The invention discloses a method for calculating the distance between a passenger and a vehicle. A vehicle-mounted terminal on the vehicle, a smart phone carried by a passenger and provided with an APP, and a background server are included. The smart phone and the vehicle-mounted terminal respectively send passenger information containing the longitude and latitude of the passenger and vehicle information containing the longitude and latitude of the vehicle to the background server, and the background server requires to calculate the distance between the passenger and the vehicle according toa specified method. According to the method, the passenger in the range near the vehicle or the vehicle in the range near the passenger is found out, only the distance between the passenger and the nearby vehicle is calculated, the calculated amount of the system is remarkably reduced, and the method is obviously reasonable and effective and is beneficial to system operation.
本发明公开了一种计算乘客与车辆之间距离的方法,包括车辆上随车的车载终端、由乘客携带安装APP的智能手机和后台服务器;所述智能手机和所述车载终端分别将包含所述乘客的经纬度的乘客信息和包含所述车辆的经纬度的车辆信息发送至所述后台服务器,所述后台服务器要求按照规定的方法计算所述乘客与所述车辆之间的距离。本发明先找出车辆附近范围内的乘客或者乘客附近范围内的车辆,只计算该乘客与附近车辆的距离,系统计算量将显著减少,这种方法显然合理、有效,有利于系统营运。
