Abstract
A vehicle position detecting method comprises: continuously detecting a detection region and generating a sensing signal by a sensor (S100); continuously determining whether a sudden change exists in the sensing signal, and starting timing when the sensing signal suddenly changes (S200); terminating timing after a preset time, if the sensing signal received at an end of timing does not restore to the sensing signal prior to the sudden change, confirming a vehicle is or is not in the detection region (S300); the sudden change is defined as a variation of the sensing signal per unit time exceeding a preset range. A vehicle position detecting system is also provided.
