Vehicle Multimedia Device Dynamic Output Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle multimedia systems do not effectively manage the output of multimedia data from connected devices to minimize driver distraction during vehicle operation, potentially compromising road safety.
Innovation Solution
A vehicle multimedia device system that determines vehicle status information and transmits it to a connected computer device to produce clearance data, which limits the scope and output of multimedia data, such as images and sounds, to prevent excessive distraction, using bidirectional communication and dynamic adjustment based on driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia data output is allowed without restrictions, then user entertainment and information access are improved, but driver distraction increases and road safety deteriorates
Solution Approach 1:
The system dynamically adjusts multimedia output restrictions based on real-time vehicle status information. The control device receives vehicle status data (speed, acceleration, braking) and automatically modifies the scope of permitted multimedia output, transitioning from unrestricted to restricted modes as driving conditions require attention
Solution Approach 2:
The system changes the parameter of multimedia output scope based on vehicle status parameters. When vehicle status indicates safe driving conditions (low speed, steady state), broader multimedia output is permitted; when status indicates demanding driving conditions (high speed, frequent braking), the multimedia output scope is reduced or blocked
2Reliability
If multimedia output is restricted based on vehicle status, then driver safety is improved, but user entertainment capability is reduced
Solution Approach 1:
The control device periodically receives updated vehicle status information and dynamically adjusts multimedia output restrictions in real-time. This allows the system to temporarily permit multimedia output during safe driving periods while restricting during hazardous periods, providing periodic safety checks rather than continuous hard restrictions
3Object-affected harmful factors
If the system dynamically adjusts multimedia output based on vehicle status, then driver distraction is minimized, but system complexity increases
Solution Approach 1:
The control device performs multiple functions: it monitors vehicle status information, determines driving safety conditions, manages multimedia output restrictions, and communicates with both the output device and computer device. This multi-functionality consolidates what could be separate complex systems into a single coordinated control unit
Data Source
AI summary
The invention relates to the transmission of multimedia data, which is to be output, from a computer device to a vehicle multimedia device. The vehicle multimedia device has a control device which is designed to determine a piece of vehicle status information in order to transmit said information to the computer device. On the basis of the vehicle status information, the computer device generates release data which determines to what extent the multimedia data is to be output. The computer device transmits the multimedia data and the release data to the vehicle multimedia device, which multimedia device outputs, by means of an output device, the maximum multimedia data to the extent defined by the release data.
