Automatic Parking Control System with Mobile Object Crossing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic parking control systems struggle to perform convenient parking when a mobile object, such as another vehicle, is present around the vehicle, as they do not adequately examine the circumstances of mobile objects passing around the vehicle.
Innovation Solution
An automatic parking control system that includes a path calculation unit, a parking control unit, a mobile object detection unit, a crossing determination unit, and a parking control adjustment unit, which adjusts the parking path or temporarily stops the vehicle to minimize interference with mobile objects detected on the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional automatic parking control stops or suspends when any obstacle is detected in stop range or suspension range, then collision avoidance is improved, but movement of mobile objects is interrupted and parking convenience deteriorates
Solution Approach 1:
The system applies different quality levels of obstacle response based on object characteristics. For mobile objects, the system determines whether to stop or allow passage based on specific conditions (crossing determination), rather than applying a uniform stop command to all obstacles. This localized differentiation resolves the contradiction by making the response appropriate to each situation.
Solution Approach 2:
The system dynamically adjusts the parking control behavior based on real-time detection of mobile objects and their trajectories. Rather than using fixed stop/suspend ranges for all obstacles, the system continuously evaluates whether mobile objects will cross the parking path and adjusts control accordingly, enabling convenient parking when safe while maintaining collision avoidance.
2Reliability
If automatic parking control is restricted to parking lots only, then safety is improved by avoiding mobile objects on roads, but versatility deteriorates
Solution Approach 1:
The system performs preliminary detection and determination of mobile object trajectories before executing parking maneuvers on roads. By advance identifying whether mobile objects will cross the planned parking path, the system can safely enable road parking when conditions permit, thus improving versatility without compromising safety.
Solution Approach 2:
The system continuously monitors the environment during automatic parking control, detecting mobile objects and their movement patterns. This feedback mechanism allows the system to adapt to road environments dynamically, adjusting control based on real-time conditions rather than simply restricting operation to parking lots, thereby enhancing versatility while maintaining safety.

AI summary
[Problem to be Solved] To provide an automatic parking control system that can perform convenient automatic parking control even in a state in which a mobile object is present around a vehicle. [Solution] An automatic parking control system 1 includes: a path calculation unit 21 that sets, as a target parking position, a parking zone P facing a road B and calculates a parking path R for moving a vehicle 100 on the road B to the target parking position; a parking control unit 22 that is configured to perform automatic parking control for parking the vehicle 100 at the target parking position according to the parking path R; a mobile object detection unit 23 that detects a mobile object A present on the road B; a crossing determination unit 24 that determines whether the route of the mobile object A and the parking path R cross each other; and a parking control adjustment unit 27 that adjusts the automatic parking control performed by the parking control unit 22, when the crossing determination unit 24 determines that the route of the mobile object A and the parking path R cross each other.
