Parking Assist Apparatus Adjusts Target Position for Occupant Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist apparatuses do not account for differences in occupant positions during the learning and operating modes, leading to potentially suboptimal parking positions that may hinder easy exit from the vehicle.
Innovation Solution
A parking assist apparatus that includes a learning device to determine the target parking position based on occupant positions during the learning mode and an assisting device to adjust this position if there is a predetermined difference between learning and operating modes, ensuring easier vehicle exit by shifting the parking position accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the parking assist apparatus uses a fixed learning-based target parking position, then the automation and consistency of parking are improved, but the adaptability to different occupant positions and ease of vehicle exit deteriorates
Solution Approach 1:
The parking assist apparatus dynamically adjusts the target parking position based on detected occupant positions. The system transitions from a static, fixed parking position determined solely by learning to a dynamic position that adapts to different occupant configurations. The adjusting device modifies the target parking position in real-time according to the detected difference between learning-period and assist-period occupant positions, enabling the system to adapt to varying conditions while maintaining automation.
Solution Approach 2:
The system changes the parameters of the target parking position based on detected occupant position differences. When the detection device identifies that occupant positions differ between learning and assist periods, the adjusting device modifies parking position parameters (such as lateral position or longitudinal position) to optimize exit conditions. This parameter adjustment resolves the contradiction by allowing the automated system to adapt its output parameters to different operational contexts.
2Productivity
If the parking assist apparatus automatically parks based on learning results without adjustment, then the productivity and efficiency of parking are improved, but the ease of operation for occupant exit deteriorates
Solution Approach 1:
The detection device provides feedback about occupant positions during the assist period, comparing them against the learning period positions. This feedback loop enables the system to detect when adjustment is needed and triggers the adjusting device to modify the target parking position accordingly. The feedback mechanism maintains productivity by keeping the system automated while improving ease of operation by ensuring the parking position is optimized for the current occupant configuration.
Solution Approach 2:
The system performs preliminary detection of occupant positions during the assist period before finalizing the parking maneuver. By detecting occupant positions in advance and adjusting the target parking position beforehand, the system ensures that the vehicle will be parked in an optimal position for exit without compromising the efficiency of the overall parking process. This preliminary action allows the system to prepare the optimal parking position before execution.

AI summary
A parking assist apparatus (13) has: a learning device (131) configured to perform a learning operation for learning, as a target parking position, a position in which a vehicle is parked when the vehicle is parked by a driver's operation; and an assisting device (132) configured to perform a parking assist operation for automatically parking the vehicle in the target parking position on the basis of a learning result of the learning device, if a predetermined condition that there is a predetermined difference between a position of an occupant during an assist period and a position of an occupant during a learning period is satisfied, the assisting device adjusts the target parking position on the basis of the difference so that it is easier to get out of the vehicle after the parking assist operation is finished, compared to a case where the predetermined condition is not satisfied.
