Vehicle Remote Parking Availability Control Under Link Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems lack convenience for users in determining the availability of remote parking functions, as they rely solely on communication with a server or terminal device, leading to potential unavailability of the function due to connectivity issues.
Innovation Solution
A control device and method that obtain data on remote parking function availability from both a server and a terminal device, enabling the function when determined available, even if one source fails, by using a control unit to assess availability based on data from the other source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system obtains function availability data solely from a server or terminal device, then the system structure remains simple, but the function availability is reduced due to potential communication failures
Solution Approach 1:
The patent combines multiple data acquisition paths (server and terminal device) into a unified availability determination system. The control device acquires function availability data from both the server and terminal device, merges these data sources, and uses them together to determine whether to provide the function, thereby improving reliability through redundancy
Solution Approach 2:
The patent prepares for potential communication failures by establishing multiple data acquisition channels in advance. By acquiring availability data from both server and terminal device before function execution, the system cushions against the risk of single-point communication failures, ensuring continuous function availability
2Measurement precision
If the system requires successful data acquisition from both server and terminal device, then data accuracy is improved, but the ease of operation is reduced due to stricter access conditions
Solution Approach 1:
The patent applies partial action by requiring availability data from at least one of the server or terminal device rather than mandating both. This allows the system to determine function availability with sufficient accuracy while maintaining operational convenience, as acquiring data from one source is less restrictive than requiring both
3Reliability
If the system implements dual data acquisition from server and terminal device, then communication failure risk is reduced, but the loss of time increases due to additional data acquisition steps
Solution Approach 1:
The patent performs data acquisition from server and terminal device in advance before the function is actually executed. By acquiring availability data beforehand and storing it, the system reduces communication failure risk while minimizing time loss during actual function execution, as the availability determination is already completed
Data Source
AI summary
A control device controls a vehicle having a predetermined function. The control device is configured to obtain, via a network, data on availability of the predetermined function of the vehicle from a server that stores the data, and obtain the data, which is obtained from the server by a terminal device of a user of the vehicle, from the terminal device, and the control device comprises a control unit configured to: determine, when obtaining the data from one of the server and the terminal device fails, whether the predetermined function is available based on the data obtained from the other one of the server and the terminal device; and enable the predetermined function when it is determined that the predetermined function is available.
