Benefits of technology

[0027]According to embodiments of the present invention, it is determined whether or not a disadvantageous change has occurred in a first communication mode, and when a disadvantageous change has occurred, a USB connection may be reset, thereby facilitating selection of the first communication m

Problems solved by technology

However, because this unique communication mode is not a function implemented in a device class/class driver of an individual terminal but a special communication mode prepared on the OS side, a case may arise where a USB interface (device class) originally included by the terminal may not be able to be used.
However, when switching to t

Example

[0073]Next, a second embodiment of the present invention will be described. In a smartphone, such as an Android terminal, communication, such as communication using a mirror link to which Virtual Network Computing (VNC) is applied in order to interact with an in-vehicle device, may be performed. However, because an operating system defined in the smartphone is basically used, the smartphone has not been optimized for control from the in-vehicle device. Thus, in order to perform a unique operation, a unique communication mode using a unique control command is effective.

[0074]Although a mirror link is usable in communication using WiFi, Bluetooth (registered trademark), or USB, selection of the bus supported by the mirror link is left to a vendor, and the case where communication using USB is offered is likely to increase in view of communication speed or stability. At this time, if a control command may be transmitted and received by using the same bus, a user's time and effort may b...

Abstract

An electronic device includes a connection unit that enables a USB connection to a smartphone, a normal communication mode in which communication is performed by using a device class prepared in advance in the smartphone, a request unit that makes a request for switching to a unique communication mode, a search unit that searches for a device class usable in the normal communication mode after the request for switching to the unique communication mode has been made, a determination unit that determines, on the basis of a search result, whether or not a disadvantageous change has occurred in the normal communication mode, and a reset unit that resets the USB connection when it is determined that a disadvantageous change has occurred.

Description

RELATED APPLICATION[0001]The present application claims priority to Japanese Patent Application Number 2012-234548, filed Oct. 24, 2012, the entirety of which is hereby incorporated by reference.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to an electronic device, an information terminal device, and an electronic system utilizing them, and more particularly to communication control between the information terminal device and the electronic device when the information terminal device is connected.[0004]2. Description of the Related Art[0005]In recent years, with the ever widening use of multi-function mobile phones typified by smartphones or the like, the frequency of use of smartphones in vehicles has been increasing. A smartphone has communication functions, for example, a third generation (3G) line, a Universal Serial Bus (USB) connection, and wireless data communications, such as WiFi and Bluetooth (registered trademark). The use of these functions...
