PURPOSE: A map matching method for a vehicle navigation system using Q-factor based on a study circuit network is provided to precisely carry out map matching for any roads by finding optimum parameter combination and easily adapting for changes of roads by using a study capability of the study circuit network. CONSTITUTION: In a map matching method for a vehicle navigation system using Q-factor based on a study circuit network, a map matching computation is carried out in such a manner that values D and V required for the computation of value Q are computed in a pre-computing part(30) by using a signal of which noise is removed in a navigation filter(10) and map information of a map information CD ROM(20), and existence of a travelling vehicle on a road is determined in a determination part(50), wherein a study circuit network(40) is provided between the pre-computation part and the determination part for studying a function having an output value αV+βD from the input values of the computed values D and V.
