Description

. TRAINING SIMULATOR FOR VEHICLE DRIVING A useful model refers to technical means of teaching driving a vehicle and can be used to teach driving a car, as well as to improve and quickly assess the degree of development of professionally significant motor skills. A known simulator for learning to drive a car, which is a workable car equipped with means for determining the position of the controls, which are connected to a computer-processed information processing device that is located outside the aforementioned car, includes a motion simulation tool, a loudspeaker for reproducing a signal simulating noise arising from movement, and a display for displaying the visual environment (DE19928490, publ. 28.12.2000). The device is bulky and difficult to operate. At the same time, it is not possible to take into account changes in the position of the learner’s head and the direction of his gaze, as occurs in the real process of driving. A device for assisting in teaching a vehicle driving is also known, which includes means for determining the position of vehicle controls installed in the driver’s cabin, video cameras for determining the position of the learner’s head and gaze, an acoustic system and an information display device connected to a computer information processing device including a tool for selecting operating modes as well as shapers of audio and video signals (FR2618244, publ. 01.20.1989). However, since this device can only be used in a moving vehicle, its scope is limited. So, for example, for its operation it is necessary to have a special platform, or to carry out training on the road in traffic conditions. In addition, this unit is not suitable for teaching basic driving skills. IPC 7 G 09 V 9/04

means for determining the position of the vehicle’s controls, head position and learner’s gaze, an acoustic system and an information display device connected to a computer information processing device including a simulator operating mode selection tool associated with the vehicle’s motion simulation tool and an audio signal generator and a shaper of video signals, including signals simulating a visual environment when a vehicle is moving, pre designed to transmit these signals, respectively, to the speaker system and means of displaying information (DE No. 10033442, publ. 31.01.2002). Mandatory use in this simulator for determining the position of the head and the gaze of the learner a special helmet equipped with display means and an acoustic system leads to the fact that the conditions in which the learner is located are very far from real driving conditions, while it is impossible to use other types of information display devices , for example, a monitor. In addition, the inconvenience in learning is created by the absence of a dedicated test mode, through which you can set training parameters that correspond to the experience and physical data of the student.

The technical result of this utility model is to eliminate the disadvantages of the above simulators, so that:

1. Improve the quality of training for car drivers, through the formation of their initial skills of optimal actions with the management bodies in regular and critical situations.

2. To carry out primary and advanced training of drivers in driving schools, sports-technical and secondary schools.

3. Improve and test the degree of development of professionally significant car driving skills for experienced drivers.

4. Improve the quality of training through the use of computer simulation of visually information and noise accompanying the movement of the car.

5. Reduce the cost of training by reducing the resource consumption of vehicles designed for training and combustible lubricants.

6. To increase the flexibility of pedagogical technology in the implementation of driver training, which, in turn, will lead to an increase in the quality and efficiency of driver training and a reduction in traffic accidents in this regard.

The technical result is achieved by the fact that in a simulator designed to teach driving a vehicle and containing a driver’s workplace, means for determining the position of the vehicle’s controls, head position and / or learner’s gaze, an acoustic system and an information display device connected to a computer processing device information, including a tool for selecting simulator operating modes associated with a vehicle motion simulation tool, and As well as a shaper of audio signals and a shaper of video signals, including signals that simulate the visual situation when the vehicle is moving, intended to be reproduced by the acoustic system and the means of visual display of information, the computer information processing device includes testing means associated with means for selecting the operating mode of the simulator and the shaper video signals, and a means of adjusting the signals simulating the visual environment when moving conveyor at least one video camera was used as a means of determining the position of the head and / or the direction of the learner’s gaze associated with the video driver, as a means of determining the position of the head and / or the direction of the learner’s look, and the audio signal generator is associated with the vehicle motion simulation tool means for generating noise simulation signals while driving a vehicle.

In FIG. 1 shows a block diagram of a simulator. the provisions of the bodies 3 of the vehicle. The position of the student’s head and / or eyes (to determine the direction of gaze) is controlled by a video camera 4 located at approximately the level of the student’s head, connected to the computer information processing device 5. The latter is associated with the acoustic system 6 and the means of displaying information 7. The computer device 5 includes a means 5.1 for selecting the operating modes of the simulator associated with means 5.2 for simulating the movement of the vehicle and means 5.3 for testing, as well as a shaper 5.4 of audio signals simulating noise arising from movement vehicle, and the shaper 5.5 video signals, including signals simulating the visual environment when the vehicle is moving. The signals from these shapers are transmitted, respectively, to the acoustic system 6 and the information display means 7. The computer information processing device 5 also includes means 5.6 for adjusting the signals for simulating the visual situation when the vehicle is moving according to signals changing the position of the head and / or the direction of the learner’s gaze, associated with the shaper 5.5 video signals. The audio signal generator 5.4 is coupled to a vehicle motion simulation tool 5.2 for generating noise simulation signals while the vehicle is in motion. The driver’s workplace 1 is a structure with a driver’s seat on which controls 3, means for determining the position of the latter, information display device 1 and acoustic system 6 are installed 6. The driver’s workplace 1 can be adapted to adapt to a comfortable position of the driver with structural features of the body of the latter. The controls 3 include: steering, brake pedals, gas, clutch, gearbox simulator and gear lever, all these controls are associated with means 2 that control their position. The axes of the means for determining the position of the pedals and the steering wheel are rotated by an angle proportional to the movement of the control. Means of determining Ii: ci / c (l6, the positions of the gear lever and the parking brake are activated when the corresponding control is moved to a certain position.

Each pedal is equipped with a special boot device that creates a feeling of resistance to movement of the foot, corresponding to the resistance in a real car.

The clutch pedal is mechanically connected to the lever in the gearbox simulator in such a way that it is impossible to shift the gear when the clutch lever is not pressed.

The simulator works as follows.

First, testing is carried out, in which the degree of development of motor skills that are professionally significant for Eoditsch is determined. Based on the results obtained, a strategy and tactics for individualizing training are developed. In the mode tested, the simulator testing tool 5.3 provides the selection and registration of each of the tested parameters and their combinations: taxiing speed, gear shifting speed, speed and accuracy of foot movements when pedaling. The simulator in testing mode is as follows. The learner, being at the workplace, at the instruction of the instructor performs certain actions, for example, the rotation of the steering wheel from one stop of the rotary mechanism to another with the maximum possible speed for the learner.

The testing tool includes a software module that processes the signals from the means 2 for determining the position of the controls. If necessary, an analog-to-digital conversion is performed.

Individual vehicle controls are tested programmatically, for example, entering a flyover or passing a certain route for a specific time.

In driving mode, the simulator operates as follows.

in a certain way, depending on the task posed, on the organs of disposition. As a result, the determination means 2 associated with the controls 3 are activated and analog voltages proportional to the amount of movement of the controls are formed at their outputs. Converted to a digital code, they, using a computer, are transformed into the numerical values of the variables proportional to the position of the controls 3 necessary to control the vehicle’s motion model.

The basis of the car’s motion model is made up of differential equations describing the movement of aggregates and units of a real car in interaction with the soil and terrain profile, taking into account a specific car model. Based on these equations, a software module was created that simulates the movement of the machine, which, in combination with a personal computer, makes up a tool 5.2 for motion simulation. As a result of solving differential equations, the values of the output variables of the motion model are calculated, the main ones are:

1. engine torque;

2. engine shaft speed;

3. linear speed of the car;

4. The corner speed of the car;

5. pitch angle of the sprung part of the body;

6. roll angle of the sprung part of the body;

Output variables 1-3 from the simulation tool 5.2 are fed to the inputs of the former 5.4, which is a software module in conjunction with a personal computer, a sound card that converts a digital code into an audio signal and, if necessary, an amplifier to create the necessary noise level. As a result, the learner hears in the headphone of the ILC through the speakers (speaker system 6) installed in the housing of the driver’s workplace 1, engine noise depending on the mode of operation of the simulated machine. On a real machine, noise is recorded in several characteristic modes, for example, starting with a minimally stable engine shaft speed and ending with a maximum one, at regular intervals over the engine shaft speed. Further, the same recording is carried out at a different load on the engine. The result is a finite number of fragments of the recording of the noise in the driver's seat. Then these fragments are digitized on a computer and using the output variables of the motion simulation tool 5.2 these fragments are selected and converted using the sound card into an analog engine noise signal. Intermediate values between the fixed rotational speeds of the motor shaft at which the noise was recorded are interpolated due to the shift of the fundamental frequencies of the spectrum of the digitized noise. Thus, the simulated noise in the inventive simulator almost corresponds to real noise, while the more digitized fragments, the simulated noise is closer to real. Other output variables characterize the movement parameters of the vehicle on the ground. From the means 5.2 they come to the shaper 5.5 video signals. These variables control the position of the simulated vehicle on the ground. The terrain is reproduced programmatically using three-dimensional graphics. Shaper 5.5 includes a database of visual objects, a frame sampling module, and a module (software or hardware) for generating a frame in any standard three-dimensional graphics. A visual database is a set of interconnected named elements of the type LOCATION, OBJECT, IMAGE, ST | ET, TRACES, etc. A visual information display device may be an information display device compatible with a frame generation module or a virtual slit. The frame sampling module, in accordance with the parameters of the terrain selected for training, the position of the simulated vehicle in space, extracts information about the route of the simulated for

site exercises. In addition, this module generates the amount of geometric data necessary for constructing the frame about the terrain, objects and lighting, i.e., those objects and their features that the trained driver should see on the visual information display device. Then, said module transmits this data in accordance with the standard implemented in the frame generation module, and transmits the obtained control sequence to the frame generation module, which forms a frame in the visual information display device.

The output variables arriving at the frame sample module that determine the vehicle’s movement in space from the motion simulation tool 5.2 provide a selection from the visual database of information about the simulated terrain for each new position of the car relative to the terrain. As a result, when “driving a car on the simulator, the trained driver sees a changing terrain on the visual information display device 7. Moreover, the changes that he sees are determined by the spatial position of the simulated car, which depends on what position it puts the controls 3 on and on the characteristics of the car itself, which are embedded in the motion simulation tool 5.2, i.e. the driver controls the vehicle on the simulator in the same way as if he would drive a real car in real terrain.

In this case, the generated image is corrected and the frame is shifted depending on the position of the holoea and / or the learner’s gaze, according to the signals generated in accordance with the information received from the video camera.

The simulated movement of the vehicle on the ground is reproduced taking into account the driver’s impact on the controls installed at workplace 1, depending on the position of the head and / or the learner’s gaze, as well as taking into account variables characterizing the parameters of the weather and road conditions of the moving car.
