Embodiment Construction

[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0020] Such as figure 1 As shown, the method for automatically importing vehicle parameters into the vehicle dynamics model includes: establishing an empty vehicle object instance, that is, no parameter data is filled in the vehicle object instance, and the structure of the vehicle object instance includes a system object instance and a subsystem object instance; Open and read the vehicle parameter file, first read the parameters of the current line, judge the system ownership of the currently read parameter, enter the system object instance of the system to which the current parameter belongs according to the system ownership, and then judge whether the parameter is subsystem data, and then determine whether the parameter ...

Abstract

The invention provides a method of automatically importing vehicle parameters into a vehicle dynamic model, belongs to the technical field of automobiles, and solves the problems that an existing manual entry way is very tedious and the disordered storage of the vehicle parameters makes manual entry more troublesome. The method of automatically importing the vehicle parameters into the vehicle dynamic model comprises the steps of building an empty vehicle object instance, wherein the vehicle object instance comprises a system object instance and a subsystem object instance, opening and reading a vehicle parameter file, and further reading all-level system parameter data read from the vehicle parameter file into the vehicle object instance; reading the vehicle object instance, and building a Carsim model and respectively loading the parameter data of the system object instance and the subsystem object instance read from the vehicle object instance into the Carsim model on by one. A tedious process of manually entering the vehicle parameters into the Carsim model one by one in a conventional method is avoided.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a method for automatically importing vehicle parameters into a vehicle dynamics model. Background technique [0002] With the development of vehicle dynamics simulation, vehicle dynamics models of different complexity have been produced. The vehicle dynamics model mainly studies the dynamic characteristics of vehicles under the action of various forces, and discusses these dynamic characteristics and their influence on vehicle performance. [0003] Among them, CarSim is a simulation software specially designed for vehicle dynamics. The CarSim model can simulate the response of the vehicle to the driver, road surface and aerodynamic input. It is mainly used to predict and simulate the handling stability, braking and smoothness of the vehicle. Performance, power and economy, and are widely used in the development of modern automotive control systems. CarSim can conveniently and ...
