Vehicle Light Control System Tracking Portable Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light control systems in motor vehicles do not provide adaptive and user-centric lighting assistance, as they lack the ability to dynamically track the user and adjust lighting based on individual requirements and environmental conditions.
Innovation Solution
A light control system that includes a light controller, a portable user identification device (UID), and a communication interface, allowing the lighting unit to automatically track the user's motion trajectory and switch between assistance functions based on user input and environmental conditions, using magnetic field or acoustic signal exchange for passive communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light beam is fixed in orientation, then the lighting system is simple to control, but it cannot adapt to user movement and provides suboptimal lighting assistance
Solution Approach 1:
The lighting system transitions from a fixed orientation to a dynamic tracking mode where the light beam automatically follows the user's motion trajectory. The control unit continuously receives position data from the portable device and adjusts the lighting unit's orientation in real-time, enabling the system to adapt to user movement while maintaining manageable complexity through automated control.
2Productivity
If the light control system continuously tracks the user, then lighting assistance is optimized, but energy consumption increases
Solution Approach 1:
Instead of continuous tracking, the system uses periodic position updates from the portable device. The control unit receives position data at intervals and adjusts the light beam orientation accordingly. This periodic operation maintains effective lighting assistance while significantly reducing energy consumption compared to continuous real-time tracking.
3Ease of operation
If the light beam follows the portable unit, then user assistance is improved, but glare may occur to the user
Solution Approach 1:
The lighting system applies different quality characteristics to different regions of the light beam. The control unit adjusts the orientation and intensity distribution so that the illuminated area follows the user's position while the beam direction is carefully controlled to avoid shining directly into the user's eyes. This creates locally optimized lighting that provides assistance without causing glare.

AI summary
An assistance method for a light control system in a motor vehicle, having a light controller for controlling a lighting unit in the motor vehicle for lighting a motor vehicle environment, a portable unit, at least one communication interface, and an evaluation unit for evaluating signals from the portable unit received via the communication interface. The lighting unit being controllable by the light controller and in accordance with the evaluation of the signals received from the portable unit in a first assistance function, such that at least one light beam emitted by the lighting unit can be positioned as a function of the position of the portable unit. The lighting unit is controlled via the light controller, such that when the first assistance function is switched on, the light beam emitted by the lighting unit automatically tracks the portable unit in accordance with the motion trajectory of the portable unit.
