METHOD FOR PROVIDING A REAL-TIME SIMULATION FOR CONTROL UNIT DEVELOPMENT AND SIMULATOR FOR CONTROL UNIT DEVELOPMENT

摘要

A method for providing a real-time simulation (6) for the ECU development, wherein the real-time simulation (6) simulates a controller or an environment of a controller or a combination of a controller and an environment of the controller, wherein the real-time simulation (6) co-simulates a real-time-capable partial simulation (10) and a non-real-time capable partial simulation (12) interacting with the real-time capable partial simulation, the real-time-capable partial simulation (10) and the non-real-time partial simulation (12) being used to communicate simulation data (Se0, Sn0, Se1, Sn1, Se2, Sn2, Se3, Sn3, Se4, Sn4, Se5, Sn5), the real-time-capable partial simulation (10) having a first simulation time (te) corresponding to the real time, and the non-real-time-capable partial simulation (12) having a coupled to the first simulation time, at the beginning of real-time simulation with the first simulation The method comprises the following steps: (a) on the part of the real-time capable sub-simulation (10), checking whether the non-real-time-capable sub-simulation (12) has calculated simulation data for an upcoming macro-simulation step has provided; (b) if the non real-time capable sub-simulation (12) has completed computed simulation data (Sn2) for the upcoming macro-simulation step and provided the real time-capable sub-simulation (10), using the computed simulation data (Sn2) for the upcoming macro-simulation step in the real-time capable partial simulation (10); (c) if the non-real time partial simulation (12) has not completed computed simulation data for the upcoming macro simulation step and provided the real time partial simulation (10), generating estimated simulation data (Sg3) for the upcoming macro simulation step; (d) setting the second simulation time to the first simulation time after completion of the calculation of simulation data not provided in time (Sn3).
