Automatic modeling method for user-defined vehicle controller

An automatic modeling method for a user-defined vehicle controller, comprising the following steps:

• S1:
• selecting and configuring, on a graphical user interface (GUI) of a vehicle simulation platform, all component models of a vehicle model except a vehicle controller, and completing component connection and parameter configuration;
• S2:
• generating a component model description file and a component model parameter description file based on the component models configured in step S1;
• S3:
• summarizing input signals and output signals of the component models based on the component model description file generated in step S2, and obtaining an input signal set and an output signal set;
• S4:
• calculating a difference set between the input signal set and the output signal set obtained in step S3, wherein the difference set is an unmatched demand input signal set in all the component models of the vehicle model except the vehicle controller selected in step S1, and the unmatched demand input signal set is defined as an output signal set of the user-defined vehicle controller;
• S5:
• taking the output signal set in step S4 as an alternative input signal set of the user-defined vehicle controller, and selecting, by a user, one or more signals in the input signal set as input signals of the user-defined vehicle controller;
• S6:
• summarizing, based on the component model parameter description file generated in step S2, parameter names in the component model parameter description file into a parameter set for building the user-defined vehicle controller, and selecting, by the user, one or more parameters in the parameter set as demand parameters of the user-defined vehicle controller;
• S7:
• creating a port model template on the vehicle simulation platform based on steps S4 and S5, creating a control policy model template based on the demand parameters of the user-defined vehicle controller selected in step S6 and an actual need of the user, and completing first creation of the user-defined vehicle controller based on the port model template and the control policy model template;
• and
• S8:
• checking, after the first creation of the user-defined vehicle controller is completed, input signal configuration of the user-defined vehicle controller before each overall vehicle simulation covering all components.
