The system design has at least 16 KB of RAM (RAM) (not shown in FIG.), At least 64 MB of permanently flashing device memory (ROM) (at FIG. Not less), and the system’s CPU speed is at least 64 million operations per second. The digital display 4 of the color image used in the design of the system has a diagonal size of 13.9 cm with a resolution of 320 × 240 pixels and a contrast ratio of 400: 1.

Car airborne information system operates as follows.

The principle of the system is based on the basis of multiplex and information-diagnostic systems, combining sensors, actuators and electronic units (not shown in Fig.). Intelligent components of the system interact at a data exchange level with each other, with electrical equipment nodes and with external motorized regional and local communication, control, metering and control systems (not shown in Fig.).

Supported system interfaces: K-line in accordance with ISO 9141 and ISO 14230-1; USB (Host, Slave) USB-OTG; 1-Ware; CAN 2.0B.

The system software, introduced into the electronic unit through slot 8 “USB”, provides for the operation of the system connected to the vehicle’s on-board network in eight main modes that make up the main “MENU” and are displayed in color on the digital display 4 in the form of icons and key designations, pressing each of which reveals "MENU" within the mode. The software is implemented in a training mode for the convenience of the user.

Basic operating modes:

1. The route.

2. Service.

3. Navigation.

4. TV.

5. Phone.

6. The Internet.

7. Settings.

8. Games.

To enter the main diagnostic mode “Service”, which contains all the information about the car, the management of its devices, and so on, it is envisaged to enter a conditional password for using information only by the car owner.

For security reasons, the modes "TV", "Internet", "games" when the car is moving are automatically turned off.

The key marking of the keyboard 10 is translucent. Translucence is provided by LEDs, the brightness of the indication automatically changes from the signal of the photosensor 12 depending on the illumination of the interior, which allows you to read the markings both in direct sunlight and in the dark. Adjusting the color of the light emitted by the LEDs allows you to adapt the color of the marking to the design of the dashboard display of any car. The optical fibers 11 perform the functions of an additional indication emitted by the LEDs with green, yellow and red colors and their combinations defined by the hardware and software. The photodetector 13 provides the ability to control all functions of the system from a remote control (not shown in Fig.) With a keyboard identified by marking with the keyboard 10 of the electronic unit. Contact slots 6 "audio" and 7 "video" are used to connect audio and video systems, contact slot 8 "USB" is used to connect peripheral devices that provide programming, reprogramming (laptop, personal computer, flash block with maps for navigation, printer and etc.). Through the inverter board 14, the screen of the digital display 4 is automatically turned on and its operation is maintained during the entire period of power supply from the on-board network to the system. The built-in speaker 15 performs the sound signals provided by the program. With a multi-pin electrical connector 17, a wiring harness is connected with wires (not shown in FIG.) For connection to the vehicle electrical system. A bundle of wires 20 with plugs allows you to connect a miniature video camera 21 rear view, input and output amplifier, speakers of the car (not shown in Fig.). The rear view camera 21 is automatically activated when the reverse gear of the car is turned on and it is moved backward, while a panorama view of the rear view appears on the screen of the digital display 4, the car's backward movement is also accompanied by a loud voice. Communication with the amplifier and sound speakers of the car provides the sound of music and television programs, as well as other functions provided by the program, the sound power is controlled by the keys of the keyboard 10. The main board 16 is installed horizontally in the guide grooves of the housing 2, the tuner is also placed on it (in Fig. shown) with an outlet 18 for connecting a cable (not shown) of an external antenna 19, a contact pin 17, connectors for a bundle of wires 20, an inductor and capacitors and self-contained power source for watches (Fig. not shown). The active antenna 19, mounted on the roof of the car and connected by a cable to the socket 18, provides reception of television programs.
