<p>PROBLEM TO BE SOLVED: To search for a time series pattern of an optimum state of own vehicle until a prescribed time elapses by allowing a change in speed.SOLUTION: Vehicle information including position information is acquired by a vehicle information acquisition part 22 with respect to each of an own vehicle and the other vehicle, and a plurality of kinds of vehicle states including each of the nodes showing an acceleration state, a deceleration state, a constant speed state, and a traffic lane change state is made available by an optimal solution retrieval part 24 with respect to each time after the predetermined time elapses, each node is connected in a time series manner, each of the time series patterns of the vehicle state of the own vehicle is expressed, and the time series pattern of the optimum vehicle state of the own vehicle is searched according to a cost calculated based on the relative position for the speed and the acceleration of the own vehicle and the other vehicle in times corresponding to the node which is acquired based on the vehicle information shown by the node and each vehicle information of the own vehicle and the other vehicle acquired by the vehicle information acquisition means with respect to each node.</p> |
