The invention relates to the technical field of unmanned vehicles, in particular to an automatic vehicle door control method. The automatic vehicle door control method is applied to an unmanned vehicle. The unmanned vehicle comprises a navigation module, a control center, a traffic light identification module, an obstacle detection module, a fault monitoring module and a brake module. The method comprises the steps as follows: S1: the control center receives an abnormal signal and performs judgment; S2: whether the abnormal signal is a trouble signal causing the condition that the vehicle cannot travel is judged, and if the abnormal signal is not the trouble signal, S3 is implemented; S3: whether the abnormal signal is a signal for indicating that the vehicle arrives at a designated parking space is judged, and if the abnormal signal is not the signal for indicating that the vehicle arrives at the designated parking space, S4 is implemented; S4: whether the abnormal signal is an obstacle signal is judged, and if the abnormal signal is not the obstacle signal, S5 is implemented; S5: the process returns to S1. With the method, a vehicle door can be controlled effectively according tothe state of the unmanned vehicle.
