Solution Overview
Problem
Current monitoring systems for vehicles lack effective means to detect tailgating events and provide real-time notifications and evidence to drivers and law enforcement agencies, especially in situations where manual intervention is challenging.
Innovation Solution
A monitoring assembly comprising a rear-facing sensor, display, and imager system integrated with a vehicle's onboard control system and internet connectivity, which uses programming code to determine separation distances, provide driver notifications, capture images, and communicate tailgating events to law enforcement via the internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring of tailgating is performed, then driver attention is required, but response time is delayed and safety is reduced
Solution Approach 1:
The system enables self-service by automatically detecting tailgating events through sensors and imaging devices, generating notifications without requiring driver intervention. The onboard control system autonomously processes sensor data, determines tailgating events, and communicates with following vehicles, allowing the vehicle to monitor and respond to tailgating conditions independently.
Solution Approach 2:
The patent replaces manual mechanical monitoring with automated electronic detection systems. Sensors, imagers, and computer vision algorithms substitute for human driver attention, while electronic communication systems replace manual signaling methods. This substitution enables continuous, real-time monitoring without the delays and limitations of human response.
2Ease of operation
If no automated notification system is used, then system complexity is low, but driver awareness of tailgating events is insufficient
Solution Approach 1:
The system implements feedback by detecting tailgating events through sensors and immediately communicating with the following vehicle via displays or notifications. This closed-loop feedback mechanism provides real-time information about tailgating conditions to both the lead and following vehicles, enabling timely driver awareness and response without requiring complex manual monitoring procedures.
3Reliability
If evidence is not automatically captured and transmitted, then device complexity is reduced, but law enforcement capabilities are limited
Solution Approach 1:
The system performs preliminary action by automatically capturing images and video evidence of tailgating events as they occur, storing them onboard, and preparing them for transmission to law enforcement agencies. This preliminary evidence collection eliminates the need for manual documentation later and ensures evidence is preserved in real-time, enhancing enforcement capabilities through automated documentation and transmission systems.

AI summary
A tailgating detection and monitoring assembly for a vehicle includes a sensor, a display, and a rear-facing imager that are coupled to a vehicle. The sensor and the display are rear-facing. A computer is operationally coupled to the rear-facing imager, the sensor, the display, and an onboard control system of the vehicle. Programming code that is positioned on the computer enables the computer to actuate the sensor to determine a separation between the vehicle and a following vehicle, positioning an automatic braking system of the vehicle to determine a tailgating event. The programming code enables the computer to selectively actuate the display to present a notification to a driver of the following vehicle and to selectively actuate the rear-facing imager to capture an image of the tailgating event. The onboard control system is positioned to communicate the image of the tailgating event to a law enforcement agency via the internet.
