CANoe.IP as a development tool for Car2x applications
In analyzing Car2x communication between vehicles and with the roadside infrastructure, CANoe.IP now also supports the wireless interface IEEE 802.11p. The tool simulates traffic scenarios with vehicles and infrastructure and simplifies development and testing of Car2x communication.Typical tasks encountered in Car2x projects include monitoring communication, analyzing the protocols used and displaying transmitted values. To create CANoe.IP simulations of road side units (RSU) or car communication units (CCU/OBU), WLAN frames are sent by either the Ethernet Packet Builder or the integrated CAPL programming language. CANoe users can access real or simulated internal vehicle buses and ECUs with time-synchronous support of Ethernet and the wireless interface in parallel with CAN, LIN, FlexRay and MOST. Proprietary protocols are also supported; this may involve operating OEM-specific applications via the wireless interface or communication between internal vehicle application units and the communication module via Ethernet.
Option GPS extends CANoe.IP by offering visualization of the vehicle's location on an electronic map. This makes it much easier to interpret the logged measurement data. Complex or difficult to reproduce driving situations can be run in laboratory simulations to test and optimize algorithms for Car2x functions.
The communication modules used are LinkBirds from the company NEC Electronics. They produce the wireless interface per IEEE 802.11p with an implemented Car2x Stack per requirements of the "CAR 2 CAR Communication Consortium". An application developed by Vector handles the exchange of information and commands between LinkBird and CANoe.IP. Modules of other manufacturers may be integrated in the same way.
