Description

  The present invention relates to a vehicle simulation apparatus used for traffic safety education, games, physical fitness training, and the like.

  In order to simulate the driving of airplanes, automobiles, motorcycles, bicycles, etc., simulation apparatuses corresponding to each vehicle have been proposed, and some of them have been put into practical use. Among these, in the bicycle simulation device, the driver performs simulation driving by stroking the pedal while straddling the saddle of the simulation bicycle, and calculates the simulation speed etc. by detecting the rotation of the pedal with a predetermined speed sensor. Processing is done.

  In the vehicle simulation apparatus, it is preferable to display the traveling scenery that changes according to the simulated traveling speed in the forward direction so that the sense of reality is further improved. By the way, if the display device is provided not only in the front but also in the rear, it is preferable that a more realistic driving situation is realized. From such a viewpoint, a driving system has been proposed in which a large screen is arranged behind the driver and a rear background is projected by a projector (see, for example, Patent Document 1).

JP 2005-3923 A

  By the way, in the driving system described in Patent Document 1, the rear screen is large and heavy, and projects an image by a projector. Therefore, a large space is required, and installation in a narrow place is difficult. At the same time, it is not suitable for applications that frequently convey.

  Further, if a simulated vehicle or a driver is present between the projector and the rear screen, the projection light is shielded, and therefore it is necessary to carefully examine how to arrange the projector. When the projector cannot be arranged at an appropriate position facing the rear screen, the projected image is distorted.

  Further, whether or not to see the projected rear background depends on the driver's intention, and is not suitable for the purpose of reliably confirming the rear as safety education / training.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a vehicle simulation apparatus capable of displaying information with a small and simple configuration behind the driver.

  A vehicle simulation apparatus according to the present invention includes a simulated vehicle operated by a driver, a front display unit that displays a scene based on the operation of the simulated vehicle, and connected to the simulated vehicle and behind the boarding position of the driver. And a rear display portion provided. Thus, the vehicle simulation apparatus can be configured in a small and simple manner by adopting an integrated configuration in which the rear display unit is connected to the simulated vehicle.

  In this case, if the rear display unit is a monitor capable of displaying an image, it can display various practical images to improve the sense of reality.

  The rear display unit may be one or more lamps and controlled to be lit in a plurality of colors. Thereby, a back display part can be made into a still smaller and simple structure.

  Further, an input determination that is provided in the simulated vehicle and that is input by the driver, and that performs a predetermined comparison determination based on the signal input by the input device and the information displayed on the rear display unit. And an output unit indicating a result of the comparison determination may be provided. Thereby, a driver | operator can confirm the information shown by the back display part, and it is used suitably for uses, such as safety education and training.

  Further, the rear display unit is one or more lamps and is controlled to be lit in a plurality of colors, and the input device has a plurality of switches that indicate the colors to which the lamps are lit. Can be operated. Further, the configuration of the input device becomes simple and inexpensive.

  According to the vehicle simulation device of the present invention, the rear display unit is integrated with the simulation vehicle, so that the device is small and simple and can be installed in a narrow place. Moreover, since the rear display unit is integrated with the simulation vehicle, it is excellent in portability and can be suitably used for applications such as frequent transportation.

  Hereinafter, a bicycle simulation apparatus 10 that is an embodiment of a vehicle simulation apparatus according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, a bicycle simulation apparatus 10 according to the present embodiment includes a simulated bicycle (simulated vehicle) 12 and a monitor (front display unit) 14 that displays a scene corresponding to the driving of the simulated bicycle 12 on a screen 14a. A speaker 15 that gives simulated sounds and voice instructions to the driver, a mat switch 16 provided at a position where the driver gets on and off, a main control unit 18 that performs overall control of the bicycle simulation apparatus 10, and a simulated bicycle 12 and a lamp unit (rear display unit) provided behind the boarding position of the driver. The main control unit 18 is disposed in front of the simulated bicycle 12, and the monitor 14 and the speaker 15 are disposed above the main control unit 18 at a position where the driver of the simulated bicycle 12 has good visibility. The main control unit 18, the monitor 14, and the speaker 15 are supported by the four support columns 21 so as to be movable up and down, and the height can be adjusted according to the body shape of the driver. The main control unit 18 has a function of displaying an image corresponding to the simulation on the screen 14a, and also has a function as an image processing computer.

  Next, the simulated bicycle 12 will be described. In the following, the mechanisms provided on the simulated bicycle 12 one by one on the left and right will be described separately by attaching “L” to the number sign of the left one and “R” to the number sign of the right one.

  The simulated bicycle 12 fixedly supports the frame 20, a saddle 24 connected to the frame 20 via a seat pillar, a handle 28 that can rotate about the head tube 20a of the frame 20, and the head tube 20a. It has two front forks 30R and 30L as a stand, and a rear wheel 32 rotatably supported by a seat stay 20b and a chain stay 20c of the frame 20. A pipe 31 extending in the lateral direction is provided at the front ends of the front forks 30R and 30L, and the pipe 31 is grounded to the floor. The stem 28a of the handle 28 has a folding mechanism 28b in the vicinity of the head tube 20a, and can be folded or disassembled.

  The front forks 30R and 30L are similar in shape to the front fork of a bicycle (or motorcycle) in appearance, but do not rotate in conjunction with the handle 28 like an actual front fork. There are no front wheels. The rear wheel 32 is provided with a tire 32a having a slightly smaller diameter, and serves as a rear stand by the tire 32a being in contact with the floor. As described above, the simulated bicycle 12 is supported by the front forks 30R and 30L and the rear wheel 32 and stands up. A controller 46 is fixed between the front forks 30 </ b> R and 30 </ b> L and the pipe 31 via a bracket 33.

  The simulated bicycle 12 includes a rotation drive mechanism unit 40, a speed detection mechanism unit 42, a braking mechanism unit 44, a controller 46, and a steering angle sensor 50 (see FIG. 4) that detects the steering angle of the handle 28. A microphone 52 for inputting a driver's voice, an input device 53 for input by the driver, a reverse switch 54 provided at the rear portion of the saddle 24, and a rearview mirror extending from the vicinity of the right end of the handle 28 55. The reverse switch 54 is a switch operated when the driver gets off and performs a predetermined simulated reverse operation.

  The rotation drive mechanism 40 includes a pair of cranks 62L and 62R connected to the left and right of a crankshaft 60 provided in the crank tube 20e, pedals 64L and 64R provided at the tips of the cranks 62L and 62R, A front sprocket 66 provided on 62R, a rear sprocket 70 that is rotationally driven from the front sprocket 66 via a chain 68, and a one-way clutch (also referred to as a free hub) 72 that is rotationally driven from the rear sprocket 70. And an iron flywheel (rotary body) 74. The flywheel 74 is provided between the seat tube 20 f and the rear wheel 32, and is supported by a one-way clutch 72.

  The one-way clutch 72 transmits only the rotational driving force in the forward direction of the rear sprocket 70 to the flywheel 74 by an internal ratchet mechanism. Therefore, when the crankshaft 60 rotates in the reverse direction, or when the rotation of the crankshaft 60 stops while the flywheel 74 is rotating in the forward direction, the flywheel 74 is independent of the crankshaft 60. The rotation state at that time (rotation or stop in the positive direction) is maintained.

  As shown in FIGS. 2 and 3, the speed detection mechanism unit 42 includes a wheel rotation detection unit 76 and a crank rotation detection unit 78. The wheel rotation detection unit 76 includes a mounting bracket 80 provided between the seat stay 20b and the chain stay 20c on the right side, and a first speed pickup 82 provided on the mounting bracket 80. The first speed pickup 82 is disposed at a position close to and opposed to the three spokes 74a of the flywheel 74. When the flywheel 74 rotates, the first speed pickup 82 indicates whether or not the spoke 74a is present. Is supplied to the controller 46.

  The crank rotation detector 78 has a mounting bracket 84 fixed to the crank tube 20e, a second speed pickup 86 provided on the mounting bracket 84, and a detected rotor 88 fixed inside the front sprocket 66. . The rotor 88 to be detected is an arc-shaped plate of approximately 90 °, and is disposed at a position facing the second speed pickup 86 in the vicinity thereof. When the crankshaft 60 and the front sprocket 66 are rotated by pedaling the pedals 64L and 64R, the second speed pickup 86 supplies a signal indicating whether or not the detected rotor 88 is present to the controller 46. The second speed pickup 86 and the first speed pickup 82 are compatible.

  As shown in FIG. 4, the brake mechanism 44 is elastically rotatable with two brake levers 100L and 100R provided on the handle 28, and brake wires 102 and 104 connected to the brake levers 100L and 100R. Pulleys 106L and 106R, rotation sensors 108L and 108R, and a drum brake 110 (see FIG. 3) for braking the flywheel 74.

  The brake wire 104 is bifurcated by a branch mechanism 111 on the way, one brake wire 104a extends in the direction of the front forks 30R and 30L, and the other brake wire 104b is connected to the drum brake 110. Yes. At the branch portion of the brake wire 104, a part of the outer wire 112 is peeled off and the end thereof is supported by the ring 114, and the exposed inner wire 116 is connected to the two inner wires by pressure bonding, caulking, welding, or the like. Is the brake wire 104a and the other brake wire 104b. Therefore, by operating the brake lever 100R, the two brake wires 104a and 104b are pulled simultaneously.

  The brake wire 104a and the brake wire 102 cross on the way, and the lower ends are connected to the pulleys 106R and 106L. When the brake levers 100L and 100R are not pulled, the pulleys 106L and 106R are elastically biased by a spring (not shown) so that the convex portions 118L and 118R face upward. At this time, the brake levers 100L and 100R are elastically biased by the pulleys 106L and 106R and are separated from the handle 28.

  Pulling the brake levers 100L and 100R in the direction of the handle 28 causes the pulleys 106L and 106R to elastically rotate, and the convex portions 118L and 118R face downward. The pulleys 106L and 106R can rotate until the convex portions 118L and 118R come into contact with the stoppers 120L and 120R.

  The rotation angles of the pulleys 106L and 106R can be detected by the rotation sensors 108L and 108R, and the detected angle signals are supplied to the controller 46, respectively. The controller 46 supplies the main controller 18 with a signal corresponding to the detected rotation angle signals of the pulleys 106L and 106R, in other words, the amount of operation of the brake levers 100L and 100R.

  As shown in FIG. 3, the drum brake 110 is disposed concentrically with the flywheel 74, and the arm 110a is connected to the end of the brake wire 104b. The drum brake 110 rotates integrally with the internal drum body connected to the flywheel 74. When the brake wire 104b is pulled by operating the brake lever 100L, the arm 110a tilts, the internal brake shoe expands in the outer diameter direction, and contacts the drum body to generate a frictional force. The wheel 74 is braked.

  As shown in FIGS. 1 and 5, the lamp unit 19 is supported by two stays 130 fixed to the left and right seat stays 20b and the chain stay 20c, and is mounted on the saddle 24 obliquely behind the rear wheels 32. It is located at a position behind the driver and is visually recognized when the driver turns around or is visible at the rearview mirror 55. A reinforcing plate 130 a is provided between the two stays 130. The lower end of the stay 130 is fixed together with the hub of the rear wheel 32.

  On the front surface of the lamp unit 19, three round lamps 132, 134 and 136 are arranged side by side in order from the right, and emit light in red, yellow and blue in order. The lamps 132, 134 and 136 are individually controlled to be lighted from the main control unit 18 via the controller 46. The lamps 132, 134, and 136 need not be unnecessarily large because they only need to be visually recognized by the driver, and the lamp unit 19 as a whole can also be configured to be small and light. In FIGS. 5 and 6, red is shown with cross hatching, yellow with single hatching, and blue with no hatching.

  As shown in FIGS. 4 and 6, the steering angle sensor 50 is provided at the lower end portion of the head tube 20 a and detects the rotation angle of the stem 28 a that supports the handle 28. Since the microphone 52 is provided on the handle 28 and is close to the driver's face, the driver's voice is clearly input. The input device 53 is provided on the handle 28 at a position where the input operation is easy. Three round switches 138, 140 and 142 are arranged in the horizontal direction on the upper surface, and the red, yellow are sequentially arranged from the right. The color is blue. That is, the input device 53 has a shape substantially similar to that of the lamp unit 19, and the color arrangement of the switches 138, 140, and 142 is the same as that of the lamps 132, 134, and 136. A character string “rear confirmation” is printed on the upper surface of the input device 53. The switches 138, 140, and 142 need only be large enough to be pressed by a finger, and the input device 53 as a whole can be configured to be small, light, and inexpensive.

  The steering angle sensor 50, the microphone 52, the reverse switch 54, and the switches 138, 140, 142 are connected to the controller 46 and supply a steering angle signal, an audio signal, and a switch operation signal.

  Returning to FIG. 1, the mat switch 16 includes an independent left switch 150L and a right switch 150R, and is arranged at a position where the driver can step on the head tube 20a of the frame 20 with both feet when getting off the vehicle. Yes. That is, the left foot steps on the left switch 150L and the right foot steps on the right switch 150R. The left switch 150 </ b> L and the right switch 150 </ b> R are turned on by being stepped on, and supply the on signal to the controller 46.

  Each of the left switch 150L and the right switch 150R has a thin mat shape, and is arranged between a grid-like vertical electrode line and a horizontal electrode line that are attached to face the back rubber and the back rubber, and between the back rubber and the back rubber. With inserted soft insulation. The vertical electrode line and the horizontal electrode line are connected to one of two output terminals (not shown). The surface rubber elastically deforms while compressing the insulating material when the driver steps on the foot, and the vertical electrode line and the horizontal electrode line come into contact at the intersection. As a result, the two output terminals are conducted and turned on. If the foot is released, the vertical electrode line and the horizontal electrode line are separated and turned off. The mat switch 16 is not a left and right independent type, but a mat switch in which two switches are integrated may be used, for example, arranged on the left side of the simulated bicycle 12. With such a mat switch arrangement, after the driver gets off to the left, the user can step on the spot to realize a more realistic walking action by pushing in the walking mode, which will be described later.

  As shown in FIG. 7, the controller 46 includes an input interface unit 170, a CPU (Central Processing Unit) 172, and a first communication unit 174. The first communication unit 174 is connected to the second communication unit 192 of the main control unit 18 and performs real-time communication with the main control unit 18. The input interface unit 170 is connected to the steering angle sensor 50, the microphone 52, the first speed pickup 82, the second speed pickup 86, the rotation sensors 108L and 108R, the reverse switch 54, the left switch 150L, and the right switch 150R. Input signals and digital signals.

  The CPU 172 processes or converts the signals of the electrical components described above and transmits the signals to the main control unit 18 via the first communication unit 174. For example, the CPU 172 obtains the rotational speed N1 of the flywheel 74 and the rotational speed N2 of the crankshaft 60 from the frequencies of the signals supplied from the first speed pickup 82 and the second speed pickup 86, and a predetermined constant for the rotational speed N1. To obtain the simulated traveling speed V and supply it to the main control unit 18.

  The main control unit 18 includes a status setting unit 180 that sets the status of simulated driving, an arithmetic processing unit 182 that performs arithmetic processing according to the traveling status, a display control unit 184 that controls display of the monitor 14, and a speaker 15 An acoustic driver 186 that performs acoustic output, a warning unit 188 that performs a predetermined warning to the driver, a voice recognition unit 190 that recognizes voice input from the microphone 52, a rear confirmation processing unit 191, and the first It has the 2nd communication part 192 which performs communication control with the communication part 174, and the memory | storage part 194 which can read / write data. The rear confirmation processing unit 191 compares and determines the random number generation unit 191a, the rear display control unit 191b that controls the lighting of the lamp unit 19, and the signal input by the input device 53 and the information indicated by the lamp unit 19. An input determination unit 191c.

  In practice, the main control unit 18 includes a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), and a hard disk (HD) as a storage unit. 7 is realized by the CPU reading a program recorded on the HD and executing the program in cooperation with the ROM, RAM, and predetermined hardware.

  Next, a method for simulating bicycle travel using the bicycle simulation apparatus 10 configured as described above will be described.

  In step S1 of FIG. 8, it is confirmed whether or not the mat switch 16 is turned on. That is, when at least one of the left switch 150L or the right switch 150R of the mat switch 16 is turned on, the process proceeds to step S2, and when both are off, the process waits at step S1. In other words, when the driver stands on the mat switch 16, the process automatically proceeds to step S2. Until then, the driver stands by in step S1 and enters a predetermined power saving mode (for example, the monitor 14 is turned off). I can keep it.

  In step S2, a simulated operation is started and a predetermined start screen is displayed on the screen 14a. In this start screen, an image of a stopped bicycle and an image of a person who is a driver standing next to the bicycle are displayed. In addition, on the screen 14 a, the characters “Start simulated driving. Sit on the saddle and stroke the pedal.” Are displayed on the screen 14 a, or sound of similar words is emitted from the speaker 15.

  In this manner, the simulated operation can be automatically started by stepping on the mat switch 16, and the simulated operation can be started without a sense of incongruity without requiring a complicated operation. In addition, the driver only needs to perform an operation according to an instruction issued from the screen 14a or the speaker 15, and can perform an easy operation without a manual or the like, and even a child can perform a simulated driving.

  In step S3, it is confirmed whether or not the mat switch 16 is turned off. That is, when both the left switch 150L and the right switch 150R are turned off, the process proceeds to step S4, and when at least one is turned on, the process waits in step S3.

  In other words, when the driver steps over the saddle 24 and removes his / her foot from the mat switch 16, the process automatically proceeds to step S4, and actual driving in the simulated driving can be started. At this time, the start screen is terminated and an image of a bicycle and an image of a person riding on the bicycle are displayed.

  In step S4, it is confirmed whether or not a predetermined traveling condition is satisfied. When the travel condition is satisfied, the process proceeds to the travel mode of step S5, and when the travel condition is not satisfied, the process proceeds to step S6. The traveling mode is a mode for performing a simulated traveling by driving the pedals 64L and 64R while operating the steering wheel 28 while the driver is sitting on the saddle 24. In this case, a scene that changes based on the simulated traveling speed V and the steering angle obtained based on the first speed pickup 82 and the steering angle sensor 50 is displayed on the screen 14a (see FIG. 1). In the travel mode, a predetermined warning may be issued when the simulated travel speed V is equal to or higher than the specified speed, or when the virtual bicycle protrudes from the virtual road.

  In step S6, it is confirmed whether the simulated driving status is stopped, paused, or the signal is red. If the stop, pause, or signal is red, the process proceeds to the stepped mode of step S7. Otherwise, the process proceeds to step S8. In the foot landing mode, the driver operates the brake levers 100L and 100R to set the simulated traveling speed V to 0 and then gets off and steps on the mat switch 16. As a result, a scene in which the driver and the bicycle are stopped at a red signal is displayed on the screen 14a. The foot landing mode is canceled when the signal changes from red to blue in the simulated driving situation, or when the left and right safety checks are made securely. As described above, after the landing mode is canceled, the backward confirmation process is executed before the driver straddles the saddle. This backward confirmation process will be described later.

  In step S8, it is confirmed whether or not the state of the simulated driving is a case where the vehicle passes a pedestrian priority road such as a pedestrian crossing or a pedestrian exclusive road such as a sidewalk. When it passes through a pedestrian priority road or a pedestrian exclusive path, it moves to the walking mode of step S9, and it moves to step S10 in the case other than that. The walking mode is a mode for pushing a bicycle on a pedestrian path or the like, for example, a mode for learning pushing walking that does not cause trouble for other pedestrians. In this case, the driver gets off the vehicle and steps on the mat switch 16 to reproduce the walking state, and a corresponding scene is displayed on the screen 14 a of the monitor 14.

  In step S10, it is confirmed whether or not the simulated driving situation is a situation where the bicycle is moved backward. In the case of reverse, the process proceeds to the reverse mode in step S11, and in other cases, the process proceeds to step S12. The reverse mode is a mode in which the driver who gets off moves backward while pushing the bicycle. In this case, the driver gets off the vehicle and steps on the mat switch 16 while turning on the reverse switch 54 to reproduce the reverse state, and a corresponding scene is displayed on the screen 14 a of the monitor 14.

  In step S12, it is confirmed whether or not a predetermined end condition is satisfied. If the end condition is satisfied, the simulated operation is terminated. If the condition is not satisfied, the process returns to step S4 and the simulated operation is continued. Further, the process returns to step S4 even after the processes of steps S5, S7, S9 and S11 are completed.

  When the simulation operation is to be terminated, it is confirmed whether or not the mat switch 16 is turned on, as in step S1. In this case, when the mat switch 16 is turned on, it is possible to detect that the driver has got off the simulated bicycle 12, and based on this, the simulated driving is terminated, and a standby state such as a predetermined power saving mode is established. Return to. In step S2, if the simulated bicycle 12 is not operated at all during a predetermined period after the mat switch 16 is turned off, the driver once steps on the mat switch 16 but gets on the simulated bicycle 12. In this case, it is preferable to return to the standby state because it is considered that the user has left without any problems.

  Next, the backward confirmation process will be described with reference to FIG. The backward confirmation process is executed, for example, before starting the traveling mode, or after the landing mode is canceled and before the driver straddles the saddle. The timing for executing the backward confirmation mode is determined by the situation setting unit 180 and is mainly executed by the backward confirmation processing unit 191.

  First, in step S101, one random number R of 1, 2, or 3 is generated by the random number generator 191a. The obtained random number R is supplied to the rear display control unit 191b and the input determination unit 191c.

  In step S102, the rear display control unit 191b performs lighting control of the lamp unit 19 based on the random number R. That is, when the random number R is 1, the red lamp 132 is turned on. When the random number R is 2, the yellow lamp 134 is turned on, and when the random number R is 3, the blue lamp 136 is turned on. As a result, any one of the lamps 132, 134, and 136 is turned on, and information based on the random number R is indicated.

  In step S103, backward confirmation guidance is performed. That is, the characters “Please check backwards before boarding and press the corresponding switch” are displayed on the screen 14a, or the voice of the same word is emitted from the speaker 15 to prompt the switch operation of the input device 53. As a result, the driver is required to check the image displayed on the rearview mirror 55 or to look back and check the lighting status of the lamp unit 19, and any one of the lamps 132, 134, 136 is turned on. It is required to operate the switch of the same color among the switches 138, 140, and 142 on the input device 53 according to the color of the lamp that is being used. The process of step S103 may be omitted when advanced is performed, and the backward confirmation may be performed spontaneously.

  In step S104, a switch signal is input from the input device 53, and the obtained signal is an input value S. The input value S is 0 in the initial state, and S ← S + 1 when the red switch 138 is on, S ← S + 2 when the yellow switch 140 is on, and S ← when the blue switch 142 is on. S + 4. When the switches 138, 140, and 142 are individually turned on, the input value S is 1, 2, and 4, and when a plurality of switches are pressed simultaneously, the input value S is 3 or 5-7.

  In step S105, it is confirmed whether or not a switch signal has been input. If the input has been confirmed, the process proceeds to step S106. If the input has not been performed and a predetermined time has elapsed, the process proceeds to step S107. If it is before the predetermined time has elapsed, it waits until an input is made.

  In step S106, the input determination unit 191c compares and determines the input value S and the random number R. If S = R, it is determined that the correct switch operation has been performed, and the process proceeds to step S108. Otherwise, an erroneous operation is performed. It is determined that it has been made, and the process proceeds to step S107.

  In step S107, a predetermined attention is output. That is, the characters “Please operate the switch.” Or “The operation is wrong. Please try again from the backward confirmation.” Are displayed on the screen 14a, or the sound of the same word is emitted from the speaker 15, and step S101. Return to, and confirm the backward direction again.

  On the other hand, in step S108, a progress guidance output is performed. In other words, the characters “Safety confirmation in the rear has been correctly performed. Please start driving” are displayed on the screen 14a, or the sound of the same word is emitted from the speaker 15.

  In step S109, all the lamps 132, 134, and 136 are turned off under the action of the rear display control unit 191b. Thereafter, the process shown in FIG. 9 ends, and the process returns to the main routine (see FIG. 8).

  As described above, according to the bicycle simulation apparatus 10 according to the present embodiment, the bicycle simulation apparatus 10 is configured to be small and simple by providing the lamp unit 19 as an integral configuration connected to the simulation bicycle 12. It can also be installed in narrow places. Further, since the lamp unit 19 is integrated with the simulated bicycle 12, the lamp unit 19 is excellent in portability and can be suitably used for applications such as frequent transportation.

  The lamp unit 19 is controlled to be lit in three colors, and has a small size, light weight, and low cost with the lamps 132, 134, and 136 as main components. Since the lamps 132, 134, and 136 emit light selectively based on the random number R, the driver does not remember the light emission pattern, and the rearward confirmation can be surely performed.

  Furthermore, the bicycle simulation apparatus 10 includes the input device 53 and the input determination unit 191c that compares and determines the input value S and the random number R of the input result, thereby allowing the driver to input information indicated by the lamp unit 19. It can be used suitably for applications such as safety education and training.

  The input device 53 has a shape substantially similar to that of the lamp unit 19, and the color arrangement and shape (round shape) of the switches 138, 140 and 142 and the lamps 132, 134 and 136 are the same. Operation is possible, and children and the like can also operate easily.

  For educational safety confirmation, too few lamps of different colors provided in the lamp unit 19 are not suitable for training. On the other hand, too many lamps require excessive confirmation that is different from the actual safety confirmation operation. become. Therefore, the number of lamps provided in the lamp unit 19 is 2 to 10, more preferably 3 to 5.

  The lamps 132, 134 and 136 are set to have individual meanings. For example, the red lamp 132 is prohibited from traveling, the yellow lamp 134 is prohibited to travel, the blue lamp 136 is permitted to travel, and the red lamp 132 is permitted to travel. When traveling starts when the lamp 132 is lit (when the simulated traveling speed V ≠ 0), a predetermined caution may be output. In this case, the input device 53 may be omitted.

  The lamps 132, 134, and 136 are not limited to a round shape, and may be lit in the shape of a mark imitating a four-wheeled vehicle, a bicycle, a pedestrian, or the like. In this case, the input device 53 may be operated based on the meaning indicated by each mark. Furthermore, the lamp provided in the lamp unit 19 is not limited to a single color light emitting type, and a lamp that emits light by switching to about three colors with one lamp may be used. Furthermore, the display means is not limited to a light emitting type such as a lamp, but may be a switching shielding type of a color display plate.

  The means for inputting the result of the backward confirmation to the input determination unit 191c is not limited to the input device 53, and voice input may be performed using, for example, a microphone (input device) 52. The means for outputting the comparison judgment made by the input judgment unit 191c is not limited to the screen 14a or the speaker 15, and a dedicated warning buzzer or the like may be used. The stay 130 is not limited to a beam structure, and may be a deformable tube structure made of a spiral metal plate.

  In the above description, the lamp unit 19 has been described as an example of the rear display unit for confirming the rear, but a small and light monitor 200 as shown in FIG. 10 may be used. The monitor 200 is, for example, a liquid crystal display type, and is supported by the stay 130 in the same manner as the lamp unit 19. Various actual images (including moving images) corresponding to the simulated driving conditions are displayed on the monitor 200 under the action of the main control unit 18, and the sense of reality is improved.

  In this case, by displaying the image 202 of the vehicle, the driver confirms that the vehicle is approaching or moving away from the rear, and whether or not the input device 53 prompts a predetermined input operation to confirm correctly. It is good to compare and judge. Further, by displaying the image 204 imitating the lamp unit 19, the same processing as the backward confirmation processing of FIG. 9 can be performed. When the image displayed on the monitor 200 is changed based on the simulated traveling speed V, a more realistic simulation is realized.

  The monitor 200 does not require a separate mechanism such as a projector when displaying an image and can be easily installed, and the image is not distorted. Further, since there is no projector, the driver and the simulated bicycle 12 do not shield the image projection.

  The vehicle simulation apparatus according to the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention. For example, a simulation of a motorcycle or a four-wheeled vehicle is used. It can also be applied to a device.
