Motor Vehicle Interior Lighting Control via Segmented Peripheral Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle interior lighting systems lack efficient and centralized control mechanisms to generate complex lighting effects, such as running lights, while also providing hazard alerts to drivers, which can be distracting and difficult to implement without overloading data bus technologies.
Innovation Solution
A motor vehicle system comprising a central light control device and multiple peripheral light control devices, each controlling a set of interior light modules via a data bus, where light effect identifiers are transmitted to generate predefined lighting effects, including running lights, and a hazard detection device outputs specific identifiers to trigger attention and running lights in response to detected hazards, allowing for synchronized and decentralized control of light sources across the vehicle.

Engineering Contradiction Analysis
1Extent of automation
If a central control device controls all light sources directly, then centralized control is achieved, but data bus load increases and system complexity increases
Solution Approach 1:
The control system is segmented into a central control device that sends light effect identifiers and multiple peripheral light control devices that execute the effects. This segmentation distributes the control burden, reducing data bus load while maintaining centralized coordination. Each peripheral device independently controls its assigned light sources based on received identifiers.
Solution Approach 2:
Light effect identifiers act as intermediaries between the central control device and peripheral light control devices. Instead of the central device directly controlling each light source, it transmits compact identifier signals that peripheral devices interpret and execute, significantly reducing data bus communication load.
2Adaptability or versatility
If multiple light control devices are distributed throughout the vehicle, then control flexibility improves, but system complexity increases
Solution Approach 1:
Multiple peripheral light control devices are equipped with identical control functionality and memory structures. Each device can store and execute the same set of light effect identifiers, allowing any device to perform any lighting effect. This universal design provides control flexibility while using standardized, replicable components rather than complex custom designs.
Solution Approach 2:
The control functionality is copied across multiple peripheral devices rather than creating a complex hierarchical control structure. Each peripheral device contains a copy of the light effect identifier storage and execution capability, simplifying the overall system architecture through replication of simple, identical units.
3Adaptability or versatility
If complex lighting effects are implemented, then lighting functionality improves, but data bus load increases
Solution Approach 1:
Light effect identifiers are pre-defined and stored in the peripheral light control devices' memory before execution. When a lighting effect is desired, the central device simply transmits the pre-packaged identifier rather than sending detailed control parameters, reducing real-time data bus load while enabling complex lighting effects.
Solution Approach 2:
The system transitions from transmitting detailed control parameters for each light source to transmitting compact light effect identifiers. This parameter transformation condenses complex lighting effect definitions into simple identifier signals, reducing data bus communication requirements while maintaining lighting effect versatility.
