Trace point data (distance storage means) in the world coordinate system and enemy vehicle control point data are stored.
The RAM 24 temporarily stores data and the like.

The control unit 25 is composed of a CPU, a logic circuit, and the like, performs various calculations at a predetermined sampling period, controls the operation of each unit using the calculation results, and displays an image on the monitor 2. Things. Further, it is determined whether or not a coin has been inserted into the coin insertion slot 8 (FIG. 16) based on the presence or absence of a detection signal sent from the coin detection unit 21.
It is determined whether or not the start switch 9 has been pressed by the player based on the presence or absence of the switch signal from the player.

Further, the control unit 25 performs control for changing the traffic light to blue, yellow, and red at a predetermined cycle, and control for lowering the crossing barrier at a predetermined timing (traffic light control means).

The own vehicle control unit 251 of the control unit 25 stores the operation data of each unit transmitted from the driving operation unit 22 and the ROM 2
The control of the running of the own vehicle is performed using the vehicle behavior program according to the vehicle engineering stored in the storage device 3.

In FIG. 2, the steering wheel operation amount detecting section 511, the accelerator operation amount detecting section 512 of the own vehicle control section 251,
The brake operation amount detection unit 513 and the side brake operation amount detection unit 514 include an A / D converter and the like, and operation data transmitted from the steering wheel 4, the accelerator pedal 5, the brake pedal 6, and the side brake 7 of the driving operation unit 22, respectively. , The operation amount of each unit is detected.

The vehicle speed calculation section 515 calculates the vehicle speed using the detected operation amounts of the accelerator pedal 5 and the brake pedal 6. The lock condition determination unit 516 determines whether or not the rear wheels are locked using the detected operation amount of the side brake 7, the calculated vehicle speed, and the lock condition table data stored in the ROM 23. .

The slip condition judging section 517 calculates the detected operation amount of the steering wheel 4, the calculated vehicle speed, the judgment result of the lock condition judging section 516, and the slip condition table data in the locked and unlocked states stored in the ROM 23. Is used to determine whether the vehicle is in a slip state.

The movement processing section 518 includes the detected operation amount of the steering wheel 4, the calculated vehicle speed, and the slip condition determination section 51.
The moving process of the own vehicle is performed using the determination result of 7 and the vehicle behavior program according to the vehicle engineering stored in the ROM 23.

Here, the effect of the side brake will be described. The side brake that applies a braking force only to the rear wheel locks the rear wheel depending on conditions. Therefore, the own vehicle control unit 251 divides the rear wheels into two states, a locked state and an unlocked state. Normally, the rear wheels are in the unlocked state, and are locked when the side brake 7 is operated at a predetermined level or more. This predetermined level is set according to the vehicle speed of the own vehicle as shown in FIG.

On the other hand, the direction of a running car can be changed by operating the steering wheel. If you operate the steering wheel more, you can make a smaller turn, but if you operate the steering wheel more at high speed, the tire loses frictional force,
A slip condition occurs. Therefore, the own vehicle control unit 251
By using a vehicle behavior program in accordance with automotive engineering, the moving process is performed by different calculations in the slip state and the non-slip state.

Whether the vehicle is in the slip state is determined by the steering wheel 4.
Is set according to the operation amount of the vehicle and the vehicle speed of the own vehicle. When the rear wheel is in the locked state, even if the operation amount of the steering wheel is small, the vehicle immediately enters the slip state. Therefore, as shown in FIGS.
The conditions under which the slip condition occurs when the rear wheel is unlocked and when the rear wheel is locked are different.

The behavior of the slip state when the rear wheels are locked and when the wheels are not locked is basically the same. However, when the rear wheels are locked, the responsiveness of the steering wheel is higher, and the overall operation of the vehicle is more sensitive. can do.

Next, the general vehicle control unit 252 will be described with reference to FIGS. FIG. 6 is a diagram showing a part of an urban road 12 showing a traveling course of a general vehicle. The general vehicle control unit 252 controls the running of a plurality of general vehicles functioning as obstacles on the city road 12, and controls the running of each general vehicle sequentially.

The general vehicle control section 252 moves each general vehicle along a trace point set corresponding to the world coordinate system. This trace point, for _{example, TP A (x A, y} A, z A, r xA, r yA, r zA) TP B (x B, y B, z B, r xB, r yB, r zB) of as such, the coordinates (x, y, z) and the gradient (r _x, r _y,
r _z ).

On the other hand, the control unit 25 operates at 29 (interruption / second), and the movement of 1 (cm / interruption) is about 1 km / h (speed).
Is equivalent to Therefore, in order to move a general car smoothly, it is necessary to set trace points finely. In that case, however, the amount of data becomes enormous, and it is difficult to perform monitor display in real time.

Therefore, in this embodiment, trace points are set at intervals of about 1 m, and the interval is divided into 32 on the game program. By this, about 3km /
The vehicle speed can be changed in h units.

That is, the general vehicle control unit 252 controls the vehicle speed of the general vehicle based on the trace speed, which is the number of division points that advance in one interrupt. For example, if a trace point starts moving at a trace speed of 10, 16
The fifth trace point is reached after the interruption.

As shown in FIG. 6, the trace points are set on courses C1 to C6, on which ordinary cars can run. On course C3, a running course is set. Changeable points CP4 to CP6 that can be changed to C4 to C6 are provided.

In courses C4 to C6, the maximum number of general vehicles that can be run is set in advance, and the change point CP4
When the vehicle reaches CP6, the number of ordinary vehicles traveling on the courses C4 to C6 is determined. If the number is less than the maximum number, the course change condition is satisfied, and the course is changed by a random number.

During normal traveling, calculation is performed using only the two-dimensional coordinates (x, y) of the trace points, and the distance is calculated based on the number of trace points. We are trying to shorten it.

In FIG. 1, a general car discriminating section 521 discriminates whether or not another general car is present at an intersection in front of the vehicle. Is set, and it is determined based on whether or not another general vehicle exists in this section.

For example, in FIG. 6, when a general vehicle traveling on the course C3 approaches the intersection K on the right end, if the general vehicle on the course C2 is traveling in the section A, another general vehicle is present. Then, it is determined.

Returning to FIG. 1, the distance calculation section 522 calculates various distances related to the traveling of a general car. For example, the distance to a stop line at an intersection where a traffic signal is ahead, and the forward direction in the same direction The distance to another general vehicle traveling at a distance is calculated (fork-point distance determining means).

The host vehicle enemy vehicle determining unit 523 determines whether the host vehicle or the enemy vehicle is present in front, and calculates the distance when the host vehicle or the enemy vehicle is present, and the calculated distance is smaller than the preset distance. In the case of, the fact is output to the vehicle speed control section 524 and the movement processing section 525 (the own vehicle distance determining means, the enemy vehicle distance determining means). The vehicle speed control unit 524 controls the vehicle speed of a general vehicle using the calculation result of the distance calculation unit 522 and the determination result of the own vehicle enemy vehicle determination unit 523.

The movement processing unit 525 performs the movement processing of the ordinary vehicle at the vehicle speed controlled by the vehicle speed control unit 524, and performs the avoidance operation for the own vehicle or the enemy vehicle based on the result of the determination by the own vehicle enemy vehicle determination unit 523. The coordinate data after the movement is sent to the position determination unit 254.

According to the movement processing unit 525, as shown in FIG. 6, when the general vehicle traveling on the course C3 to be controlled approaches the intersection K at the right end in FIG. When it is determined that there is another general vehicle while traveling in A, the vehicle stops before section B.

Next, returning to FIG. 1, the enemy vehicle control unit 253,
The position determining unit 254 and the drawing processing unit 255 will be described. The enemy vehicle control unit 253 controls the traveling of the enemy vehicle competing with the own vehicle, and details thereof will be described later.

The position judging section 254 includes a host vehicle control section 251,
Using the coordinate data of each vehicle sent from the general vehicle control unit 252 and the enemy vehicle control unit 253, all vehicles existing within a preset visibility range are searched, and data relating to the vehicles within the searched visibility range is drawn. This is sent to the unit 255.

The position determination unit 254 determines the positional relationship between the own vehicle and a general vehicle or an enemy vehicle, such as contact or collision, and the positional relationship between the own vehicle and a road edge. When it is determined that contact or collision has occurred between the vehicle and the road edge, a collision signal is sent to the drawing processing unit 255.

Note that the determination of the positional relationship is performed using only two-dimensional (X, Y) coordinate data. As a result, the arithmetic processing can be performed at high speed, so that the processing can be performed in real time even when the number of ordinary vehicles increases, and the complexity of the game can be increased to make the game more interesting.

The viewpoint position is a preset distance behind the own vehicle and is set slightly above, the line of sight is set in a direction corresponding to the direction of the own vehicle, and the view range is The distance is set by the left and right angles to the direction of the own vehicle and the distance from the viewpoint position.

The drawing processing unit 255 performs geometry processing and rendering processing on all the vehicles searched by the position determination unit 254, the model of the city road 12 (FIG. 13) within the visibility range, and the buildings around the city road 12 and the like. A known three-dimensional image processing such as that described above is performed and displayed on the monitor 2.

When displaying the city road 12, the roads of the necessary blocks located within the visibility range are displayed (see FIG. 15). When the direction of the vehicle changes, the road coordinate data is rotated and displayed in a direction opposite to the change direction.

Further, the drawing processing section 255 includes the position determination section 2
When the collision signal is transmitted from the monitor 54, the monitor 2 displays a screen that spins and vibrates.

The drawing processing section 255 displays the course map shown in FIG. 14 on the monitor 2 and also displays the position of the own vehicle in dots on the course map (map display processing means). This course map shows the vehicle control unit 2
The traveling direction of the own vehicle obtained from 51 is displayed as a reference. For example, when the own vehicle turns left at an intersection, the course map to be displayed is rotated to the right in the opposite direction and displayed.

As a result, the player can always see the course map centering on the own vehicle, and thus can immediately grasp the positional relationship of the own vehicle on the course map. Conventionally, the position of the own vehicle is displayed in dots on a fixed course map. In this case, when the own vehicle is moving forward, a dot indicating the own vehicle on the course map is displayed. When the vehicle descends, it is necessary to consider the road shape in front of the vehicle as being uncomfortable or inverting the shape of the road ahead. According to the above-described embodiment, such a problem is eliminated, and the shape of the road ahead can be easily understood. .

In this game machine, as shown in FIG. 14, a course map representing the city road 12 in two-dimensional coordinate data is displayed on the monitor 2. In FIG. 14, triangles or squares each surrounded by a straight line form one polygon plane.

Next, the operation procedure of the driving game machine will be described. FIG. 7 is a flowchart showing a main routine of the driving game machine.

When the power is turned on, a demonstration screen is displayed on the monitor 2 by the drawing processing unit 255 (step S1).
0). Next, it is determined whether or not a coin has been inserted into the coin insertion slot 8 (step S20). If no coin has been inserted (NO in step S20), step S10 is performed.
Is continued (YES in step S20), a start screen is displayed by the drawing processing unit 255 (step S30).

Next, it is determined whether or not the start switch 9 has been pressed (step S40). If the start switch 9 has not been pressed (NO in step S40), the display of the start screen in step S30 is continued, and the start switch is displayed. When 9 is pressed (YES in step S40), the game is started, and the player operates each part of driving operation unit 22 to run the own vehicle.

Then, the operation data of each part transmitted from the driving operation unit 22 is taken into the own vehicle control unit 251 (step S50), and the simulation processing according to the vehicle engineering is performed according to the vehicle behavior program stored in the ROM 23. The process is performed (step S60), and the position data of the world coordinates of the own vehicle determined in this process is updated (step S70).

Next, the ordinary vehicle control unit 252 performs ordinary vehicle traveling processing described later (step S80), and updates the world coordinate position data of the ordinary vehicle determined in this processing (step S90). Enemy car control unit 253
The enemy vehicle running process to be described later is performed (step S10).
0), the position data of the world coordinates of the enemy vehicle determined in this process is updated (step S110).

Next, the position judging section 254 searches for all vehicles located within the field of view (step S120).
From the position and orientation of the own vehicle determined by the simulation processing performed in step S60, the drawing processing unit 25
5, the image is displayed on the monitor 2 (step S130). Next, it is determined whether or not a preset time has elapsed from the start of the game (step S140). If it has not elapsed (NO in step S140), the process returns to step S50 to perform the same processing and repeat the traveling control. If the set time has elapsed (YES in step S140), the time is up and the processing ends.

The start of the game may be started by inserting a coin even if the start switch 9 is not pressed. Further, the game may be ended when the goal point of the city road 12 is reached, even if the set time has not elapsed.

FIGS. 8 and 9 are flowcharts showing a subroutine of step S80 in FIG. First, it is determined whether or not there are changeable points CP4 to CP6 ahead, and if there is a changeable point, whether or not to change the number of general vehicles of the changed course in consideration of whether or not the number is less than or equal to the set maximum number. Is determined,
When changing the course, the course is changed using a random number (steps S200 to S220).

Next, various states are determined (step S230). Here, the color of the traffic signal ahead, whether or not another general vehicle is present at the intersection in front, the distance to other general vehicles ahead, and the position of the own vehicle at a position less than the preset distance ahead. It is determined whether an enemy vehicle exists or not. The determination of the distance in this case is performed using the trace points.

Next, it is determined whether or not the own vehicle or the enemy vehicle is present at a position less than a short distance set in advance, and if there is, the operation is stopped (steps S240, S250).

Next, when the signal in front is red,
When the distance to the stop line is a very short distance (for example, one trace point), the vehicle stops. When the distance is a short distance (for example, 10 trace points), the vehicle decelerates. On the other hand, in the case where the signal is yellow, if the stop is possible by the stop line, the stop is performed, and if the stop is not possible, the process proceeds as it is (steps S260 to S290, S250).

Subsequently, when a general vehicle is present at the intersection in front of the vehicle, if the distance to the intersection is a very short distance (for example, one trace point, that is, less than the first distance), the vehicle stops. If the distance is a preset short distance (for example, 5 trace points, that is, more than the first distance and less than the second distance), the speed is reduced (steps S300 to S320, S250).

Next, when the distance from another general vehicle in front is a very short distance (for example, 3 trace points), the speed is changed to the same speed as that of the general vehicle, and the predetermined close distance (for example, 3 trace points) is changed. At the time of (7 trace points), the speed is reduced (steps S330 to S350).

Subsequently, it is determined whether the vehicle is in a normal traveling state, that is, not during deceleration or stopping, and when the own vehicle or the enemy vehicle is at a predetermined short distance (for example, 3 trace points) in the normal traveling state. If the vehicle is decelerated and is not in the normal traveling state, the traveling speed is changed to the reference speed (step S360)
To S390).

If the distance from the own vehicle or the enemy vehicle is a very short distance (for example, two trace points), a avoidance process for changing the direction is performed (step S400), and the process ends.

FIG. 10 is a flowchart showing a subroutine of step S100 in FIG. 7, FIG. 11 is a flowchart showing a subroutine of step S500 in FIG.
2 is a diagram of the city road 12 showing the enemy vehicle control points.

The enemy vehicle control unit 253 uses a plurality of enemy vehicle control points provided in advance on a predetermined course of the city road 12, as shown in FIG. 12, to control a plurality of enemy vehicles E _i (i = 1,..., K). It controls the traveling of the vehicle.

Then, the enemy vehicle control unit 253 sets the enemy vehicle control point at the start point to MP ₀ , the enemy vehicle control point at the goal point to MP _n ,
MP of the current target enemy vehicle control point while traveling between control points
_di , the sequence of enemy vehicle control points (MP ₀ ,…, MP _di ,…, M
P _n ) gives the traveling route R _i of the enemy vehicle E _i .

Referring to FIG. 10, first, a traveling route process described later is performed (step S500). Subsequently, are accelerated toward the rival car controlling point MP _di is the following purposes (step S510), the speed V _i is calculated (step S5
20). At this time, each enemy vehicle _Ei has a unique acceleration, and the traveling is controlled in consideration of the acceleration.

Next, the speed V _i and the preset speed V
The magnitude of the _MAX is determined, and the speed V _i is limited to V _MAX If V _i> V _MAX (Step S530, S540).
Then, the mobile processing of enemy vehicles E _i is performed (step S55
0), end.

Next, in FIG. 11, first, the enemy vehicle control point MP _dp closest to the host vehicle is determined (step S600).
The distance d between the enemy vehicle control point MP _dp and the own vehicle is calculated (step S610). That is, the enemy vehicle control unit 253 functions as a vehicle distance calculation unit.

Next, the magnitude of the calculated distance d and the preset distance D ₀ are determined (step S620).
This distance D ₀ is a value indicating the degree of separation of the own vehicle from the traveling route of the enemy vehicle, and if d ≧ D ₀ (step S620)
NO), since the own vehicle is sufficiently away from the current traveling route of the enemy vehicle, the subroutine is terminated without rewriting the traveling route.

On the other hand, if d <D ₀ (step S62)
0, YES), the shortest route _RA from the enemy vehicle control point MP ₀ at the start point to the enemy vehicle control point MP _dp closest to the host vehicle is obtained (step S630), and the current target enemy is placed on this route _RA. It is determined whether or not the vehicle control point MP _di exists (step S640), and if not, N is determined in step S640.
O), end as it is.

On the other hand, if the current target enemy vehicle control point MP _di exists on the route _RA (YES in step S640),
The enemy vehicle control point at the goal point from the enemy vehicle control point MP _di for this purpose
Route R _B leading to MP _n is determined (step S65
0).

[0143] Next, is connected root R _A and route R _B route R _C is obtained (step S660), rival car E _i
Travel route R _i of rewritten to the route R _C (Step S670), and ends. That is, the enemy vehicle control unit 253
Functions as a course changing means.

As described above, the enemy vehicle control point MP closest to the own vehicle
smaller than the distance D _{0 to dp} and the vehicle distance d is set in advance, and rival car control point from rival car controlling point MP ₀ of the starting point M
The current target enemy vehicle control point MP on the shortest route _RA to P _{dp
When di} is present, the driving route R _i of the enemy vehicle E _i is rewritten. If the distance between the host vehicle and the enemy vehicle becomes shorter while driving, the enemy vehicle may follow the own vehicle. Occurs. As a result, the realism of the competing driving game can be increased, and the game can be made more interesting.

Next, a description will be given of a modification in which players can compete with each other. In this modification, two driving game machines shown in FIG. 16 are connected to each other by a communication cable, and the control system of each driving game machine is:
In addition to the components of the above embodiment, a communication control unit 256 shown by a dashed line in FIG. 1 is provided, and a selection key (not shown) for selecting a competition between players is provided.

The communication control unit 256 transmits coordinate data relating to the position of the own vehicle to the other driving game machine, and controls the position of the own vehicle controlled by the other driving game machine, ie, the position of the communication vehicle of the present driving game machine. The coordinate data is received and transmitted to the position determination unit 254.

In this modification, the position determination unit 25
4 further determines the positional relationship between the own vehicle and the communication vehicle and the positional relationship between the ordinary vehicle and the communication vehicle, and also determines the communication vehicle located within the view range. When it is determined that contact or collision has occurred between the own vehicle and the communication vehicle, a collision signal is sent to the drawing processing unit 255.

The general vehicle control unit 252 performs similar determinations on the communication vehicle in addition to the own vehicle and the enemy vehicle, and the drawing processing unit 255 determines that the communication vehicle is located within the view range. If so, the communication vehicle is displayed on the monitor 2.

As described above, since the communication control unit 256 is provided to transmit and receive the position data relating to the own vehicle of each game machine, it is possible to further enhance the fun of the driving game by enabling the players to compete with each other. it can.

Next, a description will be given of an embodiment in which a game different from a car competition is played in the modified embodiment provided with the communication control section 256. In this game, there is a car corresponding to an "oniki", and a "game of tag" in which the "oni" is replaced by a contact between vehicles operated by each player.

In this embodiment, the position judging section 254 further judges a car corresponding to the "oni". Also,
It is determined whether or not the car corresponding to the “oni” has contact with another car, and if it is determined that the car has contacted, it is determined that the “oni” has replaced the car of the contact partner. Note that, at this time, the position determination unit 254 determines that the vehicles have a predetermined time (for example, 0.
If the contact continues for 3 seconds or more, it is determined that the "oni" has been replaced.

As shown in FIG. 18, the drawing processing unit 255 displays a time bomb Q (icon) having an ignited fuse above or around a car corresponding to an “oni”, and a position determination unit 254. If it is determined that the "oni" has been replaced, the display position of the time bomb Q is moved to a new "oni" as shown by the two-dot chain line in FIG.

The drawing processing section 255 counts the elapsed time from the start of the game, shortens the remainder of the squib at a predetermined speed as the time elapses, and sets the squib after a lapse of a predetermined time from the start of the game. After displaying the burnout state, an image is displayed as if an explosion occurred.

The drawing processing unit 255 is composed of a time-exploded bomb Q in the form of a plate using polygon data.
The polygon surface always faces the player, that is, the person operating the own vehicle of each driving game machine,
The time bomb Q is displayed on the monitor 2.

As described above, the presence or absence of contact between vehicles is determined, and it is determined that "oni" has been replaced by the contact, so that the driving game machine can be applied to a new "game of tag". It is possible to increase the fun of the game machine.

Further, when it is determined that the "oni" has been replaced when the vehicles continuously contact each other for a predetermined time or more, the time bomb Q frequently moves when the vehicles contact each other more than once in a short time. It can be prevented from becoming unsightly.

Further, the time bomb Q of a two-dimensional image is constituted by forming the time bomb Q having a flat plate shape with polygon data and displaying the polygon surface so as to always face the viewpoint of the player.

In the above embodiment, the time bomb Q is displayed in the vicinity of the vehicle to indicate that it is a demon, but the invention is not limited to this. For example, the entire vehicle may be flickered or the color of the vehicle may be changed.

Further, a communication control unit 256 is provided, and instead of performing a “game of tag” between driving game machines operated by each player, a plurality of driving games are performed in one driving game machine shown in FIG. The vehicle control unit 251 may include the operation unit 22, and may control the traveling of the vehicle corresponding to each player based on an operation signal from the driving operation unit 22 operated by each player. . In this case, a similar “game of tag” game can be enjoyed without including the communication control unit 256.
