駕駛者開車出門若是匆匆忙忙前往目的地或是停車場過於龐大，導致駕駛者忘記自己停放的 停車格在哪一區，必須浪費許多時間尋找愛車，甚至可能因此多負擔停車費。目前已有許多智慧 手持裝置應用程式可協助駕駛者尋找愛車，但其無法在接收不到衛星定位經緯度資訊環境使用。 此篇研究論文整合航位推算技術及車速資訊進行移動軌跡運算，車輛進入接收不到衛星定位經緯 度資訊環境下亦可計算出所停放位置，提供給駕駛者更有效率搜尋愛車之智慧型尋車系統。

It is a big trouble for drivers while they forget their parking position of vehicle. At present, there are many smart handheld devices application developed to help drivers search their vehicles. However, the current method does not work in the area failing to receive satellite signals. In this paper, we apply dead reckoning technology and use vehicle speed and heading information to calculate the movement trajectory. The proposed method is also workable when vehicle enters area without satellite positioning signal. The latitude and longitude of the parked positions calculated make drivers more convenient to search their vehicles.
