In-Vehicle Control for Self-Driving Cabin Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle control systems do not effectively enhance the comfort of vehicle interiors during self-driving, as they fail to adequately restrict unnecessary device operations and reduce noise and distractions, leading to a less comfortable environment for occupants.
Innovation Solution
An in-vehicle control apparatus and method that determines the direction of a driver's seat and whether a vehicle is self-driving, controlling device operations to restrict unnecessary functions, such as direction indicator sounds, wiper operations, display brightness, and navigation voice volumes, based on these determinations to improve interior comfort and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If device operations are restricted during self-driving to improve comfort, then interior comfort and power consumption are improved, but device functionality and user accessibility are reduced
Solution Approach 1:
The control apparatus dynamically adjusts device operations based on the driving mode. During self-driving, the system automatically restricts certain device functions (like direction indicator sounds, wiper operations, display brightness, navigation voice volumes) to reduce noise and distractions, while maintaining full functionality when manual driving is detected. This dynamic adaptation resolves the contradiction by making device behavior flexible rather than fixed.
Solution Approach 2:
The system changes operational parameters of devices based on driving mode detection. When self-driving is detected, parameters such as sound volume, display brightness, and operation frequency are automatically adjusted to more restrictive values. When manual driving is detected, parameters return to normal values. This parameter-based control allows the system to optimize comfort without permanently limiting device capabilities.
2Ease of operation
If the driver's seat is turned backward to enable self-driving mode, then occupant comfort is improved, but traditional driving functionality is compromised
Solution Approach 1:
The control apparatus detects the driver's seat direction in advance and proactively switches device operations to the appropriate mode. When the seat is turned backward, the system preemptively activates self-driving mode restrictions on device operations. When the seat is turned forward, it preemptively restores normal driving functionality. This preliminary detection and response ensures seamless transition between modes without compromising either comfort or functionality.
Solution Approach 2:
The system continuously monitors the driver's seat direction and uses this feedback to automatically adjust device operations. The seat position sensor provides real-time feedback about whether the driver is facing forward or backward, and the control apparatus responds by enabling or restricting device functions accordingly. This closed-loop feedback mechanism ensures that the system adapts to the actual driving state, maintaining both comfort and functionality as needed.
