Vehicle Transport Control for Consistent Fuel and Battery State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Variations in vehicle state, such as fuel and battery levels, due to differences in transport routes and inspection times, lead to inconsistencies in vehicle quality during the manufacturing process, affecting the reliability and efficiency of vehicle production.
Innovation Solution
A control system that identifies vehicle states and determines control content, including transport routes and timing, to minimize differences between actual and target states, ensuring consistent vehicle quality through remote control and autonomous driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different transport routes are used for vehicle transport, then transport flexibility is improved, but vehicle state variations (fuel and battery levels) increase
Solution Approach 1:
The control notification unit receives vehicle state information from the state identification unit and uses this feedback to dynamically adjust transport route assignments. By continuously monitoring actual vehicle states (fuel level, battery level, operation counts) and comparing them with target states, the system optimizes route allocation to minimize state variations across vehicles.
Solution Approach 2:
The system changes the parameters of transport routes (selecting different routes with varying distances and characteristics) based on real-time vehicle state parameters. By adjusting which vehicle takes which route according to their current state, the system maintains transport flexibility while controlling state variations.
2Measurement precision
If inspection time and number of inspections are varied, then inspection thoroughness is improved, but vehicle state consistency deteriorates
Solution Approach 1:
The state identification unit continuously provides feedback on vehicle states including operation counts from driving devices. The control notification unit uses this feedback to adjust inspection schedules and transport routes, ensuring that vehicles undergo appropriate inspection intensity based on their actual usage, thereby maintaining both inspection quality and state consistency.
Solution Approach 2:
The system dynamically adjusts the number and timing of inspections based on real-time vehicle state data. Rather than applying a fixed inspection schedule to all vehicles, the system adapts inspection intensity to each vehicle's actual operation count and state, allowing thorough inspection where needed while maintaining consistency across the fleet.
3Productivity
If remote control is used to manage vehicle transport, then operational efficiency is improved, but control complexity increases
Solution Approach 1:
The control notification unit serves multiple functions: it assigns transport routes, schedules inspections, monitors vehicle states, and adjusts operations dynamically. By consolidating these diverse control functions into a single universal system, the patent achieves high operational efficiency without proportionally increasing control complexity.
Solution Approach 2:
The state identification unit automatically detects and reports vehicle states without manual intervention. The control notification unit autonomously processes this information and makes control decisions, reducing the need for complex manual control mechanisms while maintaining high operational efficiency.

AI summary
A control system for controlling transport of a vehicle in any of steps from production to shipment of the vehicle includes a state identification unit that identifies a vehicle state that is a state of the vehicle, and a control notification unit that determines a control content of the vehicle by using the identified vehicle state and notifies the vehicle of the control content. The control notification unit determines to control at least either one of a transport route of the vehicle and a timing of starting the transport as the control content such that a magnitude of a difference between the vehicle state and a preset target state is suppressed.
