Self-Driving Navigation Handover Prompts for Missed Turn Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing vehicle navigation systems, when switching from a self-driving state to a manual driving state, vehicles often miss critical intersections and travel on incorrect routes due to insufficient information from the guidance panel, leading to poor guidance performance and hardware resource underutilization.
Innovation Solution
A method and apparatus that display an assisted driving interface with self-driving information and output takeover prompt information when approaching a state switching point, followed by displaying a navigation map to ensure accurate route navigation upon switching to manual driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle displays only a guidance panel during self-driving state, then the hardware display resources are saved, but the navigation information is insufficient causing the vehicle to miss critical intersections
Solution Approach 1:
The navigation map is displayed in advance before the vehicle reaches the state switching point. This preliminary display ensures that the driver has sufficient navigation information available before transitioning from self-driving to manual driving mode, preventing missed intersections and route errors.
Solution Approach 2:
The display system dynamically adjusts its output based on the vehicle's driving state and proximity to state switching points. During normal self-driving, only essential guidance panel information is shown. However, when approaching a state switching point, the system automatically displays the full navigation map to ensure complete information availability.
2Reliability
If the navigation map is displayed continuously, then the navigation information is complete, but the hardware display resources are underutilized during self-driving state
Solution Approach 1:
The navigation map is displayed in advance before the vehicle reaches the state switching point. This preliminary display ensures that the driver has sufficient navigation information available before transitioning from self-driving to manual driving mode, preventing missed intersections and route errors.
Solution Approach 2:
Instead of continuous display, the navigation map is displayed periodically or conditionally - specifically when the vehicle approaches a state switching point. This periodic display approach maintains high reliability when needed while optimizing display resource utilization during normal self-driving operations.
3Ease of operation
If the vehicle switches from self-driving to manual driving without advance notice, then the automation transition is smooth, but the driver cannot prepare for takeover leading to incorrect routing
Solution Approach 1:
The navigation map is displayed in advance before the vehicle reaches the state switching point. This preliminary display ensures that the driver has sufficient navigation information available before transitioning from self-driving to manual driving mode, preventing missed intersections and route errors.
Solution Approach 2:
The system provides feedback to the driver about the upcoming state switching by displaying the navigation map in advance. This feedback mechanism allows the driver to prepare for the transition and understand the current route context, ensuring smooth automation transition while maintaining information availability.
Data Source
AI summary
A vehicle navigation method includes displaying an assisted driving interface including self-driving information of a vehicle in response to the vehicle being in a self-driving state, and in response to a distance between a location of the vehicle and a state switching point being shorter than a distance threshold, outputting takeover prompt information based on the assisted driving interface. The state switching point is a location on a road at which the vehicle is automatically switched from the self-driving state to a manual driving state. The method further includes displaying a navigation map in response to the vehicle being switched from the self-driving state to the manual driving state.
