In the process, the central processor 51 also interacts with various external devices: via the IEBUS driver (CAN driver) 73 with sensors 30 and electronic systems (not shown) of the car, with the car speaker system 74, the car audio system 75 and an additional external audio source 76, with a power supply 77 and a power filter 78, which reduces on-board power interference falling into the LSI from the vehicle’s on-board network - battery 79, with external video devices (video camera 18, DVD devices and 20, etc.) through a digital serial bus ITU-R BT 656 YUV42 80. Also CPU 51 communicates with the element 81 and the backup power supply 82 located on the peripheral electronic board 4.

LSI has a dynamic memory capacity of 53 SDRAMs of the DDR or DDR2 type of at least 128 MB, a flash memory of 52 at least 512 MB, and a central processor speed of 51 at least 633 MHz. The external displays used must have a resolution of the standard range 800 × 600, 800 × 480, 640 × 480, 480 × 234, 400 × 234, 320 × 240, or may be any non-standard. Supported BIS interfaces: USB (Host, OTG); CAN 2.0B, IEBUS, UART 3 / 5B, SAE J1850, GVIF.

The on-board information system operates as follows.

The principle of operation of the LSI is based on the basis of multiplex and information-diagnostic systems, combining sensors, actuators and electronic units (not shown in Fig.). Electronic and software components of the LSI interact at the level of data exchange with each other, with the electrical components of the car and with external motorized regional and local communication, control, accounting and control systems (not shown in Fig.). Supported BIS interfaces: USB (Host, OTG); CAN 2.0B, IEBUS, UART 3 / 5V, SAE J1 850, GVIF.

The LSI electronic unit is connected to the vehicle electrical system. After the software is introduced into the electronic unit through the 27 USB HOST or 28 USB OTG jacks, the LSI operates in sixteen main modes, which make up the interactive main “MENU” and are output, when voltage is applied to the vehicle’s on-board network, in a color image on the screen of an external digital display 32 that connects to terminal 31 and is optional equipment. The items of the interactive main menu are displayed in the form of icons, pressing each of which opens the “MENU” within the mode. At the same time, four items of the main menu are displayed on the screen. The main menu is customizable, i.e. the user can adjust the order of output, name, color and font of the items and sub-items in the form they need, or create a completely new menu item. The initially installed main menu consists of 16 different items, which can be changed at the discretion of the manufacturer.

When the on-board information system is turned on, the central processor 51 starts to read the program block, previously written at the factory in the flash memory 52 into the dynamic memory 53 using the loader program, via the address and data buses. The width of the data bus 55 for dynamic memory 53 - 32 bits, for flash memory 52 - 16 bits. Then control is transferred to a read program that implements the algorithm of the on-board information system. In the dynamic memory 53 can optionally be loaded with various programs of the user's choice: navigation; media player; testing functions of the car and the LSI itself; programs for accessing the Internet; programs implementing security and monitoring functions; diary notebook and other LSI-compatible user programs that it can install on LSI independently.

Programs running in the central processor 51 gain access to various LSI modules by implementing the algorithms embedded in them.

Interaction with automobile sensors 30 and electronic systems is carried out by a peripheral processor or CAN controller 56 (depending on the car brand), using the IEBUS driver or CAN bus 73, respectively, which receive and send information necessary for coordinated LSI operation via IEBUS or CAN bus 59 with the vehicle’s electronic systems, for processing by the central processor 51, via the serial data bus UART 58 (for the peripheral processor) or SPI 57 (for the CAN controller).

The information processed by the central processor 51 can be stored in flash memory 52 and / or transmitted through video block 68, in which the digital signal is converted to an analog RGB signal using a digital-to-analog converter or converted to a digital GVIF signal and displayed on a display 32 via a video switch. Video block 68 allows using a video switch to connect the input of the display 32 to either a digital-to-analog converter of the video block or to additional signal sources 67. The display resolution can be selected from the standard range 800 × 600, 800 × 480, 640 × 480, 480 × 234, 400 × 234, 320 × 240 or be any non-standard. The display 32 may be equipped with a touch screen 34, which responds to pressing by changing the electrical resistance along the X, Y coordinates. The touch screen interface (not shown in FIG.) As part of the LSI video unit 68 suppresses interference from static electricity and cell phones in the signal from the touch screen 34 and transfers it to the central processor 51. Using mathematical functions, the program calculates from the electrical resistance of the touch glass at the X, Y coordinates the real coordinates of pressing the touch screen 34. On-board and The information system also outputs audio messages. The central processor 51 receives and sends the desired audio information through the audio block 65, through the audio codec 64, from the output of which the sound signal is fed to the LSI sound power amplifier and then to the car speaker system 74 through an external switch 60. The external switch 60 allows you to connect the car speaker system 74 or full-time audio system 75, or to LSI. The audio unit 65 through the audio codec 64 also has outputs of linear and balanced audio signals 62, 63, which are supplied through the audio switch (not shown in Fig.) To the car audio amplifier 61. The audio block 65 allows you to connect the input of the car audio amplifier 61 through the audio switch or to the audio codec 64, or to additional external audio sources 76.

Introduction and updating of software, data, connection of additional devices is carried out via USB Host 27 or USB OTG 28. Using the power supply unit 77, the BIS also provides power to external devices connected via USB via a standard USB cable. The BIS 76 power supply unit provides all the system components with the necessary power supply: + 1V, + 1.1V, + 1.2V, + 1.8V, + 2.5V, + 3.3V, + 5V. The power filter 78 reduces the interference of the on-board power supply falling into the LSI from the on-board network of the car - the battery 79.

When connecting external video devices (video cameras 18, DVD devices 20, etc.), the standard analog video signal transmitted by these devices is decoded by video block 68 using a video codec and converted into a digital stream, which is transmitted to the central processor 51 via an ITU-R BT digital serial bus 656 YUV42 80 for further processing.

To expand the amount of built-in flash memory 52 LSI uses external flash cards 11, 12 standards SD / SDIO / MMC / MMC 4.x, which interact with the central processor 51 through slots 9, 10 for connection.

To obtain the coordinates of the vehicle’s location, the LSI has a built-in GPS, or GLONASS, or GPS / GLONASS receiver 37, which is connected via an connector 35 on the LSI case 1 to an external GPS / GLONASS active antenna 36, which receives and amplifies signals from satellites. The received signals GPS / GLONASS, the receiver 37 transmits to the Central processor 51 via the serial bus UART 58.

A set of switches 25 is also located on the motherboard 3, which sets various LSI operation modes: display resolution, type of vehicle tires used, operation of interfaces.

If necessary, to expand the functionality, a peripheral electronic board 4 with an additional set of modules is connected to the BIS motherboard 3 by means of a plug 6 of the expansion connector and expansion slot 7 of the expansion connector: GSM modem 40, digital TV tuner 48, gyroscope 69, Bluetooth 46, WiFi / WiMAX 47, FM tuner 48.

The GSM modem 40 (GPRS / EDGE / 3G / 4G) allows the LSI to connect to the Internet, receive and transmit the necessary information, and make incoming and outgoing audio calls. The GSM modem 40 communicates with the central processor 51 through a plug 6 and a slot 7 of the expansion connector via the UART bus 58.

Access codes for the GSM network are located in the SIM card 14, which is installed in the holder of the SIM card 13. For the GSM modem 40 to work, an external GSM antenna 39 is required, which is connected to the LSI via the connector 38 on the housing 1.

The modules of the digital TV tuner 48 and the FM tuner 49 allow you to receive broadcasts in a digital and accordingly FM Stereo format and transmit the digital stream to the central processor 51 through the plug 6 of the expansion connector and slot 7 of the expansion connector. For the operation of digital TV and FM tuners 48, 49, external antennas 45, 44 are required, which are connected to the LSI through an opening on the housing 41.

The gyroscope 70 determines the angular movement of the car around its axis. The deviation is measured and the received data from the gyroscope 70 is fed to an analog-to-digital converter 71, from where the data stream converted into a digital signal is fed to the central processor 51 through the plug 6 of the expansion connector and socket 7 of the expansion connector.

Bluetooth 46 and WiFi / WiMAX 47 modules provide wireless connection with external devices (mobile phones, personal computers, access points, etc.). The received information is transmitted through the plug 6 of the expansion connector and socket 7 of the expansion connector to the central processor 51. For the operation of these modules, external antennas 42, 43 are required, which are connected to the LSI through an opening on the housing 41.

In the absence of the main power supply of the LSI, the progress of the internal real-time clock in the central processor 51 is provided by the backup power element 81.

The power supply 82 provides all the components of the peripheral electronic board 4 with the necessary power.

Depending on the modification of the LSI, the peripheral electronic board 4, as well as all or part of the described modules of the peripheral electronic board 4 may not be installed, which does not affect the overall performance of the system, but only reduces or changes the number of functions performed by it.

LSI control is performed using various input devices 71: a computer mouse, keyboard, joystick, trackball, etc., connected via USB connectors 27, 28, a touch screen 34 connected to LSI connector 33, information received via CAN or IEBUS 59 buses car over the internet.

The system can be in three main states.

1. Lack of supply voltage

All modules of the system, except for the real-time clock, are de-energized, and the clock is powered by backup element 81.

2. Standby

The power supply unit of the system 76 provides power only to the peripheral microcontroller and CAN controller 59, the central processor 51 and dynamic memory 53, which are also in the minimum power consumption mode, which saves the energy of the vehicle’s battery. If the necessary input conditions are present, the central processor 51 supplies a turn-on signal to the power supply unit 76. The power supply unit 76 and the entire system go into operation mode.

3. Operating mode

All system modules are powered. The central processor 51 processes the incoming information from the interfaces according to the algorithm specified in the software.

To the multi-pin electrical connector 26 (male part), the receptacle of the multi-pin electrical connector 26 with a locking device (not shown in FIG.) Is connected to a harness (not shown in FIG.) That connects the car computer to the vehicle’s on-board network - battery 79.
