Solution Overview

Problem

Existing vehicle control systems face challenges in standardizing the identification and control of vehicle equipment due to variations in equipment number and arrangement across different vehicle types, leading to complex management of application software.

Innovation Solution

A vehicle control device that uses location information records, including row and lateral coordinates, to identify and control vehicle-mounted components, allowing for standardization across vehicles with different equipment configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If equipment identification is based on vehicle-specific codes, then equipment can be accurately identified, but program management becomes complex across different vehicle types

Engineering Contradiction:
Improveequipment identification accuracyVSAvoidprogram management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by using a standardized coordinate system that can identify equipment across different vehicle types. Instead of creating vehicle-specific identification codes, the system uses a universal coordinate framework (longitudinal, lateral, vertical coordinates) that works for all vehicles, allowing one program to manage equipment identification across multiple vehicle configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses copying by creating a virtual three-dimensional coordinate model that replicates the physical equipment layout. This virtual model serves as a standardized copy that can be applied across different vehicle types, eliminating the need for custom identification programs for each vehicle configuration.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If equipment arrangement varies across vehicle types, then vehicle customization is flexible, but standardized control becomes difficult

Engineering Contradiction:
Improvevehicle configuration flexibilityVSAvoidcontrol standardization
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent resolves this contradiction by adding dimensional abstraction. Instead of dealing with varying equipment arrangements directly, the system maps all equipment positions into a standardized three-dimensional coordinate space. This dimensional transformation allows flexible physical arrangements to be represented uniformly, enabling standardized control programs to operate across different vehicle configurations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent applies parameter changes by transforming equipment identification from vehicle-specific parameters to standardized spatial parameters. By changing the identification parameters from custom codes to universal coordinates (longitudinal position, lateral position, vertical position), the system maintains adaptability to different configurations while achieving control standardization.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If separate programs are created for each vehicle type, then equipment control is accurate, but software management complexity increases

Engineering Contradiction:
Improveequipment control accuracyVSAvoidsoftware management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal equipment identification program that can accurately control equipment across all vehicle types. By using the standardized three-dimensional coordinate system, a single program can handle equipment identification and control for multiple vehicle configurations, maintaining reliability while eliminating the need for multiple vehicle-specific programs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The control device includes a storage unit, an input unit, and a control unit. The storage unit stores location information record indicating mounting location of each equipment, which includes row location information indicating a mounting location in front-rear direction of vehicle and lateral location information indicating the mounting location in left-right direction of vehicle. The input unit receives a control request to control equipment or vehicle-mounted component correlated to the equipment. The equipment is identified by identification information that defines a front-rear order in front-rear direction of the vehicle and a left-right order in left-right direction of the vehicle. The control unit determines and controls a control target, which is determined as the equipment or vehicle-mounted component correlated to the equipment according the control request based on the identification information included in the control request and the location information stored in the storage unit.
