Description

The invention relates to simulator visualization systems and can be used to visualize vehicle simulators, including passenger car simulators.

Known modular simulator with a display / 1 / containing three video monitors that display three different windows (sectors of the simulated space). Each monitor is enclosed in a separate case and the cases are mounted on the simulator close to each other, forming a panorama.

A disadvantage of the known device is that it does not provide visualization of the inner and left outside rear view mirrors, without which the operation of a car is not allowed. In addition, in the known device, monitors are located close to the user, due to the limited size of the screens of the monitors. Examining the image on the monitor screen at close range greatly tires the eyesight.

There is also known a method and device for teaching driving vehicles / 2, 3 /, when on the screen installed opposite the student’s control panel, sequences of images are visually reproduced, which vary depending on certain commands received from the control panel. The image of the front section and the images for the inner and two exterior side rear-view mirrors in the form of windows on the same screen are simultaneously presented on the screen. The user views the image for the inner mirror directly in the corresponding window of the screen through the transparent dummy of the inner mirror, and the images in the exterior mirrors also represent the images in the corresponding windows of the screen, viewed through the side and auxiliary mirrors proper, integrated into the control panel.

A disadvantage of the known device is the lack of visualization of the side sections of the surrounding space, which narrows the functionality of the device, not allowing the learner to reproduce the interference with the movement to the left and right at a small distance from it.

A known simulator for training truck drivers / 4 /, in which the image forming system comprises several video projectors controlled by electronic data processing devices, the video projectors divided into two groups reproducing the image on projection screens installed outside the cab. Video projectors of the first group and projection screens are located in front of the cabin and on the side of it and the images created on the screens are visible through the windshield and side windows of the cabin.

Video projectors of the second group and their projection screens are located at the rear of the cab so that the images they create are visible through the external rear-view mirrors. A disadvantage of the known simulator is the high cost, a significant part of which is the cost of seven video projectors.

The aim of the present invention is to reduce the cost of the visualization system by minimizing the number of projectors required to visualize viewing areas through the windshield, left and right side windows, and the vehicle’s internal outside rearview mirror.

This goal is achieved by the fact that in the well-known simulator visualization system containing a multimedia projector controlled by a computer image generator, and projection screens, three of which are installed vertically at the front of the simulator cabin, forming a panorama, and the fourth - vertically at the rear wall of the cabin, eleven flat mirrors, eight of which are grouped in pairs and form four periscopic systems, and three are introduced into the parts of the initial light flux of the projector, reflect h luminous flux and change the direction of light propagation in them relative to the original one so that after reflection from the mirrors of the corresponding periscope system, each part of the light flux reaches the corresponding screen, including the one that passed unhindered between the three aforementioned mirrors, and the plane of symmetry of the cab and system "projector-mirror-screens" form a certain angle, so the fourth screen protrudes from the side of the cab.

The essence of the claimed technical solution is illustrated by the drawing, including figures 1, 2, 3, 4, 5 and 6. Figure 1 shows the location relative to the cabin 1 of the simulator of the projector 2, mirrors 3, 4 and 5, dividing the original light flux of the projector into four different directions Ia, Ib, II and III, and projection screens 6, 7, 8 and 9.

Figure 2 presents the geometric characteristics of the luminous flux of the projector used in the layout of the system.

Figure 3 shows a section aa from figure 1 and presents the mirrors 10 and 11 of the periscope system, bringing the luminous flux Ia to the side screen 8.

In Fig. 4, section BB is shown in Fig. 1, and the mirrors 12, 13 of the periscope system that bring the light flux III to the screen 7, and the mirrors 14, 15 of the periscope system that bring the light flux II to the screen 9.

Figure 5 shows the division of the projector format into windows provided by a computer image generator.

Figure 6 presents a simplified diagram of the overview provided by the driver of the Moskvich 2141S passenger car with the left side, wind, right side and rear windows of the cab, as well as the inner and left exterior rear-view mirrors.

An example of the proposed system is the visualization system of the Moskvich 2141S passenger car simulator.

A multimedia projector 2 is mounted horizontally above the hood of the simulator cabin 1 in an inverted position, as shown in FIG. 1, FIG. 3 and FIG. 4. The geometric characteristics of the luminous flux of the projector used in the layout of the system are presented in figure 2.

In the luminous flux of the projector, mirrors 3 and 4 are introduced vertically from above, arranged as shown in FIG. 1, FIG. 2 and FIG. 4. Separated by mirror 3, part Ia of the total light flux of the projector, after reflection from the mirrors 10 and 11 of the periscope system, is projected onto the right side screen 8 of the system. Separated by the mirror 4, the part 16 of the light flux is projected similarly onto the screen 6 of the system.

From below, a mirror 5 is introduced into the light flux of the projector, located as shown in Fig. 1 and Fig. 4. Separated by mirror 5, part III of the total luminous flux of the projector, after reflection from the mirrors 12 and 13 of the periscope system, is projected onto the central screen 7 of the system.

Passing between the mirrors 3, 4 and 5, part II of the total luminous flux of the projector after reflection from the mirrors 14 and 15 of the periscope system is projected onto the rear screen 9 of the system.

Since the plane of symmetry of the cockpit 1 of the simulator and the system "projector-mirror-screens" form an angle of about 7 degrees, part of the screen 9 protrudes overboard of the cab 1.

The simplified review diagram presented in FIG. 6 is constructed for a calculated point of view located at the intersection of the cervical spine and a horizontal plane drawn through the centers of the eyeballs of the driver. Dotted lines on the overview diagram show fields visualized using screens 6, 7, 8, and 9 of the same height.

The system works as follows. A computer image generator that controls the operation of a multimedia projector in accordance with the simulated traffic situation and the student’s actions generates video signals of five different images of the external visual environment, which are five windows in a single projector format, as shown in FIG. 5.

The initial light flux of the projector 2 is divided by mirrors 3, 4, and 5 into four differently directed light fluxes Ia, Ib, II, and III, each of which is brought by the following mirrors of the corresponding periscope system to the corresponding screen. The total angular horizontal view of the images on screens 6, 7 and 8 from the calculated point of view is approximately 140 degrees. The image of the two windows of the projector format on the screen 9 allows you to visualize both the inner and outer left rear view mirrors of the cab, without which the operation of the car is not allowed.

Thus, the claimed technical solution, providing visualization of the left side, wind, right side windows and two rear-view mirrors of the simulator cabin from one single projector, has, according to the applicant, novelty. An analysis of the well-known technical solutions in the field of visualization devices for vehicle simulators allows us to conclude that there are no signs similar to the essential distinguishing features in the claimed system, and, according to the applicant, allows the claimed solution to be recognized as meeting the criterion of "inventive step".
