Vehicle Control System Adjusting Stop Location for Driver Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicle control systems often stop vehicles at locations where the driver cannot optimally see traffic signals or other points of interest, making it difficult for the driver to monitor conditions and make decisions, such as right turns on red.
Innovation Solution
A vehicle control system that includes a sensing system to detect the driver's visual condition and a controller to adjust the stopping location based on the driver's field of view, ensuring that relevant points of interest are within the driver's view by communicating with imaging devices, navigation systems, and remote vehicles through a wireless network.

Engineering Contradiction Analysis
1Reliability
If the autonomous vehicle control system stops the vehicle based on camera field of view, then the vehicle can stop at appropriate locations for autonomous operation, but the driver cannot optimally see traffic signals or points of interest
Solution Approach 1:
The system dynamically adjusts the stopping location based on real-time detection of driver visual conditions. The controller modifies the predetermined stopping location to ensure points of interest fall within the driver's field of view, making the stopping behavior adaptive rather than fixed.
Solution Approach 2:
The sensing system continuously monitors driver visual conditions and provides feedback to the controller. The controller uses this feedback to adjust the stopping location, creating a closed-loop system that balances autonomous operation requirements with driver visibility needs.
2Measurement precision
If the vehicle stops at a location optimized for autonomous operation, then the camera system can effectively monitor surroundings, but the driver's field of view of traffic signals is blocked
Solution Approach 1:
The system dynamically determines stopping locations by considering both camera field of view requirements and driver visual conditions. The controller adjusts the stopping location in real-time to satisfy both detection accuracy and information accessibility requirements.
Solution Approach 2:
The system changes the stopping location parameter based on detected driver visual conditions. By modifying this key parameter, the system ensures that points of interest remain visible to the driver while maintaining adequate stopping distance for safe autonomous operation.

AI summary
A vehicle control system and method employs a sensing system and a controller. The sensing system is disposed on a host vehicle and configured to sense a visual condition of a driver of the host vehicle. The controller is configured to control an autonomous vehicle control system on board the host vehicle to stop the host vehicle at a stopping location based on the visual condition and at least one point of interest external to the host vehicle.
