Smart AVN system interactively operating with smart phone

The present invention relates to a smart audio visual navigation (AVN) system that interoperates with a smart phone, and more specifically, a hardware and a smart phone that complements the function of the smart phone to the car audio having only the existing simple audio function and By adding the ability to communicate, it integrates the audio, video and navigation functions of the smartphone with the car audio system and makes use of the functions of the other device, enabling the use of simple audio devices as a high-performance car AVN system. The present invention relates to a smart AVN system that interoperates with a smartphone capable of achieving a high-performance AVEN system while lowering the manufacturing cost of the system.

As is well known to those skilled in the art, the AVN system, which is an automobile multimedia device, includes a sound device, a high performance navigation device, an expensive display device, and the like, which are somewhat different depending on the vehicle type. The car AVN system including the sound device, the navigation device, and the display device provides various functions for the user (driver) to enjoy the multimedia, and also provides a high performance navigation function in conjunction with the GPS and the Gyro. . However, such a car AVN system has a relatively expensive manufacturing unit and display device for each function has a problem that the manufacturing unit price increases accordingly, and also because the car AVN system is difficult to remove and upgrade, it is difficult to upgrade and add features There was a problem that its usability is poor. In other words, the existing car AVN system is an independent product that implements only AVN (Audio Visual Navigation) function including navigation. Therefore, if the hardware performance is not improved, it is difficult to implement the improved navigation and There was a problem that the lifespan is limited. In addition, since the existing vehicle AVN system is fixedly installed and used in the vehicle, it is necessary to remove and work on the device in order to update the product or add new contents, but the work is very inconvenient.

Meanwhile, smart phones, which can be used for various applications (applications) such as the Internet, music, video, and navigation, have been widely used in mobile phones, providing many convenient functions to users. One of the biggest advantages of smart phones is that users can freely download and install the applications they want, and they can communicate on the go, send and receive e-mails, send faxes, and manage personal information. Therefore, the most distinctive feature of the smartphone is that it is possible to install, add or delete hundreds of various applications (applications) as users want, unlike conventional mobile phones that are released as finished products and use only given functions. In addition, as the spread of smart phones expands, the number of users who utilize various functions of smart phones in cars, which are a major means of transportation, is increasing.

By the way, in order to listen to the audio including the music in the smart phone through the earphone or built-in speaker to use such a smart phone in a limited way through the complicated connection device can be utilized in a limited way, but the operation is inconvenient and fixed the smartphone A device is needed to do this. In addition, although the smartphone allows many applications to be used, when using applications such as navigation, the smartphone itself is not a dedicated device for navigation, so the performance of the built-in GPS receiver is poor, but navigation is not available in areas where GPS is not received. There was a problem that can only use the reduced navigation function than that provided by the navigation-only device, such as not working.

In addition, the navigation application implemented in a smart phone employs a method of directly touching a screen for most operations, but due to the nature of the smart phone, the operation of the navigation application is very difficult in a vehicle.
