Vehicle Control Apparatus Parking Reliability Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to accurately determine whether a vehicle is in a parking space, leading to dangerous situations when a driver mistakenly presses the accelerator instead of the brake, resulting in unintended acceleration.
Innovation Solution
A vehicle control apparatus that uses image data from a camera to determine the reliability of the vehicle's location within a parking space by assessing the continuity and detection state of parking areas and parked vehicles, employing a multi-stage reliability determination system to prevent erroneous determinations and maintain accurate positioning during travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple binary determination system is used to determine whether the vehicle is in a parking space, then the device complexity is reduced, but the measurement precision and reliability of location determination deteriorate
Solution Approach 1:
The determination system is segmented into multiple reliability levels (first reliability level and second reliability level) based on detection results from different numbers of parking spaces. This segmentation allows the system to maintain high measurement precision by selecting appropriate reliability levels while avoiding excessive complexity through a structured, hierarchical approach rather than a fully complex continuous system.
Solution Approach 2:
The system changes the reliability parameter based on the number of detected parking spaces. When two or more parking spaces are detected, the system transitions to a first reliability level with higher determination accuracy. When only one parking space is detected, it uses a second reliability level. This parameter change approach improves measurement precision adaptively while maintaining manageable system complexity.
2Stability of the object's composition
If the system maintains determination results even when reliability changes during travel, then the stability of location determination is improved, but the responsiveness to actual location changes deteriorates
Solution Approach 1:
The system dynamically adjusts its determination maintenance behavior based on the vehicle's travel state. When the vehicle is detected to be traveling, the system stops maintaining the determination result and allows it to be updated. When the vehicle is stationary or parking, the system maintains the determination result even if reliability changes. This dynamic adjustment resolves the contradiction by making the system responsive during travel while maintaining stability during stationary periods.
Solution Approach 2:
The system uses feedback from the vehicle's travel state detection to control whether determination results are maintained or updated. The travel state information serves as feedback that triggers different behaviors: maintaining determinations during stationary phases and allowing updates during travel phases. This feedback mechanism balances stability and responsiveness based on actual operational conditions.

AI summary
A vehicle control apparatus is provided with a reliability determination unit that determines a reliability related to an own vehicle location as a current location of the own vehicle being in a parking place, using a detection result of a parking space or a parked vehicle around an own vehicle based on image data around the own vehicle captured by a camera; and an own vehicle location determination unit that determines whether the own vehicle location is in the parking place, using a determination result of the reliability determined by the reliability determination unit.
