驾驶员通过视觉机能从交通环境中获得80％以上的交通信息,并通过大脑指挥手脚等运动器官操纵汽车行驶,处理一切情况,保证行车安全。然而,在车辆行驶中,随着车速的加快,视觉机能随之降低,视界随之变窄,视力随之减弱,这种现象决不容忽视。 一、速度越高人眼视界越小 正常情况下,人眼视界的视角一般为200度,在左右100度范围内的物体都能感觉到它的存在位置,但
The driver receives more than 80% of the traffic information from the traffic environment through the visual function, and controls the vehicle through the organs such as the hands and feet under the control of the brain to handle all situations and ensure traffic safety. However, as the vehicle speeds up, the visual function decreases with the speed of the vehicle, the field of vision narrows and the visual acuity weakens. This phenomenon can not be ignored. First, the higher the speed of the human eye field of smaller normal Under normal circumstances, the human visual field of view is generally 200 degrees, in the range of 100 degrees around the object can feel its existence, but
