Vehicle Parking-Intent Prediction for Non-Blocking Driving Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving systems cannot effectively prevent the inhibition of parking operations for preceding vehicles before they start, leading to potential delays or failures in responding to sudden parking actions by host vehicles.
Innovation Solution
A moving body control device that includes an external environment recognition unit, an acquisition unit, a determination unit, and a control unit, which acquire and analyze data to determine if another moving body is likely to park in the surrounding area and perform predetermined controls to prevent inhibition of its parking operation, such as deceleration, stopping, or changing lanes, based on stored parking position data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host vehicle maintains normal driving behavior without predictive control, then the device complexity and control algorithms remain simple, but the host vehicle cannot respond in time when the preceding vehicle suddenly starts parking operation
Solution Approach 1:
The determination unit performs preliminary analysis by referring to stored parking position data to predict whether the preceding vehicle is likely to park at a surrounding parking position before the parking operation actually starts. This preliminary action enables the control unit to initiate appropriate control measures in advance, ensuring timely response when the preceding vehicle suddenly begins parking.
2Reliability
If the host vehicle performs predictive control to prevent inhibiting parking of the preceding vehicle, then the response time and reliability improve, but the device complexity and control algorithms increase
Solution Approach 1:
The system performs preliminary determination by comparing the preceding vehicle's current state with stored parking position data to predict future parking intentions. This preliminary action allows the control unit to prepare and execute appropriate control measures before the parking operation begins, improving reliability without requiring complex real-time decision-making systems.
Solution Approach 2:
The determination unit continuously monitors the preceding vehicle's state and compares it with stored parking position data, creating a feedback mechanism that informs the control unit's decisions. This feedback-based approach enables predictive control by using historical parking position information to anticipate future parking operations, improving reliability through data-driven decision-making.
3Productivity
If the host vehicle responds only after the preceding vehicle starts parking operation, then the control algorithms remain simple, but the parking operation may be inhibited causing delays or failures
Solution Approach 1:
The system performs preliminary determination by referring to stored parking position data to predict whether the preceding vehicle is likely to park at a surrounding parking position before the parking operation actually starts. This preliminary action enables the control unit to initiate appropriate control measures in advance, ensuring timely response when the preceding vehicle suddenly begins parking.
Solution Approach 2:
The control unit performs preliminary anti-action by taking control measures before the preceding vehicle's parking operation begins. Based on the determination unit's prediction, the control unit adjusts the host vehicle's behavior in advance to prevent inhibition of the preceding vehicle's parking operation, thereby ensuring smooth and timely parking completion.

AI summary
A moving body control device includes: an external environment recognition unit configured to acquire recognition data of an external environment including a surrounding area of a moving body; an acquisition unit configured to acquire, based on the recognition data, other moving body information indicating a feature of another moving body in the surrounding area; a determination unit configured to refer to a storage unit that stores parking position data in which a parking position and a feature of a moving body parked at the parking position are associated with each other and determine whether there is a possibility that the other moving body is to be parked at a surrounding parking position; and a control unit configured to perform predetermined control to prevent the moving body from inhibiting parking toward the surrounding parking position based on a determination that there is the possibility.
