Adaptive Lane Guidance Debounce Timing for Changing Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane-keeping assistants fail to efficiently remove elemental mercury (Hg0) from flue gas and oxidized mercury (Hg2+) from waste liquid, with activated carbon injection technology being costly and its mercury removal efficiency is affected by NOx and SO2.
Innovation Solution
Utilization of metal sulfides (e.g., FeS2, CuS, CuFeS2) as mercury removal adsorbents, which contact with flue gas and waste liquid, adsorbing and converting Hg0 from flue gas and Hg2+ from waste liquid into stable mercury sulfide compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed debounce time is used to ensure continuous availability of the lane guidance assistant, then reliability is improved, but availability is reduced because the function cannot be activated when conditions temporarily prevent meeting the debounce time
Solution Approach 1:
The debounce time is changed from a fixed value to a dynamic parameter that adapts based on environmental conditions. The system continuously monitors conditions such as lighting, weather, road surface, and lane marking visibility, and adjusts the debounce time accordingly. This allows the system to maintain reliability by requiring sufficient confirmation of lane boundaries while improving availability by reducing the debounce time when environmental conditions are favorable
Solution Approach 2:
The system changes the parameter of debounce time based on multiple environmental factors. Different base values are selected depending on lighting conditions (day/night), weather conditions (rain/snow/fog), road surface conditions (wet/dry/icy), and lane marking visibility. This parameter adaptation resolves the contradiction by allowing the system to be more lenient when conditions are good and more strict when conditions are poor
2Stability of the object's composition
If the debounce time is increased to avoid frequent state changes, then continuity of functional state is improved, but availability is reduced because activation is delayed
Solution Approach 1:
The system dynamically adjusts the debounce time based on environmental stability and condition quality. When environmental conditions are stable and favorable, the debounce time is reduced, allowing faster activation while maintaining continuity. When conditions are unstable or poor, the debounce time is increased to ensure continuous reliable operation. This dynamic adjustment resolves the contradiction between stability and availability
3Device complexity
If environmental conditions are not considered, then device complexity is reduced, but optimum setting of debounce times cannot be achieved
Solution Approach 1:
The system incorporates multiple environmental sensors (light sensors, weather sensors, camera systems) that serve multiple functions. These sensors not only detect environmental conditions for debounce time adjustment but also provide data for lane boundary detection and other assistant functions. This multi-functionality increases adaptability without proportionally increasing device complexity
Solution Approach 2:
The system changes debounce time parameters based on environmental conditions such as lighting levels, weather patterns, road surface characteristics, and lane marking visibility. By considering these environmental factors, the system achieves optimum debounce time settings that adapt to various driving scenarios, resolving the contradiction between complexity and adaptability

AI summary
A method for operating a lane guidance assistant of a vehicle includes the steps of: receiving environmental data which describe an environment of the vehicle; recognizing lane boundaries delimiting a lane in which the vehicle is currently located; automatically performing steering interventions to keep the vehicle in the lane if the lane boundaries are recognized for a predefined debounce time; continually determining environmental conditions, the environmental conditions describing a current location of the vehicle, weather in the environment, a current time of day and/or a road type associated with the lane; and adjusting the debounce time according to the continually determined environmental conditions.
