Object Detection System Dynamic Transition Period Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection systems face challenges in smoothly switching between different detection methods, such as stereo cameras and mono cameras, leading to potential collisions due to sudden changes in calculated inter-vehicle distances, especially at high relative speeds, and result in uncomfortable vehicle control when the transition period is fixed.
Innovation Solution
An object detection system that acquires and identifies vehicle information using multiple detecting means, selects accurate data based on detection accuracy, and adjusts the transition period according to relative speed and distance, ensuring seamless switching and accurate vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed transition period is used to switch between vehicle information from different detecting means, then the vehicle control becomes smoother and less uncomfortable for the driver, but the system may not respond quickly enough to detected objects when relative speed is high, potentially causing collision
Solution Approach 1:
The patent applies dynamics by making the transition period variable rather than fixed. The control period is dynamically adjusted based on the relative speed between the subject vehicle and detected object. When relative speed is high, the transition period is shortened to enable faster response; when relative speed is low, the transition period is extended to maintain smooth control. This dynamic adjustment resolves the contradiction between control smoothness and response speed.
2Ease of operation
If the transition period is extended to ensure smooth vehicle control switching, then driver comfort improves, but the system experiences delay in vehicle control when the distance to detected object is short, potentially causing collision
Solution Approach 1:
The patent dynamically adjusts the transition period based on the distance to the detected object. When the distance is short, the transition period is automatically shortened to prevent control delays that could lead to collision. When the distance is long, the transition period can be extended to maintain smooth control transitions. This dynamic adaptation resolves the contradiction between control smoothness and response time.
3Device complexity
If a fixed transition period is used for switching vehicle information, then the switching process is simple to implement, but the system cannot adapt to different driving conditions such as varying relative speeds and distances
Solution Approach 1:
The patent implements dynamic adjustment of the transition period based on real-time driving conditions including relative speed and distance to detected objects. The control period is automatically modified according to these parameters, enabling the system to adapt to various driving scenarios such as high-speed overtaking, low-speed following, or emergency situations. This dynamic approach enhances adaptability while maintaining reasonable system complexity through rule-based adjustment.

AI summary
An object detection system including multiple detecting means identifies other-vehicle information data acquired by using the multiple detecting means, determines whether or not the other-vehicle information data acquired by using the multiple detecting means 105 and 107 are of the same vehicle to output the other-vehicle information data that can be applied to various control applications when the other-vehicle information data determined to be of the same vehicle are switched, selects either of the multiple other-vehicle information data determined to be of the same vehicle according to the other-vehicle information detecting accuracies of the detecting means 105 and 107, and switches the selected other-vehicle information data to another other-vehicle information in a transition period based on the relative speed and the relative position from the other vehicle.
