In-Vehicle Control Apparatus Driver Anomaly Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle control systems delay in implementing safety measures when a driver becomes unable to drive due to a sudden illness, as they rely on external alarms and hazard avoidance processes that may not promptly address the driver's inability to recover.
Innovation Solution
An in-vehicle control apparatus that monitors the driver's state and activates an alarm outwardly from the vehicle before initiating the hazard avoidance process, ensuring safety measures are taken promptly if the driver is unlikely to recover, by using a combination of cameras, sensors, and a microcomputer to determine the driver's inability to drive and control vehicle behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system issues an alarm outwardly from the vehicle and simultaneously performs hazard avoidance process, then safety measures are implemented, but the response time is delayed due to confirmation procedures
Solution Approach 1:
The system issues the alarm outwardly from the vehicle immediately when driver inability is determined, before completing the full hazard avoidance process. This preliminary action alerts other vehicles and pedestrians in advance, reducing the overall response time while maintaining safety through staged intervention.
Solution Approach 2:
The system implements a dynamic, multi-stage response: first issuing the alarm outwardly, then proceeding with hazard avoidance only if the driver does not respond within a specified time. This dynamic approach adapts the intensity of intervention based on driver response, optimizing both speed and safety.
2Reliability
If the system confirms driver response through audiovisual notification before taking measures, then false alarms are reduced, but the time to implement safety measures increases
Solution Approach 1:
The system performs preliminary confirmation through audiovisual notification to the driver before issuing the outward alarm and executing hazard avoidance. This preliminary check ensures the driver anomaly is real while minimizing delay by using quick sensory notifications rather than lengthy verification procedures.
Solution Approach 2:
The system rushes through the confirmation process by using direct audiovisual notifications that require minimal driver interaction, rather than requiring complex responses. This allows rapid verification of driver awareness while maintaining accurate anomaly detection.
3Reliability
If the system performs hazard avoidance process immediately after determining driver inability, then accident risk is reduced, but unnecessary intervention occurs if driver recovers
Solution Approach 1:
The system uses a dynamic, conditional approach where hazard avoidance is triggered only if the driver does not respond to the alarm within a specified time. This allows the system to adapt to driver recovery or correction of the anomaly, preventing unnecessary intervention while maintaining high accident prevention capability.
Solution Approach 2:
The system incorporates feedback from driver response to the alarm before executing hazard avoidance. If the driver responds or corrects their condition, the system cancels the hazard avoidance process. This feedback mechanism ensures appropriate intervention only when necessary, balancing accident prevention with driver autonomy.

AI summary
An in-vehicle control apparatus performs a hazard avoidance process. The in-vehicle control apparatus includes an anomaly determination section, an alarm control section, and a hazard avoidance control section. The anomaly determination section determines whether a driver is under driving inability state during travel of the vehicle, based on information on monitoring of state of the driver. The alarm control section activates an alarm annunciator to issue an alarm outwardly from the vehicle when the driver is determined to be under driving inability state. After the alarm annunciator starts the alarm, the hazard avoidance control section fails to perform the hazard avoidance process when the alarm is stopped by a manipulation of the driver and performs the hazard avoidance process when a specified time elapses under state where the alarm is not stopped since the starting of the alarm.
