Vehicle Door Adjustment System with Adaptive Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door adjustment systems face challenges in reliably distinguishing between user presence and obstacles during operation, leading to potential prevention of desired adjustments due to false obstacle recognition.
Innovation Solution
A system that employs different recognition areas and operating modes for collision protection monitoring, using a first recognition area when an operating command is received near the vehicle door to exclude user presence and a larger second recognition area when the command is received from a distant area, allowing for safe adjustment while preventing false obstacle detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single recognition area is used for collision protection monitoring, then obstacle detection is simplified, but user presence is incorrectly identified as an obstacle
Solution Approach 1:
The recognition area is segmented into a first recognition area (when operating device is activated in near area) and a second recognition area (when operating device is activated in distant area). The first recognition area excludes the area where the user is present when activating the operating device, while the second recognition area includes a larger area for comprehensive obstacle detection when the user is not present. This segmentation resolves the contradiction by preventing false obstacle detection of users while maintaining reliable obstacle detection.
2Reliability
If the recognition area is expanded to detect all obstacles, then collision protection is improved, but user presence in the adjustment path is falsely recognized as an obstacle
Solution Approach 1:
The recognition area is made dynamic and adaptive based on the operating mode. When the operating device is activated in the near area, the system switches to the first operating mode with the first recognition area that excludes the user presence area. When the operating device is activated in the distant area, the system switches to the second operating mode with the second recognition area that includes the full detection range. This dynamic adaptation resolves the contradiction by adjusting the recognition area according to the operational context.
3Reliability
If obstacle detection is performed in the area where users operate the door, then collision protection is enhanced, but desired door adjustments are prevented due to false obstacle recognition
Solution Approach 1:
Different areas within the recognition zone are assigned different qualities or functions. The first recognition area specifically excludes the area where the user is present when activating the operating device, creating a local exception to obstacle detection in that specific zone. This local quality differentiation allows the system to maintain collision protection in other areas while permitting door adjustment operations in the user presence area.

AI summary
A system for adjusting a vehicle door relative to a vehicle body including an adjusting device, a control device for controlling the adjusting device. The control device is configured to receive an operating command and control the adjusting device based on receiving the operating command, and a sensor device for detecting an object. The control device is configured to evaluate for the purpose of collision protection monitoring whether an operating command is received in a near area relative to the vehicle door via an operating device. For collision protection monitoring, the control device is configured to use a first recognition area in a first operating mode upon receiving an operating command via an operating device in the near area, and in a second operating mode to use a second recognition area different from the first recognition area when an operating command is not received in the near area.
