The invention discloses a park low-speed electric unmanned vehicle pedestrian warning method and system based on fuzzy control. The park low-speed electric unmanned vehicle pedestrian warning method comprises the steps that S1, state information of surrounding pedestrians, vehicles and the environment at the current moment is acquired; s2, calculating the minimum longitudinal distance, the minimum transverse distance, the longitudinal relative speed and the maximum deceleration of the vehicle between each person and the vehicle in the dangerous area; S3, respectively setting corresponding fuzzy sets for the minimum longitudinal distance, the minimum transverse distance, the longitudinal relative speed and the maximum deceleration of the vehicle calculated in the step S2; corresponding membership function fuzzification is set according to the fuzzy set, and finally the longitudinal risk degree, the transverse risk degree and the comprehensive risk degree Di are obtained through a preset fuzzy rule; s4, performing ambiguity resolution according to the environment background sound level intensity and the environment illumination intensity, calculating the sound level intensity and frequency of the early warning prompt tone and the light illumination intensity of the early warning lamp, and performing acousto-optic early warning; and S5, returning to the step S1 until the vehicle flames out or the early warning prompt switch is manually turned off.

    本发明公开了一种基于模糊控制的园区低速电动无人车行人警示方法及系统,其包括:S1,获取当前时刻的周围行人、自车及环境的状态信息;S2,计算危险区域内每个人与车辆之间的最小纵向距离最小横向距离纵向相对速度和车辆最大减速度S3,将步骤S2计算得到的最小纵向距离最小横向距离纵向相对速度和车辆最大减速度分别设置相应的模糊集,再根据模糊集设置相应的隶属函数模糊化,最后利用预设的模糊规则获取纵向危险度横向危险度和综合危险度Di;S4,根据环境背景声级强度、环境光照强度解模糊,计算预警提示音声级强度、频率和预警灯灯光光照强度,进行声光预警;S5,返回步骤S1,直至车辆熄火或人为关闭预警提示开关。
