Remote Driving Feedback Recording for Critical Vehicle Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving systems, remote operators cannot always verify the outcome of their instructions, particularly in situations requiring recording, such as emergency braking, due to lack of real-time feedback.
Innovation Solution
A vehicle remote instruction system that includes a recording required situation determination unit and a remote instruction result recording unit to record position information and detection data from vehicle-mounted sensors when specific conditions, like emergency braking, are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the remote operator gives a remote instruction to the autonomous driving vehicle, then the vehicle can perform traveling according to the instruction, but the operator cannot always know the result of the remote instruction
Solution Approach 1:
The system determines in advance whether the autonomous driving vehicle is in a recording-required situation before the remote instruction is executed. This preliminary determination ensures that when the instruction is given, the system is already prepared to record the result if needed, eliminating the information loss without requiring complex real-time monitoring infrastructure.
Solution Approach 2:
The system provides feedback to the remote operator by recording the result of the remote instruction when the vehicle is in a recording-required situation. This feedback mechanism allows the operator to know the outcome of their instructions in critical situations while maintaining system simplicity by not requiring continuous feedback for all operations.
2Loss of information
If the system records the result of remote instruction in all situations, then complete information is available, but unnecessary recording increases data storage requirements
Solution Approach 1:
The system applies different recording qualities to different situations: in recording-required situations (such as emergency braking), the system records complete result information, while in normal situations, no recording is performed. This localized approach ensures complete information is available when needed without the overhead of universal recording.
Solution Approach 2:
Instead of recording in all situations (excessive action) or never recording (insufficient action), the system performs partial recording only when the vehicle is determined to be in a recording-required situation. This partial action approach captures sufficient information for accountability while minimizing data storage requirements.
3Measurement precision
If the system determines recording required situations based on vehicle sensor data, then accurate recording decisions are made, but processing time increases
Solution Approach 1:
The determination of whether the vehicle is in a recording-required situation is performed in advance of the remote instruction execution. This preliminary action allows the system to have the determination result ready when the instruction is given, providing accurate recording decisions without adding time delays to the instruction-response cycle.

AI summary
A vehicle remote instruction system is a system in which a remote operator performs a remote instruction relating to travel of an autonomous driving vehicle according to a situation of the autonomous driving vehicle. The system includes: a recording required situation determination unit configured to determine whether or not the autonomous driving vehicle traveling according to the remote instruction is in a predetermined recording required situation, based on detection information from a vehicle-mounted sensor of the autonomous driving vehicle, if the remote operator performs the remote instruction on the autonomous driving vehicle; and a remote instruction result recording unit configured to record position information of the autonomous driving vehicle as a result of the remote instruction, if it is determined by the recording required situation determination unit that the autonomous driving vehicle is in the recording required situation.
