Vision is the main channel of driving information for driver, the visual perception model of virtual driver is the im-perative content of driving behavior modeling and simulation which affects the fidelity of driving behavior simulation. This pa-per introduced four methods of visual perception modeling. According to the feedback and selectivenees of vision, it estab-lished the visual perception model. It divided the visual perception into sensing and feeling and incorporated attention, memo-ry, driving fatigue and driving experience into the model, further analyzed their effects on visual perception. By simulating the virtual driver' s visual perception model, it validates the model which lay the foundation for driving behavior research.%视觉是驾驶员获得驾驶信息的主要通道,虚拟驾驶员的视觉感知模型是驾驶行为建模与仿真的重要内容,直接影响驾驶行为仿真的逼真度.介绍了四种视觉感知建模方法,根据视觉感知系统的反馈性和选择性,建立了视觉感知模型.在模型中,将视觉感知分为感觉和知觉两个过程,并引入了注意力、记忆力、驾驶疲劳和驾驶经验等因素,对每个因素进行分析.通过对虚拟驾驶员视觉感知模型的仿真实验,验证了该模型的可靠性和有效性,为驾驶行为研究提供了基础.
