Vehicle Message Board Using OBD Data for Driver Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle messaging systems are ineffective in reducing road rage as they require active user input, distract drivers, and lack integration with vehicle systems, failing to provide a comprehensive means of communication between drivers.
Innovation Solution
A vehicle messaging system that includes a remote and message board communicatively coupled to receive user input, vehicle data via the OBD port, and display messages automatically, using voice recognition, sensors, and AI to generate de-escalating messages without requiring driver attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing remote-controlled display systems are used, then drivers can communicate with other drivers, but the systems require active user input which distracts drivers from the road
Solution Approach 1:
The system automatically generates and displays messages based on vehicle data from the OBD port without requiring driver input. The microcontroller reads vehicle parameters (speed, acceleration, engine status) and autonomously determines when to display messages to other drivers, making the system self-serve the communication function while the driver remains undisturbed
Solution Approach 2:
The patent replaces manual mechanical input (pressing buttons on a remote) with automated electronic sensing and processing. The system uses the OBD port to electronically read vehicle data and automatically translates it into display messages, substituting the mechanical interaction model with an automated electronic control model that eliminates driver distraction
2Ease of operation
If existing display systems are used, then messages can be displayed to other drivers, but the systems are not integrated into the vehicle's systems
Solution Approach 1:
The patent merges the messaging display system with the vehicle's existing OBD (On-Board Diagnostics) system. By connecting to the OBD port, the display system integrates with the vehicle's native data infrastructure, allowing it to read vehicle parameters directly without requiring separate sensors or communication protocols, thus reducing overall system complexity while improving integration
Solution Approach 2:
The OBD port serves multiple functions: it provides power to the display system, transmits vehicle data for message generation, and enables communication between different vehicle systems. This multi-functionality reduces the need for dedicated components, simplifying the overall system architecture while achieving deep vehicle integration
3Adaptability or versatility
If existing systems are used, then drivers can manually control message display, but they cannot effectively communicate specific driver intent
Solution Approach 1:
The system continuously monitors vehicle parameters through the OBD port (speed, acceleration, engine status) and uses this feedback to automatically determine when and what to display. This closed-loop feedback mechanism translates subtle vehicle state changes into meaningful communication messages, providing high expressiveness without requiring the driver to manually select or control the messaging

AI summary
A messaging system includes a message board and a remote communicatively coupled to the message board and configured for receiving a user input. In the system, the remote is configured to transmit a message to the message board with instructions for displaying a message based on the user input. In some configurations, the messaging system can be installed in a vehicle. In such configuration, the message board can be communicatively coupled to an on-board diagnostics port of the vehicle.
