Vehicle Rear Lamp Display with Sensor-Driven Image Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle rear lamp assemblies primarily convey basic information like braking, turning, and reversing, lacking the ability to communicate more complex information such as obstacle detection, road conditions, door opening, and vehicle speed to other drivers effectively.
Innovation Solution
Integration of a controller with exterior and interior sensors, coupled with a lamp display module, which uses light sources and digital projection technology to render images and symbols on the rear lamp assembly, allowing it to display detected obstacles, road conditions, door status, and vehicle speed, enhancing communication with other drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional rear lamp assembly is used, then basic signaling function is maintained, but information communication capability is limited
Solution Approach 1:
The rear lamp assembly is transformed into a multi-functional communication device that not only performs traditional signaling (brake, turn, reverse) but also displays obstacle detection, road conditions, door status, and vehicle speed information through integrated sensors and display elements
Solution Approach 2:
Multiple functional components including position lamps, stop lamps, turn indicators, reverse lamps, sensors (exterior and interior), and display elements are merged into a single integrated rear lamp assembly controlled by a central controller to enable comprehensive information communication
2Reliability
If basic signaling only is provided, then device simplicity is maintained, but situational awareness enhancement is insufficient
Solution Approach 1:
The system incorporates exterior sensors that detect obstacles, road conditions, and vehicle status, providing feedback to the controller which then displays this information through the rear lamp assembly, creating a closed-loop feedback system that enhances situational awareness
Solution Approach 2:
The rear lamp assembly serves as an intermediary communication medium between the vehicle's internal sensor systems and external drivers, translating sensor data into visual displays that improve understanding of vehicle status and surroundings
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances safety by providing a more comprehensive and dynamic visual communication system for drivers, enabling them to better understand the vehicle's status and surroundings, thereby improving situational awareness and reducing potential collisions.
Implementation Method 1
A light source may be positioned inside the vehicle and directed toward a window
Implementation Method 2
The light from the light source may be projected onto a digital mirror device positioned behind the window
Data Source
AI summary
A vehicle includes a rear lamp display configured to display images as well as perform the usual functions of a rear lamp assembly. The rear lamp display may include a light source and a digital mirror device. Obstacles detected may trigger display of a static or animated representation of the obstacle in the rear lamp display. Detection of a turn may invoke display of a direction of the turn as well as text indicating a target of the turn. Detection of an intervention of a vehicle system to maintain stability, a warning may be displayed that indicates potentially hazardous road conditions. Where opening of a door is detected, a representation of an open or opening door may be displayed. Where a following vehicle is detected, the speed limit or cruising speed of the vehicle may be displayed. Objects left in the vehicle may trigger display of an alert.
