ROUTE PLANNING DEVICE, ROUTE PLANNING METHOD, AND ROUTE PLANNING SYSTEM

A management server according to the present invention comprises: a position confirmation unit which confirms a via point of a vehicle and the position of the vehicle; an objective function determination unit which determines an objective function; a vehicle assessment unit which assesses for each of a plurality of vehicles whether the vehicle is a moving vehicle that is currently moving or is scheduled to move or a stopped vehicle that is currently stopped, on the basis of information collected from the plurality of vehicles; and a computation allocation determination unit which determines that a computational process for planning a route for a moving vehicle moving by consuming energy supplied to a drive source from an energy storage unit is to be allocated to a stopped vehicle able to compute the objective function, and which, via a server-side communication unit, directs a controller of the stopped vehicle to perform the computation. 管理服务器具备：位置确认部，其确认车辆的经由地点以及车辆的位置；目的函数决定部，其决定目的函数；车辆判断部，其基于从多个车辆收集的信息来判断各个
