Solution Overview

Problem

Conventional vehicle control systems do not adequately consider the behavior of vehicle occupants unrelated to vehicle operation when adjusting driving control, leading to insufficient adjustments in the driving control margin.

Innovation Solution

A vehicle control device and method that includes a recognizer for surrounding situations, a driving controller for steering and acceleration/deceleration, and a notifier for informing occupants, which sets a higher margin for the surrounding environment after notification, taking into account the behavior and interest of the vehicle occupant, and switches between driving modes to ensure appropriate control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the vehicle provides notification to the occupant about non-running information, then the occupant receives useful information, but the driving control margin is insufficient leading to safety risks

Engineering Contradiction:
Improveinformation provision to occupantVSAvoiddriving control safety
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The system dynamically adjusts the degree of margin for surrounding environment based on the notification state. When notification is active, the driving control margin is automatically increased to account for potential occupant distraction, creating a adaptive safety mechanism that responds to system state changes

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The driving controller proactively increases the driving control margin before potential safety issues arise by detecting when notification is provided to the occupant. This preliminary adjustment prevents safety problems by anticipating the impact of notification on occupant attention

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the vehicle maintains standard driving control margin, then the vehicle operates efficiently, but it cannot account for occupant behaviors unrelated to running

Engineering Contradiction:
Improvedriving efficiencyVSAvoidresponse to occupant behavior
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The driving control margin transitions from a static parameter to a dynamic one that automatically adjusts based on notification state, allowing the system to adapt to occupant behaviors while maintaining operational efficiency through automated adjustments

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The driving controller autonomously adjusts the driving control margin without requiring external input, automatically compensating for potential occupant distraction caused by notification and maintaining safety without manual intervention

Inventive Principle:
Principle #25Self-service

AI summary

A vehicle control device including: a recognizer (13) that recognizes a surrounding situation of a subject vehicle; a driving controller (140 or 160) that executes driving control of controlling one or both of steering and acceleration/deceleration of the subject vehicle on the basis of the surrounding situation recognized by the recognizer; and a notifier (30 or 180) that notifies a vehicle occupant of the subject vehicle of predetermined information, wherein the driving controller sets a degree of margin for a surrounding environment set in the driving control after start of the notification of the predetermined information using the notifier to be higher than that before start of the notification of the predetermined information.
