Steering Grip Detection for Intuitive Parking Assist Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking assistance systems require non-intuitive and potentially error-prone manual input to select between different parking assistance functions, posing a safety risk and reducing operating comfort for drivers.
Innovation Solution
A method for automatically selecting between a first and second parking assistance function based on the driver's gripping state of the steering handle, using sensor devices to detect the gripping state and control units to activate the corresponding assistance function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual input is used to select parking assistance functions, then the driver can choose from multiple functions, but the operating comfort decreases and safety risks increase due to non-intuitive controls and driver distraction
Solution Approach 1:
The system automatically detects the driver's gripping state and autonomously selects the appropriate parking assistance function without requiring manual input. The sensor device monitors whether the driver is gripping the steering handle, and the control unit automatically activates the corresponding function (manual steering assistance or automated parking), making the system self-selecting based on driver behavior.
Solution Approach 2:
The patent replaces manual mechanical input (driver pressing buttons or touching screens) with an automatic sensing system. Sensor devices detect the gripping state mechanically/physiologically, and the control unit processes this information to automatically select functions, substituting the manual selection mechanism with an automated detection-and-response system.
2Adaptability or versatility
If manual input is used to select parking assistance functions, then the driver can choose from multiple functions, but operational safety decreases due to driver distraction from searching for input options
Solution Approach 1:
The system performs automatic function selection based on driver behavior detection, eliminating the need for the driver to search for and manually input selection commands. The control unit autonomously determines which parking assistance function to activate based on sensor data about gripping state, keeping the driver's attention on the road.
Solution Approach 2:
The sensor device continuously monitors the gripping state in advance, and the control unit is pre-programmed with selection logic that automatically activates the appropriate function before the driver would need to request it. This preliminary detection and automatic response prevents distraction by eliminating the selection step entirely.
3Adaptability or versatility
If manual input is used to select parking assistance functions, then the driver can choose from multiple functions, but the potential for errors increases due to non-intuitive controls
Solution Approach 1:
The system eliminates manual selection input entirely by automatically detecting driver intent through gripping state and selecting the appropriate function. This removes the source of selection errors (non-intuitive controls) while preserving full functionality access through automatic activation based on detected driver behavior.
