HiL (Hardware in the Loop) is used in the automotive sector among other things for tests of single or multiple coupled electronic systems, such as control devices or systems of infotainment electronics. The input signals of the systems, to be tested, are generated with special simulation models, that simulate the real environment of the systems.
The output signals of the systems are compared with expected signal values to identify deviations or errors. Due to the use of simulation models and the automation of the evaluation of the output signals of the systems, the number of required tests in the real environment (e.g. in the car) is significantly reduced. At the same time the development time of the electronic systems is shortened.
jBEAM can be used to control and monitor a HiL test bench.
