Microautobox III helps meet connectivity requirements in electric car development

A high number of channels and an extended range of bus and network interfaces are key to dspace’s Microautobox III in-vehicle prototyping system aimed at meeting connectivity requirements in the development of self-driving and electrically powered cars. The addition of the new DS1521 I/O board suits the system to communication-intensive developments using centralised E/E architecture.

Typical applications for the Microautobox III with the DS1521 bus and network board include intelligent gateways, running supervisory controllers to control other engine control units in real time via buses and networks, and designing central control units with service-based ethernet communication.

To address these applications, the DS1521 bus and network board provides eight control area network with flexible data-rate channels, three automotive ethernet ports (100/1000BASE-T1), two flexray connectors (A/B), three local interconnect network channels, and additional universal asynchronous receiver-transmitter, digital, and analogue interfaces.

This prototyping system can also be equipped with two DS1521 boards, which results in doubling the number of the above-mentioned interfaces for those applications that are particularly communication intensive. A combination using other Microautobox I/O boards is also possible.

The system is configured using the Configurationdesk implementation software, including the integrated bus manager. This allows for configuring the bus communication on the basis of the latest standards and protocols, such as Autosar (ARXML), Fobex, DBC, or LDF.

For integration into an existing vehicle electrical system, current Autosar features such as secure onboard communication, end-to-end protection, and global time synchronisation are also supported on all relevant bus systems, including service-based ethernet communication.

A comprehensive extension framework is available for project-specific adaptations which can be integrated and implemented by dspace.

dspace provides simulation and test solutions for developing networked, autonomous, and electrically powered vehicles. Automotive manufacturers and their suppliers in particular use the company’s end-to-end solution range to test the software and hardware components of their new vehicles long well before a new
