Zusammenfassung:	The invention relates to a self-powered wheel rotating speed intelligent display method which comprises the following steps that a power generation motor circuit is connected with a target automobile wheel in advance, the power generation motor circuit is used for generating three-phase alternating current when the wheel rotates and converting the three-phase alternating current into direct-current voltage, and the direct-current voltage is used for supplying power to an MCU; the DC voltage is obtained every preset period; and converting the direct-current voltage through a pre-established mathematical model of the rotating speed of the motor and the output voltage of the motor to obtain the rotating speed of the power generation motor. An external power supply is not needed, the circuit structure is simple, the wheels are used for driving the power generation motor to generate power and provide power, the microcontroller is used for collecting the voltage value of the power generation motor, the rotating spe
