Vehicle Controller Biometric State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to effectively secure a remote driving operator before or when an abnormal state compromises manual driving by the occupant, potentially leading to safety risks during vehicle operation.
Innovation Solution
A vehicle controller device equipped with a communication section, biometric information acquisition, travel plan generation, and state determination capabilities, which notifies an external operation device of abnormal states and enables switching to remote or autonomous driving to ensure safe operation by securing a remote operator or switching to autonomous driving if immediate remote operation is not possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the system waits to secure a remote operator after an abnormal state is detected, then the response time is reduced, but the safety risk increases because manual driving may already be compromised
Solution Approach 1:
The notification section notifies the operation device of the determined state in cases where either the abnormality predicted state or the abnormal state is determined to have arisen, enabling the remote operator to prepare in advance before the abnormal state fully develops or takes effect
2Reliability
If the system switches to remote driving immediately when an abnormal state is detected, then safety is improved, but the complexity of the switching mechanism increases
Solution Approach 1:
The travel control section dynamically switches between manual driving, autonomous driving, and remote driving modes based on the occupant's state and the availability of a remote operator, allowing the system to adapt its control strategy in real-time
Solution Approach 2:
The autonomous driving mode serves as an intermediary state between manual and remote driving, providing a safe transition mechanism when a remote operator is not immediately available
3Measurement precision
If the system uses biometric information to detect abnormal states, then the detection accuracy is improved, but the device complexity increases due to additional sensors
Solution Approach 1:
The biometric information acquisition section uses sensors that can detect multiple types of biometric data (facial expressions, voice characteristics, heartbeat, sweating) to comprehensively assess the occupant's state, making the detection system versatile and accurate

AI summary
A vehicle controller device is provided including a travel control section configured to control autonomous driving and remote driving, a biometric information acquisition section configured to acquire biometric information of an occupant, a state determination section configured to determine, based on the biometric information acquired by the biometric information acquisition section, whether or not an abnormality predicted state has arisen in which manual driving by operation by the occupant is predicted to become compromised and also whether or not an abnormal state has arisen in which manual driving is compromised, a notification section configured to notify an operation device of a determined state in cases in which either the abnormality predicted state or the abnormal state is determined to have arisen, and a reception section capable of receiving operation-ready information indicating that operation by a remote operator is possible from the operation device in response to the notification.
