Parking Assistance Mode Switching After Manual Parking Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems fail to reliably switch from manual to automated mode when a vehicle has not successfully parked in a target parking space, leading to potential re-parking outside the space due to user error or skill limitations.
Innovation Solution
A parking assistance device with a controller and sensors that determines if parking has failed in manual mode by comparing the target parking state with the actual execution state, and outputs guidance to switch to automated mode, using a user interface to confirm the mode change, enabling autonomous parking into the target space.

Engineering Contradiction Analysis
1Ease of operation
If the user manually retries parking upon receiving a warning, then the user can attempt to correct the parking position, but the vehicle may be parked outside the parking space again depending on the surrounding situation and the driving skill of the user
Solution Approach 1:
The system automatically detects parking failure conditions and switches from manual to automated parking mode without requiring continuous user intervention. The vehicle performs self-correction by automatically executing the automated parking routine when failure is detected, eliminating reliance on user skill for correction.
Solution Approach 2:
The system continuously monitors parking execution state and compares it against the target parking state. When deviation exceeds a threshold indicating failure, the system provides feedback by switching to automated mode, using real-time state information to trigger corrective action.
2Reliability
If the parking mode is switched to automated mode automatically when manual parking fails, then parking accuracy is improved, but the user may not be aware of the mode switch
Solution Approach 1:
The system prepares for the mode transition by detecting failure conditions in advance and switching to automated mode proactively. The automated parking routine is pre-programmed and automatically executed when failure is detected, ensuring seamless transition without delaying the corrective action.
3Reliability
If the system continuously monitors parking execution state to detect failure, then parking accuracy is improved, but the device complexity increases
Solution Approach 1:
The system monitors key parameters of parking execution state (position, orientation, speed) and compares them against threshold values. When parameters deviate beyond acceptable ranges indicating failure, the system triggers automated mode. This parameter-based monitoring provides reliable failure detection using straightforward computational logic.

AI summary
The parking assistance method using a parking assistance device includes: when parking of a subject vehicle is performed in a manual mode, detecting a parking execution state of the subject vehicle and determining, based on the parking execution state, whether or not the parking toward a target parking space is necessary again; and when a determination is made that the parking toward the target parking space is necessary again, outputting, to a user interface, guidance information for switching a parking mode of the subject vehicle from the manual mode to an automated mode.
