Autonomous Driving Lane Display With Remaining Distance Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective systems to identify and display available lanes for autonomous driving modes, leading to inefficiencies and potential safety risks due to unclear lane availability during transitions between manual and autonomous driving.
Innovation Solution
A system that utilizes a processor to receive geographic data, identify autodrive lanes from detailed maps, and generate display information indicating available lanes, current location, and remaining distance for autonomous driving, using color coding and icons to differentiate between usable and non-usable lanes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system provides detailed lane information for autonomous driving, then driver awareness and safety are improved, but the device complexity and information processing requirements increase
Solution Approach 1:
The system segments lane information into distinct categories (autonomous driving lanes vs. non-autonomous lanes) and presents them separately on the display. This segmentation allows the complex information to be organized in a manageable way, improving driver awareness without overwhelming the system with unstructured complexity.
Solution Approach 2:
The system pre-identifies and marks autonomous driving lanes in advance using map data before the vehicle reaches them. This preliminary action allows the system to prepare lane information ahead of time, reducing real-time processing complexity while ensuring accurate driver awareness when needed.
2Loss of information
If the system displays multiple lane options with remaining distances, then the information completeness is improved, but the ease of operation and driver decision-making speed may deteriorate
Solution Approach 1:
The system applies different visual qualities to different lanes based on their autonomous driving status. Autonomous driving lanes are highlighted with specific visual indicators (such as different colors or icons) while non-autonomous lanes are displayed differently. This local quality differentiation helps drivers quickly identify suitable lanes without being overwhelmed by uniform detailed information about all lanes.
Solution Approach 2:
The system uses color coding to differentiate between autonomous driving lanes and non-autonomous lanes. This visual distinction allows drivers to rapidly comprehend lane availability and make decisions based on color cues rather than analyzing text or numerical data for each lane, thus maintaining information completeness while improving ease of operation.
3Reliability
If the system continuously updates lane availability information, then the reliability and current accuracy are improved, but the energy consumption and processing load increase
Solution Approach 1:
The system updates lane availability information periodically based on vehicle position changes or predetermined intervals rather than continuously. This periodic action maintains reliable and current lane information accuracy while significantly reducing the energy consumption and processing load associated with constant real-time updates.
Solution Approach 2:
The system uses pre-stored map data containing autonomous driving lane information to self-update lane availability based on the vehicle's current location. This self-service approach allows the system to maintain accurate lane information without requiring continuous external data streams or intensive real-time processing, thereby reducing energy consumption while preserving reliability.

AI summary
Aspects of the present disclosure relate generally to identifying and displaying traffic lanes that are available for autonomous driving. This information may be displayed to a driver of a vehicle having an autonomous driving mode, in order to inform the driver of where he or she can use the autonomous driving mode. In one example, the display may visually distinguishing between lanes that are available for auto-drive from those that are not. The display may also include an indicator of the position of a lane (autodrive or not) currently occupied by the vehicle. In addition, if that lane is an autodrive lane the display may include information indicating how much further the vehicle may continue in the autonomous driving mode in that particular lane. The display may also display information indicating the remaining autodrive distance in other lanes as well as the lane with the greatest remaining autodrive distance.
