Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic parking systems can shift the direction change stop point during parking, causing driver anxiety and potentially leading to unnecessary braking operations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the direction change stop point is updated based on sensor recognition results during automatic parking, then the parking route accuracy is improved, but driver anxiety increases and unnecessary braking operations occur
Solution Approach 1:
The system dynamically adjusts the direction change stop point based on real-time sensor recognition results during automatic parking. The parking controller continuously updates the stop point position according to detected obstacles and environmental changes, allowing the route to adapt dynamically while maintaining accuracy without causing driver anxiety through excessive updates.
Solution Approach 2:
The system uses feedback from obstacle detection devices and image pickup devices to monitor the parking environment continuously. Based on this feedback, the parking controller adjusts the direction change stop point only when necessary, providing optimal balance between route accuracy and driver comfort by filtering out minor fluctuations that would cause unnecessary updates.
2Adaptability or versatility
If the direction change stop point is updated frequently during automatic parking, then the parking route adapts to obstacles, but driver comfort deteriorates
Solution Approach 1:
The system implements dynamic adaptability by updating the direction change stop point in response to significant obstacle detections while filtering out minor variations. This dynamic approach allows the route to adapt to real environmental changes without excessive updates that would compromise driver comfort and perceived system stability.
3Object-affected harmful factors
If the direction change stop point is kept fixed before parking start, then driver anxiety is reduced, but parking route precision decreases when obstacles are detected
Solution Approach 1:
The system performs preliminary setting of the direction change stop point before automatic parking begins, providing a stable reference that reduces driver anxiety. During parking execution, the system then allows controlled updates when obstacles are detected, balancing the preliminary stability with necessary adaptive precision through conditional update mechanisms.
