Abstract

The invention relates to a development car driving simulation method based on a rapid control prototype, and belongs to the technical field of simulated driving of a car. The method comprises the following steps of: firstly, building a software platform of a rapid control prototype device by a real-time kernel generated by a monitor computer, compiling and downloading a driving simulation model; secondly, calculating speeds and directions of all simulated vehicles and simultaneously sending a visual computer and the monitor computer after the rapid control prototype device receives a control signal of a driving simulator, and respectively generating a visual image and monitoring drive simulation process; finally, modifying the driving simulation model by a driving simulator or a developer according to a vehicle of the driving simulator and a performance requirement of an electric control system, repeating the driving simulator process until the requirement of the driving simulator or developer is met. The development car driving simulation method has the advantages that the development driving simulator is simplified; development cost is reduced, and the development car driving simulation method is suitable for a V-type development mode of the electric control system of the vehicle.

Description

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. Background technique [0002] At present, the basic structure of the developmental driving simulator is shown in Figure 1, including 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 and the vehicle ...
