Vehicle Lamp System Mode Detection and Adaptive Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coexistence of automatic driving vehicles and manual driving vehicles on public roads poses a challenge in effectively communicating intentions and navigating safely, as existing systems struggle to adapt to different driving modes.
Innovation Solution
A vehicle lamp system that includes a mode determination unit to identify the driving mode of other vehicles and a lamp control unit to adjust the lighting displays accordingly, using a road surface drawing lamp and signaling lamps to convey intentions based on whether the oncoming vehicle is in automatic or manual driving mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a vehicle lamp system uses fixed lighting displays for all driving modes, then the system is simple to operate, but it cannot effectively communicate intentions to vehicles in different driving modes
Solution Approach 1:
The lamp control system dynamically adjusts lighting displays based on the detected driving mode of the own vehicle and other vehicles. The control unit selects different lighting patterns from multiple options depending on whether the vehicle is in manual or automatic driving mode, making the communication system adaptive rather than static.
Solution Approach 2:
The system changes lighting parameters such as brightness, color, and illumination patterns based on the driving mode. For example, different colors or intensities are used to indicate whether the vehicle is in manual or automatic mode, enabling other vehicles to understand the current driving state and adjust accordingly.
2Reliability
If the lamp system adapts to different driving modes of other vehicles, then communication accuracy improves, but the device complexity increases
Solution Approach 1:
The lamp control system acts as an intermediary that translates the driving mode information (detected by the mode determination unit) into appropriate lighting signals. This mediator function enables indirect communication between vehicles of different driving modes without requiring direct complex interaction between all system components.
Solution Approach 2:
The control system is segmented into distinct functional units: a mode determination unit that detects driving modes, a lamp control unit that processes this information, and multiple lamps that execute specific lighting patterns. This segmentation allows each unit to perform its function independently, simplifying the overall system architecture.
3Loss of information
If the system uses multiple lighting patterns for different scenarios, then communication effectiveness improves, but the ease of operation decreases
Solution Approach 1:
The lamp control system operates autonomously by automatically detecting the driving mode of the own vehicle and other vehicles, then selecting and executing appropriate lighting patterns without requiring manual input from the driver. The system serves itself by making real-time adjustments based on detected conditions.
Solution Approach 2:
The system uses feedback from the mode determination unit about the detected driving modes to continuously adjust the lighting displays. This closed-loop control ensures that the lighting patterns remain appropriate for the current traffic situation, with the control unit receiving ongoing information about vehicle modes and responding accordingly.

AI summary
This vehicle lamp system, which is used together with a vehicle control unit that controls the travel state of a vehicle and a mode determination unit that can determine an automatic driving mode of another vehicle, comprises a lamp mounted on the vehicle, and a lamp control unit which, depending on the mode signal outputted by the mode determination unit, controls the lamp in different ways (for example, displaying an arrow with road surface rendering).
