为了研究驾驶人心理因素在信息认知过程中的作用机理,根据模糊数学和拓扑心理学原理,以数名驾驶人的驾驶信息为样本,分析了道路空间距离对驾驶人驾驶心理的影响程度,研究了在道路空间距离变化规律形成过程中,驾驶人心理量生成基础和变化原因。当实际道路空间距离分别为25、75、125m,车辆速度分别为0、20、40、60、80、100km/h时,进行了道路空间距离判识试验,并分别计算了在不同条件下的隶属函数模型。计算结果表明:随着车速的增大,驾驶人的判识距离与道路实际空间距离的差值不断减小,下降速率不断增大;当车速大于40km/h时,随着道路实际空间距离的增大,判识距离下降速率逐渐减小;随着道路实际空间距离的减小,驾驶人心理疆域边界接触允许时间也在不断变小,碰撞风险增大。
In order to study the mechanism of drivers ’psychological factors in cognitive process of information, according to fuzzy mathematics and topological psychology, taking several drivers’ driving information as a sample, this paper analyzes the influence degree of road distance on driver’s driving psychology, The basis and causes of the driver’s psychological quantity formation are studied during the formation of the law of the distance variation of the road. When the actual road distance is 25,75 and 125m respectively and the vehicle speed is 0, 20, 40, 60, 80 and 100km / h respectively, the road space distance test is carried out. And under different conditions Membership function model. The calculation results show that as the vehicle speed increases, the difference between the driver’s recognition distance and the actual road space distance decreases and the descending rate increases. When the vehicle speed exceeds 40km / h, As the distance of the actual road in the road decreases, the allowable contact time of driver’s psychological frontier boundaries is also getting smaller and the collision risk increases.
