An improved central lock control system adapted for automatically locking and unlocking all the four doors by way of operation on the lock knobs mounted on the two front doors, and only permitting to automatically unlock all the four doors by way of operation on the lock knobs mounted on the two rear doors for safety consideration; the present lock control system is characterized in that the motor, used to control the motion of an actuator which enables the lock knobs of the doors to perform the locking and unlocking operation, is able to spin clockwise or counter clockwise to generate an inductive voltage on the lock knob being pulled up to unlock or pushed down to lock the doors; the generated inductive voltage is input into an electronic module for logic comparison so to effect the above cited control operation; whereby the control circuit is simplified to a large extent and the mounting of the present system is made easy; besides, the production cost is effectively lowered as a result of the removal of a signal switch.
