Vehicle Parking Assistance System with Dynamic Target Redetermination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems fail to successfully complete a parking process if an obstacle prevents the vehicle from reaching the originally planned position within a parking space, often resulting in endless attempts to reach an unattainable target position.
Innovation Solution
A method and system that automatically determine a target position for a vehicle within a parking space, activate steering intervention, sense vehicle states that prevent reaching the target, and redetermine the target position as needed, allowing the parking process to continue with updated coordinates, avoiding obstacles and ensuring successful parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking assistance system continuously attempts to reach the original target position, then the system maintains its original parking plan, but the parking process becomes endless and unsuccessful when an obstacle blocks the target position
Solution Approach 1:
The system continuously monitors the vehicle state during the parking process and uses this feedback to detect when the original target position becomes unattainable. When an obstacle is detected or the vehicle state indicates the target cannot be reached, the system responds by redetermining a new target position, thereby converting endless failed attempts into successful parking completion.
2Difficulty of detecting and measuring
If the system uses sensors to detect obstacles in the surroundings, then the system can identify external obstacles, but it cannot detect vehicle states that prevent reaching the target position
Solution Approach 1:
The parking assistance system performs multiple functions: it not only detects external obstacles using sensors but also monitors internal vehicle states (position, orientation, gear changes) to comprehensively determine whether the target position is reachable. This multi-functional approach ensures complete situational awareness for accurate target position redetermination.
3Manufacturing precision
If the parking assistance system strictly follows the original target position, then the system maintains precise parking control, but it cannot adapt when the target position becomes unattainable due to obstacles
Solution Approach 1:
The system dynamically adjusts the target position based on real-time conditions. The target position is not fixed but can be redetermined when obstacles are detected or when vehicle state indicates the original target is unattainable. This dynamic adaptation maintains parking precision while providing necessary flexibility to handle unexpected situations.

AI summary
A method to park a vehicle using a parking assistance system, a target position of the vehicle within a parking space is automatically determined. A parking process of the parking assistance system is considered successfully ended when the vehicle reaches the target position. In order to carry out the parking process of the parking assistance system, a steering intervention in a steering system of the vehicle is automatically activated. A state that prevents the target position from being reached is automatically detected during the parking process. Depending on the state, the target position is newly determined and the parking process is continued with the newly determined target position.
