    According to the embodiment of the present invention, in the calculation comparison step, the predetermined temperature value is in the range of 57 ° C. to 65 ° C., and 59 ° C. is more preferable.

    According to the embodiment of the present invention, in the speed control step, the speed adjustment unit is connected to the power unit and the arithmetic processor.

    According to an embodiment of the present invention, in the speed control step, when the controller temperature is too high, the arithmetic processor drives the speed adjustment unit to reduce the current supplied to the motor by the power unit, Reduce motor speed when controller temperature is too high.

    According to the embodiment of the present invention, if it is calculated that the controller temperature is in the range of 55 ° C. to 72 ° C. in the calculation contrast step, the current supplied by the power unit to the motor in the speed control step Then, adjust to be able to travel up to 45km.

    According to the embodiment of the present invention, if it is calculated that the temperature of the controller is in the range of 65 ° C. to 82 ° C. in the calculation contrast step, the current supplied by the power unit to the motor in the speed control step. Then, adjust to be able to travel up to 33km.

    According to the embodiment of the present invention, if it is calculated that the controller temperature is 82 ° C. or higher in the calculation contrast step, the current supplied by the power unit to the motor in the speed control step is up to 8 km. Adjust so that you can run.

    Hereinafter, the features and technical contents of the present invention will be described in detail with reference to the drawings. However, the drawings and the like are for reference and explanation, and the present invention is not limited thereby.

It is a flow conceptual diagram of the present invention. It is a block conceptual diagram of the present invention.

    1 and 2 are a flow conceptual diagram of the present invention and a block conceptual diagram of the present invention, respectively. As shown in the figure, the present invention is a speed control method based on the temperature of an electric vehicle, and the electric vehicle operating device is connected to at least a controller 1, a motor 2 connected to the controller, and at least two motors 2. A power unit 4 connected to the wheel 3 and the controller 1 is contained, a temperature detection unit 5 is connected to the controller 1, an arithmetic processor 6 is connected to the temperature detection unit 5, and There is a speed adjustment unit 7 connected to the electric power unit 4 and the arithmetic processor 6, and the temperature speed control method of the electric vehicle includes at least the following steps.

    In the temperature detection (a) step, when the electric vehicle is operated, the temperature detection unit 5 continuously detects temperature data generated by the controller 1 of the electric vehicle during the operation process.

    In the calculation comparison (b) step, the temperature data is sent to the calculation processor 6, the temperature detection result of the temperature detection unit 5 is collected by the calculation processor 6, and compared with a predetermined value of the calculation processor 6, and the controller It is determined whether the operating temperature of 1 is too high, the predetermined temperature value is in the range of 57 ° C to 65 ° C, and 59 ° C is more preferable.

    In the speed control (c) step, when the temperature of the controller 1 of the electric vehicle is too high, the speed adjustment unit 7 is driven by the arithmetic processor 6 so that the current supplied to the motor 2 by the power unit 4 is reduced. If it is calculated in the calculation contrast (b) step that the temperature of the controller 1 is within the range of 55 ° C. to 72 ° C., the power unit 4 supplies the motor 2 with the speed adjustment unit 7 in this step. If the current is adjusted so that it can travel up to 45 km and the temperature of the controller 1 is calculated within the range of 65 ° C. to 82 ° C., in this step, the speed adjustment unit 7 If the current supplied to the motor 2 is adjusted so that it can travel up to 33 km, and if the temperature of the controller 1 is calculated to be 82 ° C. or higher, in this step the speed adjustment unit 7 The motor 4 adjusts the current supplied to the motor 2 so that it can travel up to 8 km. When the temperature detection unit 2 detects a decrease in the temperature of the controller 11, the traveling speed is adjusted according to the related set value.
