Abstract

The invention discloses a navigation system and a method for planning a route thereof. The navigation system includes a storage unit and a processing unit. A cloud database of a cloud server and a local database of the navigation system are allocated in the storage unit, which is configured to store road condition data. The processing unit is connected to the storage unit, and generates an initial route according to an initial location and a destination. The processing unit also compares, computes and analyses the initial route and the road condition data, corresponding to at least one road section of the initial route, stored in the storage unit to generated a plurality of reference routes. Next, one of the reference routes is selected as a final route.

Description

technical field [0001] The present invention relates to a navigation system and a path planning method thereof, in particular to a navigation system utilizing a cloud database data sharing mechanism and a path planning method thereof. Background technique [0002] With the popularization of mobile devices and the development of wireless network applications, various mobile devices continue to increase navigation functions related to Global Positioning System (Global Positioning System, GPS) or satellite positioning, such as smart phones (Smart Phone), Personal digital assistant (Personal Digital Assistant, PDA) or tablet computer (Tablet PC), etc., to facilitate users to grasp the real-time activity path or peripheral information of the activity range at any time. However, when a user uses a mobile device to use the navigation function, problems often occur that the route planned by the navigation system cannot be followed. The routes provided by the navigation system do no...
