Driver Observation Device for Autonomous Mode Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems fail to seamlessly transition from driver-controlled to autonomous or highly automated modes when a driver becomes tired or distracted, potentially leading to safety hazards due to the lack of immediate intervention in critical driving situations.
Innovation Solution
A driver observation device, utilizing cameras, sensors, and data cloud connectivity, monitors driver attentiveness and health status to automatically switch the vehicle to an autonomous or highly automated mode, enabling actuator control for longitudinal and transverse movement, and signaling changes in direction or warning surroundings of impending maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle operates in driver-controlled mode, then the driver maintains full control over vehicle movement, but safety is compromised when the driver becomes tired or distracted
Solution Approach 1:
The driver observation device automatically monitors the driver's state and triggers autonomous mode activation without requiring driver input. The system serves itself by detecting driver incapacity and autonomously switching operating modes, eliminating the need for driver self-assessment and manual mode switching.
Solution Approach 2:
The system continuously monitors driver state through the driver observation device and uses this feedback to dynamically adjust the operating mode. When the driver is detected to be tired or distracted, the system feedback loop triggers a mode transition to autonomous operation, ensuring safety while maintaining driver control when appropriate.
2Reliability
If the vehicle transitions to autonomous mode immediately when driver incapacity is detected, then safety is improved, but driver awareness and control transition may be compromised
Solution Approach 1:
The system activates auxiliary devices before the full autonomous mode transition is complete. This preliminary activation of safety systems ensures that protective measures are in place during the transition period, maintaining safety while the driver becomes aware of and adapts to the mode change.
Solution Approach 2:
The operating mode is not switched instantaneously but transitions dynamically over time. The vehicle controlling over automatically adjusts the degree of automation based on the driver's current state, allowing for a gradual transition that maintains driver awareness while improving safety progressively.
3Measurement precision
If driver observation using cameras and sensors is implemented, then driver state detection accuracy is improved, but device complexity increases
Solution Approach 1:
The driver observation device performs multiple functions using a single integrated system. It detects driver attentiveness, monitors health status, determines operating mode requirements, and triggers safety interventions. This multi-functionality reduces the need for separate specialized devices while maintaining high measurement precision.
Solution Approach 2:
Multiple detection functions are merged into a single driver observation device that uses cameras and sensors to simultaneously assess various aspects of driver state. By combining these functions in one integrated system rather than using separate devices, the overall device complexity is reduced while maintaining comprehensive monitoring capability.

AI summary
A device and to a method for controlling a vehicle, the vehicle being capable of being operated in a first operating state in which the vehicle is controlled by the driver with regard to its movement, and being capable of being operated in a second operating state in which the vehicle is guided autonomously or at least in highly automated fashion without intervention by the driver with regard to its movement, a driver observation device being provided that detects the ability of the driver to drive, and, when inability of the driver to drive is recognized, automatically changes over the vehicle controlling from the first operating state to the second operating state.
