Navigation system, navigation method, and navigation terminal for escaping from current position

A navigation system, a navigation method, and a navigation terminal for escaping from a current position are provided. The navigation system comprises a vehicle-mounted navigation terminal and a service center. The vehicle-mounted navigation terminal comprises a processing module, a human-machine interactive module, a GPS module for providing the current position information, a first communication module for communicating with the service center, and a memory module for providing digital maps; wherein the human-machine interactive module, the GPS module, the first communication module, and the memory module are individually connected to the processing module, and the human-machine interactive module is provided with a button for representing a function of triggering an escaping function. When a user needs to escape from a current position, he just needs to trigger the escape button, the vehicle-mounted terminal takes the current position information from the GPS module as the address where the user needs to escape and sends the ID information of the vehicle-mounted navigation terminal to the service center; the service center collects and processes the dynamic traffic data of the escape position, then generates an escape route, and sends the escape route to the navigation terminal; and the user's vehicle-mounted navigation terminal escapes from the current position according to the provided escape route, and thus the travel efficiency is improved.
