Network-Based Vehicle Warning System for Extended Detection Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver assistance systems, relying on locally mounted sensors, are ineffective in providing advance warnings beyond a short range and may fail during adverse weather conditions, particularly for large vehicles like tractor-trailers, leading to potential collisions due to inadequate stopping distances.
Innovation Solution
An advanced warning system that utilizes a network device to gather parameters from fleet vehicles to detect traffic conditions and transmit warnings to other vehicles within a proximity threshold, allowing for remote override of driving capabilities if the driver fails to respond, thereby extending the warning range and ensuring safer distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sensor systems (radar, laser, camera) are mounted locally on the vehicle, then the system can detect objects in the immediate vicinity, but the warning range is limited to a short distance and the system fails during adverse weather conditions
Solution Approach 1:
The patent combines multiple information sources including local sensors (radar, laser, camera), remote sensors mounted on other vehicles, and communication networks to create a comprehensive monitoring system. This merging of distributed sensing resources extends the effective warning range and maintains reliability during adverse weather conditions where individual sensors may fail.
Solution Approach 2:
The system introduces communication networks and remote sensing platforms as intermediaries to transmit environmental information from distant locations to the vehicle. This intermediary layer allows the vehicle to receive early warnings about hazards beyond the range of its own sensors, compensating for the limited detection capability of local sensors.
2Loss of time
If the effective range of conventional sensor systems is extended, then early warning capability is improved, but the system complexity and cost increase
Solution Approach 1:
The patent creates a multi-functional system where a single integrated platform performs multiple functions: local sensing, remote sensing reception, data processing, warning generation, and communication. This universal system approach extends warning time without proportionally increasing complexity, as the same infrastructure serves multiple purposes.
Solution Approach 2:
The system performs preliminary detection and warning actions at distances beyond the vehicle's immediate sensor range by utilizing remote sensors and communication networks. This preliminary action provides early warning time while the vehicle is still far from hazards, allowing drivers to take preventive measures before entering dangerous zones.
3Object-affected harmful factors
If remote override capability is added to the warning system, then collision prevention is improved, but the driver's operational autonomy is reduced
Solution Approach 1:
The system applies preliminary anti-action by providing advance warnings to the driver before hazardous situations develop. The remote override capability serves as a backup preliminary protective measure that activates only when the driver fails to respond to initial warnings, thereby preventing collisions while respecting driver autonomy during normal operation.
Solution Approach 2:
The system implements a feedback mechanism where the driver's response to warnings is monitored. If the driver takes appropriate corrective action, the override function remains inactive. If the driver fails to respond or the situation escalates beyond safe thresholds, the system automatically activates remote override controls to prevent collisions, thus balancing autonomy with safety.

AI summary
Aspects of the present disclosure generally relate to one or more systems, methods, and/or devices for an advanced warning system that alerts drivers of potential upcoming traffic conditions (e.g., accidents or traffic slowdowns) based on active monitoring of vehicle parameters (e.g., speed, braking, air bag deployment, etc.) associated with other vehicles traveling ahead in the same direction. Thus, in some aspects, the advanced warning system may receive, at a network device (e.g., network management center (NMC)), one or more parameters from a first mobile computing platform (MCP) associated with a first vehicle and determine, at the network device, whether a traffic condition has developed on a stretch of highway based on the one or more parameters.
