Parking Collision Avoidance Control by Vehicle-to-Space Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle collision avoidance systems, especially during parking, the processing load is high due to a large number of surrounding vehicles and pedestrians, and the small turning radius leads to decreased accuracy in detecting objects, resulting in inefficiencies and false detections.
Innovation Solution
A control apparatus that includes a parking determination unit and a collision avoidance unit, which activates or deactivates the collision avoidance function based on the angle between the vehicle's direction and the parking space's direction, using a threshold value to optimize the function's execution and reduce processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the collision avoidance function is continuously activated during parking, then collision safety is improved, but the processing load increases due to large number of surrounding vehicles and pedestrians
Solution Approach 1:
The collision avoidance function is dynamically activated or inactivated based on the parking determination result and angle condition, rather than being continuously on. This dynamic control reduces processing load while maintaining safety when needed
Solution Approach 2:
The system changes the operational state parameter of the collision avoidance function (activated/inactivated) based on detected conditions (parking state and angle), optimizing the balance between safety and processing load
2Reliability
If the collision avoidance function is continuously activated during parking, then collision safety is improved, but false detections increase due to small turning radius
Solution Approach 1:
The system changes the operational state parameter of the collision avoidance function based on detected conditions (parking state and angle), optimizing the balance between safety and detection accuracy
Solution Approach 2:
The system preliminarily determines the parking state and angle before activating the collision avoidance function, preventing false detections from occurring in the first place rather than correcting them later
3Reliability
If the collision avoidance function is activated at all parking angles, then safety coverage is improved, but system complexity increases
Solution Approach 1:
The collision avoidance function is applied selectively based on local conditions (angle threshold and parking state) rather than uniformly across all situations, simplifying the control logic while maintaining appropriate safety coverage

AI summary
A control apparatus of a vehicle included a parking determination unit configured to determine whether the vehicle is about to be parked in a parking space, and a collision avoidance unit configured to be able to execute an avoidance function for avoiding collision with an object that is moving in a direction intersecting a longer direction of the vehicle. While the vehicle is about to be parked in the parking space, in a case where an angle between the longer direction of the vehicle and a longer direction of the parking space is larger than a threshold value, the collision avoidance unit inactivates the avoidance function, and in a case where the angle between the longer direction of the vehicle and the longer direction of the parking space is smaller than the threshold value, the collision avoidance unit activates the avoidance function.
