In the present invention, an advanced map database 43 stored in a server device 4 includes pulse type information that is setting information for detecting a landmark using a lidar 2. By sending request information D1 including host-vehicle position information to the server device 4, a vehicle-mounted device 1 receives response information D2 including pulse-type information corresponding to a landmark around the host-vehicle position and controls the lidar 2 on the basis of the received pulse-type information.
