Emotion-Adaptive Driving Assistance for Occupant State Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to provide appropriate assistance tailored to the emotional state of the vehicle occupant, leading to potential further deterioration of the occupant's emotional state and reduced safety during driving.
Innovation Solution
A driving assistance apparatus equipped with a traveling state detector, an occupant monitoring detector, an emotion determination processor, an environment recognizer, and a driving assistance processor, which detects the vehicle's traveling state, monitors the occupant's state, determines the occupant's emotion, recognizes the environment, and performs driving assistance control, including information presentation and traveling assistance, based on these factors to vary control operations according to the occupant's emotional state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving assistance control is performed without considering the occupant's emotional state, then the control system is simple, but the assistance is not appropriate and may worsen the occupant's emotional state
Solution Approach 1:
The system segments the emotional determination into multiple distinct emotions (anxious, angry, impatient, confused, normal) and processes each with specific control strategies. This segmentation allows the system to handle different emotional states independently with tailored responses, improving reliability while managing complexity through modular processing.
Solution Approach 2:
The driving assistance processor serves multiple functions: it performs standard driving assistance control while simultaneously adapting control operations based on detected emotional states. This multi-functionality allows a single system to provide both routine assistance and emotion-adaptive assistance, improving safety without requiring entirely separate systems.
2Adaptability or versatility
If multiple kinds of emotions are determined and control operations are varied accordingly, then the assistance becomes more appropriate, but the device complexity increases
Solution Approach 1:
The system applies different control operations for different emotional states rather than using a uniform approach. Each emotion type (anxious, angry, impatient, confused) receives customized control adaptations, such as adjusting information presentation or traveling assistance based on the specific emotional state, improving adaptability through localized responses.
Solution Approach 2:
The control operations dynamically adjust based on the detected emotional state. The system continuously monitors emotional changes and modifies control strategies in real-time, making the assistance adaptable to changing emotional conditions while maintaining manageable complexity through dynamic rather than static control.
3Reliability
If the system monitors and responds to multiple emotional states, then safety improves, but the difficulty of detecting and measuring emotional states increases
Solution Approach 1:
The emotion determination processor acts as an intermediary that translates complex biometric data and behavioral observations into simplified emotional state classifications. This intermediary layer processes multiple input signals (biometric information, camera images, audio) and converts them into discrete emotion categories, making detection more manageable while improving safety through accurate emotional awareness.

AI summary
A driving assistance apparatus to be applied to a vehicle includes a traveling state detector, an occupant monitoring detector, an emotion determination processor, an environment recognizer, and a driving assistance processor. The emotion determination processor determines an emotion of an occupant of the vehicle, based on outputs of the traveling state detector and the occupant monitoring detector. The driving assistance processor performs driving assistance control including one or both of information presentation to the occupant and traveling assistance control on the vehicle, in accordance with an output of one or more of the traveling state detector, the emotion determination processor, and the environment recognizer. The emotion determination processor determines multiple kinds of emotions less suitable for driving than a normal emotion. The driving assistance processor varies a control operation included in the driving assistance control, depending on a kind of the emotion determined by the emotion determination processor.
