Problems solved by technology

[0006] For example, if there are multiple intersections between the current location and the navigation point, when the broadcast point broadcasts "Turn right ahead N meters", the user will often ignore the distance prompt of N meters and focus on turning right. It is possible to turn right at the nearest intersection immediately. At the same time, it is difficult for the user to make an accurate judgment on the distance during driving. If the user does not look at the navigation interface or does not have a navigation interface but only judges based on the broadcast distance, it is difficult to determine the end result. Go to that intersection to meet the broadcast distance and turn, so that the navigation may be inaccurate
At the same time, it is a burden for the user to allow the user to judge the driving distance, which reduces the satisfaction of the user's driving experience.

Embodiment 1

[0016] Such as figure 1 As shown, this embodiment provides a navigation method, including the following steps:

[0017] Step 11, calculating the navigation path, the navigation point and the navigation action of the navigation point.

[0018] Calculate whether every two Links on the navigation path need to be used as navigation points and navigation actions according to the position point of the Link (road section) and the attributes of the Link. The Link refers to a component of the navigation path. The path is composed of many Links. There is no fork in the road, and two roads with an out-degree or in-degree greater than 1 in the map cannot be merged into a Link. The out-degree refers to all the roads that a road can enter through the intersection at the fork. The in-degree refers to all the roads that can enter the current road through the intersection at the fork. Each Link is composed of a series of location points, and each location point is composed of longitude X an...

Embodiment 2

[0039] Such as image 3As shown, this embodiment discloses a navigation device, including: a determination unit, used to determine the number of confusing intersections between the initial navigation broadcast position and the navigation point; The starting navigation broadcast position adopts intersection counting mode to broadcast navigation information; the first making unit is used to make the first navigation action at the first predetermined distance from the confusing intersection, so as to prevent the vehicle from entering the wrong intersection; the second making unit uses A second navigation action is performed at a second predetermined distance from the navigation point to guide the vehicle into the intersection where the navigation point is located.

[0040] Before starting the determination unit, the device further includes: a calculation unit, configured to calculate a navigation path, a navigation point, and a navigation action of the navigation point.

Abstract

The embodiment of the invention provides a navigation method and device, which can improve the accuracy for reporting information and improve the satisfaction degree of driving experience of users. The method comprises the following steps of: determining the number of obscure intersections between the start navigation reporting position and a navigation point; reporting the navigation information on the start navigation reporting position according to the number of the obscure intersections in an intersection counting manner; making a first navigation at the first determined distance away from the obscure intersection to prevent vehicles from entering the intersection by mistake; and making a second navigation at the second predetermined distance away from the navigation point to guide vehicles entering the intersection where the navigation point locates. According to the embodiment of the invention, by reporting the navigation information on the start navigation reporting position in an intersection counting manner, users cannot turn in a wrong intersection by judging the distance by mistake, thereby inaccurate navigation is avoided and the satisfaction degree of the driving experience of the users is improved.

Description

technical field [0001] The present invention relates to a navigation technology, in particular to a navigation method and device. Background technique [0002] Existing navigation systems are generally composed of a location positioning module, a navigation guidance module, and a path planning module. Each module cooperates with each other to provide users with map-based location services. That is, the navigation system will make a navigation action before each navigation point. The navigation point refers to some points in the path that need to remind the user how to drive, such as turning, branching, switching roads or changing lanes. Generally, going straight is not used as a navigation point. The navigation action refers to the information that the vehicle prompts the user on how to drive when approaching the navigation point, such as broadcasting information "turn right 500 meters ahead". [0003] The main function of the navigation guidance module is: after the user ...
