Remote Driving Terminal Pre-Check for Faster Vehicle Takeover

Solution Overview

Problem

Remote driving systems face delays in starting remote driving due to the time-consuming initial check process, which is necessary before initiating remote driving, especially in situations where rapid initiation is required.

Innovation Solution

The system detects a second situation indicative of a potential first situation and performs part of the initial check before the first situation occurs, allowing for early completion of the initial check and swift initiation of remote driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the initial check is performed only after the first situation is detected, then the system ensures safety and reliability by completing all necessary checks before starting remote driving, but the time required to start remote driving increases

Engineering Contradiction:

Improvesafety of remote driving initiationVSAvoidtime from detecting first situation to starting remote driving

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs a preliminary initial check when a second situation (showing a sign of the first situation) is detected, before the first situation actually occurs. This preliminary check includes acquiring vehicle state information and determining whether remote driving can be started, so that when the first situation occurs, the remote driving can begin immediately without waiting for the complete initial check process.

Inventive Principle:

Principle #10Preliminary action

2Speed

If the initial check process is shortened to enable faster remote driving initiation, then the response time improves, but the reliability and completeness of safety checks may be compromised

Engineering Contradiction:

Improvespeed of remote driving initiationVSAvoidcompleteness of initial check

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system performs a preliminary initial check when a second situation (showing a sign of the first situation) is detected, before the first situation actually occurs. This preliminary check includes acquiring vehicle state information and determining whether remote driving can be started, so that when the first situation occurs, the remote driving can begin immediately without waiting for the complete initial check process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The initial check process is divided into segments: a preliminary check performed when the second situation is detected (acquiring vehicle state information, determining startability), and a final confirmation performed when the first situation is detected. This segmentation allows parts of the check to be completed in advance while maintaining overall reliability.

AI summary

The present disclosure relates to a remote driving system that performs remote driving of a vehicle based on an operation amount input to a remote driving terminal. The remote driving system includes at least one processor. The at least one processor detects a second situation showing a sign of a first situation in which the remote driving of the vehicle is required. The at least one processor performs at least a part of an initial check for checking that the remote driving can be started at the remote driving terminal before the first situation is detected in a case where the second situation is detected. The at least one processor starts the remote driving in a case where the first situation is detected.
