Parking Steering Assistant Function Grouping by Ignition State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems for motor vehicles often have non-ergonomic user interfaces and are overly complex, making it difficult for drivers to interact effectively with the assistance systems during parking and exit maneuvers.
Innovation Solution
A method for assisted parking that categorizes parking assistance functions into two groups based on the ignition switch status and distance traveled, using a sensor system to determine the surroundings and classify parking spaces, allowing for automatic selection of appropriate functions and simplifying the operation through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If parking assistance functions are manually selected through a complex user interface, then the system can provide comprehensive parking support, but the operation becomes overly complex and non-ergonomic
Solution Approach 1:
The parking assistance system automatically determines the current parking situation using sensor data and travel direction information, then autonomously selects the appropriate assistance function without requiring manual driver input. The system serves itself by automatically configuring the assistance level based on detected parking space geometry and vehicle state.
Solution Approach 2:
The system pre-categorizes parking assistance functions into two groups (first group for initial parking maneuvers, second group for final alignment) based on anticipated parking scenarios. This preliminary organization allows the system to quickly present relevant options rather than requiring drivers to navigate through all possible functions.
2Adaptability or versatility
If the system provides comprehensive parking assistance functions, then parking support is enhanced, but the device complexity increases
Solution Approach 1:
The parking assistance functions are segmented into two distinct groups: the first group handles initial parking maneuvers (approach and entry), while the second group handles final alignment and positioning. This segmentation allows the system to manage complexity by organizing functions into logical phases rather than presenting a monolithic set of options.
Solution Approach 2:
The system dynamically transitions between different assistance function groups based on real-time sensor data and vehicle state. The categorization between first and second group functions is not fixed but adapts according to the parking maneuver progress, allowing the system to provide comprehensive support while maintaining manageable complexity through dynamic reconfiguration.
3Productivity
If automatic parking mode is activated without driver confirmation, then the parking process is streamlined, but safety risks increase if obstacles are misidentified
Solution Approach 1:
The system continuously monitors sensor data during the parking maneuver and provides feedback to verify obstacle-free conditions before and during automatic operation. The sensor system actively scans the environment throughout the process, allowing the system to detect obstacles that may have been missed initially and to confirm safe operation before proceeding with automatic parking.

AI summary
In the method and the device for selecting a parking assistance function from a predefined multiplicity of parking assistance functions of a parking steering assistant by means of an input element of the parking steering assistant of a motor vehicle, the parking assistance functions are arranged in two groups, wherein the first group comprises the functions which relate to parking of the vehicle and the second group comprises functions which relate to exiting a parking space by the vehicle, and a selection is made between the two function groups as a function of the ignition switch state and a distance travelled by the vehicle, as a result of which the method differentiates automatically between parking functions and parking space exiting functions.
