Embodiment Construction
[0045] figure 1 A simulation device 2 is shown, which in the present case is an HIL simulator 2 . The HIL simulator 2 has a physical interface 4 through which external devices can be connected to the HIL simulator 2 . exist figure 1 In , the controller 8 is connected to the physical interface 4 . exist figure 1 In the example shown, the controller 8 is a motor controller, which is designed to control a motor of a motor vehicle. HIL simulator 2 is designed to test motor controller 8 .
[0046] The HIL simulator 2 includes a real-time simulation 6 of the technical system. exist figure 1 In our example, Real-Time Simulation 6 is a combined model of the motor and transmission mechanism. The real-time simulation 6 can also be called the environment simulation of the controller 8 because it simulates the operating environment of the controller 8 , ie at least a part of the components related to the controller 8 in actual operation. The real-time simulation 6 exists in the fo...

The present invention relates to a method for providing real-time simulation for controller development, the real-time simulation comprising co-simulation of real-time partial simulation and non-real-time partial simulation, the real-time partial simulation having a first simulation time corresponding to real-time and the non-real-time part simulation has a virtual second simulation time. The method comprises the steps of: when the non-real-time partial simulation has completed the calculated simulation data for the upcoming macro simulation step and provides for the real-time partial simulation, in the real-time partial simulation, the calculated simulation data is used for the incoming macro simulation step; when the non-real-time partial simulation does not complete the calculated simulation data for the upcoming macro simulation step and provides for the real-time partial simulation, estimated simulation data is generated for the upcoming macro simulation step; after completing thecalculation of the simulation data that is not provided in time, the second simulation time is adjusted to the first simulation time.
Description
technical field [0001] The invention relates to the development of controllers for controlling technical systems such as motors or brakes, for example in the automotive or aerospace industry. The invention relates in particular to simulation means used during the development of controllers. Background technique [0002] Controller development has become a highly complex process. Therefore, new controllers or new control functions should be tested as early as possible in the development process in order to check general functionality and predetermine further development directions. Towards the end of the development process it is important to test an already highly developed controller as thoroughly as possible, so that necessary modifications can be made based on the test results before the controller is put into service or series production, so that it can be used in any future operation. All cases work as expected. [0003] So-called hardware-in-the-loop simulators (HIL...
