Vehicle Control Device Anomaly Switch Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver anomaly management systems may execute unnecessary safety controls if they incorrectly determine that a driver cannot continue driving, leading to safety controls being executed at an improper time without the driver's recognition or consent.
Innovation Solution
A vehicle control device that includes an actuation unit to display an anomaly control switch on a touch display, allowing the driver to recognize and acknowledge the safety control content, and a controller that executes safety control only after the driver acknowledges the switch operation, thereby ensuring safety controls are executed at a proper time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver anomaly management system determines that the driver cannot continue driving appropriately, then safety control is executed, but the driver may not recognize the control content and the safety control may not be executed at a proper time
Solution Approach 1:
The system performs preliminary actions by displaying the control content of safety control to the driver before executing the safety control. This allows the driver to recognize and understand what control will be executed, ensuring informed consent while maintaining timely execution.
Solution Approach 2:
The system implements feedback by monitoring whether the driver has recognized the control content through the display, and only executes safety control after confirming the driver's awareness. This feedback mechanism ensures both driver recognition and proper timing of control execution.
2Reliability
If the driver anomaly management system executes safety control when the driver cannot continue driving, then safety is improved, but unnecessary safety control may be executed due to erroneous determination
Solution Approach 1:
The system uses feedback by requiring driver acknowledgment through the anomaly control switch before executing safety control. This additional feedback step verifies that the driver is indeed unable to continue driving, reducing erroneous executions while maintaining safety.
Solution Approach 2:
The anomaly control switch serves as an intermediary between the driver anomaly detection and safety control execution. It acts as a verification mechanism that confirms the driver's state before triggering safety control, preventing inadvertent execution.
3Ease of operation
If the anomaly control switch is not shown to the driver, then the system remains simple, but the driver cannot recognize the control content of safety control
Solution Approach 1:
The system uses the existing touch display for multiple purposes - both for normal vehicle operations and for displaying safety control content. This multi-functionality allows driver recognition of control content without adding separate display devices, maintaining system simplicity.
Solution Approach 2:
The control content is displayed as information on the touch display, creating a visual copy of the control instructions. This allows the driver to recognize the control content without physical switches or additional mechanical components.

AI summary
A vehicle control device includes an actuation unit that actuates an anomaly control switch that acknowledges execution of safety control, which improves safety during driving of a vehicle, upon detection of an occupant in an anomalous state from a monitoring result of a state of the occupant of the vehicle. The actuation unit causes the anomaly control switch to be actuated to allow the occupant to recognize a control content of the safety control. The vehicle control device further includes an operation acknowledgement unit that acknowledges operation of the anomaly control switch and a controller that executes the safety control when the operation acknowledgement unit acknowledges the operation of the anomaly control switch.
