Description

The invention relates to computing and information-measuring equipment and can be used in vehicle control systems.

Known Information-command system of the aircraft [1], containing three widescreen liquid crystal indicators, which display all the information about the operation of the aircraft systems, a display generation unit, electrically connected to a control signal generation module, a search and recommendation module and a data comparison module , which is connected with the computer calculator of airborne navigation systems and with the airborne signal system, the on-board test control system associated with the control signal generation module als and with a module for generating logical commands, engine control levers, pedals, side control knobs with four-position push buttons with neutral buttons installed on the workplaces of the commander and co-pilot, and a voice informant, emergency command unit, including a manual control module with feedback pushbuttons, which provide control signals to the actuators of the aircraft systems, and the actuator switching module.

Closest to the invention in technical essence is the well-known car control system [2], comprising: a digital computer, a steering column switch, an indicator on the windshield (Head-Up Display) and a monitor.

These devices have several disadvantages.

The control system [1] does not display information on the windshield, which means that it forces alternately to switch attention to the inside and inside spaces. Therefore, it can not be used to improve road safety and ergonomics of the driver’s workplace.

The control system [2] does not provide increased road safety, since the use of steering column switches as the controls of various vehicle systems forces the driver to control the vehicle with one hand for some time. Management of the entire complex of user vehicle systems using this system also leads to an increase in the number of shift paddles or the number of manipulations with them.

The task solved by the interactive control system is the ability to control all user systems of the car (climate control, multimedia systems, navigation, communication) without taking their hands off the steering wheel, but looking from the traffic situation, increasing the information content and the convenience of perceiving information. What provides increased road safety and ergonomic improvement of the driver’s workplace.

The essence of the invention lies in the fact that the control system containing a digital computer, LCD monitor, projector, controls, additionally contains a digital computer, light sensor, as an indicator on the windshield (ILS), a laser projector is used in conjunction with a film coating on the windshield, and in As controls, buttons on the steering wheel are used, made in conjunction with capacitive sensors.

The invention is illustrated by the diagram in figure 1, which indicates:

1 - digital computer;

2 - BTsVM;

3 - Capacitive sensors;

4 - The block of control buttons on the steering wheel;

5 - Light sensor;

6 - Controller of analog sensors;

7 - Exchange controller;

8 - Laser projector;

9 - LCD monitor;

10 - Controllers of user systems;

11 - Custom vehicle systems (climate control system, multimedia system, navigation system);

12 - Service vehicle onboard systems;

13 - Sensor equipment;

14 - Film coating of a windshield;

15 - Windshield of a vehicle.

In the proposed vehicle control system:

The control buttons 4, the capacitive sensors 3 and the light sensor 5 are connected to the digital computer 1 through the analog sensor controller 6, the digital computer 1 is connected to the laser projector 8 and the monitor 9, and through the exchange controller 7 to the digital computer 2, also through the controllers of user systems 10, the digital computer 1 is connected with a climate control system, navigation system, multimedia system, a film coating 14 is glued to the inner surface of the windshield in order to eliminate image reflections and provides light transmission within the limits specified by GOST.

BTsVM 2 is the main control device for that part of the on-board systems that operate without driver intervention - on-board on-board systems 12. The on-board computer 2 within the framework of this system is designed to provide information from the sensor equipment 13 and on-board on-board systems 12 to TsVM 1.

The exchange controller 7 is designed to interface with a digital computer 2 and digital computer 1.

Digital computer 1 is the main control device of the user on-board systems 11, which can be directly used by the driver.

The laser projector 8 serves as an information display device, the advantages of which are: high image contrast, no need for focusing, the ability to display important information for the driver in a convenient place for him, an increased service life in relation to analogues. These advantages of a laser projector allow you to use all the functions of specialized image processing programs in order to increase the information content, convenience and speed of reading the displayed information.

Windshield film coating 14:

- a film that allows you to project an image on optically transparent planes (Polyscreen Films);

- a polarized film, the plane of polarization of which differs from the plane of polarization of the laser beam by an angle close to 90 °;

- tint film.

At the same time, the light transmission of the film itself should be within the limits established by GOST 5727-88 “Safety glass for ground transportation”, which allows it to be used on the windshield of a car.

The buttons on the steering wheel 4 are the controls of the user systems of the vehicle 11 during movement.

Capacitive sensors 3 are pieces of electrical conductor of small cross-section or contact pads of small area, mounted on the inner surface of the buttons. They are designed to generate a signal about touching the control button until the button itself works.

The light sensor 5 is designed to measure the level of light outside the car.

The controller of analog sensors 6 is intended for:

- pairing buttons on the steering wheel 4 and computer 1;

- ensuring the sensitivity adjustment of capacitive sensors 3, eliminating false alarms when the buttons are inadvertently touched and issuing information to digital computer 1 about which sensor worked;

- pairing the light sensor 5 with a digital computer 2, which according to its signals regulates the brightness of the displayed information both on the LCD monitor 9 and on the windshield through the projector 8.

The essence of the controller analog sensors 6 is illustrated in the diagram in figure 2, which indicates:

1 - microprocessor;

2 - capacitive sensors;

3 - a block of buttons on the steering wheel;

4 - light sensor.

LCD monitor 9 is an additional information display device that can be used both with and without projector 8.

The controllers of user systems 10 are designed to interface user systems 11 and a digital computer 1.

User systems 11, controlled in the process of movement by buttons on the steering wheel 4, also have independent controls, ensuring the reliability of the control system as a whole and the convenience of control during parking. At the same time, information about changing the parameters also through the controllers of user systems 10 enters the digital computer 1 and is displayed on the LCD monitor 9 and the windshield (film coating 14) with the projector 8 turned on.

Interactive vehicle control system (control system) operates as follows.

After turning on the control and loading system, CVM 1 has complete information about the state of the vehicle as a whole from user systems 11 controlled by it, as well as on-board on-board systems 12 and sensor equipment 13, through the digital computer 2. From then on, the digital computer 1 provides output to the LCD monitor 9 and windshield (film coating 14) through the projector 8 the following types of information:

a) Constantly displayed information (speed, indication of the included direction indicators, engine speed, gearbox gear number, navigation information, symbolic information about the operating modes of various systems (dipped or main beam, parking brake, not fastened seat belt, Sport mode enabled) " etc.).

b) Periodically displayed information (indication of the parameters of user systems that are changed with the help of the controls, in the process of changing them);

c) Alarms based on signals from sensor equipment and on-board systems (pressure drop in tires, decrease in brake fluid level, increase in coolant temperature, etc.). At the same time, the digital computer gives the driver brief recommendations on his further actions in the current situation through the vehicle audio system according to the algorithms laid down in it.

The driver in the process of driving the vehicle also controls the user systems 11 using the buttons on the steering wheel 4. In this case, due to the large number of modern user systems of vehicles, it becomes necessary to increase the functions of each control button on the steering wheel (long press or short, simultaneous press of 2 buttons) , therefore, to facilitate the difficult-combined operator activity of the driver, capacitive sensors 3 are used. When you touch the control button 4 with a given force, on the forehead In the glass (film coating 14) and on the monitor 9, the current value of the parameter that is controlled by this button in the selected mode of its use is displayed. And only after the button itself is triggered, the selected parameter changes, which is also displayed on the windshield and monitor 9.

The driver can control all user systems 11 using the direct controls on the dashboard, and the change in parameters is also displayed on the monitor 9 and on the windshield when the projector 8 is on.

Digital computer 1 can be used as a trip computer and provide Internet access via wireless communication channels (GPRS, 3G, Wi-Fi, WiMAX, etc.)

Thus, the proposed interactive system can significantly improve road safety and simplify the work of the vehicle driver in managing all user systems.

The presented schemes and the description of the proposed interactive system make it possible, using the existing element base, to manufacture it industrially and use it in the control systems of vehicles: cars, trucks, buses, etc., which characterizes the invention as industrially applicable.
