Camera System Control Architecture for Commercial Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems for vehicles have complex structures due to separate control units for image capture and functional units, leading to increased system components, cables, and conductors, making them difficult to maintain and exchange.
Innovation Solution
A camera system where a single control signal is used to control both the image capture unit and functional units, reducing the number of system components and using a shared conductor and wiring system, with interfaces for stable signal transmission and multifunctional compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control units are used for image capture and functional units, then each component can be independently controlled, but the system structure becomes complex with increased cables and conductors
Solution Approach 1:
The patent combines the control of image capture units and functional units into a single integrated control architecture. A control unit uses a common signal line to send control signals to both the image capture unit and functional units, eliminating the need for separate control units and reducing system complexity while maintaining independent control capability through signal multiplexing.
Solution Approach 2:
The control unit is designed with multi-functionality to handle both image capture control and functional unit control through a universal signal interface. This universal control mechanism allows the same control unit to manage multiple different components using a common signal line, reducing the overall number of control units needed in the system.
2Ease of operation
If separate control units and wiring systems are used for image capture and functional units, then each unit can be independently controlled, but system costs and maintenance difficulty increase
Solution Approach 1:
The patent merges the wiring systems by using a common signal line for both image capture units and functional units. This consolidation reduces the total amount of cabling and conductors required, lowering material costs and simplifying installation and maintenance while preserving the ability to independently control each component type through the shared communication infrastructure.
3Adaptability or versatility
If multiple separate control units are used, then comprehensive control is achieved, but the number of system components and cables increases
Solution Approach 1:
The control unit is designed with universal multi-functionality to provide comprehensive control coverage for both image capture units and functional units. Through signal multiplexing and a standardized interface protocol, a single control unit can manage multiple different component types, achieving the same comprehensive control coverage that would otherwise require multiple specialized control units.

AI summary
A camera system (1) for a commercial vehicle has at least one image capture unit (3) for capturing an image, an image reproduction unit (8) for reproducing the captured image at least one functional unit (4.1, 4.2) for performing a vehicle function and at least one control unit (2) for outputting a control signal. The camera system (1) transmits a video signal between the control unit (2) and the image reproduction unit (8) and controls the image capture unit (3) and the functional unit (4.1, 4.2) by a control signal outputted from the control unit (2). The functional interface (6.1) is provided between the image capture unit (3) and the functional unit (4.1, 4.2), via which functional interface (6.1), image capture unit (3) and the functional unit (4.1, 4.2) are coupleable with each other and decoupleable from each other.
