Vehicle Operation Management Controller for Safety Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack the ability to intelligently regulate operator commands based on real-time operating conditions, leading to potential unsafe operations and mechanical wear, especially in complex scenarios involving multiple vehicles or varying environmental factors.
Innovation Solution
The Operation Management (OM) system, which electronically interposes between the operator controller and the local vehicle control system, receives operator commands and modifies them based on trigger conditions and sensed external conditions, such as weather, mechanical faults, and load, to ensure safe and efficient operation, minimizing wear on mechanical subsystems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator controller directly controls the vehicle without intermediate regulation, then the operation response is fast and simple, but unsafe operations and mechanical wear may occur
Solution Approach 1:
The patent introduces an operation management controller as an intermediary component between the operator controller and the vehicle's control systems. This mediator receives operator commands, evaluates them against stored operating requirements (speed limits, route selections, time constraints), and generates modified commands that comply with these requirements. This resolves the contradiction by adding safety regulation without requiring fundamental redesign of the control architecture.
Solution Approach 2:
The control system is segmented into distinct functional modules: the operator controller for receiving commands, the operation management controller for evaluating and modifying commands, and the vehicle control systems for execution. This segmentation allows each component to specialize in specific tasks, improving overall reliability while maintaining manageable system complexity through modular design.
2Reliability
If the operator commands are directly executed without modification, then the operational efficiency is high, but mechanical wear and unsafe operations increase
Solution Approach 1:
The operation management controller implements a feedback mechanism by continuously monitoring operator commands and comparing them against stored operating requirements. When commands violate these requirements (such as exceeding speed limits or making unsafe maneuvers), the system generates modified commands that correct the violations while maintaining the operator's intent. This feedback loop protects mechanical subsystems from excessive wear caused by unsafe operations while minimizing disruptions to operational efficiency.
3Reliability
If multiple operating requirements are monitored and enforced, then the vehicle operation safety is improved, but the control system complexity increases
Solution Approach 1:
The operation management controller is designed as a universal evaluation system that can monitor and enforce multiple types of operating requirements simultaneously (speed limits, route selections, time constraints, weather conditions, traffic conditions). By consolidating these diverse monitoring functions into a single multi-functional controller, the system achieves comprehensive safety compliance without proportionally increasing overall system complexity.

AI summary
A vehicle control system includes an operation manager controller electrically coupled to an operator controller of a vehicle and to a local vehicle control system of the vehicle. The operation manager controller receives an operator command from the operator controller and can regulate the operator command to control operation of the vehicle.
