The invention discloses an intelligent parking stall lock. The intelligent parking stall lock comprises a control circuit, a stop arm and a motor used for driving the stop arm to ascend or descend. The control circuit comprises a parking stall state sensor, a motor driving circuit, a current detecting circuit and a processing circuit, wherein the parking stall state sensor is used for detecting whether a shielding object exists above the intelligent parking stall lock or not and generating a parking stall state signal based on a detection result; the motor driving circuit is used for driving the motor to work; the current detecting circuit is used for detecting driving currents of the motor driving circuit; the processing circuit is used for determining the parking stall state based on the parking stall state signal and correcting the parking stall state based on the driving currents when the stop arm ascends. According to the intelligent parking stall lock, whether the stop arm collides with the shielding object or not is judged according to the driving currents for the motor, and then the parking stall state detected by the parking stall state sensor is corrected. In this way, the detection accuracy of the parking stall state can be greatly improved, which is beneficial for reducing the possibility of damaging a vehicle or the parking stall lock.
