Embodiment 1
[0069] Using Simulink to automatically model the establishment of 3 motor parts with the same properties as an example to illustrate the present invention, the steps are as follows:
[0070] C1. Build the motor part original part model template file under the Simulink platform. The motor part original part model template file is named "mot_M". The motor part original part model template file includes: input and output port signals, parameter signals, and input and output port signal names Named according to "component name_port name_port attribute", for example, the motor component input voltage port signal name is "mot_volt_in", and the parameter signal name is named according to "component name_parameter name_parameter attribute", such as the motor quality parameter signal name is " mot_mass_static";
[0071] C2. Use the special field to mark "_modify" the input and output port signals and parameter signals that need to be modified when creating the motor component target mo...

The invention provides an automatic signal modeling method for components with the same attribute of a vehicle. The method comprises the following steps: developing a template library; defining an original part model template file name; any special field is used for marking; obtaining a target part model template file; checking and verifying the target component model template file; obtaining a modified target part model template file; checking and verifying the modified target part model template file; a target model file is obtained, and modeling of a component model with the same attribute is completed; repeating the steps to obtain N component models with the same attribute; and finishing modeling. According to the automatic signal modeling method for the same-attribute parts of the vehicle, the problem of automatic modeling of the same-attribute parts in the building process of a virtual simulation model of the vehicle is solved. The original component model template file is used for generating specific target component models with the same attributes according to the steps, manual copying and modifying operation is avoided, modeling errors are reduced to the maximum extent, and simulation modeling efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the field of vehicle modeling and simulation, and in particular relates to a signal automatic modeling method for components with the same attributes of a vehicle. Background technique [0002] At present, vehicle virtual simulation technology is an important development tool in the early stage of automobile research and development, and it plays an active role in reducing vehicle costs and increasing efficiency. The core of vehicle virtual simulation technology is to build a component simulation model that restores the actual performance of the vehicle as much as possible. The simulation model is the mapping of the actual physical configuration of the vehicle. In the process of developing a vehicle simulation platform, if there are multiple components with the same properties in the vehicle, in the process of using these components to build a vehicle model, the accuracy of the component properties, signal properties, and param...
