The invention discloses a method and a system for planning a travel distance of a pure electric vehicle. The system comprises an Internet of Vehicles big data platform, a vehicle-mounted information service system module, a vehicle-mounted navigation system module and a battery management system module. The vehicle-mounted navigation system module is used for acquiring real-time position information of a vehicle and intersection information in a journey; the battery management system module is used for estimating real-time electric quantity information of the vehicle; the Internet of Vehicles big data platform is used for receiving vehicle data, calculating vehicle driving energy consumption information between two intersections on a vehicle driving path based on the vehicle data, calculating vehicle endurance mileage according to a navigation path, the vehicle driving energy consumption information and vehicle real-time electric quantity information, and transmitting the vehicle endurance mileage to the vehicle-mounted navigation system module; and the vehicle-mounted navigation system module is used for planning a charging site on the way according to the user travel plan, the vehicle endurance mileage and the charging pile resources when the vehicle endurance mileage does not meet the travel demand. According to the invention, the remaining mileage of the vehicle can be accurately estimated and the driving and charging travel of the user can be intelligently planned.

    本发明公开了一种纯电动汽车行程规划系统及方法,包括车联网大数据平台、车载信息服务系统模块、车载导航系统模块和电池管理系统模块;车载导航系统模块用于采集车辆实时位置信息和行程中路口信息;电池管理系统模块用于估算车辆实时电量信息;车联网大数据平台用于接收车辆数据,并基于各车辆数据计算出车辆行驶路径上两路口之间的车辆行驶能耗信息,以及根据导航路径、车辆行驶能耗信息及车辆实时电量信息计算出车辆续航里程并传输到车载导航系统模块;车载导航系统模块用于在车辆续航里程不满足行程需求时,根据用户行程规划、车辆续航里程和充电桩资源规划出途中充电地点。本发明能够准确估算出车辆剩余里程并智能规划用户的行驶及充电行程。
