Parking Assistance Range Selection for Fast Parking Space Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In parking lots, it is challenging to specify a suitable parking spot for a vehicle while traveling, due to the need for higher speeds and obstacles like other vehicles, making it difficult to set a target parking position.
Innovation Solution
A parking assistance device that uses surrounding monitoring sensors to search for parking spaces, provides users with area information including multiple parking spots as a designated range, and allows users to select a target parking position, utilizing recognition capabilities to effectively set the target parking position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle travels at higher speeds to improve search efficiency, then productivity is improved, but measurement precision of parking spot specification deteriorates
Solution Approach 1:
The parking space search process is segmented into two distinct phases: search traveling phase and parking assistance phase. During search traveling, the system provides area information covering multiple parking spots to maintain high speed efficiency. When parking assistance is activated, the system transitions to precise spot specification mode, allowing the user to select from displayed parking spot information. This segmentation allows the system to optimize for speed during search and for precision during final selection.
Solution Approach 2:
The system dynamically adjusts the level of information detail provided to the user based on the current phase. During search traveling, area information showing multiple parking spots is displayed to enable quick assessment. When the user activates parking assistance, the system dynamically transitions to displaying detailed parking spot information for precise selection. This dynamic adaptation allows the system to balance search efficiency with specification accuracy based on real-time user needs.
2Measurement precision
If the system specifies a single parking spot to improve precision, then measurement precision is improved, but ease of operation deteriorates due to increased user burden
Solution Approach 1:
The system performs preliminary action by automatically searching for and identifying suitable parking spaces before the user needs to make a selection. The area information is pre-calculated and displayed, showing multiple viable parking spots with their locations and characteristics. This preliminary preparation reduces the user burden by eliminating the need for manual searching and assessment, while still providing precise spot specification when the user activates parking assistance.
Solution Approach 2:
The system acts as an intermediary between the user's high-level intent (find a parking spot) and the low-level execution (navigate to specific coordinates). By providing area information that includes multiple parking spots with detailed characteristics, the system mediates the complexity of parking lot navigation, allowing the user to make informed selections without bearing the full operational burden of manual spot identification and navigation.
3Ease of operation
If area information including multiple parking spots is provided to improve ease of operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system extracts and displays only the essential information needed for user decision-making during search traveling. Area information is presented with key characteristics such as location, size, and availability status, while more detailed spot-specific data is extracted and displayed only when parking assistance is activated. This selective extraction reduces device complexity by avoiding the need to process and display all possible information simultaneously, while still providing adequate user convenience.
Solution Approach 2:
The system dynamically adjusts the level of information detail and processing based on the operational phase. During search traveling, simplified area information is provided with lower processing requirements. When parking assistance is activated, the system dynamically increases information detail and processing capacity to provide precise parking spot specifications. This dynamic adaptation allows the system to maintain ease of operation while managing device complexity according to real-time needs.

AI summary
A parking assistance device is configured to search for a parking space for parking a vehicle in a parking lot based on surrounding information of the vehicle, provide a user with information for prompting a selection of a target parking space for parking the vehicle from the parking space, and set a target parking position of the vehicle based on the target parking space. The parking assistance device provides the user with area information having a range including a plurality of parking spots in the parking space as a designated range.
