Parking Steering Assist for Stationary and Moving Obstacle Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering assist systems for vehicles fail to efficiently handle stationary obstacles during parking, leading to prolonged parking times as they do not promptly recognize or adapt to stationary objects in the vehicle's path, causing unnecessary delays and potential collisions with moving objects.
Innovation Solution
A steering assist apparatus that determines whether newly detected objects are stationary or moving, immediately canceling or pausing the steering assist control based on the object's type and positional relationship with the vehicle's path, informing the driver to facilitate quicker parking decisions.

Engineering Contradiction Analysis
1Productivity
If the steering assist control continues without interruption when a new obstacle is detected, then the parking process may be completed faster, but the vehicle may collide with stationary objects that were not detected initially
Solution Approach 1:
The system dynamically adjusts the parking assist control based on real-time obstacle detection. When a stationary obstacle is detected during parking, the control is immediately canceled, whereas for moving objects, the control is temporarily paused with a warning to the driver. This dynamic response strategy optimizes both parking efficiency and safety by adapting to different obstacle types.
Solution Approach 2:
The system continuously monitors the parking environment using sensors and provides feedback about detected obstacles. When obstacles are detected, the system feedbacks this information to the control unit, which then adjusts the parking assist control accordingly - canceling for stationary objects or pausing with warnings for moving objects, ensuring safe parking operation.
2Reliability
If the steering assist control is immediately canceled when any new obstacle is detected, then collision avoidance is improved, but parking time increases due to unnecessary cancellations for moving objects
Solution Approach 1:
The system applies different quality treatments to different types of obstacles. Stationary obstacles trigger immediate control cancellation, while moving objects trigger a temporary pause with driver warning. This localized differentiation in response strategy optimizes the balance between safety and parking efficiency based on the specific obstacle characteristics.
Solution Approach 2:
The system changes the control parameter (cancellation vs. pause) based on the detected obstacle type. For stationary obstacles, the control parameter is set to immediate cancellation, while for moving objects, it is set to temporary pause with warning, allowing the system to adapt its behavior to different environmental conditions and optimize both safety and time efficiency.
3Reliability
If the system waits for a certain time period before canceling control when a new obstacle is detected, then false alarms are reduced, but the response time to actual obstacles is delayed
Solution Approach 1:
The system performs preliminary classification of the detected obstacle as either stationary or moving before determining the control response. This preliminary action allows the system to immediately determine the appropriate response (cancellation or pause) without waiting for a time period, thus maintaining fast response speed while avoiding false alarms through proper obstacle type identification.
