Vehicle Program Update Scheduling During Planned Stop Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems for autonomous driving vehicles lack an efficient method to update programs at appropriate timings, potentially disrupting vehicle operations during updates.
Innovation Solution
An information processing device with a control unit that acquires program update information and formulates a plan to update the program while the vehicle is stopped, ensuring safety and minimizing operational disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If program updates are performed during vehicle operation, then system functionality can be improved continuously, but vehicle safety and operational stability deteriorate due to potential disruptions during travel control
Solution Approach 1:
The control center formulates an update plan in advance that schedules program updates to occur only during predetermined stop time zones. This preliminary planning ensures that updates are performed proactively during maintenance periods rather than reactively during operation, preventing disruptions to travel control and maintaining vehicle safety while enabling continuous system improvement
Solution Approach 2:
The operation plan is segmented into distinct time zones: operation time zones for vehicle travel and stop time zones for maintenance activities. By dividing the operational timeline and assigning updates exclusively to stop time zones, the system separates update operations from travel control operations, eliminating the risk of interference while maintaining both update capability and operational safety
2Reliability
If program updates are scheduled during vehicle stop periods, then operational safety is maintained, but update frequency and productivity decrease due to limited available time windows
Solution Approach 1:
The control center receives update completion notifications from the vehicle and uses this feedback to dynamically adjust future update plans. When updates are completed successfully during stop time zones, the system learns from this feedback and can optimize subsequent update scheduling, potentially increasing update frequency over time while maintaining the safety constraint of performing updates only during stop periods
Solution Approach 2:
The update plan is not static but dynamically adjusted based on actual vehicle operation patterns and update completion status. The control center formulates updated plans that adapt to changing stop time zone availability, allowing the system to maximize update frequency within the constraints of safe operation by flexibly utilizing available maintenance windows
