Embodiment Construction

[0040] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0041] see figure 1 , the present invention provides a navigation method for existing problems, including:

[0042] Step 101, obtaining the starting point and ending point of the current user, and generating a planned path according to the starting point and ending point;

[0043] Here, firstly, a planned route is generated according to the starting point and end point of the user; the planned route is based on roads.

[0044] Further, before step 101, the method also includes:

[0045] The lane parameters of each lane are obtained, and the lane parameters at least include: lane direction, lane type, lane width limit, lane height limit, and turning arrow.

[0046] Further, the lane types at least include: regular lanes, acceleration lanes, deceleratio...

Abstract

The invention provides a navigation method and device. The method comprises the following steps: obtaining the present start point and terminal point of a user, according to the start point and terminal point, generating a planned route; obtaining the parameters of a present vehicle of the user and the parameters of each lane in the planned route, determining the drivable lanes for the user; determining the lane changing points on the drivable lanes, wherein the lane changing points at least comprise front lane number changing points and branch points of intersections; in each lane changing point before the terminal point, generating an optimal route from a current lane to a front lane, and showing each optimal lane to the user. The route guiding reaches the lane level, more real and safer information is provided for a user; moreover, in the intersection, detailed lane guiding information is provided, thus a user can rapidly and safely pass the intersection; due to precise lane data, more safety guarantees are provided for a user, and the accidents are reduced.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a navigation method and device. Background technique [0002] With the development of life, navigation has become an important part of people's travel, which brings great convenience to people's travel. However, the existing navigation is mostly based on the guidance between roads, and the path planning can only be accurate to the road, not to the specific lane; and there is no detailed traffic information at the intersection and the traffic information between the lanes. Under the circumstances, the maximum convenience cannot be provided to the user. Contents of the invention [0003] The present invention provides a navigation method and device, aiming to solve the problem that the existing road-based navigation cannot be accurate to specific lanes, and there is no detailed traffic information at intersections and traffic information between lanes. [0004] In order to achieve the...
