Driving Feedback Audio for Stable Vehicle Behavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support systems fail to provide real-time driver performance evaluations without distracting the driver, making it difficult for them to understand when and how their performance is being assessed.
Innovation Solution
A driving support apparatus that uses auditory feedback, specifically reward sounds, to inform drivers of their performance stability based on vehicle behavior data, allowing them to understand their performance intuitively and maintain high driving standards without being distracted from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual displays or text evaluations are used to inform drivers of their performance, then driver performance feedback is provided, but driver distraction increases
Solution Approach 1:
The patent replaces visual feedback mechanisms (displays, text) with auditory feedback mechanisms (reward sounds). This substitution allows performance evaluation information to be transmitted to the driver through sound rather than visual channels, thereby providing necessary feedback while eliminating the distracting effect of visual displays that would compete for the driver's attention.
Solution Approach 2:
The patent introduces auditory reward sounds as an intermediary medium to convey driver performance evaluation. Instead of directly presenting visual information that distracts the driver, the system uses sound as a mediator to transmit performance feedback in a non-intrusive manner that does not compete with visual driving tasks.
2Productivity
If real-time performance evaluation is provided to drivers, then driver motivation is boosted, but cognitive load increases
Solution Approach 1:
The patent applies local quality by providing differentiated auditory feedback (different reward sounds) for different performance levels or driving segments. This localized, segment-specific feedback approach motivates drivers through positive reinforcement while keeping each feedback instance simple and easy to process, avoiding overwhelming the driver with complex continuous evaluations.
Solution Approach 2:
The patent implements periodic action by providing performance feedback at regular intervals or at the completion of specific driving segments rather than continuously. This periodic feedback structure allows drivers to receive motivational reinforcement without experiencing constant cognitive load from continuous evaluation processing.
3Measurement precision
If detailed performance data is processed and displayed, then evaluation precision is improved, but system complexity increases
Solution Approach 1:
The patent extracts only the essential performance evaluation information needed to convey driver performance adequacy and translates it into simple auditory reward sounds. Instead of processing and displaying all detailed performance data which would increase system complexity, the system extracts the key evaluation result and presents it in a simplified auditory form that maintains evaluation precision while reducing processing burden.
Data Source
AI summary
A driving support apparatus includes a controller. While the vehicle is driving, the controller is configured to obtain data indicating behavior of a body of a vehicle and output a certain sound based on information indicating stability of the behavior determined from the obtained data. Every time the vehicle drives a predetermined segment, the controller is configured to output a reward sound in accordance with the stability of the behavior in the predetermined segment.
