Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recreational electric vehicle that travels along a route defined by a power supply line and a travel route.

[0002]

2. Description of the Related Art Cars for entertainment which are widely used in amusement parks and the like are popularly known as go-karts, and generally enjoy around a circular route.

However, the conventional go-kart uses a small gasoline engine as a prime mover, and not only noise and exhaust are environmental problems, but also maintenance such as refueling and checking the engine and the battery is troublesome, and the outdoor go-karts are used outdoors. There is a problem that it requires a fairly large site. Furthermore, because engine output, acceleration performance, steering performance, etc. are uniform,
It is dangerous for young people and those who are unfamiliar with driving a car, and on the other hand, there is a problem that a person skilled in driving a car is unsatisfactory, and there is a problem that people who fully enjoy it are limited.

On the other hand, it has been attempted to use an electric motor as a prime mover instead of a gasoline engine to obtain electric power from a battery, but there is no environmental problem, but high output cannot be obtained, so that only low speed running is possible and charging is required. It has a drawback that it takes a long time and the operation efficiency is extremely low.

[0005]

The problem to be solved by the present invention is that it can be used both outdoors and indoors without environmental problems and can be fully enjoyed by people of various driving techniques. There was no easy-to-maintain car for entertainment.

[0006]

In order to solve the above-mentioned problems, the present invention separately drives a pair of left and right wheels by means of a transmission device including separate electric motors, and a pair of left and right wheels including an electric motor. The steering device is operated in conjunction with the steering device, and the microcomputer indicates the rotational speed of the driving electric motor and the rotational speed of the steering electric motor based on the driver's accelerator operation amount and steering operation amount.
Further, required power is supplied from an external power supply line by a current collector, and the microcomputer can change the control signal value of the electric motor by a command.

Alternatively, in addition to these, a collision is detected and added to the control signal of the electric motor.

[0008]

[Function] Generally, a path for orbiting is set by the power supply line and the traveling path, and the maximum speed depending on the driving skill of the driver,
The vehicle is instructed to start running after instructing the microcomputer to perform operational limits such as maximum acceleration, maximum deceleration, and minimum turning radius. The traveling speed, that is, the traveling speed of the driving electric motor is controlled according to the accelerator operation amount, and electric power is supplied from the outside to enable high speed traveling. Further, the turning radius is controlled according to the number of rotations of the steering electric motor and the rotation speeds of the left and right driving electric motors in accordance with the steering operation amount, and the turning can be performed with a small radius without slipping. Further, when a collision is detected, a control signal for turning in the avoidance direction or a decrease in traveling speed is sent to each electric motor.

[0009] Thus, the object of being able to be used both outdoors and indoors without causing environmental problems, and to make a complicated route on a small site to fully entertain people of various driving techniques is achieved. It
