Car computer works as follows

The principle of operation of an automobile computer is based on the basis of multiplex and information-diagnostic systems combining sensors, actuators, and electronic units (in Fig.

shown). Intelligent components of an automobile computer interact at a data exchange level with each other, with vehicle electrical equipment nodes, and with external motorized regional and local communication, control, metering, and control systems (not shown in FIG.). Supported car computer interfaces: K-line in accordance with ISO 9141 and ISO 14230-1; USB (Host, OTG); CAN 2.0 V.

The software of the car computer, entered into the electronic unit through the sockets 5, 6 USB HOST or 7 USB OTG, provides for the operation of the car computer connected to the on-board network of the car in the seven main modes that make up the 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 15, connected to the contact socket 14 and which is additional equipment in the form of pictograms and marking the keys of the remote control 34 controls, each press of which opens “MENU” within the mode. For user convenience, the software is in the form of training.

Basic operating modes:

1. The route;

2. Navigation;

3. Multimedia;

4. Service;

5. Settings;

6. Organizer;

7. Help;

To enter the main mode of operation "Service", containing all the information about the car, the management of its devices, and so on, it is envisaged to enter a conditional password for using the information only by the car owner.

A control module 9 is connected to the contact socket 8, consisting of a power-on indicator 10, an infrared receiver 11 for a remote control (RC) 34, a microphone 12, a speaker 13.

The microphone 12 and the speaker 13 provides hands-free telephone communication with subscribers and control functions of the unit with the driver’s voice messages, which creates additional safety conditions when driving a car. The infrared receiver 11 provides the ability to control all the functions of the car computer from the remote control 34. The built-in speaker 13 will emit sound signals provided by the operating modes, for example, when exceeding the set speed limit, for a given time to turn on the alarm, etc.

USB connectors 5, 6, 7 are used to connect peripheral devices that provide programming, reprogramming, introducing hardware and software, implementing navigation functions and other functions (laptop, GPS-receiver, personal computer, flash keychain with navigation cards, printer and etc.).

When the on-board information system is turned on, the central processor 17 starts to read the program block, previously recorded at the factory, from the flash memory 18 into the dynamic memory 19. After that, control is transferred to the read program, which implements the algorithm of the on-board information system. The interaction of the central processor 17, flash memory 18, dynamic memory 19 occurs using the address bus 20 and data 21. The peripheral processor 22 collects information from the sensors of the vehicle 25 and transmits it to the central processor 17 for processing through the serial data bus 23. The processed information can be stored in the flash memory 18 and / or is displayed on the display 15 through the graphics processor 26. The on-board information system displays and

sound messages. The central processor 17 sends the audio information to the audio codec 27, from the output of which the sound is amplified by the sound power amplifier 29 and supplied to the speakers 28 through the audio switch 30. Software, data, and the connection of additional devices are updated via USB Host 5, 6 or USB OTG 7. Management the device is carried out using a control module 9 connected to a peripheral processor 22. 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 31.

2. Standby

The power supply unit of the system 24 provides power to only the peripheral processor 22, which monitors the state of the input signals in accordance with a given program. Energy consumption is minimal, which saves the energy of the car battery. If the necessary input conditions are present, the peripheral processor 22 provides an enable signal to the power supply 24. The power supply 24 and the entire system go into operation.

3. Operating mode

All system modules are powered. The central processor 17 processes the incoming information from the peripheral processor 22 according to the algorithm specified in the software.

To the multi-pin electrical connector 16 (male part), the receptacle of the multi-pin electrical connector with a locking device (not shown in FIG.) Is connected to a harness (not shown in FIG.) Connecting the car computer to the vehicle electrical system. The fastening elements 33 of the electronic unit of the car computer are used to install and fix the electronic unit in the car panel.
