Vehicle Emotion-Based Drive Ability Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle drive ability development relies on subjective evaluations, which fail to cater to the emotional states of users, leading to unsatisfactory driving experiences.
Innovation Solution
A vehicle system equipped with a sensing unit to measure acceleration and bio-signals, and a control unit that determines emotion states and adjusts drive ability factors such as speed responsiveness, linearity, and acceleration capability based on measured bio-signals and correlation information.

Engineering Contradiction Analysis
1Adaptability or versatility
If subjective evaluation by drive ability evaluation experts is used to develop drive ability, then drive ability can be adjusted through EMS software settings, but user satisfaction cannot be fully satisfied as it does not account for individual emotion states
Solution Approach 1:
The system continuously monitors user bio-signals (heart rate, skin conductance, temperature) and vehicle acceleration data, processes this information to determine emotion states, and uses this feedback to dynamically adjust drive ability factors. This closed-loop feedback mechanism enables the system to adapt to individual user emotion states in real-time, transforming the previously open-loop subjective evaluation process into an adaptive system that accounts for individual emotional responses.
Solution Approach 2:
The system enables users to indirectly express their emotional states through bio-signal measurements and acceleration data, allowing the drive ability to self-adjust based on detected emotion states without requiring explicit user input or manual adjustments. The system serves itself by using its own sensors and processors to monitor user state and automatically modify performance characteristics.
2Adaptability or versatility
If bio-signal measurement and emotion state determination are added to the vehicle system, then drive ability can be dynamically adjusted based on user emotion, but device complexity increases due to additional sensing and control components
Solution Approach 1:
The sensing unit and control unit are designed to perform multiple functions: the sensing unit measures both acceleration and various bio-signals (heart rate, skin conductance, temperature), while the control unit processes this data to determine emotion states and adjusts multiple drive ability factors (acceleration, deceleration, speed responsiveness). This multi-functional design consolidates what could be separate specialized systems into integrated units, reducing overall system complexity.
Solution Approach 2:
The patent combines the sensing of acceleration and bio-signals into a single sensing unit, and merges the processing of emotion state determination with the control of drive ability factors in a single control unit. This consolidation integrates previously separate functions (vehicle motion sensing, physiological monitoring, emotion analysis, and performance control) into unified systems, simplifying the overall architecture despite the increased functionality.

AI summary
A vehicle configured for determining an emotion state of a user, and adjusting a speed change of the vehicle that exerts an influence on the drive ability on the basis of the determined emotion state, and a method of controlling the same, may include a sensing unit configured to measure an acceleration of a vehicle and a bio-signal of a user; and a control unit connected to the sensing unit and configured to determine emotion state information indicating an emotion state of the user on the basis of the measured bio-signal when the measured acceleration is greater than or equal to a threshold acceleration, and on the basis of the emotion state information and correlation information indicating a relationship between the emotion state information and a drive ability factor related to a drive ability according to a speed change of the vehicle, update a setting value of the drive ability factor.
