Vehicle Update Progress Screen Control for Fewer Approval Steps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle electronic control systems require frequent user intervention for program updates, leading to a cumbersome experience due to multiple screen displays for approval operations during the program rewriting process.
Innovation Solution
A vehicle master device instructs a rewrite target ECU to write update data and manages screen display instructions based on a customization mode set by the user, allowing the display terminal to show a progress screen according to the update phase and user settings, thereby simplifying the approval process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system displays multiple approval screens during program update, then the user can control each update phase, but the operation process becomes cumbersome and time-consuming
Solution Approach 1:
The patent applies dynamics by making the display behavior adaptive based on user customization settings. The system dynamically adjusts between displaying multiple approval screens (for reliability) and displaying fewer screens (for ease of operation) based on the customization mode determination. This resolves the contradiction by making the system flexible rather than fixed in its display behavior.
Solution Approach 2:
The patent changes the parameter of screen display quantity based on the customization mode. When customization mode is enabled, the system changes the display parameter to show consolidated approval screens; when disabled, it shows detailed phase-by-phase screens. This parameter change allows the system to adapt between reliability and ease of operation requirements.
2Reliability
If the system requires frequent user approval during program update, then the update process is more controlled, but the update time increases
Solution Approach 1:
The system dynamically adjusts the approval frequency based on customization mode settings. In customization mode, the system reduces approval frequency by consolidating displays, thereby reducing update time while maintaining essential control. This dynamic adjustment resolves the contradiction between controlled updates and update duration.
Solution Approach 2:
The system performs preliminary action by determining the customization mode before executing the update process. This preliminary determination allows the system to pre-configure the appropriate display strategy, avoiding unnecessary approval screens when customization mode is enabled, thus reducing update time while preserving necessary controls.
3Loss of information
If the system provides detailed progress screens for each update phase, then the user has full information, but the display complexity increases
Solution Approach 1:
The patent changes the display information parameter based on customization mode. When customization mode is enabled, the system consolidates information display to reduce complexity. When disabled, it provides detailed phase-by-phase information. This parameter change resolves the contradiction between information completeness and display complexity.
Solution Approach 2:
The display complexity dynamically adjusts based on user preferences stored in customization mode. The system becomes simpler when customization is enabled and more detailed when it is disabled, allowing users to balance information completeness against display complexity according to their needs.

AI summary
A vehicle electronic control system includes a mode determination unit that is configured to determine whether a customization mode for a screen display related to an approval to a program update is set through a user's customization operation, and a screen display instruction unit that is configured to instruct the display terminal to display a progress screen of the program update according to a current update phase and a setting of the customization mode when the mode determination unit determines that the customization mode is set and instruct the display terminal to display the progress screen of the program update according to the current update phase and an initial setting when the mode determination unit determines that the customization mode is not set. The display terminal is configured to display the progress screen of the program update as instructed by the screen display instruction unit.
