Abstract
When a vehicle and a smartphone are in a second communication state, the vehicle can operate, and then if the vehicle and the smartphone are not in the second communication state for a predetermined time or longer, and if a main switch of the vehicle detects a predetermined operation, an emergency advertising is transmitted from the vehicle. Thereby, the smartphone can be used as a key that can receive the emergency information from the vehicle. By enabling the smartphone to be used as a key for the vehicle, it is possible to popularize a smartphone that can be used as a key for the vehicle.
