Problems solved by technology

[0003] Although the existing navigation devices have many functions and all have the function of voice broadcast, which can realize voice navigation for complex intersections, they do not have reminders of variable lanes, and the route planning during peak hours does not have the function of avoiding variable lanes that are easy to congest.
Therefore, when the driver is going to pass through the variable lane, it is completely impossible to obtain any help from the existing navigation device.

Embodiment Construction

[0017] figure 1 Shown is a flow chart of the steps of a preferred embodiment of the navigation method for variable lane indication reminders in the present invention. The navigation method for variable lane indication reminders in the present invention includes the following steps:

[0018] Step 100: path planning;

[0019] In this embodiment, during the route planning process using a navigation device based on the starting and ending points, a variable lane avoidance switch during peak hours is provided. , and estimate the time point when driving to the variable lane that is passing through at present, calculate the number and level of the lane at that time, plan whether to pass through the variable lane, and present a navigation path that avoids the variable lane during peak hours, so as to avoid the peak During the road section with a small number of lanes, if the switch is turned off, the navigation device presents a navigation path that does not avoid variable lanes duri...

Abstract

The invention discloses a navigation method capable of indicating and prompting variable lanes, which is characterized by comprising the following steps: planning a route; according to the current period, detecting whether a variable lane is existed at front or not, displaying the information of the variable lane at front; prompting the attention for driving to the correct lane to the user by voice broadcast; and prompting the current lane direction at front by the voice broadcast. By the above navigation method, a driver can smoothly pass through the variable lane, so that unnecessary trouble can be avoided.

Description

【Technical field】 [0001] The invention relates to a navigation device, in particular to a navigation device with a variable lane indication reminding function. 【Background technique】 [0002] With the improvement of people's living standards, more and more families have their own private cars, but the roads are becoming more and more congested. In order to solve the traffic flow at intersections with serious tidal phenomena, variable lanes gradually appear in major traffic intersections. The variable lane will change the number of lanes or the driving direction according to the traffic conditions of the road at different times. In the case of a change, if the driver does not get the advance warning information, it is too late to change lanes and block the road, which will cause unnecessary trouble. [0003] Although the existing navigation devices have many functions and all have the function of voice broadcast to realize voice navigation for complex intersections, they do...
