The objective of the invention is to arrange that, when a plurality of mobile terminals are connected to, for example, a vehicle-mounted device, a to-be-controlled application be automatically determined in accordance with the connection history and the types of applications on the mobile terminals. A mobile terminal control apparatus (1) comprises: a device control unit (12) that detects whether a plurality of mobile terminals (2) are connected or not and that holds device information and application information into a connection history (11); and an application control unit (14) that determines, out of a plurality of applications held by connected mobile terminals (2), a to-be-controlled application on the basis of the connection history (11) and an application DB (13). In this way, when a plurality of mobile terminals are connected to a vehicle-mounted device, a to-be-controlled application can be automatically determined in accordance with the connection history and the types of applications on the mobile terminals.
