BACKGROUND OF THE INVENTION
The present invention, in the running simulation apparatus performs simulation vehicle body attitude control in response to an occupant of the driving operation, regarding obstacles set TeiSo location for setting the obstacle to be displayed on the monitor.
[0002]
[Prior art]
Conventionally, a traveling simulation apparatus that operates a simulated vehicle body by a passenger's simulation operation has been adopted. In general, this type of traveling simulation apparatus is used, for example, for teaching two-wheeled vehicles and four-wheeled vehicles . This is to provide guidance so that sufficient risk prediction and risk prediction can be made when driving a real vehicle by causing the travel simulation device to experience an accident pattern (failure pattern) that is a concern during actual vehicle travel.
[0003]
However, in the simulation software used for learning, the driving environment of the simulated vehicle body is set in advance, and the accident pattern that occurs in this driving environment is always the same place. For this reason, it has been pointed out that once the above learning is experienced or the other's learning is seen, the accident pattern is recognized and the effectiveness of the learning cannot be obtained so much.
[0004]
Therefore, the present applicant made a selection for each parameter, storage means for storing a series of driving environments related to the simulated vehicle body displayed on the monitor into a plurality of parameters, and storing each type individually for each parameter. A driving simulation editing apparatus for a traveling simulation apparatus having an editing means for reading a kind of data from a storage means and assembling a series of driving environments has been proposed (JP-A-8-254945). Thereby, it is possible to edit a large number of driving environments and to freely edit the editing contents of the driving environments.
[0005]
[Problems to be solved by the invention]
However, in driving lessons, basic requirements to be learned are determined, and easy changes in the driving environment are restricted. In addition, the above-described conventional technology has a problem that, even if the driving environment can be freely assembled, creation of training software requires expertise and a lot of time.
[0006]
The present invention has been made to solve this kind of problem, a simple process and configuration, provides an obstacle setting TeiSo location of the setting operation of the obstacle easily and in a short time can be accomplished travel simulation device The purpose is to do.
[0007]
[Means for Solving the Problems]
In the obstacle setting device of the traveling simulation apparatus according to the present invention, a scenario data storage unit that stores scenario data related to the driving environment of the simulated vehicle body, and the presence / absence of an obstacle included in the obstacle pattern in the scenario data is changed. And an obstacle setting unit capable of setting and changing the position of the obstacle at an arbitrary position within the arrangement range designated by the obstacle pattern, and based on the information on the set obstacle, the scenario data A video creation unit for creating a video; and a terminal for setting and changing the presence / absence of the obstacle and the position of the obstacle, and the obstacle setting unit selects presence / absence of the obstacle on a screen of the terminal And a position control means for displacing the position of the obstacle on the road of the image showing the obstacle pattern .
[0008]
Thereby, the presence / absence of an obstacle and the setting of the position can be arbitrarily changed within a desired obstacle pattern, and variations can be easily increased even with one scenario data. Therefore, the obstacle setting operation can be performed easily and in a short time with a simple process and configuration, and versatility can be improved.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic perspective view of a two-wheeled vehicle riding simulation apparatus (travel simulation apparatus) 10 for implementing an obstacle setting apparatus according to an embodiment of the present invention. FIG. 2 is an outline of the riding simulation apparatus 10. It is a side view.
[0010]
The riding simulation apparatus 10 includes a simulated vehicle body 14 in which the occupant 12 performs a driving operation, a monitor 16 that displays a driving environment of the simulated vehicle body 14 as an image, and an operator (for example, an instructor) 18 that performs various input operations (obstacles described later). And a terminal 20 such as a computer that performs a setting operation).
[0011]
The simulated vehicle body 14 has two axes, a roll shaft 24 extending in the vehicle length direction (arrow A direction) on the base 22 and a pitch shaft 26 extending in the vehicle width direction (arrow B direction). The main frame 28 is supported with a degree of freedom of rotation. A seat 30 and a step 32 for seating the occupant 12 are provided at the rear of the main frame 28 in the vehicle length direction, and a steering shaft 34 is rotatably supported at the front of the main frame 28 in the vehicle length direction. The
[0012]
A handle 36 is attached to the upper end of the steering shaft 34, and a steering motor 38 is connected to the lower end of the steering shaft 34. The steering wheel 36 is configured to be given an operation load according to the driving state via a steering motor 38.
[0013]
The simulated vehicle body 14 is provided with a pair of left and right linear actuators 40, 40 symmetrically with respect to a plane that includes the axis of the roll shaft 24 and is orthogonal to the pitch axis 26, at a position offset in the axial direction of the roll shaft 24. . Each linear motion actuator 40 includes a hollow actuator main body 42 that can advance and retreat in the direction of arrow C along the ball screw 41 under the action of a servo motor, and the actuator main body 42 is connected to the main through a universal joint 44. It is connected to the frame 28.
[0014]
The steering wheel 36 incorporates various sensors for detecting the amount of accelerator operation performed by the occupant 12 and the operating force of the front brake, and the seat 30 is provided with sensors for detecting the moving direction and moving amount of the occupant 12. Further, in the vicinity of the step 32, a sensor for detecting the operation force of the rear brake and the shift change operation is provided.
[0015]
The detection signals from these various sensors are processed by an arithmetic processing unit 60 as shown in FIG. 3, and the pair of linear motion actuators 40 and the steering motor 38 are driven and controlled via the arithmetic processing unit 60. Thus, the posture of the simulated vehicle body 14 is controlled.
[0016]
The arithmetic processing device 60 includes a video creation unit 64 to which scenario data related to the driving environment is input from a training scenario database 62 that is a scenario data storage unit. The video creation unit 64 is connected to a random number generation unit 66 for controlling movements of other vehicles and pedestrians based on random numbers, and stores video data of urban landscapes, other vehicles and pedestrians, and the like. The video database 68 to be connected is connected.
[0017]
The video creation unit 64 calls the video data of the urban landscape and other vehicles and pedestrians from the video database 68, converts this video data into a video viewed from the occupant 12, and synthesizes it into a format for display on the monitor 16. After that, the video is output to the video controller 70. A video correction signal corresponding to the posture of the simulated vehicle body 14 is input from the motion calculation unit 72 to the video control unit 70. For example, although the simulated vehicle body 14 is tilted at the time of cornering, since no centrifugal force is generated in the simulated vehicle body 14, the image is tilted in the opposite direction to the simulated vehicle body 14 to cause the occupant 12 to feel that the simulated vehicle body 14 is largely inclined. Because.
[0018]
When the simulated vehicle body 14 travels on a frozen portion or floating sand portion, the posture of the simulated vehicle body 14 needs to be unstable or the braking distance must be increased. A posture correction signal is output from the video creation unit 64 to the posture control unit 74.
[0019]
The arithmetic processing device 60 has a function as an obstacle setting device according to the present embodiment, and sets the presence / absence of an obstacle included in the obstacle pattern in the scenario data read from the training scenario database 62. , An obstacle setting unit 76 capable of setting the position of the obstacle at an arbitrary position within the arrangement range designated by the obstacle pattern is provided.
[0020]
The operation of the riding simulation apparatus 10 configured as described above will be described below.
[0021]
In the linear actuator 40, when the pair of actuator main body portions 42 are raised or lowered at the same time, the simulated vehicle body 14 is given a forward or downward rotation with the pitch shaft 26 as a fulcrum, that is, a pitch operation. On the other hand, when the actuator main bodies 42 of the two linear actuators 40 are moved in the opposite directions, the simulated vehicle body 14 is given a lateral rotation around the roll shaft 24, that is, a roll operation.
[0022]
Therefore, the occupant 12 performs a driving operation of the simulated vehicle body 14 based on the driving environment displayed on the monitor 16. In the arithmetic processing unit 60, scenario data stored in the training scenario database 62 is read into the video creation unit 64, and the video creation unit 64 receives random movements of other vehicles and pedestrians from the random number generation unit 66. A random number is input to control based on
[0023]
Further, the video creation unit 64 is loaded with video data of urban landscapes, other vehicles, pedestrians, and the like from the video database 68, and this video data is converted into a video viewed by the occupant 12 and is sent to the video control unit 70. Is output. In the video control unit 70, the video correction signal is input from the operation calculation unit 72, the image signal corrected by the video correction signal is output to the monitor 16, and the driving environment is displayed on the monitor 16 as a video.
[0024]
Various failure patterns are specified in the scenario data regarding the driving environment displayed on the monitor 16. For example, in the terminal screen 78 shown in FIG. 4, in the driving environment on the highway, the confluence K1 of other vehicles, the passing K2, the fallen object K3 on the road surface, the deceleration K4 at the exit curve, the entrance K5 to the gate, the gate exit Failure patterns such as passing K6, merging K7 to the main line, response K8 in a traffic jam, avoidance K9 of a broken vehicle, and overtaking K10 of a truck are set.
[0025]
For example, in response to K8 during traffic jams, as shown in FIG. 5, a traffic jam video 80 is displayed on the monitor 16, and while fog is generated on the highway 81, the hazard 82 is turned on and the vehicle stops. A scene in which a track (obstacle) 84 is blocking the road is displayed. In the traffic jam image 80, a left rear view 86L and a right rear view 86R are displayed.
[0026]
Next, the operation of the obstacle setting device according to the embodiment of the present invention will be described below using the response K8 during a traffic jam.
[0027]
The operator 18 operates the computer which is the terminal 20, and operates the mouse 90 (see FIG. 1) so that the cursor 88 is overlaid on the corresponding K8 on the terminal screen 78 shown in FIG. Then, by clicking the mouse 90 at this position, the failure pattern is designated as the corresponding K8 in the traffic jam (step S1 in FIG. 6).
[0028]
Therefore, an obstacle pattern image 92 and an obstacle setting image 94 are displayed on the terminal screen 78 as shown in FIG. In the obstacle pattern image 92, the truck 84 that is an obstacle can be arbitrarily set on the highway 81 between the position P1 and the position P2. For example, the distance between the positions P1 and P2 corresponds to a distance traveled at 80 km for about 20 seconds.
[0029]
Therefore, first, the operator 18 operates the mouse 90 to set either the obstacle presence display 98 or the obstacle absence display 100 in the obstacle setting image 94 (step S2). When the obstacle presence display 98 is set (YES in step S3), the obstacle track 84 is set by operating the position control 102 at an arbitrary position between the positions P1 and P2 (step S3). S4). Thereby, the obstacle setting work in the corresponding K8 in the traffic jam is completed. Then, the process proceeds to step S5, where other failure patterns are designated as necessary, and the operation of changing the failure pattern in the scenario data by the operator 18 is completed.
[0030]
As shown in FIG. 3, an input signal from the terminal 20 is sent to an obstacle setting unit 76, where information related to the presence or absence and position of the obstacle is set and converted into actual video coordinates. And sent to the video creation unit 64. The video creation unit 64 changes the presence and / or position of an obstacle such as the track 84 in the scenario data, and displays the changed video on the monitor 16 from the video control unit 70.
[0031]
As described above, in the present embodiment, the obstacle pattern included in the scenario data regarding the driving environment of the simulated vehicle body 14 is designated, and the presence or absence of the obstacle (such as the truck 84) included in the designated obstacle pattern is set. If necessary, the position of the obstacle is set at an arbitrary position within the arrangement range specified in the obstacle pattern.
[0032]
For this reason, the presence / absence and position of an obstacle can be arbitrarily changed within a desired obstacle pattern, and the variation can be easily increased even with one scenario data.
[0033]
This eliminates the need for special skills and the time required to produce multiple types of training software in advance, and it is easy and short to set up obstacles with a simple process and configuration. This is advantageous in that it can be performed in time and the versatility can be improved.
[0034]
In the present embodiment, the motorcycle riding simulation apparatus 10 has been described. However, the present invention is not limited to this, and can be applied to, for example, a four-wheeled vehicle driving simulation apparatus.
[0035]
【The invention's effect】
Obstacle setting TeiSo location of the running simulation apparatus according to the present invention, with the configuration of the presence and position of the obstacle in the desired fault pattern is arbitrarily changed, even one scenario data, variations of Increase is achieved. Therefore, the obstacle setting operation can be performed easily and in a short time with a simple process and configuration, and versatility can be improved.
