Demo Description

Gateway demo with the following main components:

  • Tata Elxsi’s AUTOSAR Classic platform & Green Hills Software’s µ-velOSity have been integrated on the R-Car S4, to develop a Software-Defined Vehicle (SDV) gateway platform.
  • This demo shows the forwarding of CAN data to an Ethernet service-based communication by using SOME/IP (Scalable Service-Oriented Middleware over IP) and Service Discovery protocol.
  • The gateway enables the communication between traditional CAN-based networks and the new service-based Ethernet networks.
GHS $ TATA Demo Description

To achieve the above, Tata Elxsi AUTOSAR Classic has been integrated with Green Hills Software’s µ-velOSity running on the R52 of the R-Car S4:

  • Configuration & integration of AUTOSAR BSW comprising of CAN, Ethernet, Mode Management, SOME/IP, SD (Service Discovery), RTE (Run-Time Environment) modules
  • Configuration & integration of µ-velOSity as an AUTOSAR compliant operating system in the BSW via the eZyConfig tool
  • Configuration & integration of Renesas SDK for R52 MCAL (Microcontroller Abstraction Layer) drivers
  • Sample service-based applications running over the RTE
