Vehicle Quiet Mode Control for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles lack an integrated system to automatically adjust features such as exhaust and suspension settings in response to specific events, which can disrupt user experience during conversations, evasive driving, or other situations.
Innovation Solution
A vehicle system comprising a processor that detects predefined events and transitions multiple systems from a normal mode to a quiet mode by adjusting exhaust settings, engaging active noise cancellation, closing windows, and modifying suspension settings to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the vehicle operates in normal mode with standard exhaust and suspension settings, then performance and power are maintained, but noise levels increase and user comfort decreases during conversations or phone calls
Solution Approach 1:
The system dynamically transitions between normal mode and quiet mode based on detected events (phone calls, conversations). The exhaust system adjusts its operation mode, suspension modifies its characteristics, and windows automatically close to create an adaptive environment that reduces noise during communication events while maintaining normal operation otherwise.
Solution Approach 2:
The system changes multiple parameters simultaneously when transitioning to quiet mode: exhaust flow rate and sound characteristics are modified, suspension stiffness and damping are adjusted, and window positions are changed. These parameter changes collectively reduce noise and enhance comfort during communication events.
2Object-affected harmful factors
If the vehicle systems are manually adjusted for quiet operation, then noise reduction and comfort are improved, but system complexity and user operation burden increase
Solution Approach 1:
The system merges multiple previously independent control functions (exhaust control, suspension control, window control) into a single integrated quiet mode system. A central processor coordinates all these subsystems, allowing them to work together automatically in response to communication events, thereby reducing the perceived complexity for the user while maintaining sophisticated noise reduction capabilities.
Solution Approach 2:
The system automatically detects communication events (phone calls, conversations) and self-adjusts multiple vehicle systems without requiring user intervention. The processor monitors event conditions and autonomously transitions systems between modes, eliminating the need for manual operation while achieving comprehensive noise reduction and comfort enhancement.
3Ease of operation
If multiple vehicle systems are adjusted simultaneously for event response, then user experience is enhanced, but control system complexity increases
Solution Approach 1:
The control system is designed with multi-functionality to manage diverse vehicle subsystems (exhaust, suspension, windows) through a single unified controller. The processor executes comprehensive control logic that coordinates all these different functions based on event type, providing universal adaptability across multiple vehicle systems while presenting a simple interface to the user.
