In-Vehicle Control Device Version Match Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle control systems face excessive processing overhead due to redundant inquiries for equipment information during version match checks, which can lead to delays in service startup and increased complexity in managing service start waiting times.
Innovation Solution
An in-vehicle control device with a processing circuit that collectively acquires equipment information from in-vehicle equipment for version match checks, allowing each application to start services once the check is completed, thereby reducing redundant data acquisition and processing overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each application individually performs version match checks, then version compatibility can be verified for each application, but excessive processing overhead is generated due to redundant equipment information inquiries
Solution Approach 1:
The patent merges multiple individual version match checks into a single collective check. The control device performs one unified equipment information acquisition process that serves all applications, combining what would otherwise be separate redundant inquiries into one efficient operation.
Solution Approach 2:
The control device implements a universal equipment information acquisition mechanism that serves multiple applications simultaneously. This single acquisition process provides equipment information to all applications that need it, making the system multi-functional and eliminating the need for each application to perform separate acquisitions.
2Reliability
If each application individually performs version match checks, then each application can ensure its specific equipment requirements are met, but service startup is delayed due to redundant processing
Solution Approach 1:
The control device performs equipment information acquisition in advance as a preliminary action before any application needs it. This single preliminary acquisition provides all necessary information to multiple applications, eliminating the need for repeated acquisitions and reducing overall service startup time.
Solution Approach 2:
Multiple sequential version match check operations are merged into one simultaneous collective check. The control device acquires equipment information once and makes it available to all applications at the same time, rather than having applications wait in sequence for individual checks to complete.
3Reliability
If multiple applications perform version match checks simultaneously, then comprehensive equipment verification is achieved, but processing complexity increases due to managing multiple inquiries
Solution Approach 1:
The control device acts as an intermediary between the equipment information source and multiple applications. It centrally manages the single equipment information acquisition process and distributes the information to all applications that need it, simplifying what would otherwise be complex multi-to-multi communication and coordination.
Solution Approach 2:
The patent segments the system into two distinct functional parts: a centralized control device that handles equipment information acquisition, and multiple applications that consume this information. This segmentation separates the complex acquisition and management tasks from the applications, reducing overall system complexity.
Data Source
AI summary
An in-vehicle control device is configured to execute a plurality of applications that provides a service. The in-vehicle control device includes a processing circuit configured to collectively acquire, from in-vehicle equipment, equipment information based on which a version match check of each of the applications is performed, the equipment information being information on the in-vehicle equipment. The version match check is a check performed for confirming that in-vehicle equipment necessary for providing the service is installed in a vehicle. Each of the applications is configured to start the service under a condition that the version match check is completed.
