A method for determining the sequence of vehicle tagged with and without an RFID, comprises: f1. carrying out multiple receiving and transmitting communications with an RFID tag in a read-write region by using an RFID reader-writer, recording success and failure operations; f2. setting a time window, moving the time window from left to right on a time axis, adding the success times of the receiving and transmitting communications to obtain a curve a; f3. detecting vehicles in the read-write region by using a ground induction coil to obtain a curve b; f4: when detecting a square wave in the curve b, indicating there is at least one vehicle driving through the coil, judging whether the driven through vehicle is installed with an RFID tag according to the wave time relationship between the curves a and b, judging whether there is a vehicle without an RFID tag among the vehicles with RFID tags driving through.
