Vehicle Adjusting Part Sensor Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle adjustment systems lack user awareness of sensor system measuring uncertainties, leading to potential collisions and damage due to incomplete obstacle detection reliability, as users assume autonomous operation without feedback on measurement uncertainties.
Innovation Solution
A method and device that generate a status indicator for sensor devices, signaling different operating states to users through visual, acoustic, and haptic means, allowing users to intervene during extraneous-force-activated adjustments, by assessing measurement certainty and adapting signaling based on standard deviations, historical data, and calibration tests.

Engineering Contradiction Analysis
1Extent of automation
If the adjusting device operates autonomously with sensor-based obstacle detection, then the adjustment movement can be controlled automatically, but the user lacks awareness of sensor measuring uncertainties leading to potential collisions
Solution Approach 1:
The system implements feedback by generating status indicators that communicate sensor operating states and measurement uncertainties to the user. The electronic control system evaluates sensor signals and produces visual, acoustic, or haptic feedback signals that inform users about the reliability of obstacle detection, enabling them to make informed decisions about whether to intervene in the adjustment process.
2Reliability
If the system provides comprehensive status information about sensor operating states, then user awareness and safety are improved, but the device complexity increases
Solution Approach 1:
The system segments the status information into distinct operating states (first operating state indicating reliable detection, second operating state indicating unreliable detection). The electronic control system evaluates sensor signals against predefined criteria and assigns discrete status indicators, simplifying the communication of complex sensor reliability data into manageable, easily interpretable categories for the user.
3Measurement precision
If the adjusting device continuously monitors sensor signals and generates status indicators, then measurement reliability is improved, but the energy consumption increases
Solution Approach 1:
The system employs periodic evaluation of sensor signals rather than continuous monitoring. The electronic control system assesses sensor operating states at defined intervals or at specific moments during the adjustment process, generating status indicators only when necessary. This periodic approach maintains measurement precision while significantly reducing energy consumption compared to continuous monitoring.

AI summary
A method for adjusting an adjusting part on a vehicle, wherein a possible obstacle in an adjustment path of the adjusting part which is to be adjusted can be detected by means of at least one sensor device, in order to block, stop and/or reverse an adjustment movement of the adjusting part. There is provision that at least one status indicator for the at least one sensor device is generated electronically, by means of which data indicator at least two different first and second operating states of the sensor device can be signaled, and for the adjustment movement of the adjusting part at least one current status information item of at least two different status information items relating to the current operating state of the at least one sensor device is signaled in accordance with the status indicator, in order to be perceived by a user.
