Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sound systems fail to provide customizable and dynamic driving sounds, which can enhance driver experience and emotional satisfaction, especially in electric vehicles where noise and vibration are absent.
Innovation Solution
A vehicle sound control system that allows users to set response characteristics and section-specific volumes of driving sounds using an AVN system or mobile terminal, incorporating sensors to detect vehicle state information and control sound transfer characteristics, enabling the generation and output of various driving sounds through speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vehicle noise is reduced to improve comfort and concentration, then driving experience deteriorates due to loss of dynamic feedback
Solution Approach 1:
The system generates artificial vehicle driving sounds that copy and simulate the acoustic characteristics of actual engine sounds. The sound generation unit creates synthetic sounds based on vehicle state information (RPM, acceleration, braking) to replicate the dynamic feedback drivers expect, allowing noise reduction while preserving driving experience through artificial sound reproduction
Solution Approach 2:
The system dynamically adjusts sound parameters including volume, frequency distribution, and temporal characteristics based on real-time vehicle state information. The sound generation unit modifies acoustic parameters to match different driving conditions (acceleration, deceleration, steady state), enabling adaptive sound control that enhances comfort while maintaining driving feedback
2Adaptability or versatility
If artificial driving sounds are generated to enhance driving experience, then system complexity increases due to additional control units
Solution Approach 1:
The sound generation unit serves multiple functions: it generates artificial driving sounds, processes vehicle state information from various sensors, adapts sound characteristics based on driving conditions, and outputs controlled sound signals. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while providing comprehensive sound control
Solution Approach 2:
The sound generation unit acts as an intermediary between vehicle state sensors and the audio output system. It receives raw vehicle state information, processes it through sound synthesis algorithms, and generates appropriate acoustic outputs. This intermediary role simplifies the overall system architecture by centralizing the complex sound generation and control logic in a single unit rather than distributing it across multiple components

AI summary
A user may freely generate a vehicle driving sound using a mounted mobile terminal so as to generate various types of driving sounds through a speaker. A vehicle includes a setting unit configured to set response characteristics of a vehicle driving sound for at least one of a plurality of pieces of vehicle state information and set a section-specific volume of the vehicle driving sound for at least one of a plurality of set response characteristics including revolutions per minute (RPM) and a controller configured to control an output of the vehicle driving sound generated according to a setting of the setting unit and control sound transfer characteristics unique to the vehicle to be reflected when the vehicle driving sound is generated and output.
