Embodiment approach 1

[0019]

[0020] Hereinafter, an embodiment of the present disclosure will be described using the drawings. figure 1 It is a diagram showing an example of the schematic configuration of the short-range wireless communication system 100 to which the present disclosure is applied. Such as figure 1 As shown, the short-range wireless communication system 100 includes a short-range wireless communication device 1, a mobile terminal 2a, and a mobile terminal 2b installed in a vehicle A.

[0021] The mobile terminal 2a and the mobile terminal 2b are mobile terminals such as a multifunctional mobile phone that a user can carry and carry. The mobile terminal 2a is located in the compartment of the vehicle A, and the mobile terminal 2b is located in a location away from the vehicle A, such as an indoor of the building B. As an example, the mobile terminal 2a and the mobile terminal 2b are the same mobile terminal except for the difference in positions relative to the short-range wireless co...

Deformed example 1

[0062] In the first embodiment, a configuration in which the communication range of the wireless communication unit 11 is changed in two stages of a wider communication range and a narrower communication range is shown, but it is not necessarily limited to this. For example, it may be configured such that the communication range of the wireless communication unit 11 is divided into a plurality of stages more than two stages and changed step by step (hereinafter, modification 1).

[0063] Hereinafter, this modification 1 will be described using the drawings. In addition, for convenience of description, in the description of this modification 1 and later, members having the same functions as the members shown in the figures used in the description so far are given the same reference numerals, and the description thereof will be omitted. The short-distance wireless communication device 1 of Modification 1 is the same as the short-distance wireless communication device 1 of the first...

Deformed example 2

[0075] In addition, unlike Modification 1, in the case where the communication range of the wireless communication unit 11 is gradually narrowed, the communication range may be gradually reduced every time a constant time elapses. Narrowing gradually.

Abstract

The invention provides an on-vehicle device that is provided with a wireless communication unit (11, 11a) for communicating and connecting with a portable terminal positioned in a communication range to implement wireless communication and that performs services using the wireless communication implemented by the wireless communication unit. The on-vehicle device is provided with: a parking determination unit (19) which determines whether the vehicle is parked; and a communication-range changing unit (20, 20a) which, in cases when the parking determination unit has determined that the vehicle is parked, sets the communication range of the wireless communication unit so as to be narrower than before the parking determination unit determined that the vehicle is parked.

Description

[0001] This application claims the priority of Japanese Application No. 2015-45149 filed on March 6, 2015, and uses all the contents here. Technical field [0002] The present disclosure relates to a vehicle-mounted device that performs wireless communication with a mobile terminal. Background technique [0003] As disclosed in Patent Document 1, there is known a technology that uses a mobile terminal carried by a user to communicate with an in-vehicle device installed in a vehicle, and the user receives various services such as hands-free calls. Generally speaking, if the mobile terminal is in the communication range, the in-vehicle device that performs wireless communication with the mobile terminal performs a communication connection with the mobile terminal for service, and if the mobile terminal is out of the communication range, the communication connection is cut off to end the service. [0004] Patent Document 1: Japanese Patent Application Publication No. 2014-130566 [0005...
