Embodiment 1

[0061] see figure 1 , which is a flowchart of a navigation method provided in this embodiment, the method includes:

[0062] Step 101: The external device installed in the vehicle acquires navigation guidance information from the smart terminal.

[0063] Wherein, the smart terminal can be a smart device such as a mobile phone, and the smart terminal can provide navigation guidance information for the user. The navigation guidance information is the navigation information provided by the smart terminal to the user. The user can drive to the destination according to the navigation guidance information. The navigation guidance information includes the driving direction. When the navigation information is a left turn at the intersection ahead, the driving direction is a left turn , when the navigation guidance information is going straight at the intersection ahead, the driving direction is going straight, and when the navigation guidance information is turning left at the inters...

Abstract

The invention discloses a navigation method and an external device for navigation. The external device arranged in a vehicle and an intelligent terminal are in data connection; in the navigation process of the intelligent terminal, the intelligent terminal can send navigation guide information comprising driving direction to the external device; the external device judges whether the driving direction of the vehicle is consistent with the driving direction in the navigation guide information; and if not, it is judged that the vehicle may not be driving in accordance with the navigation guide information, or the driving direction has not been changed to be consistent with the driving direction in the navigation guide information; and therefore, a guidance prompt corresponding to the drivingdirection in the navigation guide information can be made through the externally device to further remind users how to drive the vehicle based on navigation, and navigation experience of users is improved.

Description

technical field [0001] The present application relates to the field of electronic navigation, in particular to a navigation method, an external device and a system. Background technique [0002] Movable smart terminals such as mobile phones can provide users with electronic navigation services. When users take vehicles, they often use smart terminals for navigation. [0003] When the user uses the smart terminal to navigate in the vehicle, due to some reasons, the user may miss the navigation guidance information given by the smart terminal, and may turn at the wrong intersection, or drive past the intersection that should be turned. [0004] It can be seen that it is not enough to simply rely on the navigation guidance information provided by the smart terminal for navigation. If the navigation guidance information of the smart terminal is missed, the user's navigation experience will be reduced. Contents of the invention [0005] In order to solve the above-mentioned te...
