The invention discloses a linkage control system, and particularly relates to an automobile door lock linkage starting system. The linkage starting system detects whether an automobile door is closed completely or not by arranging a sliding rod and a pressure sensor on a door frame. If the automobile door is not closed completely, the automobile door cannot be completely attached to the inner side face of the door frame, and the sliding rod cannot be completely pressed into the door frame. The stretching length of the sliding rod is detected through a sensing mechanism, only when the sliding rod completely stretches into the door frame, can a whole automobile controller receive a corresponding triggering signal or a triggering signal meeting the preset strength requirement, and then the whole automobile controller can trigger a main motor ECU and a power motor to be started. The technical defect that in the prior art, an automobile can be started before the automobile door is not closed is overcome, and the automobile door lock linkage starting system can prevent the automobile from being started in the state that the automobile door is not closed completely.
