Solution Overview

Problem

Conventional vehicle data collection systems fail to effectively manage processing loads when multiple systems access the same vehicle resources, leading to potential resource insufficiencies and competition.

Innovation Solution

A vehicle control device with an equipment management unit, API unit, state prediction unit, and information generation unit to predict resource availability and provide reference information to application software, allowing controlled access to vehicle functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple systems access the same vehicle resources simultaneously, then service coverage and functionality are improved, but resource insufficiency and system competition occur

Engineering Contradiction:

Improveservice coverageVSAvoidresource availability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a reservation mechanism where systems can pre-book vehicle resources for future time periods. The reservation management unit stores reservation information including time periods and required resources, allowing systems to secure resources in advance before actual access occurs, thus preventing resource conflicts while maintaining high service coverage

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The state prediction unit predicts future resource states based on current usage patterns and reservation information. This feedback mechanism allows the system to anticipate resource availability and make informed decisions about granting or denying access requests, ensuring reliable resource allocation even with multiple competing systems

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If vehicle resources are allocated to multiple competing systems, then system functionality is improved, but processing load management becomes difficult

Engineering Contradiction:

Improvesystem functionalityVSAvoidprocessing load management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a reservation management unit as an intermediary between multiple systems and vehicle resources. This intermediary handles all resource allocation decisions, maintaining a centralized registry of reservations and coordinating access requests, thereby simplifying load management despite multiple competing systems

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments resource allocation into discrete time-period based reservations. Each reservation is independently managed with specific start and end times, allowing the system to divide continuous resource usage into manageable segments that can be independently controlled and tracked

Inventive Principle:

Principle #1Segmentation

AI summary

A vehicle control device includes an API unit, which has multiple function APIs. The multiple function APIs are interfaces to respectively implement multiple functions using vehicle equipment. Each function API receives a request from an application and provides corresponding function using the vehicle equipment. The vehicle control device predicts a state of resource of the vehicle for a specified time period, and generates, for each function API, reference information, which includes a time period during which the corresponding function API can be used based on the prediction result. The vehicle control device provides the reference information to the function API specified in the request from the application.
