Method for simulating development type automobilism based on rapid control archetype

Abstract

The invention relates to a developing type automobile driving simulation method based on a rapid control prototype, which belongs to the technical field of automobile simulated driving. Firstly, a software platform for a rapid control prototyping device is established by utilizing a real-time kernel generated by a monitoring computer, and a driving simulation model is compiled and downloaded. Secondly, after the actuating signals of a driving simulator are received by the rapid control prototyping device, the speed and the direction of all simulated vehicles are calculated, and a scenery computer and the monitoring computer are transmitted simultaneously, and are respectively used for generating scenery images and monitoring the driving simulation process. Finally, a driving simulator or a developer modifies the driving simulation model according to the performance requirements of a vehicle and an electric control system used by the driving simulator, and repeats the driving simulation process till the requirements of the driving simulator or the developer are satisfied. The automobile driving simulation method has the advantages that the developing type driving simulator is simplified, the development cost is reduced, and the automobile driving simulation method is applied to the V-shaped development mode of the electrical control system of the vehicle.

Technical field: [0001] The invention relates to a developmental vehicle driving simulation method based on a rapid control prototype, belonging to the technical field of vehicle simulation driving. technical background: [0002] At present, the basic structure of the developmental driving simulator is as follows: figure 1 As shown, it includes the vehicle object (or the cockpit object), the vehicle motion simulation system, the scene generation system, the projection system, and the software and hardware interfaces between the systems. Among them, the vehicle motion simulation system is a key component of the entire driving simulator, and its hardware and software structure directly affects the technical level and application range of the entire driving simulator. The basic function of the system is to use the driver's operation signal transmitted from the cockpit to the simulation computer to calculate the motion state of the vehicle where the driving simulator is located...

Problems solved by technology

In addition, although the programming difficulty of vehicle motion simulation software based on C++ object-oriented programming technology is greatly simplified compared with assembly language, its ability to describe dynamic systems is far inferior to that of special modeling software such as Matlab / Simulink or Labview. It is also more complicated to modify

[0004] More importantly, with the increasing application of driving simulators in the development of new electronic control systems, the existing driving simulators, especially the original technical solutions of vehicle motion simulation systems, can no longer meet the requirements of rapid development of electronic control systems :

[0005] First, the vehicle motion simulation program of the existing driving simulator uses a flow programming language, which is not suitable for describing systems with many dynamic links such as vehicles and controllers, resulting in difficult modeling and low development efficiency;

[0006] Second, the existing driving simulators are not suitable for modeling roads, traffic flows or vehicles, and cannot quickly verify the application effect of electronic control systems on different roads, traffic flows and vehicles;

The existing driving simulator structure does not have the rapid prototyping function, which greatly limits the integration of driving simulation technology and V-shaped development mode, and hinders the development of electronic control systems, especially the development of driver assistance systems. application
