The invention provides a disengaging mechanism control method and system and a vehicle, and relates to the technical field of vehicles. The disengaging mechanism control method comprises the steps that a wheel end rotating speed signal, a driver torque demand signal, a vehicle state signal and a motor rotating speed signal are obtained; according to the wheel end rotating speed signal and the motor rotating speed signal, the current state of the disengaging mechanism is determined; the target state of the disengaging mechanism is determined according to the driver torque demand signal, the vehicle state signal and the current state of the disengaging mechanism, and the sequential control state of the disengaging mechanism is determined according to the target state of the disengaging mechanism; and performing motor arbitration according to the time sequence control state, and controlling the running state of the driving motor according to a motor arbitration result. Separation and combination of the disengagement mechanism can be achieved without a position sensor, and the control cost of the disengagement mechanism can be reduced; motor control and disengaging mechanism control can be achieved at the same time, and the system integration degree can be improved.
