Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance technologies face challenges in providing precise and simplified parking assistance, especially in difficult environmental conditions and for perpendicular parking spaces, where the vehicle's longitudinal axis is aligned transversely to the parking space.
Innovation Solution
A device with a selection device connected to an evaluation unit that determines multiple parking trajectories and allows the driver to select the most suitable one based on real-time conditions, using a sensor arrangement and clothoids for easy navigation, with options for manual or automatic steering and braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single parking trajectory is calculated based on geometric measurement, then the parking process can be automated, but the system cannot adapt to difficult environmental conditions or driver preferences
Solution Approach 1:
The system dynamically generates multiple parking trajectories based on real-time sensor measurements and automatically selects the most suitable trajectory according to current environmental conditions, making the system adaptive without requiring complex manual intervention
Solution Approach 2:
The evaluation unit autonomously evaluates multiple calculated trajectories and selects the optimal one without driver input, while still providing the option for manual selection, thereby adapting to conditions automatically while maintaining simplicity
2Ease of operation
If the vehicle is automatically steered into the parking space along a calculated trajectory, then the ease of operation is improved, but the system may collide with obstacles or fail in difficult environmental conditions
Solution Approach 1:
The system continuously monitors the parking process using sensor arrangements and compares actual vehicle position with the calculated trajectory, enabling real-time corrections to maintain reliability while keeping operation simple
Solution Approach 2:
Multiple trajectories are pre-calculated considering various obstacles and environmental conditions before the parking maneuver begins, allowing the system to anticipate and avoid potential collision scenarios while maintaining automated operation
3Adaptability or versatility
If multiple parking trajectories are determined and displayed for driver selection, then the adaptability to different conditions is improved, but the device complexity increases
Solution Approach 1:
The parking space and surrounding area are segmented into multiple discrete trajectory options, each optimized for specific conditions, allowing the driver to select from clearly defined alternatives without overwhelming complexity
Solution Approach 2:
The evaluation unit acts as an intermediary that automatically processes multiple trajectory calculations and presents them in a simplified format to the driver, reducing the perceived complexity while maintaining adaptability
