Parking Support Display Form Adaptation for Driver Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems fail to prevent sudden changes in displayed parking space information as the vehicle moves, leading to confusion for the driver.
Innovation Solution
The system displays a first parking space in a specific form when it satisfies the parking condition and changes the display form when it is estimated or detected that the space will no longer satisfy the condition or when another space will become suitable, allowing the driver to prepare for the change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the parking space display is updated in real-time as the vehicle moves, then the information accuracy is improved, but the display stability deteriorates causing sudden changes that confuse the driver
Solution Approach 1:
The system performs preliminary actions by detecting in advance when a parking space will no longer satisfy parking conditions before the vehicle actually reaches that point. The display form is changed proactively to notify the driver of upcoming changes, preventing sudden unexpected changes and maintaining display stability while keeping information accurate.
2Loss of information
If the display form changes frequently to reflect real-time parking space changes, then the information freshness is improved, but the driver's response time deteriorates
Solution Approach 1:
The system changes the display form in advance before the parking space actually becomes unsuitable, giving the driver sufficient time to respond and select an alternative parking space. This preliminary notification approach maintains information freshness while preventing loss of response time by providing advance warning rather than waiting until the last moment.
3Reliability
If the system continuously monitors and updates parking space suitability, then the reliability is improved, but the system complexity increases
Solution Approach 1:
The system dynamically changes the display form based on the vehicle's proximity to parking spaces and changing conditions, rather than using static display methods. This dynamic approach improves reliability by adapting to real-time conditions while managing complexity through focused, context-dependent updates rather than continuous comprehensive monitoring.

AI summary
A method of displaying parking assist information is used in a parking assist apparatus comprising a display and a control device. The control device displays a first parking space in a first display form on the display. The first parking space satisfies a parking condition that is preliminarily defined. When it is estimated that the first parking space will not satisfy the parking condition or a second parking space other than the first parking space will satisfy the parking condition, the control device displays the first parking space in a second display form different from the first display form on the display.
