Hereinafter, a possible implementation of the in-vehicle information communication service system of the present application will be described with reference to the drawings.

1 shows the overall architecture of an in-vehicle information communication service system in accordance with one possible embodiment of the present application. As shown in FIG. 1, the in-vehicle information communication service system 100 includes an in-vehicle infotainment host (IVI) 110 and an in-vehicle communication module (TBOX) 120 communicatively coupled to the in-vehicle infotainment host 110. The structure and function of the two modules of the in-vehicle infotainment host 110 and the in-vehicle communication module 120 according to the present application are as follows.

The in-vehicle infotainment host 110 includes a human-machine interaction interface 112, a first processor (IVI CPU) 114 communicably coupled to the human-machine interface 112, and a first microcontroller communicatively coupled to the first processor 114. (IVI MPU) 116. The human-computer interaction interface 112 is, for example, an LCD or a touch screen for displaying various function information at a graphical user interface thereon and receiving operational instructions input by the user. As shown in FIG. 2, the first processor 114 is integrated with an operating system such as a Linux operating system. The first microcontroller 116 acquires vehicle body data via a body bus (eg, a CAN bus), such as vehicle condition data such as vehicle speed, reverse, and the like. The in-vehicle infotainment host 110 primarily performs multimedia functions and vehicle bus communication tasks. Moreover, the in-vehicle infotainment host 110 also implements a human-computer interaction function through the human-machine interaction interface 112. As shown in FIG. 4, the functions of the in-vehicle infotainment host 110 include basic functions, multimedia functions, communication functions such as Bluetooth phones, mobile phone interconnection functions, and vehicle setting functions. Here, the basic functions include various diagnostic and monitoring functions via the CAN bus. Multimedia features include audio and video capabilities. Vehicle setting functions include the ability to issue vehicle warning tones and display reversing images.

In this way, the in-vehicle infotainment host 110 only performs local functions and interface display functions that do not require cloud network data. Thus, the processor (IVI CPU) and the microcontroller (IVI MPU) of the in-vehicle infotainment host 110 have higher cost performance and lighter weight characteristics, thereby reducing the cost and structural complexity of the in-vehicle infotainment host.

With continued reference to FIG. 1, the in-vehicle communication module 120 includes a second processor (TBOX CPU) 123 and a satellite navigation module 121, a communication module 122,

memories

Moreover, the in-vehicle communication module 120 further includes an antenna interface (not shown), a power interface (not shown), and a bus interface (not shown) disposed thereon. The in-vehicle communication module 120 acquires cloud data via a network through an antenna interface. The in-vehicle communication module 120 obtains a power supply through a power interface, for example, a 12V power supply. The in-vehicle communication module 120 acquires vehicle body data of the vehicle through a bus interface. The second processor 123 is a high performance CPU, such as a Cortex-7 architecture, 4 cores. As shown in FIG. 2, an operating system, such as an Android operating system, is integrated on the second processor 123.

Moreover, the in-vehicle communication module also receives a return control command to perform a return control operation. Thereby, the number of variants of various corresponding in-vehicle communication modules required in the case of platform migration and expansion is reduced.

The communication interface between the two modules of the in-vehicle infotainment host 110 and the in-vehicle communication module 120 is a physical interface. For example, the communication interface is a USB interface, and data communication between the two modules is based on a USB-based protocol. Of course, the communication interface may also be other forms of interfaces depending on the specific application scenario. The audio video signal between the two modules can be transmitted based on the H.264 codec form, although other suitable codec forms can be used.

Map data is stored in the EMMC memory 125. The second processor 123 matches the received destination information with the map data stored in the EMMC memory 125. After the matching is successful, the second processor 123 generates man-machine interface information for navigation to be displayed, and the man-machine interface information is transmitted to the in-vehicle information via a communication interface (for example, a USB interface), for example, in the form of H.264 encoding.
