Virtual Driving Sound Control Using Radio-Based Sound Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles lack the ability to generate customizable virtual driving sounds in real-time based on a driver's preference, requiring manual intervention and limiting the dynamic driving experience and pedestrian awareness.
Innovation Solution
A vehicle system that automatically receives radio signals to extract sound sources and generates customized virtual driving sounds based on driving state information, allowing for real-time output to the interior or exterior of the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a driver manually implants a separate sound source into the vehicle to generate customized virtual driving sounds, then customized virtual driving sounds can be generated, but the driver cannot perform this operation while driving due to safety concerns
Solution Approach 1:
The system automatically receives sound sources from external servers through radio communication and performs self-updating of virtual driving sounds without requiring manual driver intervention. The vehicle's control system autonomously completes the sound source implantation process, resolving the contradiction between customization capability and operational safety.
Solution Approach 2:
Sound sources are pre-prepared and stored on external servers before being transmitted to the vehicle. The vehicle system has sound sources ready for immediate use, eliminating the need for drivers to manually implant them during driving operations.
2Ease of operation
If only basic virtual driving sounds prepared by the manufacturer are used, then the system is simple to operate, but drivers cannot experience customized driving sounds matching their specific preferences
Solution Approach 1:
The vehicle system maintains compatibility with basic manufacturer-prepared sounds while simultaneously acquiring the ability to receive and use customized sound sources from external servers. This multi-functionality allows the system to serve both simple and customized needs without compromising ease of operation.
Solution Approach 2:
The sound system transitions from static basic sounds to dynamic customized sounds that can be automatically updated and changed based on driver preferences and regional characteristics, while maintaining the simplicity of using basic sounds when desired.
3Device complexity
If the vehicle uses pre-set basic virtual driving sounds, then no additional complexity is introduced to the system, but the driving experience and pedestrian awareness are limited
Solution Approach 1:
External servers act as intermediaries that store and transmit customized sound sources to the vehicle. This intermediary system handles the complexity of sound source management, allowing the vehicle's sound generation system to remain relatively simple while still accessing diverse customized sounds.
Data Source
AI summary
A vehicle and a control method are for generating a virtual driving sound. The control method for the vehicle may include: receiving a radio signal including a sound source through an antenna of the vehicle; extracting the sound source from the received radio signal; generating a virtual driving sound representing a driving state of the vehicle based on the extracted sound source; and outputting the virtual driving sound to an interior or an exterior of the vehicle.
