AVN Head Unit Controller for Automatic Lighting and Window Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle multimedia systems face user convenience issues when drivers manipulate external devices, particularly in low light conditions or when weather information is accessed, leading to inconvenient lighting and window/sunroof control during vehicle operation.
Innovation Solution
A head unit controller that interacts with user devices to automatically control in-vehicle lighting and window/sunroof settings based on signal sensitivity and predetermined logic, determining user device position and sending appropriate control signals for lighting and weather-related adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver uses external device functions (iris recognition, camera) in low light conditions, then the device functionality is utilized, but the driver experiences inconvenience due to insufficient lighting
Solution Approach 1:
The system performs preliminary action by automatically turning on the vehicle lighting when it detects that the driver is using functions requiring light (iris recognition, camera) in low light conditions. The controller monitors the state of the external device and ambient light levels, and proactively activates the lighting before the driver experiences inconvenience, thus resolving the contradiction between device usability and lighting adequacy.
2Ease of operation
If the driver manually controls lighting and window/sunroof, then precise control is achieved, but user convenience is reduced due to manual intervention requirements
Solution Approach 1:
The system implements self-service by automatically controlling lighting, windows, and sunroof based on weather information received from the external device. The controller monitors weather data (rain, fine dust levels) and autonomously adjusts vehicle systems without requiring manual driver input, thereby improving user convenience while increasing automation extent.
Solution Approach 2:
The system uses feedback from weather information received from the external device to automatically adjust vehicle systems. The controller continuously monitors weather data and uses this feedback to make real-time adjustments to lighting, windows, and sunroof, creating a closed-loop control system that enhances convenience through automation.
3Reliability
If the vehicle remains in opened window or sunroof state, then ventilation is maintained, but the vehicle travels unsafe in bad weather conditions
Solution Approach 1:
The system performs preliminary action by proactively closing windows and sunroof when adverse weather conditions (rain, high fine dust) are detected from weather information. The controller monitors weather data in advance and automatically adjusts vehicle openings before the driver encounters unsafe conditions, thus improving reliability while maintaining operational convenience through automation.
