The input / output GUI 101 is used as an input unit for various parameters necessary for simulation processing and a change data input unit, and is also used as a display unit for simulation result data.

  Next, with reference to FIG. 2 and subsequent figures, a specific simulation process and parameter setting / changing process example executed in the simulation apparatus of the present invention will be described. Hereinafter, as an example of simulation processing executed in the simulation apparatus of the present invention, a simulation processing example in which simulation processing for driving driving of an automobile is integrated will be described.

  FIG. 2 is a diagram illustrating a correspondence between a plurality of simulation modules and input data as a parameter group input to each module in the simulation apparatus according to the embodiment of the present invention. FIG. 2 shows the input data 210 and the simulation execution unit 250. The input data 210 is data input from the input / output GUI 101 shown in FIG. For example, data stored in the database 105 constituted by a hard disk or the like is saved in a file format, and is data in which the name, value, and unit of each input parameter are recorded.

  The simulation process execution unit 250 corresponds to the simulation process execution unit 103 illustrated in FIG. The simulation processing execution unit 250 sets a plurality of simulation modules 251 to 254 that execute simulation processing based on different simulation processing programs, and executes simulation processing by parallel processing by each module. Intermediate data and result data are input / output between the modules.

  The driving operation simulation module 251 reads the input data 211 and executes a simulation processing program that predicts a driver's operation. The input data 211 includes parameters such as driver information such as driver age, road surface information, environmental information such as temperature, and target speed information.

  The driving operation simulation module 251 reads the input data 211 composed of these parameters, inputs the simulation data of the vehicle traveling state from the vehicle traveling simulation module 254 that is executing the processing in parallel, and reflects the input data. The driving operation simulation process for predicting the driver's operation is executed.

The input data 212 includes parameters of engine configuration information such as cylinder diameter and stroke, fuel type, and environmental information such as temperature.

  The combustion simulation module 252 reads the input data 212 composed of these parameters, and further inputs the simulation data of the operation information of the driver from the driving operation simulation module 251 that executes the processing in parallel to reflect the input data. While simulating combustion inside the engine, a combustion simulation process for calculating the driving force of the piston is executed.

  As shown in FIG. 2, in a complex simulation system configuration in which a plurality of simulation processing modules operate in parallel and input / output data to / from each other, for example, a simulation is performed when the temperature changes from 25 ° C. to 35 ° C. Suppose that comparison processing is performed. In this case, it is necessary to change the temperature parameter included in the input parameter from 25 ° C. to 35 ° C.

  When such a parameter change is performed, it is necessary to check whether or not the temperature data is included in the input data 211 to 214, and to change the input data only when it is included. If accurate change processing is not performed, simulation cannot be performed accurately. However, the temperature is included in a lot of input data, and it is complicated and error-prone to check all of them and change the input data.

  Therefore, in the simulation apparatus according to the present invention, a process of presenting the common parameter setting screen 300 as shown in FIG. 3 to the input / output GUI 101 under the control of the data control unit 102 is executed.

  The common parameter setting screen 300 shown in FIG. 3 will be described. The user inputs data to the extraction target data input unit 301, the character string input unit 302, and the parameter value input unit 303 in the common parameter setting screen 300 shown in FIG.

  In the parameter value input unit 303, the changed parameter value or a newly set parameter value is input. For example, when the temperature parameter is changed to 35 ° C., [35] is input to the parameter value input unit 303 as shown in the figure.

  The extraction target data input unit 301 inputs a category of data to be set or changed. In this case, the change target is a temperature parameter, and in order to extract the parameter name in which [temperature] is set as [parameter name], [parameter name] is input to the extraction target data input unit 301, and a character string In the input unit 302, a character string [temperature] is input. With this setting, input data including temperature as a parameter name is identified.

  The data control unit 102 shown in FIG. 1 executes a simulation module extraction process to which input data including air temperature as a parameter name is applied based on these input data. Specifically, among the input data 211 to 214 in FIG. 2, the input data 211, 212, and 214 are input data including temperature as a parameter name. Modules to which these input data are applied are a driving operation simulation module 251, a combustion simulation module 252, and a vehicle travel simulation module 254. The data control unit 102 generates a common parameter setting screen 300 that presents a list of these simulation modules on the extraction result display unit 311 shown in FIG. 3 and presents it on the input / output GUI 101. The display order of this list can be rearranged according to the accuracy of parameter change included in the input data, the order of simulation execution, and the like by the “Sort” menu.

  Here, three modules are modules that input “air temperature” as a parameter, but “air temperature” applied in the driving operation simulation module 251 is the temperature in the vehicle interior, and the indoor temperature is kept constant regardless of the outside air temperature by air conditioning. It is kept. Therefore, “combustion simulation” and “vehicle running simulation” are selected from the three modules displayed on the extraction result display unit 311. The selection is performed by checking the check unit 312.

  Further, by pressing the “apply” button 321, the numerical value of the temperature in the input parameters of “combustion simulation” and “vehicle running simulation” is changed from 25 to 35. These parameter changing processes are executed in the data control unit 102.

  In the common parameter setting screen 300 shown in FIG. 3, an all check button 313 is also prepared as a button for checking all the displayed modules at one time for easy operation.

  As described above, the extraction target data input unit 301 is set as an input unit for inputting a category of data to be changed. In the example described above, an example of processing when “parameter name” is input has been described. However, for example, “unit”, “numerical value” or the like is input as the category of data to be changed, and “° C.” “mm”, “60”, “45”, or the like is input to the character string input unit 302. Thus, it is possible to extract a parameter having a specified unit or to extract a parameter having a numerical value in a specified range.

For example,
In the extraction target data input unit 301, “unit”,
In the character string input section 302, “° C.”
If you enter
It becomes possible to discriminate a simulation module using nn ° C. as an input parameter. For example, in the configuration shown in FIG. 2, since the input data 211, 212, and 214 include “25 ° C.”, the driving operation simulation module 251 to which the input data 211, 212, and 214 are applied as in the above-described embodiment. Module lists of the combustion simulation module 252 and the vehicle travel simulation module 254 are displayed on the extraction result display unit 311.

For example,
In the extraction target data input unit 301, “numerical value”,
In the character string input section 302, “42”
If you enter
It is possible to determine a simulation module using 42 as an input parameter. For example, in the configuration shown in FIG. 2, since “42 years old” is included in the input data 211, a module list of the driving operation simulation module 251 to which the input data 211 is applied is displayed on the extraction result display unit 311.

  Next, with reference to FIG. 4, a sequence of processing executed in the simulation apparatus of the present invention will be described. In step S101, user input data, that is, change parameter information is input to the common parameter setting screen (see FIG. 3) presented on the input / output GUI 101. For example, as described with reference to FIG. 3, the extraction target, the character string, and the changed value data are input.

  In step S102, the data control unit 102 sets an extraction target corresponding to the input data as a search range, selects a simulation module having input data including a character string input to the extraction target, and presents it on the GUI. . For example, in the example described with reference to FIG. 3, a simulation module extraction process that applies input data including temperature as a parameter name is executed. In the example of FIG. 3, the driving operation simulation module 251, the combustion simulation module 252, and the vehicle travel simulation module 254 are selected and presented on the GUI.

  In step S103, the value of the changed parameter input by the user via the GUI and the applied module information of the changed parameter are input. In step S104, the changed parameter is input to the corresponding module of the simulation processing execution unit 104 to perform simulation processing. Execute.

  As described above, in the configuration of the present invention, the input screen for setting or changing the input parameter value for each simulation module is presented to the GUI unit, and the setting or changing schedule is scheduled based on the information input via the GUI unit. Since the process of selecting a module that can be used as an input value and presenting it to the GUI unit is executed, the user uses the parameter to be changed as the input value when performing the parameter changing process. Only by executing a process of selecting a parameter application module from the listed modules without investigating the module, a reliable parameter change is possible, and an efficient process is realized.
