Solution Overview

Problem

In autonomous vehicles, interference between user operations and autonomous driving system operations for doors and windows can lead to uncertainty about whether a stopped operation is a continuous or new request, causing operational confusion.

Innovation Solution

An autonomous driving system transmits an 'operation command indicating no request' to a vehicle control interface box when control interference occurs, allowing the interface box to differentiate between continuous and new requests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the autonomous driving system continues transmitting operation commands without interruption, then the system maintains continuous control authority, but the vehicle control interface box cannot distinguish between continuous requests and new requests after operation stoppage

Engineering Contradiction:
Improvecontrol command accuracyVSAvoidrequest status information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The autonomous driving system transmits a preliminary 'no request' command before potentially issuing new commands after operation stoppage. This preliminary action resets the command state in the vehicle control interface box, enabling it to distinguish subsequent new requests from continuous requests. The 'no request' command serves as a state-clearing signal that prepares the system for unambiguous command interpretation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the vehicle control interface box receives multiple operation commands during interference, then it processes all incoming commands, but operational confusion occurs due to inability to determine command priority and timing

Engineering Contradiction:
Improvecommand processing throughputVSAvoidcommand interpretation clarity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The 'no request' command acts as an intermediary signal between the autonomous driving system and the vehicle control interface box during interference scenarios. This intermediary command clears the command buffer state and establishes a clear temporal boundary, allowing the interface box to process subsequent commands without confusion about their origin or priority. The intermediary signal resolves the ambiguity without reducing overall command processing capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An ADK determines whether or not a subject device has stopped operation due to control interference caused by a user operation and an ADK operation that were simultaneously performed. When the ADK determines that the subject device has stopped operation due to control interference caused by the user operation and the ADK operation that were simultaneously performed, the ADK transmits to a VP (VCIB), a control request (an operation command) indicating “no request (No request)” corresponding to the subject device that has stopped operation.
