Driver Advisory System for Real-Time Vehicle Status Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing information about vehicle status on highways are incomplete and inconvenient, as advisory message signs are limited in urban areas and radio broadcasts are infrequent, focusing on aftereffects rather than real-time data, and do not provide information on vehicle operations or occupant status.
Innovation Solution
A driver advisory system that uses sensors, electronic circuits, and communication units to transmit and receive information about vehicle parameters, such as hazardous conditions, to and from nearby vehicles, including alerts tailored to driving conditions, using a combination of sensors like switch-based, inductive, vision, and radar sensors, and a human-machine interface for alerting drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If variable advisory message signs are used to provide information about vehicle status, then information dissemination is achieved, but the coverage is limited to urban highways and the signs are situated at distant intervals making them difficult to read
Solution Approach 1:
The patent replaces the mechanical system of physical advisory message signs with an electronic communication system using transceivers, sensors, and digital message transmission. This substitution enables continuous real-time information exchange between vehicles and infrastructure, eliminating the limitations of fixed sign locations and intermittent visibility while providing comprehensive vehicle status data including occupant presence, vehicle operation state, and hazard conditions.
2Loss of time
If radio broadcasts are used to provide highway status information, then information is disseminated to vehicles, but the broadcasts are provided infrequently and focus on aftereffects rather than real-time data
Solution Approach 1:
The patent implements continuous real-time monitoring and communication through sensors and transceivers that constantly exchange vehicle status information. Unlike intermittent radio broadcasts, the system maintains continuous data flow about vehicle operations, occupant status, and hazard conditions, enabling immediate response to changing conditions while providing detailed real-time information about current vehicle states and predictive hazard assessments.
3Loss of information
If current detection methods are used for radio broadcasts, then highway status information is collected, but the detection methods are limited in nature and do not provide information on vehicle operations or occupant status
Solution Approach 1:
The patent employs multi-functional sensors and transceivers that simultaneously perform multiple detection and communication functions. The system collects comprehensive data including vehicle operation status, occupant presence and status, highway conditions, and hazard predictions through integrated sensor arrays. This universal approach consolidates multiple detection capabilities into a unified system that provides extensive information coverage without proportionally increasing complexity.

AI summary
Apparatus according to an embodiment of the present invention includes an advisory system that transmits information regarding the status of the host vehicle to drivers of other vehicles, in particular when the status of the host vehicle presents a hazardous condition to other vehicles. An advisory system may also receive information from other vehicles, and provide an alert to the driver of the host vehicle if a hazard to the host vehicle exists. Methods of providing such information are also described.
