The invention discloses a control system of a movable hard top, comprising two network channels; one channel is a high speed CAN network channel composed of a bodywork control unit, a hard-top control unit and an instrumentation system; another channel is a LIN network channel mainly composed of the bodywork control unit and a supplementary instrument; the gateway of the buses of the CAN and the LIN is integrated in the bodywork control unit; the two network channels realize data exchange by the gateway. The communication of the CAN bus between the hard top control unit and the bodywork control unit adopts a request feedback priority level management method; an operation order is managed according to the priority level. In the invention, by means of the combination of the CAN bus and the LIN bus, the two buses are capable of having complementary advantages; by introducing the gateway, the network is divided into two networks under a relatively independent control, thereby strengthening the reliability and the
