However, in order to maintain the conventional electric vehicle system, it is necessary to perform maintenance of rails and overhead lines at regular intervals, and there is a problem that costs and labor are required. In order to solve this problem, there is a method of stopping the rails and making the wheels of rubber tires, but there is a problem that a lot of space is required to turn a curve in a train with a plurality of vehicles. In the case of rails, the angle of each wheel was forcibly changed, so the vehicle did not deviate from the rails and did not require much space to bend the curve. SUMMARY OF THE INVENTION An object of the present invention is to provide an electric vehicle control device that can be operated without overhead wires or rails.

  The above-described problems include an autonomous power source for generating electric power, a step-up / down chopper connected to the autonomous power source and controlling the output of the autonomous power source, and the step-up / down chopper connected to the step-up / down chopper. An inverter for conversion, a main motor driven by power supplied from the inverter, and an energy storage device capable of storing power when the main motor 6 performs a regenerative operation, and each vehicle, provided on each road surface A travel path detection device for detecting the position of the travel path guide, and a vehicle on which the vehicle is mounted so that the position of the travel path guide detected by the travel path detection device falls within a predetermined value. This can be achieved by providing a steering device.

According to the present invention, it is possible to provide an electric vehicle control device that can be operated without an overhead wire or a rail.

(First embodiment)
An electric vehicle control apparatus according to a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of an electric vehicle equipped with the electric vehicle control device according to the first embodiment of the present invention. FIG. 2 is a configuration diagram of the electric vehicle control device according to the first embodiment based on the present invention.

  The electric vehicle equipped with the electric vehicle control apparatus according to the first embodiment of the present invention is characterized in that it detects the travel path guide 9 and operates based on the position of the travel path guide 9.

  The electric vehicle control device according to the present invention is supplied from an autonomous power source 7 such as a fuel cell or a diesel generator, a step-up / down chopper 8 that controls the output voltage of the autonomous power source 7 and the output voltage of the energy storage device 22, and the autonomous power source 7. The energy storage device 22 that stores the generated electric power and is responsible for supplying energy to the load, the inverter 5 that controls the main motor, the main motor 6, and the road guide 9 (magnetic material) that is mounted on each vehicle is detected. The travel path detection device 10, the inverter 5, the brake control device 12, and the control device 11 that controls the wheels 4 are configured based on the position information of the travel path guide 9 input from the travel path detection device 10.

  In the electric vehicle control apparatus configured as described above, the travel path detection device 10 is coupled to a ground travel path guide 9, for example, a metal guide in a magnetic non-contact manner, and detects its position. However, since a method of detecting the position according to the contact state with the guide is also conceivable, it is not limited to the non-contact type. The control device 11 controls the brake command to the brake control device 12 of the host vehicle, the output command of the inverter 5, and the wheel 4 so that the position of the travel route guide 9 detected by the travel route detection device 10 is within a predetermined value. Calculates and outputs an angle command. Each vehicle can operate based on the position of the travel path guide 9. Therefore, the electric vehicle organization does not swell greatly. The electric power generated by the autonomous power source 7 is supplied to the energy storage device 22 and the step-up / down chopper 8. The energy storage device 22 stores the electric power supplied from the autonomous power source 7 and discharges according to the command of the inverter 5. The step-up / down chopper 8 converts the power generated by the autonomous power source 7 into a voltage and supplies it to the inverter 5. The inverter 5 converts the electric power supplied from the step-up / down chopper 8 and supplies it to the main motor 6. When the main motor 6 is performing a regenerative operation, regenerative power is supplied to the step-up / step-down chopper 8 via the inverter 5, and the voltage is stepped down and supplied to the energy storage device 22. The energy storage device 22 stores the electric power supplied from the step-up / step-down chopper 8. However, when the energy storage capacity of the energy storage device 22 exceeds a predetermined value, the inverter 5 is stopped and the vehicle is decelerated and stopped by the air brake.

  FIG. 3 shows a block diagram of an electric vehicle control device when a fuel cell is mounted as an autonomous power source 7 and EDLC is mounted as an energy storage device 22, and FIG. 4 shows a diesel generator mounted as an autonomous power source 7, and EDLC. The block diagram of the electric vehicle control device which installed the as an energy storage device is shown. When the fuel cell is mounted as the autonomous power source 7, it is necessary to boost the output voltage of the fuel cell and the EDLC. Therefore, the boost chopper 8 is provided between the fuel cell and the EDLC and the inverter 5. With this configuration, the power output from the fuel cell and EDLC can be used efficiently. When the diesel generator is mounted as the autonomous power source 7, the diesel generator can output a high voltage, and therefore a boost chopper 8 is provided between the EDLC and the inverter 5. By comprising in this way, an electric vehicle can be controlled efficiently like the electric vehicle control apparatus described in FIG.

  The electric vehicle control device configured as described above generates electric power by the autonomous power source 7, and the electric vehicle is driven by the generated electric power. In addition, each drive device (brake control device, inverter, wheel, etc.) provided in each vehicle operates based on information from the travel path detection device (magnetic sensor) that detects the travel path detection device 10 (magnetic material). Therefore, it is possible to prevent the phenomenon that the electric vehicle organization is bent off the traveling path.
