Vehicle Blind-Spot Camera Warning During Turning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large vehicles, such as buses and trucks, have blind spots that obstruct the driver's view of potential obstacles, particularly when turning, leading to increased risk of collisions with pedestrians or cyclists in urban environments.
Innovation Solution
A vehicle-mounted camera system that adjusts its field of view based on the vehicle's yaw to detect and warn the driver of obstacles in blind spots, using multiple cameras to process image frames and provide audible or visual warnings, and potentially control the vehicle's steering or braking to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle turns, then the driver's view of the road changes, but blind spots increase and obstruct the view of potential obstacles
Solution Approach 1:
The patent introduces cameras as intermediary devices mounted on the vehicle to capture images of areas not visible to the driver. These cameras act as mediators between the driver and blind spot areas, transmitting visual information through displays or audio outputs when obstacles are detected during turning maneuvers.
Solution Approach 2:
The patent replaces the mechanical limitation of the driver's physical view with an electronic detection system. Instead of relying on the driver's line of sight, the system uses cameras and processors to detect obstacles in blind spots and provides warnings, substituting electronic sensing for mechanical visual observation.
2Reliability
If the field of view is expanded to cover blind spots, then obstacle detection capability improves, but the system complexity increases
Solution Approach 1:
The patent divides the detection task into segments by using multiple cameras positioned at different locations on the vehicle. Each camera covers specific zones, and the processor selectively activates and processes images from relevant cameras based on vehicle state (e.g., turning left or right), reducing overall system complexity while maintaining comprehensive coverage.
Solution Approach 2:
The patent implements dynamic camera activation where the system selectively turns on specific cameras based on the vehicle's operational state. During straight driving, fewer cameras are active compared to when turning, where additional cameras are activated to cover blind spots in the turning direction, optimizing resource usage and reducing complexity.

AI summary
Systems and methods are provided for processing reports received from vehicles. A processing device perform operations comprising receiving a first report generated by a first vehicle, the first report generated by the first vehicle for a first hazard detected by the first vehicle; receiving a second report generated by a second vehicle, the second report generated by the second vehicle for a second hazard detected by the second vehicle; analyzing the first report and the second report to make a determination that the first report and the second report identify a related hazard; aggregating the first report and the second report into a consolidated report based on the determination that the first report and the second report identify a related hazard; and generating a map, the map indicating a location of the related hazard based on the consolidated report.
