Disclosed are an electric motor control system, a control method, and a vehicle. The electric motor control system (10) comprises a rear-stage DC/DC converter (12) of an on-board charger (OBC), a front-stage PFC (14) of the OBC, a first direct-current capacitor (18), a second direct-current capacitor (13), an electric motor inverter (17) and an open-winding electric motor (16), wherein two ends of the first direct-current capacitor (18) are connected to a high-voltage battery (11) and the electric motor inverter (17), respectively, so as to form a first channel, a direct current of the high-voltage battery (11) is inverted into a first three-phase alternating current by means of the first channel, and the open-winding electric motor (16) is driven by means of the first three-phase alternating current; and the high-voltage battery (11), the rear-stage DC/DC converter (12) of the OBC, the second direct-current capacitor (13), and the front-stage PFC (14) of the OBC are connected in a preset sequence, so as to form a second channel, the direct current of the high-voltage battery (11) is inverted into a second three-phase alternating current by means of the second channel, the open-winding electric motor (16) is driven by means of the second three-phase alternating current. Therefore, the problems of the function reuse degrees of an electric motor inverter (17) and an OBC being low, the error-tolerance rate of electric motor control being low, etc., are solved.
