Vehicle Control Device Distinguishing Lock from Parking Intent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems face challenges in determining whether a remote lock operation is intended for door locking or parking instruction, leading to inappropriate driving control.
Innovation Solution
A vehicle control device and method that includes a recognizer to identify the vehicle's surroundings and locking state, and a driving controller to perform speed and steering control based on recognition results, causing the vehicle to depart when the door is locked after an occupant exits in a predetermined area with specific conditions met, including communication with a terminal device to differentiate between areas and provide notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle executes automated parking when a remote lock operation is received after an occupant exits, then the parking function is automated, but it cannot distinguish between door lock operations and parking instructions leading to inappropriate driving control
Solution Approach 1:
The system uses feedback from multiple sensors (door lock state, occupant detection, location information) to determine whether to execute automated parking. The driving control unit receives feedback about the vehicle's location relative to the parking area and the door lock state, and only executes parking when both conditions indicate a parking intention, thereby resolving the ambiguity between door lock and parking operations
Solution Approach 2:
The patent introduces an intermediary decision-making process that mediates between the remote lock operation and the automated parking execution. This intermediary layer analyzes additional conditions (occupant exit detection, location in parking area, door lock state) before triggering parking, acting as a mediator to distinguish true parking intentions from simple door locking
2Reliability
If the vehicle requires multiple conditions to be met before departing (enhancing safety), then safety is improved, but the control logic becomes more complex
Solution Approach 1:
The patent segments the departure control into distinct functional modules: occupant exit detection, location verification, door lock state monitoring, and departure execution. Each module independently checks one condition, and the overall system integrates these segmented checks through logical operations, making the complex multi-condition control more manageable and reliable

AI summary
According to an embodiment, a vehicle control device includes a recognizer configured to recognize a surrounding environment of a vehicle and recognize a locking state of the vehicle and a driving controller configured to perform driving control of one or both of a speed and steering of the vehicle on the basis of a recognition result of the recognizer. The driving controller causes the vehicle to depart when a door of the vehicle is locked after an occupant of the vehicle gets out of the vehicle in a predetermined area in a state in which predetermined conditions are satisfied.
