Post-Parking Sensor Data Analysis for Driver Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems provide real-time feedback during the parking process, which can be distracting and increase safety risks, and they lack the ability to analyze and optimize parking behavior post-parking for improved efficiency and reduced material consumption.
Innovation Solution
A method where sensor signals from the parking process are stored and evaluated separately from the vehicle's control unit, allowing for post-parking analysis and optimization instructions to be provided to the user in a non-distracting manner, using various sensors like ultrasonic, radar, and LIDAR, with data transfer via USB or radio links for detailed feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If real-time feedback is provided during the parking process, then the driver receives immediate guidance, but the driver becomes distracted and safety risks increase
Solution Approach 1:
The system performs the evaluation and generates optimization instructions in advance, before the driver needs them. The parking process is recorded and evaluated afterwards, allowing the driver to receive guidance without real-time distraction while still benefiting from pre-computed optimization hints
Solution Approach 2:
The evaluation function is extracted from the real-time control loop and performed separately after parking completion. By separating the recording/evaluation phases from the actual parking maneuver, the system provides guidance without creating driver distraction during the critical parking operation
2Object-affected harmful factors
If parking optimization analysis is performed after parking, then safety risks are reduced, but the ability to provide immediate feedback is lost
Solution Approach 1:
The system implements feedback by storing sensor signals during parking and subsequently evaluating them to generate optimization instructions. This feedback loop allows the driver to learn from analyzed parking behavior while maintaining safety, as the feedback is provided when the vehicle is stationary and the driver is not distracted
Solution Approach 2:
The system creates a digital copy of the parking process through sensor signal recording. This copy can be analyzed without affecting the actual parking maneuver, allowing delayed evaluation and optimization instruction generation that does not compromise real-time safety
3Productivity
If sensor data is processed in real-time during parking, then immediate optimization is possible, but system complexity and computational load increase
Solution Approach 1:
The system performs data acquisition and storage during parking, then conducts the complex evaluation and optimization analysis afterwards. This preliminary recording approach separates the simple real-time data collection from the complex post-processing, reducing the computational burden on the control unit during the actual parking maneuver
Solution Approach 2:
The complex evaluation and optimization functions are extracted from the real-time control unit operations and performed separately. By removing the heavy computational tasks from the in-vehicle control system and performing them afterwards, the patent reduces control unit complexity while still achieving parking optimization
