Vehicle Touch Interface Control for Adjacent Input Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch-sensitive operating elements in vehicles can be unintentionally operated due to vibrations or spatial proximity, leading to unintended actuation of functions, which compromises operating safety and convenience.
Innovation Solution
A vehicle operating system with a control unit and touch-sensitive user interface that registers user selections and blocks functions of adjacent operating elements, preventing unintentional triggering by defining pixel regions and using a bus system to manage inputs, thereby increasing safety and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If numerous touch-sensitive operating elements are arranged in close spatial proximity to provide comprehensive vehicle functions, then the functionality and versatility of the control system is improved, but the risk of unintentional operation due to vibrations or accidental touching increases
Solution Approach 1:
The control unit preemptively blocks functions of adjacent operating elements before unintentional operation can occur. When a user selects an operating element, the system proactively disables neighboring functions that could be accidentally triggered, preventing harmful effects before they happen.
Solution Approach 2:
The control unit acts as an intermediary between the touch-sensitive operating elements and the vehicle functions. It mediates by selectively blocking signal transmission to adjacent operating elements when a selection is detected, preventing direct unintentional activation while maintaining the physical arrangement of elements.
2Reliability
If the control unit blocks functions of adjacent operating elements during selection, then unintentional operation is prevented and operating safety is improved, but the complexity of the control software increases
Solution Approach 1:
The blocking function is applied locally only to adjacent operating elements surrounding the selected element, rather than globally to all elements. This localized approach minimizes the complexity increase by limiting the scope of control logic to only those elements that pose a risk of unintentional operation.
Solution Approach 2:
The control system segments the operating elements into selected and adjacent groups, applying different control logic to each segment. The selected element receives full functionality while adjacent elements are blocked, creating a segmented control strategy that manages complexity through spatial division.
3Ease of operation
If touch-sensitive operating elements are used to provide comprehensive vehicle control functions, then ease of operation and user convenience are improved, but unintentional actuation due to vibrations or spatial proximity compromises operating safety
Solution Approach 1:
The system applies preliminary anti-action by blocking adjacent functions before unintentional actuation can occur. When an operating element is selected, the control unit preemptively disables neighboring elements that could be accidentally triggered by vibrations or hand rest, counteracting potential harmful effects before they manifest.

AI summary
System including one or more touch-sensitive control surfaces on which control elements, which are arranged next to each other, are displayed. Using a control device with controller software, the control elements can determine amongst themselves via the controller software, when a respective control element should be active or deactivated when touched.
