A new or improved algorithm is to be integrated in an ECU. This involves creating a model in Simulink and generating the CANape target code via the Real-Time Workshop. After compiling and linking, a DLL is available to you that runs in CANape.
Parameters from the ECU are sent to CANape in an event-driven way via standard mechanisms (DAQ) of the XCP calibration protocol. The signals serve as input parameters to the model. The output data of the computation are synchronously written back to the ECU via CANape and the XCP mechanism (STIM).
Bypassing does not incur any additional hardware costs, since the necessary standard PC is available to every user. Although a Windows operating system does not represent a classic real-time environment, it can be used to achieve very short round-trip times of under 2ms:
