[0061] In a possible implementation, the vehicle dynamic performance simulation device further includes a simulation detection module. Figure 5 , is a schematic diagram of the structure of another vehicle dynamic performance simulation device provided in an embodiment of the present application. Figure 1On the basis of the above, a simulation detection module 501 is also shown. Specifically, the simulation detection module is used to detect the operating state parameters of the power simulation module performing the simulation task, and generate a simulation report corresponding to the simulation task. Among them, the communication interface of the simulation detection module is connected to the virtual bus.

[0072] In an embodiment of the present application, after the simulation task is determined, the vehicle power architecture corresponding to the simulation task is determined based on the simulation task.

[0073] In practical applications, after the vehicle power architecture is determined, in order to ensure the accuracy of the vehicle power performance simulation test, the simulation device of the vehicle power performance is tested first. When the test results meet expectations, the relevant simulation tasks are simulated.

[0074] Specifically, in one possible implementation, after the vehicle power architecture is determined, the test simulation task is first input; then, according to the test simulation task, the simulation test report corresponding to the test simulation task is determined; finally, the simulation test report corresponding to the test simulation task and the actual test report corresponding to the test simulation task are matched, and when the simulation test report corresponding to the test simulation task and the actual test report corresponding to the test simulation task match, the simulation task is tested according to the determined vehicle power architecture, and the simulation test report is output. It can be understood that the simulation task will be tested only when the simulation test report corresponding to the test simulation task and the actual test report corresponding to the test simulation task match, which improves the accuracy of the simulation test of the vehicle power performance to a certain extent.
