Automated Driving Start Control for Driver Readiness Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems transitioning from manual to automated driving often require specific operations that may not align with the driver's readiness, leading to potential inconvenience and safety risks due to erroneous starts.
Innovation Solution
A vehicle control device and method that allows automated driving to start without requiring specific operations at the time of switching from manual driving, based on predetermined operations identified at the traveling start time, and includes features to inhibit secondary tasks until a progress amount is reached, ensuring the driver is mentally prepared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specific operations are required at the time of switching from manual driving to automated driving, then safety is improved by preventing erroneous starts, but ease of operation deteriorates due to additional driver burden and potential inconvenience
Solution Approach 1:
The system performs preliminary verification by identifying specific operations that occur within a predetermined time period before the switching operation. This preliminary action ensures that the driver's intent is verified through recent operational context, allowing automated driving to start only when appropriate conditions are met, thus preventing erroneous starts while maintaining ease of operation.
Solution Approach 2:
The system provides feedback by monitoring and identifying operations performed by the driver within a predetermined time window. This feedback mechanism allows the control device to make informed decisions about whether to permit automated driving startup, balancing safety requirements with operational convenience by basing the decision on actual driver behavior patterns.
2Productivity
If automated driving starts immediately upon switching from manual driving, then productivity is improved by reducing transition time, but reliability deteriorates due to potential erroneous starts when driver is not mentally prepared
Solution Approach 1:
The system performs preliminary identification of specific operations within a predetermined time period before the switching operation. This preliminary verification ensures that the driver has performed relevant actions indicating readiness for automated driving, allowing the system to permit startup without significant delay while maintaining high reliability by preventing erroneous starts.
3Reliability
If specific operations are required at switching time, then reliability is improved by ensuring driver readiness, but loss of time increases due to additional verification steps
Solution Approach 1:
The system performs the verification of driver readiness in advance by identifying specific operations that occur within a predetermined time period before the switching operation. This preliminary action ensures that verification is based on recent driver behavior, establishing driver readiness without requiring additional verification time at the moment of switching, thus minimizing time loss while ensuring reliability.
Solution Approach 2:
The system continuously monitors driver operations within the predetermined time period, maintaining a running assessment of driver readiness. This continuous monitoring allows the system to have verification information ready when the switching operation occurs, eliminating the need for additional verification steps at switching time and thus reducing time loss while ensuring driver readiness.

AI summary
A vehicle control device identifies an operation received from a driver of a vehicle, and permits a traveling start by automated driving without a condition that a specific operation has been identified at a time of switching from manual driving to the automated driving, and permits the traveling start by the automated driving based on the specific operation at a traveling start time of the vehicle.
