Test system and method for automated testing of at least two simultaneously with the control devices connected to the test system as well as control devices - connection - and control devices - switching unit for use in such a test system

摘要

According to the invention, a test system (2) for the automatic testing of at least two simultaneously to the test system connected control devices, comprises a control - computer (4), on the model of the - data to be tested for the control devices (40, 44) and, for a test sequence with a plurality of test steps, the control device - control data, as well as reference data for control unit - output signals are stored; a surrounding - simulations - computer (12), the with the control computer (4) is connected and a - / output - interface (16) for outputting of model - test signals and / or of control - test signals and for receiving control unit - output signals; wherein the surrounding - simulations - computer (12) is designed in such a way that a test sequence can be carried out with a plurality of test steps, in that the ambient - simulations - computer (12) from the of the control - computer (4) received model - data and control unit - control data model - test signals and / or control - test signals are generated and over its a - / output - interface outputs (16); and in that the ambient - simulations - computer (12) via its a - / output - interface (16) received control unit - output signals with reference data for control unit - output signals; wherein a separate control devices - connection - - - switching and control unit (20) is provided, comprising a test signal - interface (22), a switchable - interface (24), at least two control unit - connection - interfaces (42, 46), and at least one switch (32); the test signal - interface (22) with which a - / output - interface (16) of the ambient - simulations - computer (12) is connected; the switching range that is - interface (24) - with the control computer (4) is connected; and - of the control computer (4) and the at least one switch (32) of the control units - connection - - - switching and control unit (20) are designed in such a way that, after the carrying out a test flow with a plurality of test steps for a connected control unit (40, 44) of the control - computer (4) a switching signal to the control devices - connection - - - switching and control unit (20), and at least one switch (32) switches in such a way that the test signal - interface (22) with the control unit - connection - interface (46) of a second connected control unit (44) is connected.
