Solution Overview

Problem

Existing remote support systems for mobile vehicles face significant challenges in managing processing loads and data traffic, leading to excessive burdens on business operators, which can result in increased infrastructure costs and traffic costs.

Innovation Solution

A method and system that calculate processing loads and data traffic per unit time, and when these exceed predetermined upper limits, propose an avoidance route to the target mobile vehicle based on positional and map information, thereby reducing the load on the server and data traffic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If remote support is executed intensively for multiple mobile vehicles, then service quality and user support are improved, but processing load on the server and data traffic increase excessively

Engineering Contradiction:
Improveservice qualityVSAvoidprocessing load
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mobile vehicle autonomously determines whether to execute remote support based on received guidance information, rather than requiring continuous server-initiated support. The vehicle's own determination unit assesses whether conditions meet thresholds for remote support, making the system self-regulating and reducing unnecessary server processing load while maintaining service quality when needed

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The server pre-calculates and transmits guidance information to the mobile vehicle before remote support is actually needed. This guidance information contains predetermined conditions and thresholds that the vehicle can use to autonomously decide whether to initiate remote support, allowing the server to prepare in advance without bearing the continuous processing burden of real-time decision-making for multiple vehicles

Inventive Principle:
Principle #10Preliminary action

2Reliability

If remote support is executed intensively for multiple mobile vehicles, then service quality is improved, but infrastructure investment and traffic cost increase

Engineering Contradiction:
Improveservice qualityVSAvoidtraffic cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The mobile vehicle autonomously determines whether to execute remote support based on received guidance information, rather than requiring continuous server-initiated support. The vehicle's own determination unit assesses whether conditions meet thresholds for remote support, making the system self-regulating and reducing unnecessary server processing load while maintaining service quality when needed

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements remote support selectively rather than continuously - only when the mobile vehicle's determination unit finds that current conditions meet the predetermined thresholds in the guidance information. This partial action approach ensures service quality is maintained when necessary while avoiding excessive data traffic and infrastructure costs during periods when remote support is not needed

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A processing load of a server (MS) configured to manage a remote support or data traffic per unit time in sending/receiving between a target mobile vehicle of the remote support and the server is calculated. Positional information of a current location and a destination of the target mobile vehicle and map information containing the current location and the destination are obtained. When the processing load is equal to or greater than an upper limit load or when the data traffic per unit time is equal to or greater than an upper limit amount, a proposal is made to the target mobile vehicle for an avoidance route (ART) for avoiding an occurrence of the remote support based on the positional information and the map information.
