Description

A SIMULATION APPARATUS HAVING A FUNCTION OF GUIDING USER'S CONTROLLING BEHAVIOR

Technical Field

The present invention relates to a simulation apparatus, and more particularly, a simulation apparatus having a function of guiding user's controlling behavior that can

improve reality and simulation effect by guiding user's operation by bodily sensation of acceleration change and generating unbalance.

Background Art

Generally, a simulation apparatus executes a computer program for outputting images according to a simulation image and a control data on a computer, projects images applied in a corresponding simulation program on a screen, recognizes operation of user's controller such as a steering controller, a speed controller, and others, and converts image in images projected on the screen according to operation of user's controller. Like this, the simulation apparatus provides an effect that the user feels like operating actual devices, and accordingly, makes it possible for user to play a virtual reality game or to practice driving of an automobile, an airplane, and others, by providing sense like driving actually an automobile, a motorcycle, an airplane, and others, to the user.

FIG. 1 is a diagram illustrating a conventional simulation apparatus for driving an automobile.

The conventional simulation apparatus for driving the automobile comprises a booth including display screen for outputting simulation images and a steering device that are located at the front surface thereof, a seat for user, and an acceleration controller such as a brake for controlling acceleration and an acceleration pedal that are provided on the front surface of the bottom of the seat. A computer to drive simulation program data for driving the automobile is generally located inside the booth or the seat to control function of the simulation apparatus for driving the automobile. In other words, in the conventional simulation apparatus for driving the automobile, an internal computer receives signals inputted from the steering device and the acceleration controller by a user and outputs the screen images related to various course built in the program according to user's operation, thereby providing an effect that the user feels like driving actually. Further, when the course is undulated surface, the seat is vibrated, and when the course is a curve road, the seat is fluctuated in horizontal direction so that the reality is more improved.

However, the conventional simulation apparatus such as the simulation apparatus for driving the automobile of FIG 1 produces the following problems.

First, the cost for graphics is too much generated because the computer recognizes the user's driving operation and then converts a driving mode corresponding to the operation to images.

Second, because only images captured by an angle of camera fixedly installed at the position of eyes of the driver are outputted, the user can feel reality only in straight highway or a gentle curve without much inclined disappearing point, but there is a

problem that a viewing angle is limited in a sharp curve.

Third, the conventional simulation apparatus stimulates body senses of the user by vibrations and change of tilt, but because the simulation apparatus is fixed on 2-dimensional plane, it provides only simple vibration, or change of tilt and cannot generate changes of gravity and inertia more than the user's weight. Accordingly, there is a problem that although the user can feel an instant posture change, the user cannot feel

continuous inertia operation like as actual driving. That is, because the conventional simulation apparatus cannot provides sense of tension or gravity (G: sense of inertia, sense of acceleration) applied to muscles and blood vessels of the user and continuous sense of gravity more than user's weight, it cannot provides sense of operation like actual operation, but provides only sense of passenger's position. Accordingly, there is a problem that education efficiency becomes low.

Fourth, in the conventional simulation apparatus, because transmission is performed based on a speed value calculated after a certain acceleration course differently from actual driving at the time of shift course by a clutch and the like, the user is not provided with sense of acceleration change according to operation of the clutch. As a result, there is a problem that the user cannot bodily sense a driving technique like shift timing.

Fifth, in the conventional simulation apparatus, because only inertial reactions according to the user's operations like as stimulating the user by an optical illusion of screen images, fragmentary vibrations or tilt changes according to the user's operations are expressed, the user cannot feel sense of resistance caused by an inertial reaction for stimulating the three semicircular canals maintaining sense of equilibrium of the user. That is, there is a problem that the stimulator provides merely bodily senses of passenger's position, and accordingly cannot express the sense of equilibrium caused by user's sense of driving.

That is, the problems of the conventional simulation apparatus enable the user to lose reality during the operation of the simulation apparatus, thereby causing dizziness or motion sickness. Therefore, because the simulation apparatus cannot reflect the motion of the device to be actually driven, the sense of reality about the simulation apparatus is

reduced, thereby allowing the education efficiency of actual operations to be prominently decreased.

Disclosure of Invention

Technical Problem

The present invention has been suggested to solve the above-mentioned problems, and an objective of the present invention is to provide a simulation apparatus having a function of guiding user's controlling behavior, that can maximize virtual reality for a motorcycle, a ship, an airplane and a playing apparatus by stimulating sensory organs of equilibrium such as three semicircular canals so that a user can feel senses of position change and continuous acceleration change like actual driving of a simulation object device, when the user plays a game or receives a training using the simulation apparatus by applying 3 -dimensional acceleration change effect caused by a gyro effect, a centrifugal force effect and the like, and that can receive an actual driving training by guiding the user's operation by stimulating the sensory organs of equilibrium.

In other words, the objective of the present invention is to provide a simulation apparatus having a function of guiding user's controlling behavior, that can maximize the simulation effect by providing a simulator on a device that performs a horizontal rotating movement to reproduce a reaction of gravity (acceleration, inertial force) during running and a direction of the reaction of the gravity, so that the user can bodily sensing gravity (acceleration, inertial force) by using centrifugal force and sense inertial forces (gravity, acceleration) leaning phenomenon applied in all directions, and simultaneously bodily sensing resistance force to inertia corresponding to the user's controlling behavior (driving operation) by changing applied inertial force or degree of tilt.

Best Mode for Carrying Out the Invention

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing. The aspects and features of the present invention and methods for achieving the aspects and features will be apparent by referring to the embodiments to be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed hereinafter, but can be implemented in diverse forms. The matters defined in the description, such as the detailed construction and elements, are nothing but specific details provided to assist those of ordinary skill in the art in a comprehensive understanding of the invention, and the present invention is only defined within the scope of the appended claims. In the entire description of the present invention,

the same drawing reference numerals are used for the same elements across various figures.

FIG. 2 shows a construction of a simulation apparatus for driving an automobile having a function of guiding user's controlling behavior according to one exemplary embodiment of the present invention.

Referring to FIG. 2, the simulation apparatus for driving the automobile includes

a centrifugal force providing unit 1 configured to provide a continuous acceleration effect by centrifugal force to the user, and a horizontal rotation unit 10 provided in the centrifugal force providing unit 1 to convert the direction of acceleration of the user. A pitching unit 14 is installed above the horizontal rotation unit 10 and the tilt of the pitching unit 14 is changed by rotation in front and rear direction on the horizontal rotation unit. A rolling unit 19 is installed at the pitching unit 14 so as to be vibrated in a direction orthogonal to the rotation direction in front and rear direction. A cockpit unit 30 is seated inside the rolling unit 19 for controlling simulation. A computer device or program board (not shown) as a controller is mounted on the cockpit unit 30 or a base 6 of the centrifugal force providing unit 1. The controller outputs a control signal for a simulation operation to control each element of the simulation apparatus and controls the simulation apparatus according the user's operating control signal. The centrifugal force providing unit 1 includes a rotating plate 45 that is rotated by driving force transferred by a rotation driving motor 2 and a gear train 3, a multi-stage rod 5 connected to a rotating axis 4 to move circularly, a pitching unit 14 mounted on an end part of the multi-stage rod 5 to provide an acceleration effect by centrifugal force to the user by rotating by the rotating plate and a base 6 provided with a rolling unit 19 including a cockpit unit 30 installed inside.

Next, referring to FIGS. 3 to 9, the construction and combination relationships of each element will be explained in detail.

FIG. 3 shows a detailed construction of the multi-stage rod 5 and the base 6 of the centrifugal force providing unit 1.

The base 6 is fixed at the end of the multi-stage rod. An air jack 7 configured to change the length of the multi-stage rod 5 is coupled with a terminal rod of the

multi-stage rod inside the base 6. The air jack 7 includes an air tank 8 provided with an air compressor 9 to inject air and an air controller 8a configured to control flow-pressure of air flowing from the air tank 8 to the air jack 7. The air jack 7 changes the length of the multi-stage rod 5 by the air controller 8a according to a control command from the computer device or the program board for controlling the simulation apparatus. Accordingly, the centrifugal force is controlled so that the user feels the reaction and change of acceleration (or gravity). FIG. 4 shows combination of a horizontal rotation unit 10 and the pitching unit 14 mounted on the base 6 of the centrifugal force providing unit 1, and FIG. 5 shows a detailed construction of the horizontal rotation unit 10, the pitching unit 14, the rolling unit 19 and the cockpit unit 30.

Referring to FIG. 4, the horizontal rotation unit 10 is mounted on the base 6 having the construction of FIG. 3. The horizontal rotation unit 10 reverses the direction of acceleration (force) applied to the user by rotating the position of the user to the direction of the centrifugal force supplied from the centrifugal force providing unit 1 by rotating the pitching unit 14 in horizontal direction. The pitching unit 14 is combined to the upper part of the horizontal rotation unit 10. The pitching unit 14 guides the user's operation of

acceleration and deceleration by controlling tilt in front and rear direction of the user by rotating on the line of acceleration by centrifugal force.

The horizontal rotation unit 10 is fixed to the upper part of the base 6 rotatably in horizontal direction. The horizontal rotation unit 10 includes a horizontal rotation gear 11 provided with a gear formed on its circumferential surface and a horizontal rotation motor 13 provided with a gear 12 formed at its axis part and combined with the horizontal rotation gear 11. The horizontal rotation motor 13 rotates the horizontal rotation gear 11 to change the direction that the user bodily senses acceleration by the centrifugal force provided by the centrifugal force providing unit 1 driven by the computer device or program board.

A pitching motor 15 combined with the upper part of the horizontal rotation unit 10, a pitching gear 16 rotated by the pitching motor 15 and a rack gear to be rotated in front and rear direction by the pitching gear 16 are formed on the upper face of the horizontal rotation gear 11. The rolling unit 19 includes an arc shape pitching frame 17 to be coupled by a rolling axis 20 rollably in the direction vertical to the front and rear direction of the pitching unit 14 and a pitching roller 18 to be installed on the upper face of the horizontal rotation gear 11 for guiding smoothly the rotation of the pitching frame in front and rear direction at the lower part of the pitching frame 17. The rolling unit and the pitching unit provide effects of changing the direction and value of acceleration and balance by a rotation and rolling movement like as gyro movement.

The pitching unit 14 rotates the pitching gear 16 by the pitching motor 15 under the control of the computer or program board, changes the balance in front and rear direction of the user, and guides the user's acceleration or deceleration operation by rotating the pitching frame 17 on the upper face of the horizontal rotation gear 11. The user performs acceleration or deceleration operation according to the change of tilt in front and rear direction and senses bodily the balance against the centrifugal force.

The rolling axis 20 is rotatably coupled to each of both ends of the pitching frame 17 of the pitching unit 14. A screen basket 22 is combined with the rolling axis 20 so as to be vibrated in right and left direction by the rolling axis 20 on the line of the pitching frame 17.

The screen basket 22 is supported by an annular type rolling frame 21 in which two rolling axis 20 are fixedly coupled to both ends of the rolling frame 21 and a rack gear is formed on outer circumference surface. The screen basket 22 is seated on the rolling frame by a rolling unit guider 22a so as to cover the rolling frame at the outer circumference surface corresponding to the rolling frame. Two slip rails 25 are formed at the upper part of the rolling unit guider 22a, and a weight slipper 23 is mounted on each slip rail 25 so as to move on the slip rail 25 by a slip motor 24. The movement of the weight slipper 23 enables the screen basket 22 to be tilt about the rolling axis 20 of the pitching frame so that the user feels tilt in right and left direction, thereby guiding the steering operation of the user.

A yawing motor 26 is attached to outside of the screen basket 22. The yawing motor 26 is provided with a yawing gear engaging with the rack gear formed on the outer circumference of the rolling frame 210. The yawing motor 26 rotates the screen basket 22 on the rolling frame 21. The yawing motor 21 is preferably configured to be radically located with a certain spaced angle in even number so as to provide always a bilaterally symmetrical weight for maintaining equilibrium state according to rotation of the screen basket 22. When the screen basket 22 is rotated on the rolling frame 21 by steering wheel, the user's sensible direction of acceleration applied by the centrifugal force providing unit 1 is changed. A cockpit unit fitting groove 27 is formed with a predetermined length on a bottom face inside the screen basket 22 and position sensors 28 are arranged on both sides of the fitting groove 27. The FIG. 6 shows a detailed construction of the cockpit unit 30.

Referring to FIG. 6, the cockpit unit 30 includes a cockpit 31 including a steering device 32 and an acceleration controller 33 constituted of a clutch pedal 33a, a brake pedal 33b and an accelerator pedal 33 c. The cockpit unit 30 includes a cockpit air jack 37 between an image projector control panel and the cockpit. The air jack 37 produces impacts caused by slope and undulated surface to the cockpit. A vibrator 35 is provided for the back supporter of the cockpit to provide the effect according to RPM of an engine, and a wind duct 32a as an air sprayer is provided on an upper part of the steering device 32 to provide the more real effect of sensing speed.

The cockpit unit 30 is provided with an effect sound speaker. The image projector control panel 38 is installed at the lower part of the cockpit 31 and is coupled so as to rotate on the outer circumference surface of the cockpit independently from the cockpit 31 by an image projecting direction control motor 39. An image projector 41 is installed above the cockpit 31 and projects a simulation image inside the screen basket 22 of the rolling unit 19 by a support frame 40 extended from the image projector control panel 38. A center moving device 43 is provided below the image projector control panel 38 and moves the center of the cockpit in front and rear direction along the longitudinal direction of the cockpit unit fitting groove 27 formed on bottom face of the screen basket 22, and includes a linear motor movable along a magnet rail 44 shown in FIG. 19. FIG. 7 shows reaction according to each pedal operation of a center moving

device 43 operated by the driving force of the linear motor.

FIG. 8 shows a reaction according to a clutch pedal interruption. The pressurization of the clutch pedal is performed by turning off the power supply of a linear motor to reproduce an effect of coasting when the power supply is turned off in actual driving. In this time, because the cockpit is located on the rotating plate, the total weight of the cockpit can be prevented from being restored to the direction of gravity by centrifugal force during a certain time. When the linear motor is turn on, in other words, when the clutch pedal is depressurized, a volume effect for controlling the voltage to an electromagnet is provided for a smooth power transmission. FIG. 9 shows difference between a driving force and a restoring force according to the position of each gear of the center moving device 43, and more particularly, the linear motor in the center moving device generates magnetic force corresponding to the pressurizing force of the accelerator pedal to move the cockpit along the magnet rail, and at the time of depressurization, the linear motor restores the cockpit along the magnet rail according to the amount of depressurization of the pedal.

In this time, a moving distance and a restoring distance of the cockpit driven by the magnetic force of the linear motor are longer in a low speed gear than in a high speed gear. The difference between the low speed gear and the high speed gear is based on a shift ratio (a gear ration) in an actual automobile engine. In addition, a central gear restored at the time of depressurization of the accelerator pedal is faster than a restoring speed at the time of coasting. This means that the magnetic force for restoration should be stronger than the centrifugal force, and the restoration property of the accelerator pedal is to express an engine brake phenomenon occurring when the acceleration pedal is depressurized during accelerating in actual driving.

Referring to FIG. 9, each of references (a), (b) and (c) represents driving force according to each gear position, and more particularly, represents the position of the center moving device under the condition that the acceleration pedal is not pressurized. This reflects rpm of the engine in an idling state of an actual automobile.

The image projector control panel guides the user's eyesight corresponding to a curve section and thus guides the user's steering operation by rotating so that a projection image of the image projector tilts at a certain angle in the direction of the curve from the center of the seat at the time of projecting the image of the curve section. The simulation apparatus for driving an automobile provides reality by providing eyesight guiding, rotation guiding, acceleration / deceleration guiding, gear shift guiding (shift guiding), sense of gravity (G : gravity), sense of acceleration, sense of deceleration and sense of inertia.

The eyesight guiding means that an image is projected in the direction of guiding the user's eyesight so as to be a reference point to the user's sense of balance and an image effect is provided according to an improper or proper operation of the steering device and the acceleration device.

The rotation guiding means that an instinctive action is guided to maintain respondent equilibrium by providing unbalance that the user is tilted to one side. This rotation guiding is used for training of controlling the steering device and the acceleration device together with the eyesight guiding.

The acceleration guiding means that the user is guided to operate the acceleration pedal by providing sense of tilting backward about the balance state of the user. The deceleration guiding in opposite to the acceleration guiding, means that the user is guided to depressurize a throttle or operate a brake pedal by providing an emergency situation about the balance state like as sense of tilting forward.

The gear shift guiding means that gear shift is guided by making the user sense that more movement of the center (acceleration) is impossible as well as that the power is short or the noise of engine is stressful with an image effect.

That is, the simulation apparatus for driving an automobile provides the user with

sense of continuous acceleration change by the centrifugal force providing unit 1, stimulates the user's sense of equilibrium by the horizontal rotation unit 10, the pitching unit 14 and the rolling unit 19, and provides the user with the eyesight guiding, the rotation guiding, the acceleration / deceleration guiding, the gear shift guiding (shift guiding), the sense of gravity (G : gravity), the sense of acceleration and the sense of deceleration by displaying an improper or proper operation state by position change of the projected image of the image projector and the image effect to guide the user's driving operations and provide the simulation effect like as an actual driving. Hereinafter, the operation of the simulation apparatus for driving an automobile of FIGS. 2 to 9 will be explained in detail with reference to the attached drawings.

FIG. 10 shows the user's senses at the time of curve driving in the simulation apparatus, and FIG. 11 shows operation for guiding the user's driving operation by guiding the user's eyesight in the moving direction in the simulation apparatus of FIGS. 2 to 9, and FIG. 12 shows one example of visual effects according to an improper or proper driving operation.

Referring to FIG. 10, (a) shows a limited field-of-view of the user in the conventional simulation apparatus, and (b) shows space perception effect about turning radius according to the movement of the user's view at the time of curve driving, and (c) shows it is possible that a preceding driver may guide the user's eyesight to the moving direction for guiding the user's driving operation.

Generally, when the driving course is a curve section, the user operates a steering wheel in the moving direction after the user has changed his/her eyesight to the moving direction. After the automobile is started to run by the steering wheel operation, the effect like as driving with wider field-of-view than user's eyesight is provided because of an afterimage about the moving path remained in the user's brain.

However, in the conventional simulation apparatus, the user's eyesight is concentrated to one point as shown in FIG. 10a. Accordingly, in case of the curve driving, the user cannot look the road in forward direction in advance before the user (driver of the simulation apparatus) rotates the steering device (wheel) 32 to the moving direction.

Accordingly, in the simulation apparatus of the present invention, when the user performs a simulation of the curve driving, the image projector control panel 38 (shown in FIG. 6) is rotated to the moving direction of the curve way by driving the image projecting direction control motor 39 (shown in FIG. 6) by a computer or program board of the simulation apparatus, and simultaneously the image rotated by the image projector 10 is projected inside the screen basket 22. At the time of curve driving as shown in FIG. 11, if the image of way in the moving direction is projected in advance at the position inclined to the user's moving direction, the user turns his/her eyesight to the moving direction and accordingly, the afterimage about driving environment can be maintained and the moving direction is perceived as an actual curve way so that the user is guided to turn the steering wheel to the moving direction. Here, the image projection position in the moving direction of the image projector may be set to the image position in the direction of the user's eyesight at the time of most general curve driving by investigating experimentally the user's driving habit.

The user's ability of driving operation can be improved by changing visual effect about the projected image according to the case that the user's driving operation is properly conducted or improperly conducted after the user's driving operation has been guided by the operation of FIG. 11. In this case, the proper or improper operation of the acceleration pedal, the brake pedal and the clutch pedal may be considered.

FIG. 12 shows one example of visual effect according to a proper driving operation and an improper driving operation according to the user's control of the steering wheel and the acceleration device. Particularly, if the speed exceeds a normal speed by an excessive pedal operation, the screen becomes dark so that the user recognizes the over-speed. FIG. 12b shows a projection image at the time of proper operation, and in this case, the image of the moving direction is outputted without any visual effect. FIG. 12c shows a visual effect in case of the speed below the normal speed, and in this case, the screen is blurred. FIG. 12d shows one example of a visual effect in the case where the improper steering operation has occurred, and the user is guided to recognize the improper steering operation by outputting image so as to make the user feel like that the same images are overlapped and separated. The visual effects of the FIG. 12 are just only illustrations for one example of the visual effect of the present invention but not limited thereto. The characteristic of the visual effect will be explained. Because the driving modes like the improper operation or excessive operation in actual driving are caused by recognizing the road situation in short and narrow field-of-view of the user, the same motions as the actual driving can be guided by providing the eyesight movement for inducing the user's uneasiness or the program like as the inclined images. Accordingly, the simulation apparatus for driving an automobile provides the image as a reference point of balance that provides the user with a target view differently from the conventional simulation apparatus that produces the images in the moving direction. That is, the visual image applied to the present invention is singular number of driving mode image in which an accident or a field-of-view in uneasy condition is programmed together. Accordingly, the visual image is the image that provides the user with the target and the reference point, i.e., the image to guide the user's eyesight for guiding the

operation.

This provides the solution to the problem that the conventional simulation apparatus could not provide the eyesight movement required in case of a sharp curve or U-turn in which the user should turn his/her neck by only fixed image of front direction. In this time, the image projector is preferably a scan direction variable type beam projector so as to overcome the limits of the user's eyesight guiding function and field-of-view. Next, in case of perspective guiding, because the user's balance state is reflected, the beginning user could not see so far even though the beginner tries to that. Accordingly, in case of right / left guiding, the perspective of the user's field-of-view and the right / left view movement are guided. That is, it is expressed that the state is a balance state where the user feels easy to see far or an uneasy state which the driver feels uneasy not to see far. Considering this, by dimming out the light source of the outputted screen or out of focusing or providing digital effects such as zoom-in or zoom-out by a position sensor, the user (the beginner) can monitor by himself/herself the operation state that the movement state of the center of the cockpit is the position of an optimum balance.

Next, FIG. 13 is a schematic view of the pitching unit 14 and the rolling unit 19 showing the rolling of the rolling unit 19 for providing the rotation guiding, the acceleration / deceleration guiding, the gear shift guiding (shift guiding), the sense of gravity (G : gravity), the sense of acceleration, the sense of deceleration and the like. FIG. 14 shows a left / right balance control of the user by the operation of the rolling unit 19, and FIG. 15 shows guiding the steering operation by the operation of the rolling unit 19.

Referring to FIGS. 13 and 14, the rolling unit 19 that is coupled to the pitching unit 14 rollably about the pitching frame 17 (pitching axis) breaks the left / right equilibrium state by movement of two weight slippers 23 moved on the rolling unit guider 25 by the slip motor. That is, the rolling unit 19 tilts as shown in FIG. 14 by the movement of the weight slipper 23 so that the user becomes to sense unbalance of the left / right equilibrium state in the range of the rolling angle.

The user's sense of unbalance of the left / right equilibrium enables the user to operate the steering device with a provided image. That is, under the balance state as

shown in FIG. 15a, if the right weight slipper 23 is moved to the position of "^~i " on the

rolling unit guider 25 as shown in FIG. 15b, the screen basket 22 tilts to the left to lead the user to tilt to the left. In this time, the user turns the steering device to the right, and continues the steering operation until the screen basket becomes in horizontal balance by driving the yawing motor according to the manipulated amount of the steering device and the screen basket is rotated to locate the two weight slippers to be bilaterally symmetrical about the rolling axis. As a result thereof, the user feels the sense of left / right balance.

Next, the left weight slipper 23 is restored to the initial position by the computer or program board for guiding restoration of the steering operation. In this case, the screen basket 22 tilts to the right, and thus the user turns the steering device to the left to maintain the screen basket 22 in horizontal balance, and finally the cornering is finished and a straight movement is restored.

The eyesight guiding and image effect by the image projector of FIGS. 10 to 12 and the rolling unit 19 of FIGS. 13 to 15 are operated together so that the guiding operation of the steering device according to the curve driving is performed more really.

FIG. 16 shows eyesight guiding for guiding an operation of the steering device in curve driving and movement of weight slippers 23 of the rolling unit 19.

The operation of the steering device will be explained referring to FIG. 16.

Referring to FIG. 16a, at the time of turning in the right-hand curved road, the image

projector 41 is rotated to the position of " ^~i " to project an image of the moving direction

to the right side of the user inside the screen basket 22 to guide the user's eyesight to the right. In this time, the right weight slipper 23 of the rolling unit guider 22a (shown in FIG.

5) is moved to the position of "^L" and located as shown in FIG. 16b. In this time, the

cockpit tilts to the left as shown in FIG. 14a, but because the user has already recognized the corner situation by visual effect of image, the user turns the steering device 32 to the right with uneasiness for balance state. Accordingly, the screen basket 22 is rotated by manipulated amount of the steering wheel by the yawing motor so that the left and right weight slippers 23 are located to be symmetrical on the rolling axis. In this time, the projecting direction of the image is moved because the cockpit and the image projector are moved together by the rotation of the screen basket 22.

Next, in case of turning in a straight road under the situation that the right turn operation has been completed, the right weight slipper 23 is moved to the position of

"u " (initial position) by the computer or program board for restoration of the steering

device (wheel) 32 so that the user is tilted to the right by tilting the screen basket 22. Therefore, if the user turns the steering device to the left, the two weight slippers 23 are restored to the initial position by rotation of the screen basket 22. Accordingly, the screen basket 22 becomes horizontally balanced and the image of a straight road is projected at the front of the user's eyesight inside the screen basket 22 to lead the user to drive in straight road. By this process, the user simulating the curve driving is guided to the restoring operation of the steering device according to turning in the straight road.

The processes for guiding the user's steering operation in FIGS. 10 to 16 can provide the user of the simulation apparatus with better reality by providing the sense of acceleration and the space perception by rotation of the screen basket 22 on the rolling frame 21 by the centrifugal force providing unit 1, the horizontal rotation unit 10 and the rolling motor 25.

FIG. 17 shows process for controlling an acceleration change about the sense of acceleration that the user feels. In the case where the user turns to the right, as shown in FIG. 17a, the screen basket 22 is rotated by driving the yawing motor 26 with the steering operation so that the user is pulled to the left by the centrifugal force provided by the centrifugal force providing unit 1. In the case where the user turns to the left, as shown in FIG. 17b, the screen basket 22 is rotated so that the user is pulled to the right by the centrifugal force provided by the centrifugal force providing unit 1. By this process, the user receiving training of curve driving feels more real sense of driving. FIG. 17c shows a process for reproducing the inertia reaction caused by road friction force on a sudden

braking by rotating the screen basket by 180 degrees. In this time, the rotation is caused by operation of the horizontal rotation unit.

The simulation apparatus is driven not by the user's operation but by help of start program that is called "assist mode." FIG. 18 shows the change of balance that the user feels in case of the assist mode, that is, the procedure that a stable equilibrium state is converted to a dynamic equilibrium state in comparison with a water cup.

The completion of the assist mode means beginning of a main program. However,

the user reacts to various stimulations interrupting the equilibrium because of the instinct for maintaining sense of equilibrium in the assist mode.

FIG. 20 shows a procedure of elongating the axis for increasing the centrifugal force according to the user's acceleration operation.

In the case of being accelerated in simulation operating (controlling the pressurization of the acceleration pedal), the user tilts forward by moving the cockpit unit 30 located in the cockpit unit fitting groove 27 with driving force of a second center moving device. Accordingly, the user feels a sense of resistance to the centrifugal force and thus, the user feels the sense of inertia (the sense of acceleration) according to acceleration movement. In addition, to increase the effect of sense of speed in the acceleration operation, the multi-stage rod 5 of the centrifugal force providing unit 1 is elongated longer by the computer or program board of the simulation apparatus so as to increase the centrifugal force from the centrifugal force providing unit 1 so that the user feels more strong sense of speed. In this time, the length of the multi-stage rod is changed so as to provide an proper centrifugal force by sensing the position of the cockpit unit 30 (the moving distance of the cockpit unit 30 inside the cockpit unit fitting groove 27) by the position sensors 28 and accordingly driving the air jack 7 by controlling an air pressure with the air controller 8a as shown in FIG. 20.

According to the present invention, unbalance for providing the sense of deceleration and the sense of deceleration are provided in addition to the control for the sense of acceleration as described above.

FIG. 21 shows movement state of the cockpit unit 30 according to the user's deceleration operation in a deceleration procedure and FIG. 22 shows operation state of the cockpit unit 30 and the centrifugal force providing unit 1 according to the deceleration procedure. Referring to FIG. 21, when the deceleration operation is performed by pressurizing a brake pedal 33b by the user, the linear motor of the center moving device 43 moves along the magnet rail and the sense of balance that the user feels in this case is compared to a water cup. In this case, the multi-stage rod 5 is contracted by controlling the air controller 8a by the computer or program board of the simulation apparatus according to the user's deceleration operation so that the centrifugal force of the multi-stage rod is decreased to provide more effective sense of deceleration. In the case where the cockpit unit 30 is forwardly moved to a certain point, the pitching unit 14 and the rolling unit 19 are rotated by 180 degrees together by rotating the horizontal rotation gear 11 of the horizontal rotation unit 10 so that the centrifugal force acts to the direction of the user 's back to maximize the deceleration effect.

FIG. 22 shows one example that the deceleration procedure of FIG. 21 has been applied to each position of the position sensor.

Referring to FIG. 22a, when the deceleration operation is performed by pressurization of the brake pedal under the state that the cockpit unit 30 has been located at a position "D" in normal driving state, the length of the multi-stage rod 5 is shortened so as to decrease the sensible inertia that the user feels about his/her back.

FIG. 22b shows the state that the cockpit unit 30 has been backwardly moved to be located at a position "F" (the position of position sensor) according to the acceleration procedure. In this case, the effect of the sense of acceleration is improved by elongating the multi-stage rod 5.

Next, referring to FIG. 22c, in the case where the cockpit unit 30 has been located at a position "A" position sensor, the user's position is rotated by 180 degrees from horizontal direction by rotating the pitching unit 14 by driving the horizontal rotation unit 10 so that the centrifugal force acts to the direction opposite to the user to increase the effect of the sense of deceleration. In this time, when the cockpit unit 30 goes out of the position "A", the horizontal rotation gear 11 of the horizontal rotation unit 10 is rotated by 180 degrees more and thus the rotated seat is restored to the original position.

In the acceleration and deceleration operations, the detected position value by the position sensor is used to maximize the acceleration / deceleration effect by controlling power of wind ejected through a wind duct 32a of the cockpit unit 30.

Next, the user's controlling behavior for acceleration / deceleration can be guided by controlling the pitching unit 14 of the simulation apparatus of FIG. 2.

FIG. 23 shows a procedure for guiding the user's acceleration / deceleration operation by the operation of the pitching unit 14 and the center moving device 43 of the cockpit unit 32.

Referring to FIG. 23a, the cockpit unit 30 is tilted backward by rolling the pitching unit 14 in forward direction by driving the pitching motor 15 of the pitching unit. Accordingly, the user's balance in equilibrium state of driving at a constant speed is broken. Accordingly, the user is tilted backward and simultaneously feels the sense of low speed together with visual stimulus by image to be guided to operate the acceleration pedal.

If the user operates the acceleration pedal 33a, the multi-stage rod 5 is elongated as shown in FIG. 23b and the centrifugal force is increased, thereby allowing the user to sense bodily the speed.

FIG. 23 c shows rotation of the pitching motor for guiding the deceleration by breaking the user's equilibrium state during acceleration and change of pitching angle caused by the rotation of the pitching motor. Further, the user is guided to the deceleration operation by recognizing the visual effect of image provided in this time and the sense of excessive acceleration.

Next, if the user pressurizes the brake pedal 33b to perform the deceleration operation, as shown in FIG. 23, the center moving device 43 of the cockpit unit 30 is operated to move forwardly the position of the cockpit unit 30 and the multi-stage rod 5 of the centrifugal force providing unit 1 is contracted so that the user feels more strongly the sense of deceleration.

Referring to FIG. 23f, in the case where the cockpit unit 30 is located at the specific position "A" of FIG. 22c, the user's position is rotated by 180 degrees by rotating the horizontal rotation gear 11 of the horizontal rotation unit 10 so that the centrifugal force acts against the user to maximize the sense of deceleration.

At the time of stopping (operating brake), the cockpit unit is restored by rotating the horizontal rotation gear 11 of the horizontal rotation unit 10 by 180 degrees more and the centrifugal force is eliminated by stopping the rotation of the centrifugal force providing unit. Further, at the time of the brake operation for only deceleration, the sense of stopping may be provided to the user by pulling forward the seat and by rotating the seat by 180 degrees when the position is beyond a certain position so as to provide the user with reversed centrifugal force.

As described above, the user is guided to stop the brake operation by the acceleration guiding operation (the operation of tilting the cockpit unit) by the pitching motor 15 in stopping state. When the user stops the brake operation, the cockpit unit is rotated again by 180 degrees to be restored.

In other words, the deceleration and acceleration operations are respectively guided by stimulating the user's equilibrium state in front and rear direction according to the rotation direction of the pitching motor 15. The pitching motor 15 is driven by receiving an operation signal stored in the program image. If the user does not perform the deceleration operation, the user's body becomes in unbalance state by guiding operation of the pitching motor 15 and accordingly the screen becomes out of focus or dark caused by digital effect of the image. Here, a mis-operation or over-operation or no-operation is determined by whether the position of the cockpit unit coincides with the equilibrium position required by the program or not. That is, the position signal of the cockpit unit sensed by the position sensor 28 is transferred to the centrifugal force providing unit and the base. The rotation number of the centrifugal force providing unit

and the length of the multi-stage rod are controlled according to the signal so that the user feels the sense of acceleration change corresponding to the manipulated amount.

Here, the brake operation is the same as above.

The present invention also provides a simulation effect for a gear transmission. In the conventional simulation apparatus, an optical illusion for sense of speed is provided by increasing only an image processing speed at the time of gear shift to high speed. However, because the optical illusion does not provide bodily sensed speed change, the effect is insignificant. In the gear transmission of actual driving, the ratio of an engine rpm to the rotation number of wheel is efficiently controlled for an effective use of engine power, and such effect can be bodily sensed by decreasing or increasing a resistance force against the inertia operation. That is, when the user misses the gear transmission timing or omits it, the user can sense the necessity for gear transmission by providing unbalance state like as excessive engine sound or sensing bodily the limit of more acceleration. FIG. 231 shows an operating state of the simulation apparatus according to the gear operation. Referring to FIG. 231, one example of acting direction of inertia G, the state of the screen basket and the position of the cockpit unit in the state at the time of gear transmission is shown. In this time, the user can feel stressful in low speed gear by providing balance state in case of 3 shift-gear driving and providing unbalance state in case of 1 or 2 shift-gear driving. The unbalance state is provided by the pitching motor. The simulation apparatus may provide a backward driving simulation.

FIG. 24 shows a simulation effect for backward driving by the simulation apparatus according to the one exemplary embodiment of the present invention.

Referring to FIG. 24, when the backward driving is performed by the simulation apparatus, the user is guided toward the direction of centrifugal force by rotating the horizontal rotation gear 11, and the image projector 41 is rotated by 180 degrees about the cockpit 31 to project an image inside the screen basket 22 in rear direction to the user.

Accordingly, the user can perform the backward driving training by turning his/her neck to watch the image projected in rear direction with feeling the centrifugal force acting forward. Also in the backward driving, the effects such as the eyesight guiding, the acceleration guiding, the rotation guiding, the assist mode, and the like, as shown in FIGS. 10 to 23, are provided.

The simulation apparatus of the present invention has been explained for the simulation apparatus of driving the automobile as an example, but not limited thereto. The simulation apparatus may be variously applied to the simulation of reports devices such as a water ski, a ski, and a snow board, the simulation of the playing apparatus such as roller coaster, and the simulation for testing driving apparatus such as motorcycle, the simulation of airplane, ship, and a game machine.

FIG. 25 shows various modifications of the present invention. Referring to FIG. 25a, in the case where the simulation apparatus is applied to the simulation of reports devices such as the motorcycle, the water ski and the ski, a cross sensor 60 as the steering device may be added to the cockpit unit.

Referring to FIG. 25b, in the case where the simulation apparatus is applied to the simulation of playing apparatus such as the roller coaster or the airplane, a plurality of image projector may be used for providing 3D image or circle- vision. However, in case of roller coaster, the steering device and the acceleration device may not be included.

Next, referring to FIG. 25c, in the case where the simulation apparatus is applied

for education or test, a cockpit unit as a lecturer's seat and a balance data outputting device for test may be further included. According to the present invention, the driving operation is performed considering centrifugal force and conversion of acting direction at real time. Continuous senses of acceleration, gravity and inertia are provided by gyro effect (continuous rotation of the centrifugal force providing unit, rolling and horizontal rotation of the rolling unit) so as to guide the continuous operation of the user to maintain the equilibrium state.

According to the present invention, the programmed operation is guided by providing a motive for the center movement by breaking the balance state of the user in equilibrium state. However, because the user's operation is performed in advance by prediction according to visual stimulus on the screen before the stimulation of the equilibrium state, only when the mechanical simulation guiding operation for stimulating the equilibrium state is synchronized with the center movement caused by the prediction operation, the user feels a sense of unity about the simulation operation, thereby allowing the reality to be prominently improved. It should be understood by those of ordinary skill in the art that various replacements, modifications and changes in the form and details may be made therein without departing from the spirit and scope of the present invention as defined by the
