Remote Control Requests for Autonomous Driving Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems face challenges when they encounter difficulties, necessitating a switch to remote control, which can overwhelm the limited number of available remote operators, leading to an undue burden.
Innovation Solution
A system that selectively employs remote assistance and remote driving based on the vehicle's ability to continue autonomous driving, allowing remote operators to make determinations or operate the vehicle as needed, reducing the burden by prioritizing autonomous driving when possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote driving is always requested when autonomous driving is difficult, then the autonomous driving vehicle can be controlled, but the burden on remote operators increases significantly
Solution Approach 1:
The patent segments remote control into two distinct types: remote assistance (for specific decision-making support) and remote driving (for full vehicle control). This segmentation allows the system to apply the appropriate level of remote intervention based on the situation, reducing unnecessary remote driving requests and thereby decreasing operator burden while maintaining control reliability.
Solution Approach 2:
The patent applies partial action by using remote assistance for only the specific determinations needed rather than requiring full remote driving control. When the autonomous driving vehicle encounters difficulty with specific decisions, only partial remote intervention is requested, which reduces the overall burden on operators while still resolving the control issues.
2Adaptability or versatility
If remote driving is requested frequently, then difficult driving situations can be handled, but the limited number of remote operators becomes overwhelmed
Solution Approach 1:
By segmenting remote control into remote assistance and remote driving, the system can handle difficult situations with minimal remote intervention. Remote assistance provides necessary support for specific decisions without requiring full remote driving takeover, thereby maintaining adaptability while preserving operator availability for when it is truly needed.
Solution Approach 2:
The autonomous driving vehicle attempts to handle difficult situations independently first, and only requests remote assistance or remote driving when necessary. This self-service approach reduces the frequency of remote operator engagement, preventing them from being overwhelmed while still maintaining the capability to handle difficult situations when they arise.
3Adaptability or versatility
If full remote driving control is used, then the vehicle can be controlled in any situation, but the operational complexity increases
Solution Approach 1:
The patent divides remote control into two distinct modes: remote assistance for specific determinations and remote driving for full control. This segmentation simplifies the operational complexity by providing clear guidelines for when to use each mode, reducing the cognitive load on operators and streamlining the control system's decision-making process.

AI summary
A remote control request method has requesting, by a computer (21), a remote operator (35,37) to perform remote control on an autonomous driving vehicle (20) when the autonomous driving vehicle (20) currently has or is expected to have difficulty in continuing autonomous driving, requesting remote assistance in which the remote operator (35) makes at least a part of determination for the autonomous driving inside an autonomous driving domain (ADD), and requesting, outside the autonomous driving domain (ADD), remote driving in which the remote operator (37) performs at least one of a steering operation and an acceleration or deceleration operation of the autonomous driving vehicle (20).
