Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a safety driving system for a game vehicle, for example, when a so-called go-kart capable of running on a running path provided in an amusement park without any qualification, such as a rear-end collision, is used. The present invention relates to a safe driving system for an amusement vehicle that can prevent a vehicle from running and can run safely.

[0002]

2. Description of the Related Art For example, a traveling course is provided in an amusement park or the like, and this traveling course is provided with a small displacement (for example, 30c).
c) Playing in a small vehicle (for example, go-kart) equipped with an engine has become popular. In particular, since the go-kart has a small engine and is designed to be safe, not only those who have a driving license, but also children and women who do not have a driving license can enjoy traveling,
It is one of the popular games in amusement parks.

The go-kart has substantially the same structure as a normal vehicle such as a passenger car, and is constructed using only indispensable members of the members constituting the vehicle such as a passenger car. Therefore, when running the go-kart, a switch corresponding to an ignition key is turned on to drive the engine. Further, the steering can be freely operated by operating a steering wheel provided on the driver's seat side. Of course, by the accelerator means and the braking means,
The running speed can be increased / decreased and stopped freely. Note that the go-kart is set at a low maximum speed (for example, 30 km / h) in order to enhance safety in consideration of the fact that children without a driving license mainly use the go-kart. In addition, in order to ensure the safety of the driver and other occupants even when an accident such as a rear-end collision occurs, elastic members such as rubber (for example, tires) are fixed to both front and rear ends of the vehicle to absorb impact. .

[0004]

However, there are the following problems to be solved in a game such as a go-kart provided in an amusement park or the like as described above. That is, as described above, a game vehicle such as a go-kart,
The structure prevents accidents from occurring during play as much as possible. In addition, even in the event of a collision, the above-mentioned elastic material absorbs the impact to improve safety. Therefore, it is considered that there is no danger of serious injury to the human body such as a driver as long as the driver enjoys normal driving. However, it is desirable to minimize the occurrence of the collision or other accident. In particular, since the above go-kart allows people who do not have a driving license to enjoy driving, if the driving skills are inexperienced, especially if children are driving, it will be on the side wall of the running road or other go-kart etc. May collide. In particular, when a steep curve is provided in the traveling course, there is a tendency that the number of collisions in the middle of such a curve increases as compared with a straight road. In addition, in the getting-on / off section for getting on / off the go-kart, braking may be suddenly performed at a position where the go-kart should be stopped, and as a result, it may relatively often collide with another go-kart in this getting-on / off area. It is difficult to prevent such a collision by the attention of the attendant. In the collision described above,
It is considered that serious harm is not given to the driver as described above, but it is desirable to take a countermeasure as long as safety is emphasized.

[0005] A safe driving system for a game vehicle according to the present invention has been devised in view of the above-described circumstances.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. In the safety traveling system for a game vehicle according to the present embodiment, a go-kart 1 as a game vehicle includes a traveling course 2 provided in an amusement park which is a non-public road.
In order to allow the vehicle to travel safely, the traveling state of the go-kart 1 can be controlled by command signals issued from a plurality of first and second transmitters 3, 4 provided on the traveling course 2 respectively. Things. The above go-kart 1

On the other hand, the second transmitter 4 is installed at the end of the steep curve or at the end of the go-kart 1 riding area. The end of the steep curve or the end of the go-kart riding area corresponds to the end of the section where the amusement vehicle has a high probability of causing an accident, as described in the claims. When the receiver 8 receives the command signal from the second transmitter 4, the microcomputer 7
Is configured to take a normal traveling mode in which the maximum speed of the go-kart 1 is a value based on the performance of the go-kart 1 (for example, the size and performance of the engine). Note that the first transmitter 3 and the second transmitter 4 are different from each other in the frequency of the command signal to be transmitted. This is because, for example, a command signal issued from the second transmitter 4 is received by the receiver 8 of the go-kart 1 that has reached near the position where the first transmitter 3 is installed, and the traveling state at the position is This is to prevent a danger caused by the microcomputer 7 executing a completely reverse command (in this example, the normal deceleration mode is changed to the deceleration mode). As described above, by setting the first transmitter 3 and the second transmitter 4 to have different frequencies, the command signals transmitted from the respective transmitters 3 and 4 can be accurately and reliably received by the receiver 8. , Appropriate control can be performed.

As described above, when the command signal transmitted from each of the transmitters 3 and 4 is received by the receiver 8 constituting the sensing unit 5 provided in the go-kart 1, control based on the command signal is performed. Is performed by the microcomputer 7. In the case of the present embodiment, the go-kart 1 includes a throttle actuator 9 for controlling a throttle opening of an engine (not shown) and a brake actuator 10 for operating a brake cylinder (not shown) to perform braking. ing. When the receiver 8 constituting the sensing unit 5 receives the command signal from the transmitters 3 and 4, the microcomputer 7 controls the throttle actuator 9 or the brake actuator 10 in accordance with the command signal. Control. Throttle actuator 9

It is unitized and fixed inside the go-kart 1.

In the present embodiment, the go-kart 1 is set to take one of the normal running mode and the deceleration mode by controlling the actuators 9 and 10 described above. The normal traveling mode is a mode in which the maximum speed based on the traveling ability of the go-kart 1 can be obtained. That is, this is a mode in which the throttle opening is maintained in a state where it is conventionally used.
On the other hand, in the deceleration mode, the maximum speed is a predetermined value (for example,
Mode in which the throttle opening is narrowed by a predetermined amount so that the speed becomes 10 km / h, or
This is a mode in which a so-called limiter conventionally provided in a passenger car or the like is provided, and the limiter is operated.

Further, in the case of this embodiment, the sensing unit 5
Along with the receiver 8, the vehicle speed sensor 11 and the headway sensor 1
2 is provided. The vehicle speed sensor 11 is
Conventionally used ones can be adopted. For example, a configuration in which the rotation speed of the axle is detected and the vehicle speed is calculated from the rotation speed can be adopted. By providing the vehicle speed sensor 11 as described above, based on the detection value of the vehicle speed sensor 11, the first transmitter 3 can be set in any of the deceleration mode and the normal traveling mode. It monitors whether or not each of the maximum speeds has been exceeded, based on the command signal issued from. Should the speed exceed the maximum speed for any reason, the microcomputer 7 controls the actuators 9 and 10 to a safe side (that is, to a side where the speed is reduced) to reduce the vehicle speed.

As the inter-vehicle sensor 12, a reflection type optical sensor is fixed to the front part of the go-kart 1, and the light emitted from the light emitting part of this optical sensor is reflected by an object existing in front of the go-kart. Thus, a configuration in which the distance to the object is measured from the time required to return to the light receiving portion of the optical sensor can be adopted. Inter-vehicle sensor 12 as described above
The distance between the go-kart 1 and the go-kart traveling in front of the go-kart 1 or the above-described object such as the side wall existing in front of the go-kart 1 is determined in advance based on the detection value of the inter-vehicle sensor 12. If it becomes smaller than the set distance (for example, 3 m),
The microcomputer 7 controls the actuators 9 and 10 to be on the safe side, and reduces the vehicle speed to increase the distance (increase the inter-vehicle distance).

In FIG. 1, reference numeral 13 denotes another go-kart 1
Is a reflecting plate for efficiently reflecting the light emitted from the inter-vehicle sensor 12. As the reflection plate 13, a conventionally known reflection plate is used, but a member that reflects light without scattering light is preferably used. Further, in the present embodiment, an example has been described in which the inter-vehicle sensor 12 is provided in front of the go-kart 1, but the inter-vehicle sensor 12 may be fixed to the rear part of the go-kart 1. Then, a distance to an object such as a go-kart or a side wall located behind the go-kart 1 is detected. If the detected distance is smaller than a preset distance (for example, 3 m), the microcomputer 7 The throttle actuator 9 is controlled (the vehicle speed is increased) to increase the inter-vehicle distance. In this case, a reflection plate 13 is provided at the front of the go-kart 1. Of course, the inter-vehicle sensor 12
May be provided on both the front part and the rear part of the go-kart 1. The inter-vehicle sensor 12 is provided to further improve the effect of preventing a rear-end collision or the like.

In this embodiment, despite receiving the command signal transmitted from the first transmitter 3,
A release switch (not shown) for releasing the deceleration mode by the command signal is provided. With such a configuration, for example, even in an area where a command signal to be set to the deceleration mode is issued, a person or the like having excellent driving skills can enjoy driving at will. Alternatively, for example, in a case where it is desired to stop at a predetermined position for performing a change of driving in a getting-on / off area of a traveling course, the deceleration mode is set in the area, but the deceleration mode can be canceled to quickly reach the predetermined position. Become like Further, the microcomputer 7 turns on (turns on) a power switch (not shown) corresponding to an ignition switch of a normal passenger car or the like in order to drive the go-kart 1, thereby turning on the vehicle speed sensor 11 and the headway sensor. 12, a circuit (not shown) for diagnosing the operation of each component such as each of the actuators 9, 10 can be incorporated. As this circuit, a circuit for self-diagnosis employed in various devices can be used. If such a circuit is provided so as to diagnose the above-mentioned constituent members 9, 10, 11, 12, etc., the go-kart 1 is inspected before traveling, thereby contributing to safer traveling.

In FIG. 1, reference numeral 15 denotes the seat 1 of the go-kart 1.
The operation box 15 is provided with lamps for notifying the operator that an abnormal portion is found when diagnosed by the circuit. Further, the operation box 15 is provided with manual switches so that each component can be operated manually without using the microcomputer 7. Further, in FIG. 1, reference numeral 6 denotes a control panel provided in the vicinity of the operation box 15. The microcomputer 7 is provided on the control panel 6, and a stable power source is secured from the generator of the engine of the go-kart 1. A stabilizing power supply 16 is provided. The stabilizing power supply 16 serves as a power supply for the electric system of the go-kart 1 together with the battery 17 mounted at the rear of the go-kart 1.

By using the safe driving system according to the present embodiment configured as described above, the above-described collision accident can be prevented beforehand, and safety can be improved. That is, as shown in FIG. 2, the first transmitter 3 is installed at an entrance C in a section where a collision accident or the like easily occurs, such as an entrance of a sharp curve or an entrance of a go-kart 1 riding area. Thereby, when the go-kart 1 reaches the vicinity of the position C, the receiver 8 provided in the go-kart 1
Receives the command signal transmitted from the first transmitter 3, and the microcomputer 7 controls the go-kart 1 in a deceleration mode and controls the go-kart 1 to a safe side such as lowering the maximum speed. When the distance sensor 12 detects that the distance from another go-kart or the like has been reduced, the microcomputer 7 controls the brake actuator 10 to automatically perform braking to prevent a rear-end collision accident or the like. I do. Further, for example, when it is desired to reduce the distance between the vehicles to get on and off the boarding area, the release switch is turned on to release the deceleration mode, so that the distance between the vehicles can be reduced quickly.

Until the go-kart 1 reaches the position C, the go-kart 1 is running in the normal running mode. In the case of the normal traveling mode, when the possibility of collision is detected by the inter-vehicle sensor 12, the microcomputer 7 controls the actuators 9 and 10 so as to increase the inter-vehicle distance. On the other hand, by passing through the position C, the go-kart 1 enters the deceleration mode.
Thereby, the microcomputer 7 adjusts the throttle opening so as to limit the maximum speed to a predetermined value (for example, 10 km / h). At the same time, the microcomputer 7 controls the brake actuator 10 based on the detection value of the headway sensor 12 to automatically perform braking. As a result of the above, safe traveling is ensured, and, for example, a rear-end collision or the like is prevented.

Further, the second transmitter 4 is installed at a position where a collision accident or the like does not occur so much, such as at an exit of a sharp curve or at an end position S of a riding area of the go-kart 1. Thus, when the go-kart 1 reaches the S position or the like, the receiver 8 provided in the go-kart 1 receives the command signal issued from the second transmitter 4, and the microcomputer 7 The deceleration mode of the go-kart 1 is released to return to the normal running state. Thereafter, the go-kart 1 maintains the normal running mode up to the position where the first transmitter 3 is installed. For this reason, go-kart 1 for drivers etc.
A person who enjoys traveling is limited to a maximum speed (for example, 30 km / h) based on the traveling ability of the go-kart 1,
It becomes possible to drive according to the driver's intention.

Since the safety driving system according to the present embodiment is constructed and operates as described above, even if the person who drives the go-kart 1 is an inexperienced driving skill such as a child, it may cause a rear-end collision or the like. Since the deceleration mode is automatically set in sections where the occurrence is likely to occur, extremely safe driving is possible. Moreover, in a section in which a rear-end collision or the like is unlikely to occur, the vehicle automatically enters the normal traveling mode, so that the driver can enjoy traveling as desired. In other words, the present embodiment enables the go-kart 1 to travel safely without impairing the intention of the driver or the like as much as possible. Furthermore, if the sensing unit 5 having the receiver 8 and the like and the control panel 13 and the like having the microcomputer 7 and the like are unitized, it can be mounted on a conventionally used gokato, which is economical. Of course, running course 2
Of these, the first transmitter 3 is provided at the beginning of a section where a rear-end collision or the like is likely to occur, and the second transmitter 4 is provided at the end of this section.
Is installed. Therefore, the unit, the first and second transmitters 3,
The safe driving system according to the present invention can be easily and inexpensively realized only by installing the four.

In the above-described embodiment, a go-kart is described as an example of a game vehicle, but the safety driving system for a game vehicle according to the present invention is not limited to this embodiment. In recent years, motor sports have become widespread, and various amusement vehicles have appeared. For example, there are amusement vehicles such as so-called zero hanker, an off-road buggy type racing car equipped with an engine with a displacement of 50 cc, a racing cart similar to the go-kart, and a so-called aqua cart running on water. These vehicles are used for races (time races) performed by like people. When a beginner practices these vehicles, the present invention can be applied to enable safe driving practice. In this case, the control unit 13 and the like including the sensing unit 5 and the microcomputer 7 are unitized and detachable from the vehicle.

[0028]

The safety driving system for a game vehicle according to the present invention is constructed and operates as described above, so that the person who drives the game vehicle is an inexperienced person such as a child. However, in a section where a rear-end collision or the like is likely to occur, the traveling state is automatically controlled to the safe side, so that extremely safe traveling becomes possible. In addition, in a section where a rear-end collision or the like does not occur so much, the normal driving mode is automatically set, so that the driver can enjoy driving as desired. In addition, if the sensing unit and the control means are unitized and can be attached to and detached from the amusement vehicle, it can be mounted on a conventionally used gokato, which is economical. Of course, in the traveling course, the first transmitter is installed at the beginning of a section where a rear-end collision or the like is likely to occur, and the second transmitter is installed at the end of this section. Therefore,
