Tele-Operated Driving Request Timing for Vehicle Deadlocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in determining when to initiate a Tele-operated Driving (ToD) session reliably and automatically, as automated vehicles may encounter deadlock situations due to incorrect environment interpretation, sensor failures, or poor road conditions, making it difficult to identify the root cause of the issue.
Innovation Solution
A method involving the determination of a 'time-off' value based on the current driving situation, allowing the vehicle to wait before requesting a ToD session, which can be optimized using data categorization and analytics to filter out similar situations, and enabling manual override for quicker intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automated vehicle immediately requests ToD session upon detecting any issue, then response time is reduced, but false requests increase due to transient situations
Solution Approach 1:
The system performs preliminary analysis of the driving situation by categorizing sensor data and evaluating multiple conditions before initiating a ToD session request. This preliminary action filters out transient issues that would otherwise trigger false requests, while still maintaining rapid response to genuine deadlocks through pre-configured evaluation criteria.
2Reliability
If automated vehicle waits too long before requesting ToD session, then false requests are reduced, but response time to genuine deadlocks increases
Solution Approach 1:
The waiting period before ToD session initiation is not fixed but dynamically adjusted based on the evaluated driving situation. The system categorizes situations into different types (e.g., transient obstacles vs. genuine deadlocks) and applies different waiting periods accordingly, optimizing both false request reduction and response time for each situation type.
3Reliability
If manual override is always required for ToD session initiation, then false requests are reduced, but ease of operation decreases
Solution Approach 1:
The system performs self-service by automatically evaluating the driving situation, categorizing sensor data, and determining whether a ToD session request is warranted. This automated self-service reduces false requests while maintaining ease of operation, with manual override available only as a supplementary option for edge cases.

AI summary
The proposal corresponds to a method for invoking a Tele-operated Driving session ToD for a vehicle (10) equipped with an automated driving function, said vehicle (10) being equipped with a number of environment detection sensors (150, 151, 182, 186) and a communication module (160) for communicating to an external Control Center computer (320), The proposal further comprises a step of determining a time-off value for the vehicle (10) in which it needs to wait before a ToD session may be invoked, corresponding to the current driving situation the vehicle (10) is in. The proposal further comprises the sending of said ToD session request message from the vehicle (10) to said Control Center computer (320) once the waiting time according to the determined time-off value is over. The operator in the Control Center may then help to get the vehicle (10) out of the deadlock situation.
