Embodiment Construction

[0025] According to the navigation steering action information at the intersection and the allowed steering action information of each lane, the navigation device in the embodiment of the present invention determines the lane that the user should change to in each lane of the current road section, and provides the identification information of the determined lane to the user , so that the user can change to the correct lane in time according to the information, avoiding detours and illegal lane changes, which can effectively reduce the risk of traffic accidents.

[0026] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 2 The navigation process provided for the embodiment of the present invention specifically includes the following steps:

[0028] S201: Among the road sections included in the navigation route, determine the road section where the user is currently located as the current road ...

Abstract

The invention discloses a navigation method and device for solving the problems that a user takes a roundabout way or the risk of traffic accidents is increased because of navigation information provided by navigation device in the prior art. The method comprises the steps of determining the current road segment from road segments included in a navigation route, determining navigation steering action information at an intersection of the current road segment, determining a lane steering action permission information of which is matched with the navigation steering action information from lanes included by the current road segment, and offering the identification information of the determined lane to the user. According to the method, the navigation device can offer the information of the lane to be arrived for the user, the user can immediately change to a right lane according to the information for avoiding conditions of taking a detour and changing the lane illegally, and the risk of the traffic accidents is effectively reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a navigation method and device. Background technique [0002] At present, the application of navigation devices has been very common. The navigation device can provide the user with navigation route information from the origin to the destination according to the input origin and destination. [0003] Usually, a navigation route includes several road sections and several crossings. When the user is about to drive to a certain crossing, the navigation device can prompt the user to navigate and turn at the crossing by playing navigation guidance information. For example, when the user is 100 meters away from the next intersection, the user is prompted to "turn left at the intersection ahead". [0004] However, a road section often includes multiple lanes, and the allowable turning actions of these multiple lanes at intersections are not exactly the same, such as fi...
