Automatic Drive Vehicle Control Device Power Generator Abnormality Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic drive vehicles face instability in operations due to abnormalities in the power generator, leading to insufficient power supply for auxiliary devices, which can prevent normal starting and continuation of automatic driving.
Innovation Solution
A control device that includes an information acquisition unit to gather power generator information, an operation control unit to switch between unrestricted and restricted automatic driving states, and a determination unit to decide on state changes based on the power generator information, allowing partial or complete restriction of automatic driving when an abnormality is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power generator operates normally to supply sufficient power, then automatic driving can be executed without restriction, but if the power generator becomes abnormal, then power supply becomes insufficient causing operational instability
Solution Approach 1:
The control device dynamically adjusts the automatic driving state based on power generator status. When an abnormality is detected, the system transitions from unrestricted automatic driving to restricted automatic driving, adapting its functionality to match available power supply capabilities while maintaining operational stability
Solution Approach 2:
The system changes operational parameters by switching between different automatic driving states (first state with full functionality, second state with restricted functionality) based on power generator performance. This parameter adjustment allows the vehicle to continue operating safely under reduced power conditions
2Reliability
If the power generator is restricted due to abnormality, then operational stability is maintained, but the automatic driving functionality is partially or entirely lost
Solution Approach 1:
When power generator abnormality is detected, the system implements partial action by maintaining restricted automatic driving functionality rather than completely disabling it. This allows essential automatic driving operations to continue with reduced capabilities, balancing stability maintenance with preserved productivity
Solution Approach 2:
The control device automatically detects power generator abnormalities and self-adjusts the automatic driving state without external intervention. The system monitors its own power supply status and autonomously transitions between operational modes to maintain stability while preserving necessary driving functionality

AI summary
A control device of an automatic drive vehicle includes: an information acquisition unit that acquires power generator information as information on a power generator provided in the automatic drive vehicle; an operation control unit that switches between a first state in which automatic driving of the automatic drive vehicle is executed without restriction and a second state in which the automatic driving is partially or entirely restricted; and a determination unit that determines whether to perform switching to the second state by the operation control unit.
