Impaired Driver Path Prediction for Vehicle Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle alert systems fail to provide warnings or gather information about impaired drivers, which can lead to dangerous situations and accidents, and do not effectively respond to the erratic behavior of such drivers.
Innovation Solution
A system and method that uses sensors to detect impaired drivers, predicts their paths, and provides alerts or automatically adjusts vehicle routes to avoid hazardous intersections, using information gathered from a network of vehicles to enhance driving safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vehicle alert systems are used, then basic information about conditions directly associated with the vehicle's current location is provided, but warnings about impaired drivers and dangerous situations are not conveyed
Solution Approach 1:
The patent combines multiple information sources including sensor data from the host vehicle, crowd-sourced data from other vehicles, and predictive analytics into a unified alert system. This merging of diverse data streams enables comprehensive detection of impaired drivers and prediction of dangerous behaviors, resolving the information gap in conventional systems
Solution Approach 2:
The system performs preliminary analysis of driving patterns and predicts potential dangerous actions before they occur. By analyzing erratic driving behaviors and predicting future positions and actions of potentially impaired drivers, the system provides advance warning to drivers, enabling them to take preventive measures before accidents occur
2Ease of operation
If conventional alert systems are used, then basic vehicle condition information is available, but the ability to respond to erratic behavior of impaired drivers is insufficient
Solution Approach 1:
The system implements continuous feedback loops where sensor data is constantly monitored, analyzed, and used to update predictions and alerts. The system provides real-time feedback to the driver about detected dangerous situations and predicted actions of impaired drivers, enabling informed decision-making and appropriate response
Solution Approach 2:
The alert system dynamically adjusts its behavior based on detected driving patterns and predicted risks. The system adapts its alerting strategy, prediction models, and response recommendations in real-time based on the evolving situation, making it more effective at guiding driver responses to erratic behaviors
3Measurement precision
If information gathering from multiple vehicles is implemented, then predictive analysis of impaired driver behavior is improved, but system complexity increases
Solution Approach 1:
The system employs universal data collection protocols and standardized processing algorithms that can handle multiple data sources (sensors, crowd-sourced information, predictive models) through a unified architecture. This multi-functional approach enables precise prediction analysis while managing system complexity through standardized interfaces and modular design

AI summary
Methods and systems for detecting and responding to impaired drivers are disclosed. The methods intelligently alert and route a user driver's vehicle to improve driving safety based on a predicted path of an impaired driver. The method shares data collected by vehicles in an area to determine which that a vehicle has an impaired driver. The method associates cones of certainty with such a vehicle to establish where the vehicle is likely to travel in the future. If the system determines there is a likelihood of accident based on a proximity to these cones of certainty, an alert can be presented to a user driver of a proximate vehicle. The method also generates routes that avoid or limit the user driver's exposure to the impaired driver's vehicle, such as by suggesting detours or automatically controlling the user driver's vehicle to avoid the path of the impaired driver.
