Vehicle Music Selection System Using Multi-Parameter Driver State Analysis

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional music selection systems in vehicles primarily focus on a single environmental parameter, leading to decreased driver satisfaction due to the neglect of multiple complex parameters affecting the driving experience.

Innovation Solution

A music selection system that collects and considers multiple vehicle parameters such as exterior environment information, traveling information, interior environment information, and driver state information to classify and automatically select songs, ensuring continuous playback within the same category when a driver selects a song.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the driver directly selects a desired song, then the driver can listen to the selected song, but the driver's eyes are diverted from the road, thereby increasing the risk of an accident

Engineering Contradiction:

Improvesong selectionVSAvoiddriving safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system enables self-service by automatically selecting songs based on driver state information (heart rate, biorhythm, emotional quotient) without requiring manual driver input, thus eliminating the need for the driver to divert attention from the road while still providing personalized music selection

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors driver state parameters (heart rate, biorhythm, emotional quotient) and uses this feedback to dynamically adjust and select appropriate songs, creating a closed-loop system that adapts to the driver's real-time condition

Inventive Principle:

Principle #23Feedback

2Extent of automation

If the system selects a song based on only one environmental parameter, then the system can automatically select a song, but the driver's satisfaction with the song selection is decreased

Engineering Contradiction:

Improveautomatic song selectionVSAvoiddriver satisfaction

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system merges multiple environmental parameters (driver state information including heart rate, biorhythm, emotional quotient, weather conditions, and vehicle information) into a unified song selection process, combining these diverse inputs to make comprehensive automated decisions that satisfy driver preferences

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs multiple functions simultaneously by monitoring various driver state parameters (heart rate, biorhythm, emotional quotient) and environmental conditions (weather, vehicle state) to make a single integrated song selection decision, making the system versatile and adaptable to different situations

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A music selection system and method in a vehicle is provided. The system includes a vehicle traveling information collection unit configured to collect vehicle traveling information, a vehicle exterior environment information collection unit configured to collect vehicle exterior environment information, a vehicle interior environment information collection unit configured to collect vehicle parameter values to enable songs selected by a driver to be matched with the vehicle parameter values and stored in corresponding classification categories, thereby allowing other songs in the same category to be selected and played when the selected song is played.
