Autonomous Drive Lane Display With Remaining Lane Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective systems to identify and display pre-approved lanes for autonomous driving modes, leading to inefficiencies and potential safety risks due to the need for continuous operator input or reliance on detailed maps.
Innovation Solution
A system that uses a processor to receive geographic data, identify autodrive lanes from detailed maps, and generate display information indicating available lanes for autonomous driving, including indicators for current location, remaining distance, and lane availability, using color coding and icons to differentiate between usable and non-usable lanes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If autonomous vehicles rely on highly-detailed maps to make driving decisions, then driving accuracy is improved, but system complexity increases
Solution Approach 1:
The patent extracts and highlights only the critical information needed for autonomous driving - specifically autodrive lanes - from highly-detailed maps. By displaying only the relevant lane information rather than all map details, the system maintains driving accuracy while reducing the complexity of information processing and presentation to the operator.
2Loss of information
If the system provides comprehensive lane information, then operator awareness is improved, but information overload occurs
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of different lane types. Autodrive lanes are highlighted with distinct visual properties (such as special coloring or icons) compared to regular lanes, allowing operators to quickly identify approved autonomous driving lanes without being overwhelmed by unnecessary detail about all lanes.
Solution Approach 2:
The patent segments lane information into distinct categories - autodrive lanes versus regular lanes - and presents them differently on the display. This segmentation allows the operator to focus on the critical subset of lanes approved for autonomous operation while still having access to complete lane information if needed.
3Ease of operation
If the vehicle operates in autonomous driving mode without lane identification, then operator workload is reduced, but safety risks increase
Solution Approach 1:
The patent implements feedback by providing the operator with visual information about which lanes are approved for autonomous driving. This feedback mechanism allows the operator to monitor the system's autonomous operation and intervene if the vehicle attempts to use non-approved lanes, thereby maintaining safety while reducing routine operator workload.

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.
