Description

The utility model relates to the field of educational and training tools and can be used to teach driving a car and other similar vehicles.

Known driving simulator, which is a model of the driver’s workplace, consisting of a standard driver’s seat with parameter control systems, pedal block, gear lever, parking brake, dashboard with instrument cluster, steering wheel with steering column switch and monitor located behind the instrument panel [one].

The presence of only one monitor and the location of its screen in front of the student at a certain distance leads to the fact that other information, not related to traffic, partially falls into his field of vision. For example, with lateral vision he can see the situation and what is happening in the room where the simulator is installed. In addition, the simulator’s lack of a system for modeling the dynamics of the car’s movement and a dynamic platform does not allow the student to feel the reality of the road situation. All this ultimately does not allow to achieve high quality training on the simulator, since it is significantly different from the driving conditions on a real car.

A tracked vehicle driving simulator is also known, comprising a cabin with controls located on a dynamic platform, a system for simulating the dynamics of a vehicle’s movement, a visual environment simulation system and a noise simulator electrically connected to each other, and the last two, respectively, with a visual information display device and an acoustic system [2].

In a dynamic simulator, vibrations of a dynamic platform (pitch, roll and vertical movement) are carried out using

electric drives and a vertical single-spring support (rack), the upper end of which is connected to the platform through a cardan joint and the lower end is connected to a fixed bed through a spline connection. The dynamic platform of the simulator under consideration has three degrees of freedom, which allows for fluctuations in the payload (cab), which most fully reflects the movement of the vehicle in the area. At the same time, it has a significant drawback - low flexibility of the movable system, which is predetermined by the presence of one spring in its design. To maintain a given value of the payload (cabin weight), the spring must be manufactured with increased stiffness. Such a spring does not provide the required amount of vertical movement of the cab, as a result of which the driver, being at the workplace, does not fully feel the situation of the real situation.

The closest set of essential features to the claimed one is a car driving training simulator, which contains a cabin with simulators of controls similar to the controls of a real car mounted on a mobile platform with three degrees of freedom and visual information display devices (monitors) and an acoustic system located in it , electrically connected and computer-controlled system for simulating the dynamics of a car, including a transmission model with simulated rum gearbox system simulating the visual environment, the band outputs are connected to inputs of display devices visual information, noise simulation module whose output is connected to the input of the speaker system [3]. As the closest in design, this simulator is the closest analogue (prototype) of the inventive simulator for learning to drive a car.

This device partially eliminates the disadvantages, especially those noted in the first analogue. In the simulator there is a system for modeling the dynamics of car movement, including a model

dynamics of the transmission with the gearbox, a dynamic platform has been introduced into the design, which provides the learner with a range of acceleration loads, the location of the monitor behind the dashboard (approaching it to the driver) to some extent reduces the unnecessary information getting into the field of vision of the learner.

However, as in the second analogue, the prototype uses a single-spring dynamic platform, which has the disadvantages described above. The absence of steering loads, depending on the terrain, speed and other factors, an uncontrolled gearbox that allows you to switch to non-adjacent gears (for example, from first to fourth), does not make it possible to instill the correct car driving skills when training on the simulator. The presence of only one monitor and its location at a distance from the driver does not exclude the entry of inadequate information into its field of vision.

In addition, there are such shortcomings as incomplete modeling of the degree of the terrain overview due to the lack of information received by the driver through the rear-view mirrors about the traffic situation behind the car, as well as the lack of video monitoring of the student's actions.

The proposed utility model solves the problem of approximating the training conditions on the simulator to the real conditions of movement of the driver on the simulator.

The expected technical result in the implementation of the utility model is the expansion of the simulator's functionality by modeling additional functions that take place in a real car, and is simulated in the simulator by introducing a device that regulates the correct switching of speeds in the gearbox, a device that changes the steering wheel loads depending on from the terrain, speed and other factors

a dynamic platform is more pliable due to the introduction of two springs concentrically arranged in one another, the arrangement of monitors in the planes of each of the front and side windows of the cab, which allows to increase the degree of field view from the driver's seat, to eliminate the inadequate information from entering the learner's field of vision and provide the learner with information through the rearview mirrors about the traffic situation behind the car. In addition, the location in the cockpit of the camcorder allows the instructor to carry out video monitoring of the student's actions.

To achieve this technical result, a well-known simulator for learning to drive a car, comprising a cabin with simulators of controls similar to the controls of a real car and visual information devices (monitors) and an acoustic system electrically connected to it and installed on a movable platform with three degrees of freedom, a computer-controlled system for simulating the dynamics of vehicle motion, including a transmission model with a gearbox simulator, a simulation system and the visual environment, the group of outputs of which is connected to the inputs of the visual information display devices, the noise simulation module, the output of which is connected to the input of the speaker system, additionally contains a steering load simulator with a steering wheel, a gear shift control device and a video camera for video monitoring of actions installed inside the cab learner, monitors are located in the planes of each of the front and side windows of the cabin, and the movable platform is mounted on a dynamic a spring, spring-loaded by two springs concentrically arranged one in the other, while the springs have different lengths and different winding pitch.

Distinctive features of the claimed simulator from the closest analogue are the presence of a steering load simulator with a steering wheel, a gear shift control device,

a video camera installed inside the cabin, as well as the location of the monitors in the planes of each of the front and side windows of the cabin and the installation of a dynamic support on a spring loaded by two concentrically arranged one in the other, springs having different lengths and different winding pitch.

Due to the presence of these features in the design of the inventive simulator, the product’s functionality expanded, the technical result described above was achieved, which ultimately made it possible to solve the problem and bring the training conditions on the simulator closer to the conditions of movement of a real vehicle (car).

The proposed simulator for driving training is illustrated by the presented diagram.

The simulator (see diagram) contains a cabin 1 mounted on a movable platform 2 (on its countertop). In the cabin 1 controls are placed 3, visual information display devices (monitors) 4, an acoustic system 5. The simulator also contains an electrically connected and controlled from a computer 6 system for simulating the dynamics of a vehicle 7, including a transmission model 8 with a transmission simulator 9 connected to gearbox control device 10, steering load simulator 11 connected to steering wheel drive 12, visual environment simulation system 13 connected to visual display device information 4 of the cabin and the instructor’s monitor 14, a noise simulation module 15 connected to the speaker system 5. A video camera 16 is installed inside the cabin for video monitoring of the student’s actions, information from which is transmitted through the visual environment simulator 13 to the instructor’s monitor 14. The table of the dynamic support 2 is mounted on the dynamic stand 17, which is spring loaded by two springs 18 and 19 concentrically arranged in one another, having different lengths and different winding pitch. Information display devices (monitors) 4 are located in

the planes of each of the windshields and side windows of the cab 1.

The steering wheel drive 12 is (as an option) an electric motor that rotates the steering axis through a chain drive gearbox, simulating various reactions that occur during the movement of a real car.

The gearbox shift control device 10 is (as an option) a computer-controlled electromagnetic clutch that locks the gear lever in case of learner malfunctions, for example, when trying to switch to non-adjacent gears (from first to third and subsequent), or gears without resetting engine speed.

The work of the simulator for learning to drive a car is as follows.

The instructor turns on the simulator and, with the help of a computer, sets the task for the trainee in the cabin. The subject of the current task appears in front of the student on the front monitor.

Upon receipt of the task of movement on a given terrain, the student starts the engine and, acting on the controls, carries out movement. At the same time, due to the presence of an electrically connected and computer-controlled system for simulating the dynamics of the car 7, a system for simulating the visual environment 13, a noise simulator module 15, a steering loads simulator 11 and a gearbox simulator 9 in the simulator, all systems and assemblies taking place in real car. On the screens of visual information display devices (monitors) 4 and 14, the landscape of the terrain on which the movement is carried out is reproduced, and with the help of the acoustic system 5, the student hears the noise of the engine and other units of the car.

The location of the monitors 4 in the planes of each of the front and side windows of the cab 1 completely eliminates getting into the driver’s field of vision

extraneous visual information. In this case, the driver perceives only the information that, according to a pre-recorded computer program, is transmitted to the monitors from the visual environment simulator. In addition, the installation of monitors in the planes of the side windows and the features of the visual environment simulation system 13 make it possible to combine information on the side monitors about the traffic situation on the side and behind the car received by the driver in a real car from rear-view mirrors.

The introduction into the cabin 1 of the surveillance camera 16 allows video monitoring of the student’s actions with the transfer of information to the instructor’s monitor 14.

Dynamic platform 2 of the simulator provides the movement of the cabin 1 with three degrees of freedom (roll, pitch and vertical movement), which most fully displays the movement of a wheeled vehicle in the area. These movements are carried out with the help of three electric drives and a movable dynamic support (rack) 17, which is spring-loaded with two springs 18 and 19 concentrically arranged in one another, having different lengths and different winding pitch. When applying control signals from the control unit to the drives, they move the cab 1 through the crank-axial mechanisms. The spring-loaded support 17, using two springs 18 and 19 concentrically arranged in one another, having different lengths and winding pitch, gives greater flexibility to the movable system for due to less rigid springs and their consistent operation (compression). This allows you to achieve the magnitude of the vertical displacements adequate to the displacements taking place in a real car.

One of the most important devices that convey to the driver the feeling of the supporting surface of the landscape is the steering wheel. Throughout the entire driving route, the driver constantly monitors his behavior and, depending on the traffic situation received through the simulator

visual environment, decides on the next action.

The sum of the steering reactions to the driver gives him a large amount of sensory information, namely: speed, the difference in ground coatings under the front wheels, the presence of micro and macro-irregularities. To reproduce these reactions in the simulator, it is equipped with a steering load simulator 11 and a steering wheel 12 that reproduces the corresponding steering reactions that are adequate to the reactions that occur in a real car during its movement.

Reproduction of the aforementioned reactions by the steering load simulator is carried out from the rudder state sensor, which generates certain signals corresponding to the indicated reactions. These signals are transmitted through the computer to the executive body of the simulator - the electric motor, which through the gearbox of the chain transmission rotates the axis of the steering wheel, simulating the above reactions.

An important structural element that affects the development of the right driving skills is also the gearbox. The correct sequence of gear shifting: the sequence of switching on one or another gear, the possibility of shifting to a lower gear depending on the engine speed, develop the necessary skills for driving the student. For this, the simulator is equipped with a gear shifting control device 10. Such a device is a computer-controlled electromagnetic clutch. Receiving the corresponding signals recorded in the program, it blocks the driver’s wrong actions, that is, it does not allow, for example, switching to non-adjacent gears (from first to third and subsequent), switching speeds without resetting the engine speed.

All this brings training conditions on the simulator closer to driving conditions on a real car.

Thus, the proposed utility model is achieved

expanding the simulator's functionality by modeling additional functions that take place in a real car, which brings training conditions on the simulator closer to the real conditions of the driver’s movement on a wheeled vehicle.

Declared as a utility model, a simulator for learning to drive a car can be manufactured in mass production at any machine-building enterprise using domestic and foreign materials and components.
