Lane Indication Method for Navigation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems often cause driving errors and detours due to inadequate lane guidance, especially when intersections are close together, as users may not receive timely prompts for subsequent intersections, leading to reduced navigation success rates and safety concerns.
Innovation Solution
A method and apparatus that display lane prompt information for both the current and subsequent intersections within a designated range, allowing users to anticipate lane changes and reduce errors by providing simultaneous prompts on the navigation interface and through voice broadcasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation system provides only current intersection lane prompts, then the information displayed is simple and easy to process, but users may miss subsequent intersection prompts causing driving errors and detours
Solution Approach 1:
The patent applies preliminary action by displaying lane prompt information for subsequent intersections in advance before the vehicle reaches those intersections. The system determines the number of subsequent intersections based on the distance between intersections and the vehicle's speed, then displays their lane requirements ahead of time, allowing users to prepare for upcoming lane changes and avoid missing prompts at subsequent intersections.
2Reliability
If the navigation system displays lane prompt information for multiple subsequent intersections, then navigation accuracy and safety improve, but the information complexity and user cognitive load increase
Solution Approach 1:
The patent applies partial action by selectively displaying information for a specific number of subsequent intersections rather than all intersections. The system dynamically determines the number of subsequent intersections to display based on the distance between intersections and vehicle speed, showing only the necessary amount of information to ensure safety without overwhelming the user with excessive details.
Solution Approach 2:
The patent applies dynamics by making the number of displayed subsequent intersections adaptive rather than fixed. The system adjusts the information display dynamically based on real-time conditions such as vehicle speed and intersection spacing, increasing the number of prompts when speed is high or intersections are far apart, and reducing them when speed is low or intersections are closely spaced.

AI summary
A lane indication method includes: in response to a navigation start operation, displaying a navigation interface, where the navigation start operation indicates performing navigation based on a navigation start position and a navigation end position, and the navigation interface is configured to display a navigation route, the navigation route comprising at least one intersection; in response to being within a prompt range of a current intersection, providing lane prompt information corresponding to the current intersection and lane prompt information corresponding to a subsequent intersection of the current intersection.
