Embodiment Construction

[0014] Such as figure 1 , The embodiment of the present invention shown in 2 is composed of four parts: a vehicle dynamics model, a real vehicle (22), a visual simulation system, and a driving information collection system.

[0015] The real vehicle (22) is used as the basic platform, and the operating environment provided is completely consistent with that of conventional vehicles. The performance of the real vehicle (22) is consistent with that of conventional vehicles of the same type, and can be used for outdoor experiments. The front wheels of the real vehicle (22) are placed on On the freely rotatable tray (14), the actual steering manipulation is approximately simulated, which is convenient for the driver's steering manipulation.

[0016] According to the basic requirements of driving simulation, a vehicle dynamics model for real-time vehicle simulation is established, which includes body model, engine model, tire model and brake model. Using this model, the simulation...

Abstract

The Semi-physical driving fatigue vision simulation system platform belongs to the technical field of driving vision simulation system platform. The invention comprises a vehicle dynamic model, a real vehicle (22), a vision simulation system and a driving information collecting system; with virtual reality as a basis, the technologies of interactive simulation, computer imaging and sensors are employed; the real vehicle (22) is in normal driving state and detects a research platform of driving fatigue state information in an all-round way; the vision simulation system comprises a work station (1) and a vision displaying device; the work station (1) resolves the vehicle dynamic model according to sensor signals of a driving information collecting system, generates and sends a dynamic driving scene to the vision displaying device; the driving information system comprises a driving parameter collecting subsystem, a video collecting subsystem, a physiology detecting subsystem and the like, which are respectively used to carry out all-round detection of characteristic information reflecting driving fatigue such as driving behavior, facial expression, body movement and physiological parameters of drivers. The invention is mainly applicable to experimental studies on the driving fatigue.

Description

technical field [0001] The invention relates to a driving scene simulation system platform. The device is suitable for implementing driving fatigue experiments, can provide a real driving manipulation space and a realistic driving environment, and realizes comprehensive detection of characteristic information reflecting driving fatigue. Background technique [0002] Driver fatigue driving is an important cause of traffic fatal accidents. Traffic accident statistics in many countries show that traffic accidents caused by fatigue driving account for 15% of personal injury accidents and more than 20% of fatal accidents, and 20-30% of commercial transport vehicle accidents in the United States and Europe are related to fatigue factors. Therefore, the research on driving fatigue detection has become a key field in the research of traffic safety technology in all countries in the world. Carrying out fatigue driving tests on actual roads has great risks, and fatigue driving tests...
