Solution Overview

Problem

Conventional parking assistance systems do not account for business vehicles stopping and lining up in stop areas, leading to insufficient stop intervals for loading/unloading luggage, especially when multiple vehicles are parked side by side.

Innovation Solution

A stop position control system that acquires vehicle and luggage information, sets a necessary stop interval based on this information, and transmits it to adjacent vehicles to ensure a sufficient stop interval for loading/unloading luggage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple vehicles are parked side by side in a stop area, then the stop area utilization is improved, but the stop interval required for loading/unloading luggage cannot be sufficiently ensured

Engineering Contradiction:
Improvestop area utilizationVSAvoidstop interval for loading/unloading luggage
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of luggage in the stop area before vehicles complete parking. The management device identifies luggage positions and predicts potential obstructions in advance, allowing the system to pre-calculate alternative parking positions that ensure adequate stop intervals for luggage loading/unloading operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The management device acts as an intermediary between parked vehicles and approaching vehicles. It detects luggage positions, determines necessary stop intervals, and communicates this information to control devices of approaching vehicles, enabling them to adjust their stop positions to maintain appropriate intervals for luggage operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If the host-vehicle is parked at the parking target position, then the parking precision is improved, but another vehicle may be parked adjacent to the host-vehicle causing insufficient stop interval

Engineering Contradiction:
Improveparking precisionVSAvoidstop interval for loading/unloading luggage
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system implements feedback by continuously monitoring the stop area for approaching vehicles and luggage positions. When a vehicle is parked, the management device detects subsequent approaching vehicles and their associated luggage, then provides feedback to adjust the stop position to ensure adequate intervals are maintained while preserving the original parking precision.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts stop positions based on real-time conditions. While the host-vehicle maintains its precise parking position, approaching vehicles receive dynamic position adjustments based on detected luggage locations and calculated necessary stop intervals, allowing the system to adapt to changing conditions without compromising overall parking precision.

Inventive Principle:
Principle #15Dynamics

AI summary

A stop position control system of the present invention includes a controller configured to control the stop position of a stop vehicle that is to stop in a stop area. In the stop position control system, vehicle information on the stop vehicle and luggage information on luggage possessed by a user who is using the stop vehicle are acquired, a necessary stop interval required for loading/unloading the user's luggage from the stop vehicle in the stop area is set based on the vehicle information and the luggage information, and the necessary stop interval is transmitted to an adjacent vehicle that is to stop adjacent to the stop vehicle.
