Motor Vehicle Control Device for Adaptive Noise Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle noise transmission systems can only manually set interior noise levels, lacking the ability to automatically manipulate both interior and exterior noise levels in response to driver input.
Innovation Solution
A control device that automatically actuates the noise transmission and exhaust systems using characteristic maps to control shut-off devices, allowing for novel manipulation of interior and exterior noise levels through a common operating element, with independent maps for body type and engine conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual setting of interior noise level is implemented, then ease of operation is improved, but extent of automation is worsened
Solution Approach 1:
The control device automatically manipulates the noise transmission system and exhaust system based on driver input through a common operating element, eliminating the need for manual separate adjustments. The system serves itself by automatically adjusting shut-off devices according to stored characteristic maps that respond to engine conditions and driver actions.
2Extent of automation
If automatic actuation of noise transmission system and exhaust system is implemented, then extent of automation is improved, but device complexity is worsened
Solution Approach 1:
Characteristic maps are pre-stored in the control device, containing predetermined relationships between engine conditions, driver input, and desired noise levels. These maps are prepared in advance and automatically retrieved and applied when the common operating element is actuated, enabling automatic control without complex real-time calculations.
Solution Approach 2:
The control device integrates control of both the noise transmission system and exhaust system through a single common operating element. The same operating element triggers coordinated adjustment of interior noise levels and exterior noise levels, allowing one input to control multiple functions simultaneously.
