Driver Assistance System for Autonomous Parking Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle parking systems often fail to utilize small parking spaces effectively due to insufficient exit space for drivers or passengers, leading to prolonged search times and suboptimal space utilization.
Innovation Solution
A method and driver assistance system that allows vehicles to be stopped in front of parking spaces using sensor systems for dimension comparison, enabling autonomous parking and exit options, including remote control, to facilitate parking in tight spaces and prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle is parked in a small parking space to maximize space utilization, then the space utilization is improved, but the driver cannot exit the vehicle safely
Solution Approach 1:
The system performs preliminary actions by providing an exit option before the parking maneuver is completed. The driver is offered the possibility to exit the vehicle during the parking process, and if selected, the vehicle autonomously completes the parking maneuver after the driver has exited. This resolves the contradiction by ensuring driver safety is prioritized while still enabling use of small parking spaces.
2Reliability
If the driver searches for larger parking spaces to ensure exit capability, then the driver exit safety is improved, but the search time is prolonged and space utilization is reduced
Solution Approach 1:
The system enables self-service by allowing the driver to exit the vehicle autonomously while the vehicle completes the parking maneuver on its own. The driver does not need to search for larger spaces or manually maneuver the vehicle to create exit space, as the system automatically handles the parking completion after the driver has exited. This eliminates the time loss associated with searching for larger parking spaces.
3Reliability
If the vehicle is stopped in front of the parking space to allow driver exit, then the driver exit safety is improved, but the parking space utilization is reduced
Solution Approach 1:
The system performs the driver exit action preliminarily, before the vehicle completes the parking maneuver. The driver exits the vehicle while it is still in front of the parking space, and then the vehicle autonomously parks itself in the space. This eliminates the need to stop the vehicle to allow driver exit, thereby maximizing parking space utilization while ensuring driver safety.
