Road Surface Projection Lamp for Advance Driver Event Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lamp systems lack effective means to provide advance information to drivers about upcoming events on the road, such as narrow roads or direction changes, which can lead to safety concerns due to inadequate notification and awareness.
Innovation Solution
A lamp system that includes a road surface drawing lamp and a controlling unit to project patterns on the road surface, combining with a head-up display to present first information before an event and second information at the event onset, utilizing a light distribution variable lamp and a HUD to assist drivers with drive assistance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle lamp systems use conventional illumination methods, then the structure is simple, but the ability to provide advance information to drivers about upcoming road events is insufficient
Solution Approach 1:
The system performs preliminary action by projecting a first pattern on the road surface before a predetermined event occurs, providing advance information to the driver about upcoming road conditions or events, allowing the driver to prepare and respond appropriately
Solution Approach 2:
The information presentation is segmented into two distinct patterns: a first pattern for advance notification and a second pattern for current event indication. This segmentation allows the system to convey different types of information at different times, improving overall information delivery effectiveness
2Reliability
If the lamp system projects patterns on the road surface, then driver awareness of road events is improved, but the device complexity increases due to additional control units and lighting components
Solution Approach 1:
The lamp system is designed with multi-functionality, where the same road surface drawing lamp and control unit serve both conventional illumination purposes and the additional function of projecting informational patterns, reducing the need for entirely separate systems
Solution Approach 2:
The control unit acts as an intermediary that receives information about upcoming events and translates it into visual patterns projected on the road surface, bridging the gap between event detection systems and driver notification

Function Achieved in This Case
Enhances traffic safety by providing clear advance notice and relevant information to drivers through projected patterns on the road and HUD, allowing timely responses to road conditions and events, reducing the risk of accidents.

AI summary
A lamp system includes a road surface drawing lamp that illuminates a road surface with a beam BM, and a lamp controlling unit that controls the road surface drawing lamp and draws, with the beam BM, a pattern PTN on the road surface ahead of a vehicle. The lamp controlling unit draws a first pattern before a start of a predetermined event and draws a second pattern at the start of the event. The first pattern includes first information to be presented in advance to a driver to allow the driver to respond to the event, and the second pattern includes second information corresponding to the event.
