Vehicle Software Update Control Based on Cabin Occupancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle software update systems cannot differentiate between occupied and unoccupied vehicles, leading to software updates being initiated during times when users want to use the vehicle, causing inconvenience.
Innovation Solution
An information processing device for vehicles that detects the presence of occupants using pressure sensors and notifies them before starting software updates, allowing occupants to choose when to initiate the update, and automatically updates the software when no occupants are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software update is performed automatically without occupancy detection, then update reliability is improved, but user convenience deteriorates because updates may start when users want to use the vehicle
Solution Approach 1:
The system performs preliminary detection of occupant presence before initiating the software update process. By checking whether the vehicle cabin is occupied before starting the update, the system可以避免 initiating updates when users are present, thereby maintaining both update reliability and user convenience
2Ease of operation
If software update is delayed to avoid occupying vehicle usage, then user convenience is improved, but update timeliness deteriorates
Solution Approach 1:
The system dynamically adjusts the update execution timing based on real-time occupancy detection. When the vehicle is detected to be unoccupied, the update proceeds immediately, ensuring timeliness. When occupants are present, the update is postponed, ensuring user convenience. This dynamic adaptation resolves the contradiction between convenience and timeliness
3Ease of operation
If occupancy detection and notification system is added, then user convenience is improved, but device complexity increases
Solution Approach 1:
The notification device is designed to serve multiple functions: it notifies users of upcoming updates, informs them of update status, and can interact with the occupancy detection system. By making the notification device multi-functional, the system achieves improved user convenience without proportionally increasing overall system complexity

AI summary
An information processing device is for a vehicle. The information processing device includes one or more processors configured to: receive update software for an electronic control device mounted on the vehicle; perform an update of software of the electronic control device to the update software; determine whether an occupant is present in a vehicle cabin of the vehicle; make a notification before update to the update software is started when determining that the occupant is present in the vehicle cabin, the notification being made to allow the occupant to select whether to start the update to the update software; and start the update to the update software without making the notification when determining that no occupant is present in the vehicle cabin.
