Vehicle Software Update Guidance for Visual and Audio Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle software update systems fail to effectively notify occupants, particularly elderly individuals, of software updates when the vehicle is parked or stopped, as they may not visually recognize notifications, and displaying updates while the vehicle is traveling is undesirable.
Innovation Solution
A vehicle software update apparatus that includes an update control device and an input and output control device, which performs a visual ability determination process to decide between displaying guidance notifications on a display device and outputting audio notifications, ensuring that occupants are informed of software updates without interrupting their use of the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual notification is displayed on the display device, then the notification is clear and readable, but elderly occupants with poor visual ability cannot recognize it
Solution Approach 1:
The patent replaces the visual notification mechanism with an audio notification mechanism. When the system detects that the vehicle is stopped and the notification period has elapsed, it outputs audio notifications from the sound output device instead of relying solely on visual display, thereby accommodating occupants with poor visual ability while maintaining clear notification delivery.
2Loss of information
If software update notification is displayed while the vehicle is traveling, then the notification can be provided to the occupant, but it interrupts the occupant's use of the vehicle and reduces safety
Solution Approach 1:
The patent implements dynamic control of notification display based on vehicle operation state. The notification display is enabled only when the vehicle is in a stopped state, and automatically disabled when the vehicle starts traveling. This dynamic adjustment ensures that notifications are delivered when safe to do so, without interrupting the occupant's use of the vehicle during operation.
3Measurement precision
If the notification is displayed for a long period, then elderly occupants have time to recognize it, but the notification remains visible during vehicle travel which is unsafe
Solution Approach 1:
The patent implements periodic notification delivery with specific timing control. The notification is displayed for a predetermined period when the vehicle is stopped, then hidden. If the vehicle remains stopped after the period elapses, the audio notification is activated. This periodic approach ensures adequate recognition time for elderly occupants while automatically preventing notification display during vehicle travel, eliminating safety hazards.

AI summary
A vehicle software update apparatus includes an update control device and an input and output control device. Before performing a process of updating software of a vehicle, the update control device: determines a visual ability of an occupant on board the vehicle to view guidance display of the software update process for the vehicle; displays a guidance notification of the software update process on a display device via the input and output control device, upon a determination that the occupant has the ability to view the guidance display; and displays the guidance notification of the software update process on the display device via the input and output control device, and outputs an audio guidance notification of the software update process from a sound output device via the input and output control device, upon a determination that the occupant does not have the ability to view the guidance display.
