Abstract: A computer-based system and method for assigning at least one signal of a symbol-based program to at least one I/O functionality of a target hardware unit is provided. A modeling tool has a symbol-based program with the signal that is to be assigned. The signal to be assigned of the symbol-based program and the at least one I/O functionality of the target hardware unit are specified in a configuration tool. Using the modeling tool, an I/O functionality of the target hardware unit is assigned in the symbol-based program to the signal that is to be assigned. A signal assignment information item is generated in the modeling tool from this assignment. The signal assignment information item is transmitted from the modeling tool to the configuration tool, and the configuration tool takes over the assignment to the I/O functionality of the target hardware unit of the signal to be assigned of the symbol-based program according to the signal assignment information item.

Abstract: A test bench (1) is described and shown for testing a distance sensor (2) operating with electromagnetic waves, wherein the distance sensor (2) to be tested comprises at least one sensor radiating element (3a) for radiating a transmission signal (4) and a sensor receiving element (3b) for receiving a reflection signal, with a receptacle (5) for holding the distance sensor (2) to be tested, with an at least partially movable connecting member (6, 6m, 6s) in the radiation area of a distance sensor (2) held in the receptacle (5), with at least one test bench receiving element (7) held in the connecting member (6, 6m, 6s) for receiving a transmission signal (4) radiated by the sensor radiating element (3a), and with at least one test bench radiating element (8) held in the connecting member (6) for radiating a test bench transmitting signal (9) as a simulated reflection signal.
A reliable environment simulation, in particular for the testing of multiple input-multiple output distance sensors (2) is achieved in that at least one test bench receiving element (7, 7a, 7b) and one test bench radiating element (8, 8a, 8b) are arranged together in a movable part (6m) of the connecting member (6).

Abstract: A computer-implemented method for calculation and output of control pulses by a control unit having a first computing unit and a second computing unit, wherein the control pulses are output by the control unit to an internal combustion engine. The calculation of the control pulses is optimized in that the first computing unit calculates a control pulse pattern with triggering information for multiple future control pulses at a first sampling rate using prior state data of the engine, and transmits the calculated control pulse pattern to the second computing unit, that the second computing unit at a second sampling rate that is greater than the first sampling rate of the first computing unit corrects the triggering information of the control pulses that are currently to be output using current state data of the engine, and that control pulses are output to the engine based on the corrected triggering information.
