The invention provides a control circuit for a full-automatic automobile sunshade. The control circuit comprises a command receiving circuit used for receiving an external control signal, processing the signal and feeding back the signal to a micro processor. The control circuit also comprises a power supply circuit, a voltage detecting circuit, an unfolding limiting switch, a tightening limiting switch, a first motor, a second motor, a first motor driving circuit and a second motor driving circuit. The control circuit for a full-automatic automobile sunshade has a compact structure; by arranging the micro processor and other circuit components, the unfolding and tightening of the sunshade can be automatically achieved; the labor intensity is greatly lowered; meanwhile, it is convenient to use, and the circuit system is reliable and durable.
