Description

  The present invention relates to an in-vehicle system and a mobile terminal device in which a mobile terminal device and an in-vehicle device are connected by wireless communication.

  With the spread of car navigation systems using GPS (Global Positioning System), in-vehicle devices having a navigation function are often mounted on vehicles. In addition, in order to respond to user needs for multifunctional in-vehicle devices, multifunctional in-vehicle devices have become prominent.

  For example, in-vehicle devices can be used with simple operations regardless of the skill of the driver (user) such as TV reception function, CD (Compact Disc) playback function, DVD (Digital Versatile Disk) playback function in addition to the navigation function. Many functions are included.

  While many functions with such a high usage tendency are included, many new navigations in which functions are further added to the navigation functions have been proposed. For example, a function for displaying on the display that the vehicle is approaching a dangerous area (such as an accident-prone area or an area with poor visibility) and a function for displaying advertisement information in addition to conventional map information have been proposed. In addition, the increase in the number of functions of the in-vehicle device causes an increase in the price of the in-vehicle device, which is not preferable for the user.

  On the other hand, portable terminal devices such as mobile phones have been popularized at low prices but with navigation functions and music playback functions. In addition, since mobile terminal devices equipped with a short-range wireless communication function such as Bluetooth (registered trademark) have also become widespread, efforts have been made to link the mobile terminal device and the in-vehicle device with such a short-range wireless communication function.

  However, the above-described conventional technology has a problem that it is not possible to safely provide appropriate information for the driver at an appropriate timing without causing any trouble in driving.

  Specifically, the navigation that displays that the vehicle is approaching the danger area sends the location information of the vehicle to the center and receives information about whether or not the vehicle is driving near the dangerous state. And it is shown on the display. In this case, the navigation only displays the information received from the center as it is on the display, so it will be useful information for the driver on the unfamiliar road for the first time, but it will be annoying for the driver on the accustomed road for frequent driving. It becomes.

  Similarly, navigation for displaying advertisement information is also received from the center or read from map information such as a DVD according to the driving situation. Therefore, although it is useful information for the driver on the road that travels for the first time, it is only troublesome information for the driver on the road that travels frequently, such as around the home or around the destination that is frequently visited in the past. In addition, in the navigation for displaying advertisement information, information that can be advertised is limited to large corporations, major restaurants, public authorities, etc., and it is difficult to display detailed information around the destination.

  As another technique, there is a mobile terminal device that communicates with a center and periodically updates information. However, when information is updated during driving, the driver needs to check the information by viewing the display of the mobile phone device. In other words, when the information is updated, the mobile phone device notifies the driver that the information has been updated by vibration or ringtone. However, it is very dangerous for the driver to operate the mobile phone device unless it is stopped. Therefore, there are many cases where the information cannot be confirmed immediately after being updated. Therefore, even if the necessary information is provided, it is highly likely that the driver cannot view the information at the provided timing, and the appropriate information is safely provided at the appropriate timing. hard.

  Accordingly, the present invention has been made to solve the above-described problems of the prior art, and it is possible to safely provide appropriate information for the driver at an appropriate timing without causing any trouble in driving. An object is to provide an in-vehicle system and a portable terminal device.

In order to solve the above-described problems and achieve the object, the present invention provides an in-vehicle system in which a mobile terminal device and an in-vehicle device are connected by wireless communication, and the mobile terminal device that the driver brings into the vehicle includes: Based on the position information where the vehicle on which the in-vehicle system is mounted is located, service information receiving means for receiving service information from the center, and received by the service information receiving means based on the vehicle information received from the in-vehicle device.
