Steering Wheel Touch Input Control for Erroneous Contact Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices fail to distinguish between intended and erroneous inputs when a user operates a controller with an input section, such as a touch switch on a steering wheel, leading to unintended interactions and potential safety issues during vehicle operation.
Innovation Solution
A control device that includes an input detection section and an erroneous input determination section, which determines whether an input is erroneous based on the region detected in the input section, allowing for the setting of an erroneous input detection region, including the vicinity of the border, to differentiate between intended and erroneous inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the steering wheel is equipped with a touch switch to enable input operations, then the ease of operation is improved, but erroneous input occurs when the user turns the steering wheel and unintentionally contacts the touch switch
Solution Approach 1:
The touch switch surface is segmented into multiple independent detection regions, each capable of detecting touch position and pressure independently. This segmentation allows the system to distinguish between intentional touches on specific functional areas and unintentional contacts on border regions, resolving the contradiction between ease of operation and input accuracy.
Solution Approach 2:
Different regions of the touch switch are assigned different functions and sensitivity levels. The central region is designated for intentional input operations with full functionality, while border regions are marked as erroneous input detection zones with reduced or nullified functionality. This local differentiation allows the system to maintain ease of operation in functional areas while preventing erroneous inputs at borders.
2Ease of operation
If the touch switch responds to all contacts to ensure no intended input is missed, then the ease of operation is improved, but unintended input cannot be distinguished from intended input
Solution Approach 1:
The system provides feedback by analyzing touch characteristics such as position, pressure, and duration to determine input intent. When a touch occurs in a border region or exhibits characteristics of unintentional contact, the system provides feedback by nullifying the input or prompting the user for confirmation, thereby maintaining responsiveness to valid inputs while filtering out erroneous ones.
Solution Approach 2:
The touch switch system dynamically adjusts its response based on real-time analysis of touch characteristics and context. The system can change its sensitivity and response behavior depending on whether the touch appears intentional or unintentional, allowing it to maintain high responsiveness to valid inputs while dynamically suppressing erroneous inputs.
