Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering load device capable of appropriately setting a load for steering used in a game device, a driving simulator, etc., a game device using the same, and a driving simulator.

[0002]

2. Description of the Related Art Conventionally, there is known an arcade game machine in which a player operates a steering wheel to play a game while watching a game screen displayed on a display. For example, a racing game type game device in which a player drives a racing car displayed on a display and competes for time and rank is well known.

In such an arcade game machine, a method of applying an appropriate load to the steering wheel is assumed on the assumption that the vehicle is actually traveling. For example, in the simplest case, a spring or the like is used to generate a reaction force on the steering shaft in proportion to the steering angle.

[0004]

By the way, in the above-mentioned conventional game machine, since the actual running of the vehicle is not accurately simulated, the steering operation feeling is different from the actual running of the vehicle. There was a problem of lacking reality. For example, when a spring is used to generate a reaction force, the reaction force is set regardless of the vehicle speed of the racing car, and therefore the steering operation feeling is considerably different from that when an actual vehicle is driven.

On the other hand, as a conventional technique to improve this point, there is known a "steering reaction force generating device for a driving simulator" disclosed in Japanese Patent Laid-Open No. 4-232829 proposed by the present applicant. By using this conventional technique, it is possible to realize a reality that is relatively close to actual traveling.

However, if the steering reaction force is set to be heavy so as to be suitable for high-speed running, the steering becomes unnecessarily heavy when low-speed running is mainly performed such as city running. On the other hand, if the steering reaction force is set lightly to suit low speed running beforehand, the steering becomes too light during high speed running,
There was a problem that the straight running stability of the vehicle could not be maintained. Therefore, a method has been desired in which the weight of the steering wheel can be freely set according to the traveling course.

The present invention was created in view of the above circumstances, and it is possible to obtain a realistic steering operation feeling close to the actual traveling state, and to freely set the steering load for each traveling course. An object of the present invention is to provide a steering load device that can be used, a game device using the same, and a driving simulator.

Based on the resistance force calculation means for calculating the resistance force against the angular velocity, the steering angle detected by the steering angle detection unit and the moving speed of the moving body, a restoring force for returning the steering wheel to a predetermined position is calculated. A restoring force calculating means for calculating and an adding means for adding the values calculated by the respective calculating means are provided, and the value of the load applied from the load device to the steering wheel is set based on the addition result by the adding means.

Further, the restoring force calculation by the restoring force calculation means is variably performed for each traveling course.

A game apparatus according to a fourth aspect of the present invention applies the steering load device according to any one of the first to third aspects to a drive game, and based on the moving speed of the moving body set by the game calculation means, It is characterized in that the load of the steering wheel is set by the load setting unit.

A driving simulator according to a fifth aspect of the present invention applies the steering load device according to any one of the first to third aspects to a driving simulator, and the load is calculated based on a moving speed of a vehicle set by a simulation calculation means.

[0013]

According to the steering load device of the present invention, the steering angle of the steering wheel detected by the steering angle detecting section, the steering angular velocity of the steering wheel detected by the steering angular velocity detecting section, and the moving speed of the moving body are compared with the steering wheel. The load to be given is set. Therefore, the load is set based on both the restoring force of the steering generated based on the structure of the actual vehicle and the resistance against the steering angular velocity, and moreover, the load different for each running course is set by the initial data setting means. Initial data for setting is input, and the value of the steering load set by the load setting unit described above is changed according to the input initial data for each traveling course. Therefore, since the optimum steering load can be freely set for each traveling course, a steering operation feeling closer to actual driving can be obtained.

According to the steering device of claim 2,
The restoring force described above is calculated by the restoring force calculation means. Then, the respective calculation results are added by the addition means, and the load setting described above is performed based on the addition result. Therefore, each of the restoring force and the resistance force is accurately obtained, and all of them are reflected in the steering load, so that a realistic steering operation feeling can be obtained.

The steering wheel 22 is configured so that when the steering wheel 10 is rotated, the shafts 24 and 28 connected to the steering wheel 10 also rotate.

The servo motor 30 functions as a load device that gives a variable load to the steering wheel 22, and this load is controlled by the servo voltage E output from the servo controller 40.

The potentiometer 38 is used for the steering 2
This is for detecting the rotation state of No. 2. Shaft 2
8. Pulley 32 and potentiometer 38 attached to 8
The pulley 34 attached to the rotary shaft of the is connected by a belt 36, and when the steering 22 is rotationally operated, the steering shaft 28 rotates, and at the same time, the potentiometer 38 also rotates by a certain angle. There is. The potentiometer 38 is configured to detect and output the rotation of the rotating shaft as a resistance change.

The angle calculation unit 42 includes a potentiometer 38.
The steering angle θ of the steering wheel 22 is calculated according to the output (resistance). The angle calculator 42 and the potentiometer 38 described above function as a steering angle detector.

The angular velocity calculation unit 44 includes a potentiometer 3

The fluctuation amount of the resistance value per unit time, which is the output of, is calculated as the steering angular velocity ω. The angular velocity calculator 44 and the potentiometer 38 described above function as a steering angular velocity detector.

The steering angle θ and the steering angular velocity ω calculated by these two calculation units 42 and 44 are both input to the servo controller 40. Servo controller 4
0 calculates the servo voltage E input to the servomotor 30 based on the input steering angle θ and steering angular velocity ω and various parameters P1, P2, P3. Details of this arithmetic operation will be described later.

The restoring force parameter memory 46 stores the relationship between the vehicle speed v of the racing car driven by the player and the restoring force parameter P1 in the form of a table.

Similarly, the resistance parameter memory 48 is

Both the vehicle speed v and the initial data from the data setting unit 54 described later are input as addresses. The resistance force parameter P2 corresponding to the vehicle speed v is output. The parameters P1 and P2 output from the memories 46 and 38 are input to the servo controller 40.

The above-mentioned servo controller 40, restoring force parameter memory 46, and resistance force parameter memory 48 function as a load setting section.

The game calculation section 50 is for performing various game calculations relating to the drive game of the present embodiment, and depending on the operation status of the operation input section 62 including the accelerator 12, the brake 14, the shift lever 16, etc., the drive game. To expand. Further, the result is sent to the display control unit 52,
Various image data created by the display control unit 52 is displayed on the display 20. For example, a front view that can be viewed through the front window of the racing car driven by the player is displayed on the screen of the display 20.

The data setting section 54 is for freely changing and setting the load of the steering wheel 22, and a ten key 55 for inputting various data and a ten key 55.
When the data corresponding to the traveling course is input by operating the, the memory 6 for temporarily holding this data
0 and two keys that store these initial data for each running course when the initial data given to each of the restoring force parameter memory 46 and the resistance force parameter memory 48 by operating the ten keys 55 are input. It includes memories 56 and 58. The relationship between the initial data and the restoring force parameter memory 46 and the resistance force parameter memory 48 will be described later.

Further, the two memories 56 and 58 for storing the initial data for each traveling course described above are constituted by non-volatile memories, and the contents thereof are retained even after the power is turned off. ing. Therefore, once the initial data for each traveling course is input, it is not necessary to input the initial data every time the traveling course is changed, and the labor of data input can be saved. Next, details of a method of calculating the servo voltage E input from the servo controller 40 to the servo motor 30 will be described.

The load applied to the steering wheel 22 of this embodiment is a combined force of restoring force and resistance force. Here, the restoring force is a force to return the steering wheel 22 to a predetermined position, and the resistance force is a force to oppose the steering angular velocity of the steering wheel 22.

FIG. 3 is a diagram for explaining the cause of generation of the restoring force. As shown in FIG. 1A, in an actual vehicle, a tire 72 is attached to the tip of a steering shaft 70 forming a caster angle φ. As described above, since the steering shaft 70 has the constant caster angle φ, straightness is produced when the vehicle travels, and a restoring force that causes the steering wheel 22 to return to a predetermined position is generated.

Further, FIG. 3B shows the steering shaft 70 and the tire 7.
2 is seen from the front of the vehicle, the steering shaft 70
Since the axial direction of the steering wheel and the rotational axis direction of the tire 72 are deviated from 90 °, a restoring force that causes the steering wheel 22 to return to a predetermined position due to the vehicle weight is generated.

As described above, it is considered that the restoring force is generated mainly by the above two causes.

Since there is a certain frictional resistance between the tire 72 and the road surface, when the steering wheel 22 is turned off, a resistance force against the steering angular velocity of the steering wheel 22 is generated according to the magnitude of this frictional resistance. To do.

When the resistance force is W and the restoring force is C, it can be expressed as W = ω × P2 C = (θ-P3) × P1. Here, P1 is a restoring force parameter, P2 is a resistance force parameter, and P3 is a center parameter.

FIG. 4 is a diagram for explaining the restoring force parameter P1 and the resistance force parameter P2. In the figure (A), the vertical axis represents the restoring force parameter P1 and the horizontal axis represents the vehicle speed v.
Respectively. As shown by the curve a, the vehicle speed v
The resilience parameter P1 also increases with increasing. Therefore, according to the formula (C = (θ-P3) × P1) of the restoring force C and the restoring force parameter P1 described above,
It can be seen that the restoring force C increases as the vehicle speed v increases. However, the vehicle speed v and the restoring force parameter P1 are not directly proportional to each other, and the increasing tendency of the restoring force parameter P1 becomes gentle as the vehicle speed v increases, and the restoring force parameter P1 is almost saturated in the high speed region.

In FIG. 6B, the vertical axis represents the resistance parameter P2 and the horizontal axis represents the vehicle speed v. As shown by the curve b, the resistance parameter P2 sharply decreases as the vehicle speed v increases. Therefore, the equation (W = ω
If only the resistance force W is considered as the load by × P2), when the steering wheel 22 is rotated at the same angular velocity ω, the smaller the vehicle speed v, the heavier the weight becomes, and the larger the vehicle speed v, the lighter the weight becomes. However, the resistance parameter P
2 drops sharply in the low speed region and saturates to a certain value in the high speed region.

Further, the curve group shown in FIG. 4A shows the vehicle speed v and the restoring force parameter P1 when the initial data input to the data setting section 54 and stored in the memory 58 is changed.
It shows how the relationship with and changes. One curve in the curve group is one to one for some initial data
, And the respective curves have a relationship in which they are translated in the horizontal direction. Therefore, by changing the initial data, the restoring force parameter P1 is large when the vehicle speed v is the same and is small when the vehicle speed v is the same, and the value of the initial data to be input for each traveling course is changed. By changing it, the magnitude of the restoring force C can be changed.

Similarly, in the group of curves shown in FIG. 4B, when the initial data input to the data setting section 54 and stored in the memory 56 is changed, the vehicle speed v and the resistance parameter P
It shows how the relationship with 2 changes.
Similar to the case of the restoring force parameter P1 described above, one curve in the curve group corresponds to one initial data in a one-to-one correspondence, and the respective curves have a relationship in which they are translated in the horizontal direction. is doing. Therefore, by changing the initial data, the resistance parameter P2 is large when the vehicle speed v is the same, and the resistance parameter P2 is small when the vehicle speed v is the same. By changing it, the magnitude of the resistance force W can be changed.

The restoring force C is determined by the deviation between the steering angle θ and the restoring force center (P3). The above formula of the restoring force C and the center parameter P3 (C = (θ-P3)
XP1), the center parameter P3 indicates the center of the restoring force of the steering angle θ, and it can be seen that the restoring force C proportional to the deviation (θ−P3) from the center position is generated. The center parameter P3 is constant regardless of the vehicle speed v, and a preset value is input from the game calculation section 50 to the servo controller 40.
By changing the center parameter P3 during the game, it is possible to reproduce the phenomenon that the steering wheel 22 is taken when a cross wind is received, a puncture occurs, a step is climbed, or an abnormality occurs in the tire. It is also possible to do.

As described above, by appropriately setting the initial data input to the data setting section 54, that is, the values of the initial data stored in the memories 58 and 56, the restoring force C and the resistance force W with respect to the vehicle speed v can be set as necessary. The steering wheel 22 can be made heavier when traveling on a circuit course, for example. On the other hand, when driving on an urban course, the steering wheel 22
Can be lightened.

The servo controller 40 includes an angle calculator 4
2, the steering angle θ, the steering angular velocity ω input from the angular velocity calculation unit 44, and the restoring force parameter memory 46.
From the restoring force parameter P1 output from the resistance force parameter memory 48
And the center parameter P input from the game calculation unit
The resistance force W and the restoring force C described above are calculated based on 3 and the resultant force (W + C) obtained by adding these forces is calculated. Then, the servo voltage E is calculated by multiplying the combined force by a constant coefficient K, and the calculated servo voltage E is applied to the servo motor 30.

Therefore, a new resistance force W, is generated whenever the steering angle θ, the steering angular velocity ω or the vehicle speed v changes.
The restoring force C is calculated, and the servo voltage E according to the progress situation of the game and the operation situation of the player is applied to the servo motor 30. For this reason, the load of the steering wheel 22 changes in real time according to the situation, and a realistic steering steering feeling closer to that of an actual vehicle can be obtained.

FIG. 5 is a diagram showing a detailed structure of the servo controller 40 for performing such calculation. As shown in the figure, the servo controller 40 has three multiplication units 7
4, 77 and 80, and one subtraction unit 76 and one addition unit 78, respectively.

The multiplying unit 74 multiplies the input resistance force parameter P2 by the steering angular velocity ω to obtain the resistance force W.
Is calculated. The calculated resistance W is input to the adder 78.

The subtractor 76 subtracts the center parameter P3 from the input steering angle θ to calculate the deviation (θ-P3) between the present steering angle θ and the center of the restoring force.
The calculated value is input to the multiplication unit 77.

The multiplying unit 77 calculates the restoring force C by multiplying the input restoring force parameter P1 and the calculation result (θ-P3) by the subtracting unit 76. The calculated restoring force C is input to the adder 78.

The adder 78 calculates the combined force by adding the resistance W input from the multiplier 74 and the restoring force C input from the multiplier 77. The multiplication unit 80 multiplies the resultant force by a constant coefficient K and outputs the servo voltage E to the servo motor 30.

Next, the procedure for inputting the initial data for each course from the data setting unit 54 in the game device having such a configuration will be described. FIG. 6 is a diagram for explaining the flow of operations at the time of inputting initial data.

When setting the load on the steering wheel 22 for each traveling course, that is, for each circuit course or city area course, first, the data setting section 54 is set by the player or the like.
Is operated to input a traveling course for setting initial data (step 601). For example, the number "0" unique to each of the circuit course and city area course,
"1", ... Are associated with each other, and the course is input by operating the ten keys 55 to input these values. Data input from the numeric keypad 55 is stored in the memory 6
It is held at 0. Further, the course number held in the memory 60 is input to the memories 58 and 56 as an address.

Next, initial data (restoring force designation data) for specifying which curve shown in FIG. 4A is used to calculate the restoring force parameter P1 is input (step 602). As the restoring force designation data, for example, a value between “0” and “40” is input, and a smaller value designates a curve located on the left side, and a larger value designates a curve located on the right. It has become so. This restoring force designation data is directly input by the player or the like by operating the ten keys 55.

The resilience designating data thus input is stored in the memory 58 (step 603). As described above, in the memory 58, since the course number held in the memory 60 is designated as an address, the restoring force designation data input at the steering wheel 602 can be stored in different storage areas for each traveling course. ing. Also, this memory 58 (same for the memory 56) is
Since it is a non-volatile memory, once set data is stored unless it is changed, and it is not necessary to input initial data every time the traveling course is changed.

Next, initial data (resistive force designation data) for specifying which curve shown in FIG. 4B is used to calculate the resistive force parameter P2 is input (step 604). The input resistance force designation data is stored in the memory 56 in the same manner as in the case of the restoring force designation data described above (step 605).

Next, a confirmation operation is performed by the player who inputs various initial data. That is, the player operates the ten keys 55 of the data setting section 54 to input a specific value as the vehicle speed v (step 60).
6) Confirm whether or not an appropriate load is applied by actually moving the steering wheel 22 (step 60).
7).

When a specific vehicle speed v is set, this vehicle speed v is input from the game calculation section 50 to each of the restoring force parameter memory 46 and the resistance parameter memory 48, and this memory speed is input from each of the memories 46 and 48. The restoring force parameter P1 and the resistance force parameter P2 are read out and output based on the vehicle speed v and the respective initial data previously input in steps 602 and 604. When the player or the like moves the steering wheel 22, the steering angle θ is output from the angle calculation unit 42, the steering angular velocity ω is output from the angular velocity calculation unit 44, and a servo voltage E is output from the servo controller 40. Therefore, the servomotor 30 operates the steering wheel 2 based on the servo voltage E.
A predetermined load is generated for 2, and the player or the like can actually experience this load.

Such an operation is performed, for example, at a vehicle speed of 0 and a vehicle speed of 40 Km / h, and it is confirmed by the player who inputs the initial data that the operation feeling of the steering wheel 22 is appropriate. If it is not appropriate, the initial data input after step 602 is redone. When the player determines that the operation feeling of the steering wheel 22 is appropriate, the input of the initial data of the traveling course of interest ends.

When a player plays a game by arbitrarily selecting a traveling course using the game device in which the initial data has been input and stored in this manner, first, the player uses the ten-key pad 55 of the data setting section 54. Is used to input the traveling course number (or the game calculation section 50 may set the traveling course). The input traveling course number is once held in the memory 60 and is input to the game calculation section 50.

Further, the course number of the traveling course which has been inputted and held in the memory 60 is inputted to the memories 58 and 56 as an address, and the already stored initial data of the traveling course is read out. The initial data read from the memory 58 is input to the resilience parameter memory 46, and the initial data read from the memory 56 is input to the resistance parameter memory 48. Each of the restoring force parameter memory 46 and the resistance force parameter memory 48 has a vehicle speed v and various parameters P1 and P2 depending on the value of the initial data input from the memory 58 or 54.
Since the content is set so that the relationship with the vehicle shifts as a whole, even if the vehicle speed v is the same, if the traveling course is different, the restoring force C and the resistance W are also different, and as a result, the load of the steering wheel 22 is increased. Is also variably set for each traveling course, and you can enjoy different steering intervals for each traveling course.

As described above, in the game device of this embodiment, the steering load is set based on the results of calculating the restoring force C and the resistance force W in consideration of the structure of the actual vehicle. It is possible to obtain a similar steering operation feeling.

The initial data for determining the load of the steering wheel 22 is stored for each running course, and the load state of the steering wheel 22 can be changed for each course. As a result, the steering wheel 22 is set lightly when a game is performed assuming a general vehicle traveling on an urban course, and the steering wheel 22 is set when a game is performed assuming a racing car traveling on a circuit course. Can be set heavy, and you can enjoy the game with realistic steering operation feeling.

Further, since the initial data is stored in different storage areas for different running courses, the corresponding initial data can be read and used every time the running course is changed, and the data can be read every time the course is changed. It is possible to save the trouble of inputting.

Further, since the steering operation feeling generated in the actual game can be experienced at the time of inputting the initial data, the load can be set faithfully even if the steering operation feeling varies from player to player. It can be performed.

The present invention is not limited to the above embodiments, but various modifications can be made within the scope of the gist of the present invention.

For example, in the embodiment described above, FIG.
Immediately after inputting the initial data, the memory 5
However, the registration key may be pressed to register (store) in each of the memories 58 and 56 after the confirmation operation by the memo player or the like in step 607 is completed.

Further, in the above-described embodiment, the servo voltage E is obtained by multiplying the result obtained by adding the resistance force W and the restoring force C evenly in the servo controller 40 by a constant coefficient K.
However, the resistance W and the restoring force C may be appropriately weighted and added (aW + bC). In this case, if the coefficients a and b are determined by measuring the steering load of the actual vehicle, a steering operation feeling with a higher degree of reality can be obtained. Further, although the resistance force W and the restoring force C are described as being proportional to the steering steering angle or the steering steering angular velocity, respectively, they may be related by a predetermined function other than proportional.

Further, in the above-mentioned embodiment, the steering load device in the arcade game machine has been described as an example, but the present invention can be applied to the steering load device of the driving simulator set in the driving school. In this case, an urban course or a high-speed running course can be considered as the type of teaching material, and the effect of the lesson can be further enhanced by realizing different steering loads for each of these courses.

The load applied to the steering wheel is set based on the speed and the speed. Therefore, the load is set based on both the restoring force of the steering generated based on the structure of the actual vehicle and the resistance against the steering angular velocity, and moreover, the load different for each running course is set by the initial data setting means. Initial data for setting is input, and the value of the steering load set by the load setting unit described above is changed according to the input initial data for each traveling course. Therefore, since the optimum steering load can be freely set for each traveling course, a steering operation feeling closer to actual driving can be obtained.

Further, according to the steering device of the second aspect, since the restoring force and the resistance force are accurately obtained and all of them are reflected in the steering load, a realistic steering operation feeling can be obtained. .
