Vehicle Assistant System Common Image Data Analysis Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle assistant systems are costly and complex, making it impractical to install multiple systems in a single vehicle, and they often require separate data analysis units for different cameras, which increases weight and expense.
Innovation Solution
A hybrid vehicle assistant system that combines a first camera for capturing the front area and one or more second cameras for monitoring the interior, with a common image data analysis unit processing data from both, allowing for the integration of driver assistance and occupant monitoring functions while reducing the need for separate data analysis units and seat mats or sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate data analysis units are used for each camera system, then measurement precision and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple camera systems (front camera for driver assistance and interior camera for occupant monitoring) into a single integrated data analysis unit. This merging approach reduces system complexity and cost while maintaining the reliability needed for both driving assistance functions and occupant restraint system control through shared processing resources.
Solution Approach 2:
The common data analysis unit is designed to perform multiple functions: processing image data from the front camera for driver assistance systems and processing image data from the interior camera for occupant classification. This multi-functional approach allows a single unit to replace what would traditionally require separate dedicated processing units.
2Measurement precision
If multiple separate camera systems are installed, then measurement precision is improved, but cost and device complexity increase
Solution Approach 1:
The patent merges the data analysis capabilities for front camera and interior camera into a single common unit, reducing manufacturing costs by eliminating redundant processing hardware while maintaining the precision needed for both driver assistance and occupant detection functions.
Solution Approach 2:
The common data analysis unit provides universal processing capabilities that serve both driver assistance applications and occupant classification applications, reducing overall system cost while maintaining the measurement precision required for safety-critical functions.
3Reliability
If separate analysis units are used for front and interior cameras, then reliability is improved, but weight increases
Solution Approach 1:
By combining the data analysis functions for front and interior cameras into a single common unit, the patent reduces overall system weight while maintaining processing reliability through shared computational resources that are sufficient for both driver assistance and occupant monitoring tasks.
