Solution Overview

Problem

Existing vehicle control systems face interference issues when drivers touch the steering wheel during autonomous emergency avoidance steering, hindering the vehicle's ability to avoid obstacles effectively.

Innovation Solution

A vehicle control device that outputs a notification command to urge the driver to avoid touching the steering wheel by using a combination of visual, auditory, and vibratory notifications to prevent interference with autonomous emergency avoidance steering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vehicle executes autonomous emergency avoidance steering when detecting an obstacle, then the vehicle can avoid the obstacle effectively, but the driver may touch the steering wheel and interfere with the autonomous steering operation

Engineering Contradiction:

Improveobstacle avoidance effectivenessVSAvoiddriver interference with steering

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The notification unit issues a notification command to the driver before the autonomous emergency avoidance steering is executed, urging the driver to avoid touching the steering wheel. This preliminary action prevents the driver from interfering with the autonomous steering operation while maintaining the vehicle's ability to avoid obstacles effectively.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If the vehicle provides notification to the driver about autonomous emergency avoidance steering, then the driver is aware of the situation, but the notification may not be sufficient to prevent the driver from touching the steering wheel during critical moments

Engineering Contradiction:

Improvedriver awareness of autonomous steeringVSAvoiddriver steering wheel contact

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The notification is issued in advance before the autonomous emergency avoidance steering begins, giving the driver time to release the steering wheel before the critical maneuver starts, thereby preventing interference while maintaining driver awareness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notification command serves as a preliminary anti-action by urging the driver to avoid touching the steering wheel, counteracting the potential harmful action of driver contact before it can interfere with the autonomous steering operation.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A vehicle control controller is configured to acquire information on an obstacle in front of a vehicle acquired by an external world recognition device, and to output, based on the acquired obstacle position and own vehicle position, a first notification command for controlling a notification unit so as to give to a driver a notification for urging the driver to avoid touching a steering wheel when transitioning to an autonomous emergency avoidance steering mode for avoiding the obstacle based on control by an electric power steering device.
