Vehicle Sensor Capture Region Control for Moving Component Exclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing environment capturing sensor systems struggle to adapt their capture regions to dynamically changing vehicle components, leading to potential misidentification of these components as obstacles or objects in the vehicle's environment.
Innovation Solution
A method and control device that dynamically adjust the capture region of an environment capturing sensor system by defining a restricted capture region by omitting sub-regions of both static and dynamic vehicle components' locations, using control signals to change the position of vehicle components relative to the sensor system and filter out measurement data from these regions.

Engineering Contradiction Analysis
1Measurement precision
If the capture region of the environment capturing sensor system is expanded to cover the entire surrounding area, then the sensor system can detect more environmental objects, but vehicle components may be misidentified as obstacles leading to false detections
Solution Approach 1:
The patent extracts and removes the vehicle component regions from the capture region by defining a restricted capture region that excludes areas where vehicle components are located. This is achieved by determining the location of vehicle components and subtracting these regions from the overall capture region, thereby preventing misidentification of vehicle components as environmental obstacles while maintaining detection of actual environmental objects
Solution Approach 2:
The patent segments the capture region into multiple zones: the full capture region, vehicle component regions, and the restricted capture region. By dividing the space and applying different processing rules to different segments, the system can handle vehicle components and environmental objects differently, ensuring accurate detection without false positives from vehicle parts
2Reliability
If the capture region is restricted to exclude vehicle component locations, then false detection of vehicle components is prevented, but the capture region may exclude relevant environmental objects
Solution Approach 1:
The patent implements a dynamic approach where the restricted capture region is continuously updated based on the real-time position of vehicle components. As vehicle components move, their location regions are recalculated and the restricted capture region is adjusted accordingly. This dynamic adaptation ensures that the capture region remains optimized to exclude vehicle components while maintaining coverage of environmental objects throughout the vehicle's operation

AI summary
A method for controlling an environment capturing sensor system which is arranged on a vehicle, including reading a control signal for controlling a vehicle component of the vehicle, wherein the vehicle is configured to be controlled such that the position of the vehicle component relative to the environment capturing sensor system changes. The method further includes defining a dynamic location region of the vehicle component within an outer contour of the vehicle depending on the control signal reading and defining a restricted capture region by omitting at least a sub region of the defined dynamic location region of the vehicle component from a capture region of the environment capturing sensor system. The method further includes outputting a control signal for capturing the vehicle environment in the defined restricted capture region.
