Solution Overview

Problem

Existing vehicle simulation technologies do not account for the changes in driving environment due to maintenance and consumable deterioration, leading to a less realistic simulation experience.

Innovation Solution

A vehicle management system that simulates a driving environment by incorporating maintenance indicators to virtually perform maintenance, changing the simulated environment based on these indicators, and further adjusting the environment in response to maintenance actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a simulation of driving environment is performed without factoring in maintenance, then the simulation can be kept simple and computationally efficient, but the realism and accuracy of the driving environment simulation deteriorates

Engineering Contradiction:
Improvesimulation accuracyVSAvoidsimulation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system pre-calculates and stores maintenance indicators and their effects on driving environment parameters before actual simulation runs. This allows the simulation to quickly reference pre-computed maintenance data without performing complex real-time calculations, thereby improving accuracy while maintaining computational efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces maintenance indicators as intermediary parameters that mediate between vehicle maintenance status and driving environment simulation. These indicators serve as simplified representations of complex maintenance states, allowing the simulation to account for maintenance effects without directly modeling all underlying mechanical processes

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If maintenance is virtually performed on the virtual mobility, then the driving environment can be restored to original state, but additional processing steps and complexity are introduced

Engineering Contradiction:
Improvedriving environment restorationVSAvoidcontrol processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms where maintenance indicators are continuously monitored and compared against threshold values. When maintenance is virtually performed, the system uses feedback loops to adjust driving environment parameters back to their original states, ensuring reliable restoration while automating the control process to minimize complexity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent creates virtual copies of maintenance processes and their effects on the driving environment. By simulating maintenance actions in the virtual model rather than physically performing them, the system can restore driving environment parameters to original states without the complexity of managing physical maintenance operations in the simulation

Inventive Principle:
Principle #26Copying

AI summary

A vehicle management system that is applied to a vehicle includes one or more processors and virtual maintenance. The one or more processors generate a simulated driving environment that simulates a driving environment of virtual mobility. The virtual maintenance is maintenance to be virtually performed on the virtual mobility. The one or more processors execute first environment change processing of changing the simulated driving environment, based on a maintenance indicator indicating a degree of need for the virtual maintenance, and execute second environment change processing of changing the simulated driving environment, according to at least the virtual maintenance.
