Coasting Coach Indicator Logic for Consecutive Deceleration Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in providing accurate coasting coach support when encountering consecutive learned deceleration areas in close proximity, leading to potential false impressions for drivers regarding the availability of support.
Innovation Solution
The vehicle identifies consecutive learned deceleration areas and determines their proximity, presenting a coasting coach indicator for the first area while disabling it for the second area to avoid giving a false impression of support availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the coasting coach indicator is presented for both consecutive learned deceleration areas, then the driver receives complete information about support availability, but the driver is given a false impression of support availability for the second area
Solution Approach 1:
The patent extracts the coasting coach indicator presentation for the second learned deceleration area when consecutive deceleration areas are detected. The system identifies the conflict between providing complete information and avoiding false impressions, then removes the indicator presentation for the second area to eliminate the false impression while maintaining accurate information about actual support availability.
Solution Approach 2:
The system performs preliminary detection of consecutive learned deceleration areas before presenting the coasting coach indicator. By anticipating the potential false impression issue, the system proactively prevents the indicator from being presented for the second area, thereby avoiding the harmful effect before it can occur.
2Loss of energy
If the vehicle provides coasting coach support for the first learned deceleration area, then fuel economy is improved, but the driver may be confused about support availability for the second area
Solution Approach 1:
The patent removes the coasting coach indicator presentation for the second learned deceleration area to eliminate driver confusion. By extracting this specific information presentation while maintaining the actual coasting support function for the first area, the system preserves fuel economy benefits while improving driver understanding of where support is actually available.
3Reliability
If the coasting coach indicator is disabled for the second learned deceleration area, then false impressions are avoided, but complete information about all deceleration areas is not provided
Solution Approach 1:
The patent converts the potential harm of incomplete information into a benefit by using the absence of the indicator for the second area as a clear signal of actual support availability. This negative indication (not showing the indicator) becomes a beneficial communication tool that accurately reflects the system's operational state and prevents driver misunderstanding.

AI summary
A vehicle can be configured to provide coasting coach support when approaching a learned deceleration area, advising on how to more efficiently operate the vehicle as it approaches the learned deceleration area. An indicator can be presented within the vehicle to inform the driver that coasting coach support is provided for the learned deceleration area. However, in certain situations, it may not be possible for a vehicle to provide coasting coach support for a learned deceleration area, such as may occur when the vehicle encounters two consecutive learned deceleration areas located in close proximity to each other. There may not be sufficient time to provide coasting coach support for the second of the two consecutive learned deceleration areas. In such instances, the vehicle can be configured to present the coasting coach indicator for the first deceleration area and to disable the coasting coach indicator for the second deceleration area.
