Abstract: A hardware-in-the-loop (HiL) test system is for testing sensor fusion of an advance driver assistance system (ADAS). The ADAS includes a plurality of sensors and an electronic control unit (ECU) processing outputs of the sensors. The HiL test system includes a three-dimensional (3D) scenario simulator for generating drive scenarios including objects in a surrounding environment of a simulated vehicle, and a sensor target emulator for generating emulated sensors inputs to the plurality of sensors corresponding to the drive scenarios generated by the 3D scenario simulator. The sensor target emulator is configured to synchronize the emulated sensor inputs by interpolating a current location of the objects from parameters extracted from the drive scenarios.

Abstract: A coupling unit provides a signal path between at least two of: a first device under test (DUT), and first and second couplers. The first coupler is coupled to a signal analyzer. The second coupler is coupled to another DUT. Both couplers provide and receive signals to and from the coupling unit which includes first and second multiplexers. An output of the first DUT is coupled to a first input of the first multiplexer and to a first input of the first coupler. A first output of the first coupler is coupled to a second input of the first multiplexer. The output of the first multiplexer is coupled to the input of the second coupler. The output of the second coupler is coupled to a first input of the second multiplexer and to a second input of the first coupler. A second output of the first coupler is coupled to a second input of the second multiplexer. The output of the second multiplexer is coupled to an input of the first DUT.

Abstract: Disclosed is an event recognition unit (400) for recognizing and/or monitoring events on an information bus (120). The event recognition unit (400) comprises a sequencer state machine (140) for determining sequential dependencies of events, and a comparator (110) coupled to the information bus (120) and to the sequencer state machine (140). The comparator (110) provides a signal to the sequencer state machine (140) when a pattern on the information bus (120) matches with a pattern term of the comparator (110). The event recognition unit (400) further comprises an output loop (410, 420) from the sequencer state machine (140) to the comparator (110) for dynamically setting the pattern term of the comparator (110).
