Proactive Collision Protection via Trajectory Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current collision protection systems are inadequate in minimizing the impact of traffic collisions, as they often rely on reactive measures rather than proactive strategies to prevent or mitigate collisions, which can result in property damage and bodily injuries.
Innovation Solution
A collision protection system that utilizes a network of sensors and processors to predict trajectories of vehicles and objects, activating external collision protection devices such as inflatable or thrusting devices at strategic locations and times to prevent or reduce the severity of collisions based on predicted collision events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reactive collision protection measures are used, then the system is simpler to implement, but the collision impact cannot be minimized effectively
Solution Approach 1:
The system performs preliminary actions by predicting collision trajectories and pre-positioning protection devices before the actual collision occurs. The trajectory prediction model forecasts potential collision paths, and protection devices are deployed in advance to the predicted impact locations, transforming reactive protection into proactive prevention.
Solution Approach 2:
The protection system is segmented into multiple independent protection devices positioned at different locations on the vehicle. Each device can be independently activated based on the predicted collision trajectory, allowing selective deployment to specific impact zones rather than deploying a single comprehensive system.
2Measurement precision
If multiple sensors and processors are deployed for trajectory prediction, then collision prediction accuracy improves, but device complexity increases
Solution Approach 1:
The trajectory prediction model serves multiple functions: it predicts collision trajectories, determines impact locations, calculates collision timing, and identifies collision severity. This multi-functional approach consolidates what could be separate systems into a single unified model, reducing overall system complexity while maintaining high prediction accuracy.
3Reliability
If protection devices are activated based on predicted collision events, then collision impact is reduced, but activation timing precision requirements increase
Solution Approach 1:
The system activates protection devices in advance of the actual collision based on predicted collision timing and trajectory. By calculating the time-to-collision from the trajectory prediction model, the system deploys protection devices to the predicted impact location before contact occurs, ensuring optimal protection without requiring millisecond-level precision at the moment of impact.

AI summary
Systems, methods, and non-transitory computer-readable media are provided for collision prevention. In some embodiments, a trajectory of a vehicle with respect to an object can be determined using a trajectory prediction model and sensor data associated with the vehicle and the object. Based on the trajectory, a collision event involving the vehicle and the object can be determined and one or more collision protection devices can be activated.
