Automatic Parking Restart After Door-Open Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems require users to restart the automatic parking process and input the target position again if the vehicle door is opened before reaching the parking position, which impairs user convenience and increases the time required to complete the parking operation.
Innovation Solution
A parking assist apparatus that includes a holding device to maintain the target parking position, an automatic parking device for controlling the vehicle's parking, and a transition device to change the automatic parking control into a standby state when the door is opened before arrival, allowing for seamless restart of the parking process without resetting the target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automatic parking control is ended when the door is opened before arrival at target position, then the safety is improved, but the user convenience deteriorates
Solution Approach 1:
The system dynamically transitions between different operational states (automatic parking control state, standby state, and initial state) based on door opening detection and vehicle position. This allows the system to maintain safety by pausing operations while preserving user intent, enabling convenient restart without full re-initialization.
Solution Approach 2:
The system performs preliminary actions by holding the target parking position information in memory before the door is opened. This preliminary preservation of data allows the system to resume operations quickly after door closure without requiring users to re-input destination information, thus maintaining both safety and convenience.
2Reliability
If the automatic parking control is ended when the door is opened, then the system reliability is improved, but the time required to restart parking control increases
Solution Approach 1:
The system performs preliminary preservation of target position information in the holding device before interruption occurs. This allows rapid resumption of automatic parking control after door closure without requiring time-consuming re-input of destination data, thereby reducing restart time while maintaining system reliability.
Solution Approach 2:
The system maintains continuity of useful action by preserving the target parking position information and transitioning to a standby state rather than fully terminating the operation. This enables quick resumption of the parking control process, minimizing time loss while ensuring system reliability through proper state management.
3Device complexity
If the target parking position is not held after door opening, then the system complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The system performs preliminary preservation of target position information in the holding device before interruption. This simple memory function maintains low system complexity while significantly improving ease of operation by enabling convenient restart without re-inputting destination information.
Solution Approach 2:
The system provides self-service by automatically retaining the target parking position information and managing the transition between states. This eliminates the need for users to manually re-input destination data, improving ease of operation while requiring only minimal additional system components for information preservation.

AI summary
A parking assist apparatus is provided with: a holding device configured to hold the target parking position associated with the parking process operation; an automatic parking device configured to perform an automatic parking control of automatically controlling the vehicle such that the vehicle is parked in the target parking position, as a part of the parking process operation; and a transition device configured to change the automatic parking control into a standby state while allowing the holding device to hold the target parking position, on condition that a door of the vehicle is opened before the vehicle arrives at the target parking position. The transition device is configured to allow the automatic parking device to restart the automatic parking control, on condition that there is an execution request for the automatic parking control, when the automatic parking control is in the standby state.
