Abstract: When it is not determined that the execution device has detected the in-cabin mobile terminal, the execution device changes the threshold by a specified amount. Thereafter, when it is determined that the execution device detects the in-cabin mobile terminal and the execution device does not detect the external mobile terminal, the execution device ends the setting of the threshold. When the execution device detects the external mobile terminal after the process of changing the threshold to be small, the execution device changes the threshold to be larger than the value after the threshold is changed to be small. The execution device terminates the setting of the threshold after greatly changing the threshold.
