Problems solved by technology
[0007] However, the method of displaying alternative routes to the user used by prior art personal navigation devices imposes a considerable burden on the processor just to generate maps of different alternative routes for the user.
Furthermore, it is quite difficult and dangerous for the user to simultaneously study each map representing different alternative routes while driving
This makes it difficult for the user to decide which route to choose among the known alternative routes in a fast and safe manner
What's more, the above method, in order to present the information provided to the user in an easy-to-understand manner, instead results in the provision of invalid information to the user
For example, information such as "suggest a detour route of X kilometers to save Y minutes" cannot really effectively help users choose a better alternative route to save time, causing inconvenience to users
[0008] It can be seen that the above-mentioned existing personal navigation device used to display alternative routes to the user obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

The invention relates to an individual navigation device presenting alternate routes and a navigation method. The method comprises the following steps of: providing a navigation indication for guiding a user to be in an original route selected by the user; receiving and analyzing dynamic traffic information; determining the existence of a first alternate route according to the dynamic traffic information, wherein the first alternate route has shorter traveling time compared with the original route potentially; and promoting the user whether to select to advance along the first alternate route, wherein the first alternate route is described as at least one street name relevant to the first alternate route.
Description
technical field [0001] The present invention relates to a personal navigation device, and more particularly to a method of using street names on a personal navigation device to inform a user of an alternative route to inform the user about an optional detour route. Background technique [0002] A navigation device based on a Global Positioning System (GPS) is a well-known device widely used in vehicles to provide navigation information for drivers. A general navigation device has functions including providing a map database for displaying navigation instructions on a display of the navigation device. The navigation device is usually arranged on or in the instrument panel of the vehicle by adsorption or other erection methods. [0003] The term "navigation device" refers to a device capable of providing user navigation information so that the user can reach a predetermined location. The navigation device may contain an internal system (such as a GPS receiver) for receiving ...
