The invention discloses an asynchronous motor electric vehicle control device. The input end of a low-pass filtering circuit is connected with the negative electrode of a storage battery, the output end of the low-pass filtering circuit is connected with the input end of a DSP control chip, a voltage detection circuit is connected to the two ends of a filtering capacitor (C1) in parallel, a pre-charge resistor (R1) is connected to the two ends of a contactor (K2) in parallel, the two ends of an absorption capacitor (C2) are connected with the input end of an IPM, the output end of the IPM is connected with a motor, a photoelectric encoder is arranged on the motor, the output end of the photoelectric encoder is connected with the input end of the DSP control chip, and the photoelectric encoder comprises an optical grating disc, a photoelectric sensor and an LED. The aim of accurately controlling the rotating speed of the asynchronous motor is achieved.
