Solution Overview

Problem

Existing vehicle control systems may not perform appropriate control during interruptions, such as when other vehicles cut into the path, as they do not account for various situations that may arise from non-automated driving vehicles in the vicinity.

Innovation Solution

A vehicle control device and method that includes a recognizer to identify surrounding situations, a driving controller to manage steering, acceleration, and deceleration independently of the driver, and a mode decider to switch between driving modes based on the presence of an interrupting vehicle and specific conditions, restricting the use of lighter task modes when certain conditions are met, such as excessive deceleration or proximity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the vehicle switches to a second driving mode with lighter driver tasks when automated driving is available, then productivity and ease of operation are improved, but reliability and safety deteriorate when interrupting vehicles are present

Engineering Contradiction:
Improveautomation efficiencyVSAvoidsafety during interruption
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts the driving mode based on real-time detection of interrupting vehicles. When an interrupting vehicle is detected during automated driving, the system transitions from the second driving mode (lighter driver tasks) to the first driving mode (heavier driver tasks), ensuring driver engagement and safety during potential collision risks.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The recognizer continuously monitors the surrounding environment for interrupting vehicles and provides feedback to the mode decider. This feedback mechanism enables the system to detect the presence of vehicles cutting into the travel path and appropriately adjust the driving mode to maintain safety while preserving automation efficiency during normal operation.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the vehicle maintains automated driving control during interruptions, then ease of operation is improved, but adaptability to various situations deteriorates

Engineering Contradiction:
Improvedriver workloadVSAvoidresponse to interrupting vehicles
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The driving mode is dynamically adjusted based on the presence of interrupting vehicles. The system maintains ease of operation through automated driving during normal conditions but adapts by requiring heavier driver tasks when interrupting vehicles are detected, ensuring appropriate response to various situations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of automated driving by switching between different driving modes. The mode decider adjusts the level of driver involvement based on detected conditions, allowing the system to maintain low driver workload during normal automated driving while increasing driver engagement when safety concerns arise from interrupting vehicles.

Inventive Principle:
Principle #35Parameter changes

AI summary

A vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle, a driving controller configured to control steering, acceleration, and deceleration of the vehicle independently of an operation of a driver of the vehicle, and a mode decider configured to decide on a driving mode of the vehicle as one of a plurality of driving modes including a first driving mode and a second driving mode. Implementation of the second driving mode is restricted when the interrupting vehicle is recognized and a prescribed condition is satisfied.
