Solution Overview

Problem

Vehicles undergoing remote autonomous driving may encounter failures, such as abnormal states or intrusions, leading to delays in transportation due to the need for manual intervention, especially when the distance between the vehicle and the operator is significant.

Innovation Solution

A control device that switches the driving mode from remote autonomous driving to remote manual driving when predetermined conditions are met, allowing operators to remotely control the vehicle using an operator input device, and includes a switching execution unit that transmits sensor and detection information to facilitate safe operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the vehicle runs in remote autonomous driving mode, then productivity is improved, but reliability deteriorates when failures occur

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidsystem reliability during failure
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically switches between remote autonomous driving mode and remote manual driving mode based on failure detection. When a failure is detected in the autonomous driving system, the control device automatically transitions to manual control mode, allowing operators to take over and resolve the issue, thus maintaining system reliability while preserving productivity during normal operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the operator stands by near the vehicle for manual intervention, then reliability is improved, but loss of time increases due to travel time

Engineering Contradiction:
Improveresponse capabilityVSAvoidtime to reach vehicle
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical approach of having operators physically stand by or travel to the vehicle with a remote control system. Operators can control the vehicle from a distance using communication networks, eliminating the need for physical proximity while maintaining the ability to intervene manually when failures occur, thus reducing time loss without compromising reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If the vehicle stops during remote autonomous driving, then safety is improved, but productivity deteriorates due to conveyance delay

Engineering Contradiction:
Improvesafety during failureVSAvoidconveyance speed
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system implements continuous monitoring and feedback mechanisms to detect failures during remote autonomous driving. When a failure is detected, the system provides feedback to switch to remote manual driving mode, allowing operators to assess the situation and determine whether stopping is necessary. This feedback loop enables safety-critical stops while minimizing unnecessary interruptions to productivity.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If remote manual driving mode is implemented, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvedriving mode flexibilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control device is designed with multi-functionality, serving as the central hub for both remote autonomous driving control and remote manual driving control. The same control device communicates with both the autonomous driving system and the operator input devices, eliminating the need for separate control systems and reducing overall device complexity while maintaining adaptability across different driving modes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A technique that can prevent conveyance of a moving object from delaying when the moving object stops during autonomous driving by a remote operation. A control device includes a switching execution unit that, when a predetermined first switching condition is satisfied, switches a driving mode of the moving object from a remote autonomous driving mode to a remote manual driving mode, and the first switching condition includes as a condition a case where, during running in the remote autonomous driving mode, the moving object falls in at least one state of (1a) a first state where a state of the moving object has become an abnormal state, (1b) a second state where a moving object has intruded a surrounding area set in advance to surroundings of the moving object, and (1c) a third state where a failure has occurred during the running in the remote autonomous driving mode.
