The invention provides a drive disengagement method and mechanism and an automobile. The drive disengagement method comprises the steps that a torque demand is obtained; determining a target position of the disengagement mechanism based on the torque demand; the position of a synchronizer connected with an intermediate shaft is obtained, and the synchronizer is connected with a driving motor and the disengaging mechanism; the current rotating angle of a disengaging motor providing power for the disengaging mechanism is obtained; based on the position of the synchronizer and the current rotating angle of the disengaging motor, the current position of the disengaging mechanism is determined; based on the current position and the target position of the disengaging mechanism, the disengaging motor is made to rotate; and adjusting the disengaging mechanism from the current position to the target position according to the rotating speed and the torque output by the disengaging motor. The four-wheel-drive and two-wheel-drive dynamic conversion of the vehicle can be achieved in different driving modes, different working conditions and different environments, the four-wheel-drive dynamic property can be achieved, and the real-time four-wheel-drive economical efficiency can also be achieved.
