The invention discloses an automatic calibrating system for elevator car stopping. The automatic calibrating system comprises a car detection circuit, a hall door control circuit, a first laser emitter, a first laser receiver, a second laser emitter and a second laser receiver, wherein when the movement of a car is detected, triggering signals are formed; the hall door control circuit obtains the data of a floor where the car need to reach according to the triggering signals and generates signals used for controlling the first laser emitter and the second laser emitter on the floor; the first and second laser emitters produce laser beams, and the first and second laser receivers receive the laser beams; the first laser receiver and the second laser receiver respectively generate feedback signals according to the received laser beams and send the feedback signals to the hall door control circuit; the hall door control circuit controls an elevator hall door to be opened when receiving the two feedback signals. The automatic calibrating system ensures that the hall door is opened only when the car is stopped, effectively prevents personnel from missing step and falling, and improves the operation safety.
