HiL-Simulation for Airbag ECU

To generate a complete HIL simulation for an airbag control unit, the internal acceleration sensor signals of the control unit (SPI) and the peripheral acceleration and pressure sensor signals (PSI5) must be connected. Also the ignition timing can be measured and analyzed by using the SQUIB box. Furthermore, a PC system connected to the simulators via a USB port/network is used for data processing.

Often up to 6 or more PSI5-Simulyzer are operated together with several SPI-Simulyzer. For coordination there is a superordinate configuration, which determines which Simulyzer is used, which signal traces are used by which Simulyzer and which detailed configurations are to be used with the bus parameters. By using the superordinate configuration, the operation of the API is very simple. A continuous control of the sensor signals can also be made.
