Cooperative Vehicle Navigation for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The risk of collisions during lane changes in vehicles, particularly in heavy traffic or when multiple lane changes are necessary, is high due to blind spots and the potential for deviating from intended routes.
Innovation Solution
A vehicle computer system determines trajectories for lane changes and sends instructions to adjacent vehicles to adjust their speed, based on the trajectory, location, and speed of both vehicles, to prevent collisions and ensure safe lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver initiates a lane change without recognizing collision risk, then the lane change operation is simple and quick, but the risk of collision with other vehicles increases
Solution Approach 1:
The system performs preliminary detection of collision risk by monitoring blind spots and trajectory predictions before the lane change is executed. The computer identifies potential collisions in advance and provides warnings to the driver, allowing preventive action to be taken before the harmful event occurs.
Solution Approach 2:
The system continuously monitors the driving environment and provides feedback to the driver about collision risks. By detecting other vehicles' positions and predicting trajectories, the system gives real-time information feedback that enables the driver to adjust behavior and avoid collisions.
2Adaptability or versatility
If multiple lane changes are necessary to leave a multi-lane highway, then the vehicle can reach the intended exit, but the risk of collision increases and the driver may deviate from the intended route
Solution Approach 1:
The system determines the complete sequence of lane changes needed to reach the intended exit in advance. By calculating the optimal trajectory that accounts for multiple lane changes and potential collisions, the system provides a predetermined safe path that reduces the likelihood of route deviation and collision during the maneuver.
Solution Approach 2:
The system continuously monitors whether the vehicle is following the intended route and provides feedback if deviation is detected. This real-time monitoring and feedback mechanism helps maintain route integrity even during complex multi-lane change maneuvers.
3Reliability
If the vehicle computer sends instructions to adjacent vehicles to adjust speed, then collision risk is reduced, but the complexity of the system increases
Solution Approach 1:
The vehicle computer acts as an intermediary that communicates with adjacent vehicles through a communication interface. By sending speed adjustment instructions to neighboring vehicles and receiving their status information, the system coordinates movements to prevent collisions without requiring direct physical interaction or complex control mechanisms.

AI summary
A computer is programmed to determine a trajectory of a first vehicle. The computer is programmed to determine whether a second vehicle blocks the trajectory. Upon such determination, the computer sends an instruction to the second vehicle to adjust the second vehicle speed. The computer is programmed to determine the instruction based on the determined trajectory of the first vehicle, a second vehicle location, and a second vehicle speed.
