Vehicle Theft Prevention Device for Automatic Valet Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle theft prevention technologies do not adequately address security during automatic valet parking and fail to ensure the safety of both the vehicle and its contents, as they do not consider the transition of the vehicle's state from a theft prevention mode to a normal driving mode based on the occupant's presence or absence, particularly in scenarios involving automatic valet parking.
Innovation Solution
A vehicle theft prevention device that includes a device control unit which, upon receiving an exit instruction, performs first change processing to transition the vehicle's cabin facilities from a theft prevention state to a normal state when the vehicle arrives at the user position, ensuring the vehicle can be driven and reducing the risk of theft, and performs second change processing to re-enter theft prevention mode after the user is no longer in proximity, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seat and steering wheel are maintained in a theft prevention position, then vehicle and article security is improved, but user access and smooth entry into the vehicle deteriorates
Solution Approach 1:
The patent applies dynamics by making the seat and steering wheel positions changeable between a theft prevention position and a normal position. The control unit dynamically adjusts these components based on whether the vehicle is in automatic valet parking mode or normal operation, allowing the system to adapt its security level to the current operational context while maintaining ease of access when needed.
Solution Approach 2:
The system implements self-service by automatically transitioning the seat and steering wheel between positions based on the vehicle's operational state. When the vehicle enters or exits automatic valet parking mode, the control unit autonomously adjusts the components without requiring manual intervention from the user, thus maintaining both security and convenience.
2Ease of operation
If the seat and steering wheel are returned to normal position from theft prevention position, then smooth entry into the vehicle is improved, but vehicle and article security deteriorates
Solution Approach 1:
The system dynamically adjusts the seat and steering wheel positions based on the vehicle's operational mode. When automatic valet parking is active, components remain in theft prevention position; when the mode is inactive, they transition to normal position for easy access. This dynamic adaptation resolves the contradiction by contextually determining the appropriate security level.
Solution Approach 2:
The control unit automatically manages the position transitions of the seat and steering wheel based on the vehicle's operational state, eliminating the need for manual user intervention. The system self-regulates security levels according to whether automatic valet parking is enabled, providing both security and convenience as needed.
3Reliability
If existing theft prevention technologies are used without considering automatic valet parking, then general vehicle security is improved, but security during automatic valet parking operations deteriorates
Solution Approach 1:
The patent implements universality by designing a theft prevention system that functions effectively in both traditional parking scenarios and automatic valet parking operations. The control unit monitors the vehicle's operational mode and adjusts component positions accordingly, allowing the same system to provide appropriate security levels for multiple different use cases without requiring separate dedicated systems.

AI summary
A vehicle theft prevention device includes: a device control unit that starts, when performing exit processing for causing a vehicle to move from a parking position to a user position by an autonomous driving control of the vehicle in response to an exit instruction to the vehicle from a terminal of the user outside the vehicle, performing first change processing for changing a state of facilities in a vehicle cabin of the vehicle from a theft prevention state in which theft of the vehicle and articles in the vehicle cabin is prevented to a normal state in which the vehicle is able to be driven by the user such that the first change processing ends when the vehicle arrives at the user position.
