Automated Driving Route Confirmation Through Timed Driver Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During automated driving without a monitoring obligation, there is a risk of degradation in convenience due to the difficulty in identifying the driver's intended driving route when route guidance is not provided, leading to potential deviations from the intended route.
Innovation Solution
A vehicular control device and method that includes a guidance provision determination unit to assess whether route guidance is underway and a notification control unit to prompt confirmation or situation notifications at predetermined times when route guidance is not provided, allowing the driver to confirm if they are following their intended route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated driving without monitoring obligation is implemented, then driver workload is reduced, but route confirmation capability deteriorates
Solution Approach 1:
The system provides feedback to the driver about the current traveling situation and route status through notifications. The notification control unit outputs notifications to inform drivers of their intended route and current position, creating a feedback loop that maintains route confirmation capability even when the driver is not actively monitoring the vehicle.
Solution Approach 2:
The system performs preliminary action by proactively notifying drivers about their intended route before potential route deviations occur. The guidance provision determination unit determines the intended route in advance, and the notification control unit prepares and outputs route confirmation notifications at appropriate timings to prevent rather than correct route errors.
2Device complexity
If route guidance is not provided during automated driving, then system simplicity is improved, but route accuracy deteriorates
Solution Approach 1:
The automated driving system performs self-service by autonomously determining the intended route based on navigation information and continuously monitoring its own traveling situation. The guidance provision determination unit uses the vehicle's current position and navigation data to self-determine the intended route without requiring additional manual input or complex external guidance systems.

AI summary
A vehicular control device with which automated driving without a monitoring obligation is performed includes: a guidance provision determination unit that determines whether route guidance to a destination set by an occupant of the vehicle is under way; and a notification control unit that when the guidance provision determination unit determines that the route guidance is not under way during the automated driving without a monitoring obligation of the vehicle, causes prompting notification, which is at least either confirmation notification prompting confirmation related to setting of a route or situation notification notifying of a traveling situation, at a predetermined timing.
