Solution Overview

Problem

Existing automated driving technologies do not adequately address vehicle control and occupant notification during a lane change when an incoming call is received, leading to potential inappropriate vehicle control based on the timing of lane changes and calls.

Innovation Solution

A vehicle control device and method that includes a recognizer to identify the vehicle's surroundings, a driving controller to manage steering and speed, an incoming call determiner to detect calls, and a notification controller to provide occupant information, allowing for appropriate lane change decisions based on the progress of control and call importance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the vehicle executes lane change control during automated driving, then the vehicle can change lanes to reach the destination, but if an incoming call is received during the lane change, the timing and appropriateness of vehicle control may become inappropriate

Engineering Contradiction:
Improvelane change execution efficiencyVSAvoidvehicle control appropriateness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system determines in advance whether to suppress lane change control when an incoming call is detected. By checking the degree of progress of lane change control before executing the lane change, the system can proactively prevent inappropriate vehicle control actions, ensuring reliability while maintaining productivity when conditions are appropriate.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the vehicle suppresses lane change when an incoming call is present, then vehicle control appropriateness is improved, but the lane change may be delayed causing loss of time

Engineering Contradiction:
Improvevehicle control appropriatenessVSAvoidlane change completion time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system uses the degree of progress of lane change control as a dynamic parameter to determine whether to suppress the lane change. When the degree of progress indicates the lane change is nearly complete or already completed, the system allows the lane change to proceed even during an incoming call, thereby minimizing time loss while maintaining control appropriateness.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If the notification controller provides detailed information about vehicle operation and incoming call, then information completeness is improved, but the notification system complexity increases

Engineering Contradiction:
Improveinformation completenessVSAvoidnotification system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The notification controller segments information presentation by using different notification modes based on the driving control state. It provides different levels of information detail depending on whether lane change control is being executed, suppressing, or has completed, thereby maintaining information completeness while avoiding unnecessary complexity in the notification system.

Inventive Principle:
Principle #1Segmentation

AI summary

A vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle, a driving controller configured to execute driving control for controlling one or both of steering and a speed of the vehicle, an incoming call determiner configured to determine presence or absence of an incoming call for an occupant of the vehicle, and a notification controller configured to notify the occupant of information about an operation of the vehicle based on the driving control and information about the incoming call in a mode corresponding to a state of the driving control. The driving controller determines whether or not to make a lane change from a travel lane of the vehicle to an adjacent lane on the basis of a degree of progress of the control if the incoming call is present when control related to the lane change of the vehicle is executed.
