Hardware in the Loop-Simulation (HIL)

HIL applications are an extension of the sensor simulation. Several, even different Simulyzer boxes are linked and synchronized. In this way, for example, all sensors of different types belonging to an airbag system can be synchronized to generate data streams against an ECU.

Simple application

HIL in practice

Often up to 6 PSI5 simulators (or more) plus several SPI simulators are operated together. For coordination there is a superordinate configuration that determines which Simulyzers are used, which signal tracks are used by which Simulyzers and which detailed configurations with the bus parameters are to be used. Using this superordinate configuration, the API is very easy to use and is limited to about 4 calls to be made. A continuous control of the sensor signals is also possible.

An example of use

A typical application is the validation of triggering algorithms in airbag control units. The SQUIB box can be used to detect the activation (time, power) of the airbag igniters. Our HiL solution is also suitable for testing vehicle dynamics algorithms.

  • Time-synchronized playback of signal runs in combination of multiple different Simulyzer boxes. Example: 6 PSI5-Simulyzer plus 2 SPI-Simulyzer

  • Use of signal runs out of csv-files or out of user specific data bases

  • Integration into complete vehicle simulation
