Rotary Push-Button Interface for Safe Drive Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a central, efficient method for quickly activating or deactivating driver assistance systems or drive modes during autonomous driving, complicating operations and impacting safety and user friendliness.
Innovation Solution
A rotating push-button interface allows for the selection and activation/deactivation of driver assistance systems or drive modes by rotation and confirmation with a press, enabling simple and quick switching without unintended activations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate hardware buttons are used to activate or deactivate driver assistance systems, then each system can be controlled individually, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple separate control functions into a single rotary push-button interface. This central control element integrates selection and activation/deactivation functions, eliminating the need for multiple separate hardware buttons while simplifying the user interaction process.
Solution Approach 2:
The rotary push-button serves multiple functions: it can select different driver assistance systems through rotation and activate or deactivate the selected system through pressing. This multi-functional design reduces the total number of control elements needed while maintaining comprehensive system control capability.
2Productivity
If multiple separate controls are provided for different driver assistance systems, then each system can be independently controlled, but the operation time increases and driving safety is compromised
Solution Approach 1:
By merging the control functions into a single rotary push-button, the system enables rapid switching between different driver assistance systems and their activation/deactivation states. This reduces the time required for control operations while maintaining safety through a unified, reliable interface.
3Ease of operation
If a simple button press is used for activation, then the operation is quick, but unintended activations may occur during autonomous driving
Solution Approach 1:
The control operation is segmented into two distinct actions: rotation for system selection and pressing for activation/deactivation. This segmentation requires a deliberate two-step process, reducing the likelihood of unintended activations while maintaining operational speed through intuitive motion sequences.
Solution Approach 2:
The rotary push-button introduces dynamic control where the selection state changes through rotation but only becomes active through a deliberate pressing action. This dynamic interaction pattern helps prevent unintended activations by requiring conscious user confirmation through the pressing motion.

AI summary
An adjustment device for activating or deactivating at least one of a driver assistance system and a driver assistance mode for autonomous driving in a vehicle may include a push-button. The push-button may be configured to select at least one of the driver assistance system and the driver assistance mode upon rotation of the push-button. The push button may also be configured to activate or deactivate at least one of the driver assistance system and the driver assistance mode upon linear movement of the push-button due to a pushing action by an operator.
