Embodiment Construction

[0110] In order to fully express the purpose, technical solutions and advantages of the present invention, the embodiments of the present invention will be described in detail with reference to the following drawings and implementation examples. In order to fully understand, the specific implementation examples described here are only used to explain the present invention, and are not limited to the present invention.

[0111] The effectiveness of the method is verified by applying the lag comprehensive correction method proposed by the present invention to the follow-up visual driving simulator system. The follow-up visual driving simulator system is mainly composed of visual system 4, cockpit system 5, motion platform system 6 and sound system 7, such as figure 1 As shown, the lag comprehensive correction method is composed of a vehicle state acquisition module 1, a vehicle state estimation module 2, an integrated correction module 3. The integrated correction module 3 includes...

Abstract

The invention provides a follow-up visual vehicle driving simulator lag integration correction method and belongs to the driving simulator field. A vehicle state acquisition module, a vehicle state estimation module and an integration correction module are included. The method is characterized by collecting a vehicle state calculated by a vehicle dynamics model in real time; through noise removing processing, acquiring instantaneous low frequency data of vehicle motion; according to lag time of each execution system, determining longest time calculated by a prediction method module; through calculation, acquiring a vehicle state time sequence of a further moment; and selecting vehicle states corresponding to different time points for each execution system of a simulator. A condition that a single system and single signal independence correction cause repetitive calculation of a physical quantity and an incoordination phenomenon of a visual sense, hearing, a sense of touch and a body feeling is avoided; driving comfortableness of the simulator is increased; and response consistency of different systems is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of driving simulator application, and in particular relates to a method for comprehensively correcting the lag of a follow-up visual automobile driving simulator. Background technique [0002] Follow-up visual car driving simulator has become an indispensable tool for vehicle chassis development, advanced on-board electronic control system verification, driver behavior characteristics research, smart car control logic verification, connected car development, and smart road design. Applying the car driving simulator to participate in the development of car products can achieve a safer, more efficient and more economical development process. [0003] Follow-up visual car driving simulator is a kind of driver-in-the-loop virtual simulation environment. The virtual driving environment is constructed through digital methods, and the car responds to reconstruct the realistic driving scene. The working process of the fol...
