Prototyping system gets connectivity boost

New Products |
In the development of autonomous and electric cars, the connectivity requirements for in-vehicle prototyping systems are growing continuously. dSpace has equipped its MicroAutoBox III with an extended range of bus and network interfaces. With its high channel count, the new DS1521 variant is particularly suitable for communication-intensive developments that take into account the centralization of the E/E architecture.

Typical application examples for the MicroAutoBox III with the new DS1521 Bus and Network Board are, for example, intelligent gateways, the execution of supervisory controllers to control other ECUs in real time via buses and networks, as well as the design of central ECUs with service-based Ethernet communication. To address these use cases, the DS1521 Bus and Network Board offers eight CAN-FD channels, three automotive Ethernet ports (100/1000BASE-T1), two FlexRay connections (A/B), three LIN channels and additional UART, digital and analogue interfaces. For particularly communication-intensive applications, the system can also be equipped with two DS1521 boards, which leads to a doubling of the above-mentioned interfaces. A combination with further MicroAutoBox I/O boards is also possible.

The system is configured via the ConfigurationDesk implementation software, including the integrated Bus Manager. This allows bus communication to be configured based on the latest standards and protocols such as Autosar (ARXML), FIBEX, DBC or LDF. For integration into an existing on-board network, current Autosar features such as Secure Onboard Communication (SecOC), End-to-End Protection or Global Time Synchronisation (GTS) are also supported on all relevant bus systems including service-based Ethernet communication (SOME-IP).
