In-Vehicle Camera Setting via ECU Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for managing in-vehicle cameras across multiple vehicle models are costly due to the need for individual vehicle setting information to be pre-written in each camera, requiring complex correspondence management based on product numbers.
Innovation Solution
An in-vehicle camera setting method where individual vehicle setting information stored in the ECU is written into the in-vehicle camera after connection, allowing for standardized camera hardware across different vehicle models and reducing the need for strict model-based identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual vehicle setting information is pre-written in each in-vehicle camera based on product numbers, then correct vehicle-camera correspondence can be achieved, but the cost of managing in-vehicle cameras increases and device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing individual vehicle setting information in the ECU before the camera is installed. The ECU reads the camera's product number and retrieves the corresponding pre-stored setting information, eliminating the need for manual pre-writing in each camera and reducing management complexity while maintaining correspondence accuracy
Solution Approach 2:
The patent introduces the ECU as an intermediary between the camera and the vehicle setting information. The ECU stores multiple sets of setting information corresponding to different camera product numbers and automatically selects the correct set based on the camera's product number, thereby simplifying camera management while ensuring accurate correspondence
2Reliability
If individual vehicle setting information is pre-written in each in-vehicle camera, then correct vehicle-camera correspondence can be achieved, but the cost of managing in-vehicle cameras increases
Solution Approach 1:
The patent merges the storage function for multiple vehicle setting information into a single ECU component. Instead of requiring each camera to be individually pre-configured, the ECU consolidates all setting information and automatically matches it with the camera based on product number, thereby reducing management costs while maintaining correspondence accuracy
Solution Approach 2:
The system applies self-service by enabling the ECU to automatically read the camera's product number and select the corresponding setting information without human intervention. This automated process eliminates manual configuration work and reduces management costs while ensuring accurate vehicle-camera correspondence
