A return method and navigation device

Abstract

The embodiment of the invention discloses a course reversal method and navigation equipment. The course reversal method comprises the following steps of judging whether the value of the distance between an initial positioning site and a starting point of the latest navigation path is greater than a first preset value or not, and if so, setting the initial positioning site to be a course reversal destination, and performing navigation according to the course reversal destination and a course reversal starting point. According to the method and the equipment, the course reversal destination can be corrected to help a user conveniently return to the course reversal destination in which the user really wants to arrive and improve the course reversal efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the field of navigation, and in particular, to a return method and a navigation device. Background technique [0002] Navigation equipment refers to equipment with various functions related to location, such as navigation or positioning, such as portable navigators, car navigators, tablet computers, computers or mobile phones. Its working principle is that the navigation device determines the position coordinates of a specific location, and matches them with the position coordinates recorded in the electronic map stored by itself, so as to determine the exact position of the navigation object equipped with the navigation device in the electronic map. There is a memory in the navigation device to store data such as electronic maps, address books, and personal favorites. Navigation objects can be vehicles, pedestrians, etc. After the user sets the starting point and the destination, the navigation devi...

Problems solved by technology

[0003] The return service provided by the existing navigation equipment is generally specifically to simply exchange the destination used by the user for the last navigation and the departure place, that is, set the destination as the return departure place, set the departure place as the return destination, and reset the destination to the return destination. Plan the navigation path between the new destination and the departure place for navigation. If the user navigates multiple times during the use of the navigation device and then uses the return function, it may cause that the return flight cannot return to the departure place that the user really wants to return to.
