even breaks off completely during a drive.
