Zusammenfassung:According to the technical scheme, in response to the control instruction for the electric phaser mechanism, the rotating speed of the air inlet cam shaft mechanically connected with the motor of the electric phaser mechanism is obtained. And the target rotating speed of the motor is determined through the rotating speed of the air inlet cam shaft. Acquiring state information uploaded by the electric phaser mechanism, wherein the state information comprises the current rotating speed and the current rotating direction of the motor; and comparing the target rotating speed and the current rotating speed of the motor as well as the target rotating direction and the current rotating direction to obtain a first difference value and a second difference value, and verifying the state information based on the first difference value and the second difference value to obtain a verification result, so that the motor is controlled based on the verification result, and the phenomenon of motor overcurrent caused by wrong s
