Problems solved by technology

The disadvantage of this approach is that the test model and the environment model are functionally dependent on each other, since the environment model has to be implemented through dedicated test model-related function calls (OPAL-RT Technologies Inc.: "RTLAB, Product Description, Detailed Characteristics, Typical application”; 2005)
This creates a significantly high overhead in the environment model and thus leads to a noticeable runtime disadvantage when the function of the test model is an "empty function"

Embodiment Construction

[0040] 1 to 6 illustrate certain aspects of the testing method of the present invention, the scheduling method of the present invention and the testing device of the present invention by means of different embodiments, respectively.

[0041] FIG. 1 shows a typical structure of a test environment for testing an electronic control system 1, which is suitable for carrying out the method of the invention. The electronic system under test 1 is here connected to the testing device 3 via a data channel 2 . The environment model 4 is calculated on the test device 3 , wherein the environment model 4 outputs the environment model data to the control system 1 through the test device 3 , and receives the control system data from the control system 1 through the data channel 2 to interact with the control system 1 .

[0042] The testing of the control system 1 by the test device 3 is basically carried out by influencing the environment model 4 executed on the test device 3 . To this end, ...

Abstract

A method for testing at least one electronic control system (1) is showed and described, wherein, the control system (1) connects with testing device(3) by a data channel (2), the testing device calculates at least one environmental model (4) which exports the environmental model data to the control system (1) by the testing device (3), receives the data of the control system from the control system on the data channel (2) and interacts with the control system (1). The method of the invention overcomes the fault of the existing method in the technology, which includes executing at least one test model (5) for influencing the environmental model (4) and / or calculating and / or electronic control system (1) of the environmental model (4), the test model (5) or these test models (5a, 5b) executed functionally independent of the environment model (4) and on a testing operation that is in synchronization with the environment model (4).

Description

technical field [0001] The invention relates to a method for testing at least one electronic control system, wherein the control system is connected via a data channel to a test device, at least one environment model is calculated on the test device, and the environment model is transferred to the environment model by the test device Data is output to the control system and interacts with the control system by receiving control system data from the control system on the data channel. Furthermore, the invention relates to a scheduling method for implementing at least one test model on a simulation computer, in which the first scheduler is activated on the basis of an external activation signal. Finally, the invention also relates to a test device for testing at least one electronic control system, wherein the test device is connected to the control system via a data channel, at least one environment model is calculated with the test device, and the environment model is calculat...
