2. Description of the Related Art Recreational vehicles widely used in amusement parks and the like are known as go-karts and are generally enjoyed by going around a circular course.

However, the conventional go-kart uses a gasoline engine as a prime mover, so that noise and exhaust are not only environmental problems, but also maintenance such as refueling and inspection of the engine and battery is troublesome. In addition, since the engine output, acceleration performance, steering performance, etc. are uniform, it is dangerous for those who are unfamiliar with driving a car, and on the contrary, those who are not satisfied with skilled people are limited in those who enjoy it enough Not only,
There is a danger of contact and rear-end collisions because people of various driving skills are mixed and run in a chaotic manner, so that skilled people often cannot demonstrate their skills.

On the other hand, attempts have been made to use a motor as a motor instead of a gasoline engine to obtain electric power by mounting a battery, but there is no environmental problem, but since high output cannot be obtained, only low-speed running is possible. In addition, there is a drawback that charging requires a long time and operation efficiency is extremely low.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a vehicle which is easy to maintain and has a high operating efficiency without causing environmental problems, and which is safe even if people of various driving skills are mixed. There was no recreational vehicle that could run with plenty of enjoyment and performance that matched its technology, and therefore also had no management system for it.
That is the point.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a motor vehicle, in which two traveling motors for driving a pair of left and right wheels respectively and another pair of left and right wheels are simultaneously steered. A steering motor, a current collector that obtains electric power from an external power supply line, and an instruction of the rotation speed of the traveling motor and the rotation speed of the steering motor based on the accelerator operation amount and the steering operation amount. And a microcomputer having a microcomputer capable of changing these control signal values and a collision detection device in addition to the above.

A driving performance limit is set by inputting a past required driving time of the driver or a value obtained by adding the number of times of collision to the past to a microcomputer as a criterion of a driving skill level, and power is supplied on a predetermined driving path. The vehicle was driven within the operating performance limit according to the driving skill level while obtaining power from the line.

[0008] Such a driving skill level allows each driver to carry a writable and readable electromagnetic storage card in which a driving record is stored, allows the microcomputer to set a driving performance limit with the card before running, and after driving, It is preferable to objectively make a determination by storing the current driving record in a card.

As described above, the object of providing a vehicle management system that changes the performance of a vehicle according to the driving skill level of the driver is achieved.

In addition, the traveling path is divided into a plurality of sections, and the power supply line is divided into sections, or in addition to this, a signal lamp is installed at the boundary of the section, and a car travels in one section. At that time, the power supply line in the adjacent rear section is cut off to maintain a certain inter-vehicle distance, or the driver is caused to travel while checking the situation in front.

As a result, the object of providing a course management system for preventing a rear-end collision of an automobile is attained, whereby the safe operation of the facility can be achieved.

The vehicle used in the present invention has a seat, a steering wheel, an accelerator pedal, and a brake pedal as in the conventional go-kart, but the rotation angle and rotation direction of the steering wheel and the amount of depression of the accelerator pedal are controlled by an encoder, a variable resistance. That it is converted into an electric signal by a detection means consisting of a device and is input to a microcomputer to give necessary control signals to the traveling motor and the steering motor, and in addition to these, the steering motor and the traveling motor in the event of a collision Is characterized in that it is controlled to turn in the avoiding direction. In addition, since these motors are required to have high acceleration performance and high responsiveness, it is preferable to use a servomotor which can easily obtain an instantaneous high output.

The electromagnetic storage device card is the same as a well-known card having an integrated circuit or a magnetic storage medium, but the structure is arbitrary as long as information can be written and read.

Further, the course for running such an automobile is generally formed in an annular shape so that it can make a round. However, it is preferable to provide a fence of an appropriate height on both sides of the running surface as a road surface so as to prevent departure. Preferably, the power supply line is laid in the air or on the ceiling along the running path, for example at a constant height.

Further, the microcomputer provided in the vehicle is divided into several stages and the driving skill level, and the operation limit performance, that is, the maximum speed, the maximum acceleration, the maximum deceleration, the minimum turning radius and the like are set for each stage. Preferably, these are stored in advance, and a control signal of a stage corresponding to the inputted driving skill level is issued. Alternatively, the control signal may be set in accordance with the highest performance of the vehicle, and may be changed to a low value according to the input driving skill level.

[0016]

In general, a lap course is formed by the power supply line and the traveling path, and the vehicle starts running after instructing the microcomputer of a driving performance limit corresponding to the driver's driving skill level. Although the rotational speed of the electric motor for traveling and the traveling speed are controlled in accordance with the accelerator operation amount, high-speed traveling is possible because electric power is supplied from the outside. In addition, the turning radius of the steering motor and the turning speeds of the left and right traveling motors are controlled in accordance with the steering operation amount, so that the vehicle can turn with a small radius without causing side slip. Further, when a collision is detected, a control signal for turning in the avoiding direction or decreasing the traveling speed is sent to each electric motor.

In the course, all vehicles keep a predetermined distance or more and travel without collision, but the number of collisions with the road shoulder and the required travel time are recorded, and the driving for the next travel is performed. Used to command performance limits.

Next, an example of a course and a management system will be described with reference to FIG. 4. A part of an annular traveling path 51 which is a combination of a straight line and a curve and has fences 52 at appropriate heights on both sides is used for getting on and off. And a power supply line 55 such as a trolley line is laid at a constant height above these. A start point A is set slightly ahead of the junction of the side path 54 of the travel path 51, and a goal point B is set slightly before the junction, and several checkpoints are set between them. Sensors C _A , C ₁ , C ₂ ,
C _3, C _B and progression, signal lights S _A for instructing the stop, S _1,
We established the _{S 2, S 3, S B} , these sections _{D 1, D 2, D 3} , power to separate the power supply line 55 for each D ₄ between each point and the checkpoint to each other It can be supplied and cut off.

A number of vehicles M ₁ , M ₂ ... Are on standby in the bypass 54, and the driver sets his driving performance limit by inserting his / her electromagnetic storage card into the card reader / writer of the vehicle M _1. I do. Then, when it is confirmed that the sensor C _A and the sensor C ₄ installed slightly before the confluence of the traveling path 51 are free from an automobile, the signal light S _A is turned blue to enable the vehicle to start.
