Fig. 3 is a flowchart of a simulation method of a new energy vehicle energy management system provided in an embodiment of the present application, which is exemplified by applying the simulation method of the new energy vehicle energy management system to the embodiment, and the simulation method of the new energy vehicle energy management system may include the following steps:
step 301: the terminal respectively carries out model building on a control system, a transmission system and a heat management system in an energy management system of the new energy automobile through a first simulation application program, a second simulation application program and a third simulation application program to obtain a control model, a transmission system model and a heat management model.
As can be appreciated from FIG. 1 above, the first simulation application can be a MATLAB/SIMULINK application, the second simulation application can be a CRUISE application, and the third simulation application can be a KULI application. Therefore, the terminal can perform model building on the control system in the energy management system through the first simulation application program, namely the MATLAB/SIMULINK application program, so as to obtain a control module; carrying out model building on a transmission system in the energy management system through a second simulation application program, namely a CRUISE application program to obtain a transmission system model; and performing model building on the thermal management system through a third simulation application program, namely a KULI application program to obtain a thermal management model.
As an example, the terminal can build a control model in a first simulation application when receiving a first build instruction in the first simulation application, build a drive train model in a second simulation application when receiving a second build instruction in the second simulation application, and build a thermal management model in a third simulation application when receiving a third build instruction in the third simulation application.
In some embodiments, the terminal can build a control model, a drive train model and a thermal management model in a first simulation application program, a second simulation application program and a third simulation application program respectively when receiving a first build instruction, a second build instruction and a third build instruction, can also obtain the built control model, drive train model and thermal management model from a storage file when receiving a first obtain instruction, a second obtain instruction and a third obtain instruction respectively in the first simulation application program, the second simulation application program and the third simulation application program, and loads the obtained control model, drive train model and thermal management model into the first simulation application program, the second simulation application program and the third simulation application program respectively to complete building of the control model, the drive train model and the thermal management model.
It should be noted that the first building instruction and the first obtaining instruction are triggered when a user acts on the display interface of the first simulation application program through a specified operation, the second building instruction and the second obtaining instruction are triggered when the user acts on the display interface of the second simulation application program through a specified operation, the third building instruction and the third obtaining instruction are triggered when the user acts on the display interface of the third simulation application program through a specified operation, and the specified operation can be a click operation, a sliding operation, a voice operation, and the like.
Because the control system, the transmission system and the thermal management system in the energy management system comprise a plurality of subsystems, correspondingly, a plurality of models are respectively comprised in the control model, the transmission system model and the thermal management model. Therefore, the terminal respectively carries out model building on a control system, a transmission system and a thermal management system in the energy management system of the new energy automobile through the first simulation application program, the second simulation application program and the third simulation application program, and the operation of obtaining the control model, the transmission system model and the thermal management model comprises the following steps: building an energy management strategy model, an energy recovery control model, a gear shifting control model and a heat management control model in a first simulation application program to complete building of the control model; building a whole vehicle model, a high-voltage battery model, a high/low voltage power consumption model, a DC/DC model, a motor model, a gearbox model, a brake model, a tire model and a driver model in a second simulation application program to complete building of a transmission system model; and building a passenger compartment model, an air conditioner cooling/heating model, a battery heating/cooling model, an MCU (microprogrammed control unit) and a DC/DC (direct current/direct current) cooling model in a third simulation application program so as to complete the building of the thermal management model.
In some embodiments, the terminal respectively performs model building on a control system, a transmission system and a thermal management system in an energy management system of the new energy automobile through a first simulation application program, a second simulation application program and a third simulation application program, and before a control model, a transmission system model and a thermal management model are obtained, the terminal can also receive a first starting instruction, a second starting instruction and a third starting instruction, operate the first simulation application program according to the first starting instruction, operate the second simulation application program according to the second starting instruction, and operate the third simulation application program according to the third starting instruction.
It should be noted that the first start instruction can be triggered when the user acts on the identifier of the first simulation application displayed in the terminal through a specified operation. Similarly, the second start instruction can be triggered when the user acts on the identifier of the second simulation application program displayed in the terminal through a specified operation, and the third start instruction can be triggered when the user acts on the identifier of the third simulation application program displayed in the terminal through the specified operation. The identification of the first simulation application, the identification of the second simulation application, and the identification of the third simulation application can be image identifications and/or text identifications.
Step 302: the terminal associates the control model, the drive train model and the thermal management model in a first simulation application.
In order to calibrate the energy management system of the new energy management automobile, the terminal can perform correlation processing on the control model, the power train model and the thermal management model in a first simulation application program.
As an example, the operation of the terminal in the first simulation application to associate the control model, the powertrain model, and the thermal management model comprises: setting a first communication module in the second simulation application program, wherein the first communication module is used for enabling the second simulation application program to respectively communicate with the first simulation application program and the third simulation application program; setting a second communication module in the third simulation application program, wherein the second communication module is used for enabling the third simulation application program to be communicated with the first simulation application program and the second simulation application program respectively; setting a third communication module and a fourth communication module in the first simulation application program, wherein the third communication module is used for enabling the first simulation application program to communicate with the second simulation application program, and the fourth communication module is used for enabling the first simulation application program to communicate with the third simulation application program; and respectively carrying out data setting on the third communication module and the fourth communication module so as to realize the association of the control model, the transmission system model and the thermal management model.
In some embodiments, since the second emulation application can be a CRUISE application, the first communication module can be a CRUISE Interface module, which can serve as a joint emulation Interface to enable the second emulation application to communicate with the first emulation application and the third emulation application, respectively. Since the third simulation application can be a KULI application, the second communication module can be a plurality of COM objects that can act as joint simulation signal interaction interfaces to enable the third simulation application to communicate with the first simulation application and the second simulation application, respectively.
In some embodiments, since the first simulation application can be a MATLAB/simulation application, the third communication module can be a CRUISE module added in the first simulation application, the fourth communication module can be a KULI module added in the first simulation application, and the terminal can perform data setup on the third communication module and the fourth communication module, respectively, in order to enable the first simulation application to communicate with the second simulation application and the third simulation application.
As an example, the operation of the terminal performing data setting on the third communication module and the fourth communication module respectively includes: setting a solver, a file path of a drive train model and a simulation task identifier in a third communication module; and setting an application program version number, a file path of the thermal management model, input parameters and output parameters in the fourth communication module, wherein the application program version number is the version number of a third simulation application program with the thermal management model.
Because simulation results are different according to different simulation tasks and there may be multiple simulated tasks, the terminal can set a simulation task identifier in the third communication module in order to determine the requirement of each simulation.
It should be noted that the solver is a solver for solving the simulation task result. The simulation task identifier is used for identifying a simulation task, the simulation task identifier can be an identifier in at least one form of numbers, characters, letters and the like, and the simulation task can comprise a hectometer acceleration simulation task, an energy consumption simulation task and the like. The file path of the power train model is a file path in which the built power train model is stored, and the file path of the thermal management model is a file path in which the built thermal management model is stored.
In some embodiments, the input parameters can include motor speed, motor power, battery voltage, battery current, travel speed, and the like, and the output parameters include wheel center acceleration, driver seat rail acceleration, shock absorber speed, battery temperature, and the like.
In some embodiments, since some terminals may have different versions of simulation applications installed for the same simulation application, the fourth communication module further needs to set an application version number in order to successfully perform joint simulation.
As an example, before setting the application version number, the file path of the thermal management model, and the input parameter and the output parameter in the fourth communication module, the terminal can also determine the number of installed third simulation applications; when a plurality of third application programs are installed, executing the operation of setting the version number of the application program, the file path of the thermal management model, the input parameters and the output parameters in the fourth communication module; and when a third application program is installed, setting a file path, input parameters and output parameters of the thermal management model in the fourth communication module.
When a plurality of third simulation applications with different versions are installed, in order to smoothly perform joint simulation, the terminal needs to set an application version number of the third simulation application with the thermal management model built in the fourth communication module. When a third simulation application program is installed, the terminal can directly determine the installed third simulation application program as the application program with the thermal management model built because the third simulation application program with other versions does not exist, and therefore the version number of the application program does not need to be set in the fourth communication module.
Step 303: and the terminal simulates an energy management system of the new energy automobile through a control model, a transmission system model and a thermal management model in a first simulation application program.
In some embodiments, the first simulation application is capable of performing an integrated simulation of a control model, a powertrain model, and a thermal management model.
Because the first simulation application program is provided with the third communication module and the fourth communication module, and the second simulation application program is provided with the first communication module and the second communication module, when the simulation is carried out by the first simulation application program, the first simulation application program can communicate with the second simulation application program through the third communication module and the first communication module in the second simulation application program in the first simulation application program, so as to realize the joint simulation of the first simulation application program and the second simulation application program, and meanwhile, the terminal can communicate the first simulation application program with the third simulation application program through the fourth communication module and the second communication module in the first simulation application program, so as to realize the joint simulation of the first simulation application program and the third simulation application program, and further realizing the joint simulation of the first simulation application program, the second simulation application program and the third simulation application program.
Step 304: and the terminal displays the simulation result in the first simulation application program.
Because the terminal carries out analog simulation on the energy management system of the new energy automobile in the first simulation application program, after the simulation is finished, the terminal can display an analog simulation result in the first simulation application program.
The terminal can display the first simulation application program in at least one display mode such as text, graphics, and video.
In the embodiment of the application, the terminal can respectively model the simulation control system, the transmission system and the thermal management system in different simulation application programs, and couple a plurality of application programs to realize the joint simulation of the energy management system, so that the modeling time is saved, and the learning cost of the application programs is reduced.
