Description

[0001] A DRIVING SIMULATOR FOR VEHICLES [0002]

Embodiments of the present invention relate to a vehicle driving simulator that provides the same operational feeling as the actual one.

In general, a vehicle driving simulator provides a simulation situation such as driving a car, thereby enabling a safe driving training and a game.

Examples of the conventional vehicle driving simulation device include a game machine installed in an electronic game room or a simulation device installed in an indoor driving school.

In this way, the conventional vehicle driving simulation apparatus displays a virtual situation rather than a real situation, so that a driver can feel thrill or remove a danger factor on an actual road so that a safe driving function can be practiced.

Although the structure is made to simulate the shape of the driver's seat of a real car, there are many limitations in reproducing its size, function and sensation.

In addition, in order to enjoy a simulation game of driving a car at home, it is necessary to purchase a game pack connected to a television and enjoy a car driving simulation game in the form of a ROM or CD media, but the adjustment method of the car is a joystick or a key input , It is different from the actual driving, so there is no real feeling. In view of this, a steering-wheel type joystick has been released, but it is not enough to give a feeling like a real car.

Also, in the case of driving education, the above-described structure can not achieve the purpose. For example, in the case of a vehicle which requires manual operation of the gear, the gear shift is performed according to the timing when the user releases the clutch and depresses the accelerator pedal.

Therefore, an apparatus for a simulator capable of being trained to operate a manual gear by providing an actual operation feeling can be considered.

An object of the present invention is to provide a vehicle driving simulator having a more improved structure and providing the same operational feeling as the actual one.

According to another aspect of the present invention, there is provided a vehicle driving simulator including a first sensor unit for sensing an input signal value of a clutch mounted on a simulator, When the gear is shifted in the second sensor unit and the half-clutch state and the input value of the accelerator pedal mounted on the simulator is received, the input value is compared with the input signal value, And a controller for outputting the voice signal through a speaker unit and a vibration pad mounted on the simulator.

According to one embodiment of the present invention, the speaker is implemented in a 5.1 channel so that sound is radiated in all directions with reference to the driver's seat mounted on the simulator, and the vibration pad is positioned on the upper portion of the clutch and the accelerator pedal As shown in Fig.

According to one example related to the present invention, the gear is operated through a gear assembly mounted on the simulator, and the gear assembly includes a center bar moving in association with the operation of the gear bar so that a user's gear- A first sensor unit configured to face a first portion to be sensed protruded to a side of the center bar to sense reciprocating movement of the center rod and a second sensor unit configured to face the center rod to detect a rotational movement of the rotator, Wherein the control unit generates an operation signal corresponding to the sensing of the sensor units and transmits the generated operation signal to the simulator, the rotator is formed to penetrate through the center rod, and the user To interfere with the lateral movement of the center rod And the second sensor unit may include the first sensor unit and the second sensor unit. The second sensor unit may include a plurality of interference fingers corresponding to the outer periphery of the center rod.

The vehicle driving simulator according to at least one embodiment of the present invention configured as described above can provide the same operational feeling as operating the actual gear to the user and shifting the gear by operating the clutch and the accelerator pedal.

Further, when the shape of the main body, the position of the driver's seat, and various kinds of operation devices are changed, the present invention can be applied to simulators of various types of vehicles.

Hereinafter, a vehicle driving simulator according to the present invention will be described in detail with reference to the drawings. The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

FIG. 1 is a conceptual diagram of a vehicle driving simulator according to an embodiment of the present invention, and FIG. 2 is a configuration diagram of a vehicle driving simulator according to an embodiment of the present invention.

The vehicle driving simulator 100 is formed similar to an actual vehicle. 1, a driver's seat is disposed at the center of the main body 201, and a steering wheel 230 and a monitor 202 are disposed in front of the driver's seat. The vibration pad 220 may be formed at the lower portion of the driver's seat. Thus, the driving sound and vibration of the engine can be provided to the user. The vehicle traveling environment is output to the monitor 202. The driving environment continuously changed in accordance with the operation of the vehicle user is output to the monitor 202. [

A clutch pedal 211, a brake pedal 213, an accelerator pedal 212, a gear rod 110, and a gear assembly 101 are disposed below the steering wheel 230, respectively. The clutch pedal 211, the brake pedal 213 and the accelerator pedal 212 are formed on the support plate 210 and the vibration pad 220 is formed on the lower side of the support plate 210. At one side of the support plate 210, a gear rod 110 and a gear assembly are disposed.

A plurality of speaker units 203 are arranged around the driver's seat. The speaker units 203 may be implemented as a 5. 1 channel so that sound is emitted in all directions with respect to the driver's seat.

The actual operating environment can be provided through the speaker unit 203 and the vibration pad 220 arranged as described above. That is, when there is an operation by the user, the same vibration and sound as actually operated are output through the speaker unit 203 and the vibration pad 220. For example, after actually recording a sound in a state in which the vehicle is operated, the recorded sound is output through the MP3 player, the output sound is amplified through the vibration amplifier 260, As shown in FIG.

1 and 2, the vehicle driving simulator 100 includes a first sensor unit 251, a second sensor unit 252, and a control unit 250 so that the operation of the user is detected by the simulator and operated accordingly .

The first sensor unit 251 is configured to sense the input signal value of the clutch mounted on the simulator and the second sensor unit 252 is configured to sense the gear mounted on the simulator. The second sensor unit 252 includes first and second sensor units 141 and 142 and second sensor units 143 and 144, which will be described later with reference to FIGS.

Also, the third sensor unit 253 is configured to sense the input value of the accelerator pedal 212 by the user.

Sound corresponding to each operation state is stored in the sound source unit 270 in the form of a file. Any one of the files stored in the sound source unit 270 is output through the speaker unit 203 and the vibration pad 220 by the signal of the control unit 250. [

The amplifier section 260 is formed to amplify sound toward the vibration pad 220.

The communication unit 251 converts the electrical signals and transmits the electrical signals so that the sensor units and the devices communicate with each other. The communication unit 251 is also connected to an external device by wire or wirelessly.

The interface unit 252 receives data from an external device, supplies power to each component in the simulator, or transmits data in the simulator to an external device. For example, a port for connecting a device equipped with a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, An audio I / O port, a video I / O port, an earphone port, and the like may be included in the interface unit 252.

When the gear is shifted in the half-clutch state and the input value of the accelerator pedal is received, the control unit 250 compares the input value with the input signal value, and sets the sound source set according to the difference to the speaker unit 203 And output through the pad 220. That is, the control unit is configured to output different sound sources according to the difference between the input value and the input signal value.

For example, when the gear is changed in the half-clutch state and the timing at which the accelerator pedal is depressed after the clutch pedal 211 is released is different from a predetermined time, the starting of the vehicle is turned off. Accordingly, in this case, sound and vibration corresponding to the start-off are output through the speaker unit 203 and the vibration pad 220. That is, when the time when the accelerator pedal is depressed is not made within a predetermined time after the clutch pedal 211 is released, it is determined that the gear change is failed, and the following operation is performed through the simulator. For example, after a predetermined vibration is transmitted to the user through the vibration pad 220, the vibration suddenly stops, and the sound related to the vibration is outputted through the speaker unit 203. [

In contrast, when the gear is changed and the accelerator pedal is depressed within a predetermined time in the half-clutch state, it is determined that the gear change has been successfully performed and the corresponding sound and vibration are transmitted to the speaker 203 and the vibration pad 220 ). For example, a sound of a soft engine can be output through the speaker unit 203 and the vibration pad 220. [

By knowing the process through the simulator by the user, the user can obtain the experience of actually driving the vehicle.

Fig. 3 is a perspective view of the gear assembly for a simulator shown in Fig. 1, Fig. 4 is a state diagram of the gear assembly for a simulator shown in Fig. 3, Fig. 6 is a view showing the state of use of the gear assembly for a simulator shown in Fig. 3, in which four gears are shown. Fig.

3, the gear assembly includes a gear rod 110, a center rod 133, a rotator 150, first sensor units 141 and 142, second sensor units 143 and 144, and a controller 250 .

The gear bar 110 is formed so as to give the user the same or similar operational feeling as that of actually operating the gear. The gear bar 110 is detachably coupled to the gear bar bushing housing 112. That is, smaller gear rods 110 may be used when used for small cars, and larger gear rods 110 may be used when used for large trucks.

The gear rod 110 is engaged with the gear shaft guide shaft 110 and its movement is restricted by the pitching limit pin 121. [ Accordingly, the movement of the gear rod 110 can be transmitted to the center rod 133 and the rotator 150.

The center rod 133 is formed to move in the left-right direction in accordance with the left-right movement of the gear rod 110. The center rod 133 is joined to the front center rod 131 by a ball joint 132. One end of the center rod 133 is engaged with the ball joint 132 and the other end is brought into contact with the stopper 171. The movement of the center rod 133 is restricted by the fixed block 161 and guided by the fixed block 161 to reciprocate.

The rotator 150 is formed so as to rotate counterclockwise or counterclockwise in accordance with the forward and backward movement of the gear bar 110. The rotator 150 is connected to the side bar 153 and the side bar 153 is connected to the gear bar 110. Ball joints 154 and 156 are formed on one side and the other side of the side bar 153. The front ball joint 154 is connected to the lower end of the gear bar 110 and the rear ball joint 156 is connected to the side bar 153 And the rotator 150 to each other. As a result, when the gear rod 110 reciprocates in the forward and backward directions, the rotator 150 rotates.

The rotator 150 has a through hole so that the center rod 133 passes through the through hole. A plurality of interference fingers 155 are formed on the inner circumference of the through hole. The interference chin 155 is formed to correspond to the outer periphery of the center rod 133 so as to interfere with the lateral movement of the center rod 133 to transmit a sense of operation to the user.

The forward and backward movement of the gear rod 110 is interfered by the interference chin 155 and the left and right movement of the gear rod 110 is interfered by the stopper 171 described later.

The first sensor units 141 and 142 are disposed to face the first sensing unit 138 protruding from one side of the center rod 133. [ The first sensor units 141 and 142 are formed in plural. That is, the first sensor units 141 and 142 include a first proximity sensor 141 for sensing the right movement of the first sensing unit 138 and a second proximity sensor 141 for sensing the left movement of the first sensing unit 138. [ And a proximity sensor 142. The first proximity sensor 141 and the second proximity sensor 142 are disposed apart from each other. The first proximity sensor 141 senses the movement of the center rod 133 to the right and the second proximity sensor 142 senses the movement of the center rod 133 to the left. A state in which neither the first proximity sensor 141 nor the second proximity sensor 142 is sensed is a neutral state in which the gear is neutral.

The second sensor units 143 and 144 are arranged to sense the rotation of the rotator 150. [ The second sensor units 143 and 144 are disposed to face the second sensing unit 151 protruding from the side surface of the rotator 150. [

The plurality of second sensor units 143 and 144 are formed. The second sensor units 143 and 144 are disposed apart from each other on the outer periphery of the rotator 150. The second sensor units 143 and 144 may include a third proximity sensor 143 sensing the left rotation of the second sensing unit 151 and a fourth proximity sensor 143 sensing the right rotation of the second sensing unit 151. [ And a proximity sensor 144. The state in which the first proximity sensor 141 and the second proximity sensor 142 are not sensed is a state in which the gear is in the neutral state or the state in which the gear is in the third state or the fourth state.

The control unit 250 generates an operation signal corresponding to the detection of the sensor units and transmits the generated operation signal to the simulator. The controller 250 may be formed on a circuit board or in the form of a chip such as a microprocessor.

The gear bar 110, the center rod 133, the rotator 150, the first sensor portions 141 and 142 and the second sensor portions 143 and 144 are formed on the plate 101. In particular, the center rod 133 and the rotator 150 are movably fixed to the plate 101.

The stopper 171 is accommodated inside the housing 172 formed on the plate 101. [ The stopper 171 is slidably movable within the housing 172. The stopper 171 is resiliently supported and interferes with the movement of the center rod 133 when the gear rod 110 moves left and right, thereby providing a user with a sense of operation. The movement direction of the center rod 133 is a first direction in which the stopper 171 reciprocates in accordance with the lateral movement of the gear bar 110, and the movement direction of the stopper 171 is a second direction perpendicular to the first direction. A stopping protrusion 139 is formed on one side of the center rod 133 and the stopper 171 elastically contacts the center rod 133. The movement of the center rod 133 is restricted by the stopper 139 and the stopper 171 when the center rod 133 is moved. When the center rod 133 is moved by a force exceeding a predetermined level, Thereby giving a sense of operation.

Further, the gear assembly for a simulator includes a clutch. The clutch is formed in the form of a normal pedal on the floor of the simulator tuning seat. The clutch is formed to lock or unlock the center rod 133. The clutch is connected to the connection pin 181, which is in contact with the stopper 171, by a wire. The connection pin 181 contacts the stopper 171 and is formed to reciprocate along the first direction. The movement of the stopper 171 is locked (restricted) or unlocked (unlocked) in accordance with the reciprocating motion of the connection pin 181. The connecting pin 181 is guided by the connecting pin housing 180.

Referring to FIG. 4, in the neutral state of the gear, the first to-be-sensed portion 138 formed on the center rod 133 is disposed between the first proximity sensor 141 and the second proximity sensor 142. In this case, the values detected by the first proximity sensor 141 and the second proximity sensor 142 are null. The second sensing unit 151 formed on the rotator 150 is disposed between the third proximity sensor 143 and the fourth proximity sensors 144 and 144. In this case, the values detected by the third proximity sensor 143 and the fourth proximity sensor 144 are null. One end of the stopper 171 is in contact with the center rod 133 between the engagement protrusions 139 formed on the center rod 133. This limits the lateral movement of the center rod 133. The other side of the stopper 171 is locked by the connecting pin 181. That is, the connection pin 181 restricts the stopper 171 from moving downward. When the user operates the clutch, the connection pin 181 moves in the lateral direction and the stopper 171 can move downward. Since the value detected by each proximity sensor through the controller 250 is null, the simulator can confirm that the gear is neutral.

5 and 6 show a state in which the gear is changed by the user's operation. When the user steps on the clutch and operates the gear rod 110, the gear may be in a single-stage state as shown in FIG.

And the first to-be-sensed portion 138 is arranged to face the second proximity sensor 142 when the gear is in the first stage. The second to-be-sensed portion 151 formed on the rotator 150 is arranged to face the third proximity sensor 143. The second proximity sensor 142 and the third proximity sensor 143 transmit the sensed value to the control unit 250, and the control unit 250 generates the corresponding signal. That is, the simulator recognizes that the gear is changed to the first gear.

In addition, when the user steps on the clutch and operates the gear 110, the gear can be in a state of six stages as shown in Fig.

And the first to-be-sensed portion 138 is arranged to face the first proximity sensor 141 in a state where the gear is six-tiered. The second to-be-sensed portion 151 formed on the rotator 150 is arranged to face the fourth proximity sensor 144. The first proximity sensor 141 and the fourth proximity sensor 144 transmit the sensed value to the control unit 250, and the control unit 250 generates the corresponding signal. That is, the simulator recognizes that the gear is changed to the first gear.

The above-described vehicle driving simulator is not limited to the configuration and method of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments may be selectively combined .
