Vehicle Function Settings via App Versioned Control Options
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle software update systems require complex processes such as downloading installation packages, user notification, and authorization, making it difficult to easily and quickly change the specifications of vehicle functions.
Innovation Solution
A vehicle function setting system that allows users to select and set control content for in-vehicle control devices using a mobile terminal application, with an in-vehicle storage device storing options for each version of the application, enabling quick specification changes without the need for factory maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional software update processes are used (downloading installation package, user notification, authorization), then software can be updated, but the process becomes complex and time-consuming
Solution Approach 1:
The control device stores multiple versions of control software in advance in its storage unit. When a update is needed, the system simply selects and activates a pre-stored software version rather than downloading and installing new software, thereby simplifying the update process while ensuring reliable software updates.
2Ease of operation
If conventional software update processes are used with user authorization requirements, then software updates can be controlled, but the update execution becomes slow and inconvenient
Solution Approach 1:
The control device autonomously manages software updates by automatically selecting appropriate software versions from stored versions based on vehicle operation states, without requiring user authorization or intervention. This self-service approach dramatically reduces update execution time and simplifies the operation process.
Solution Approach 2:
The system dynamically selects software versions based on real-time vehicle operation states (such as whether the vehicle is in a test mode or normal operation mode). This dynamic adaptation allows the system to switch between different software versions optimally without manual user input, improving both ease of operation and reducing time loss.
3Adaptability or versatility
If multiple software versions are stored for different application versions, then version compatibility is improved, but storage requirements increase
Solution Approach 1:
The control device's storage unit is designed to store multiple versions of control software that can serve multiple application versions. A single storage unit universally supports different software versions and their corresponding control parameters, eliminating the need for separate storage for each version and maintaining adaptability without proportionally increasing storage volume.

AI summary
A vehicle function setting system is configured to set at least one control content to be executed by an in-vehicle control device upon a provision of a predetermined function of the vehicle and includes a mobile terminal on which an application that enables a user to select the control content is installed, and an in-vehicle storage device that stores a plurality of options of the control content for each of a plurality of versions of the application. The mobile terminal allows the user to select the control content from the options corresponding to the version of the installed application, and sends information indicating the control content selected by the user to the in-vehicle control device. The in-vehicle control device acquires the control content corresponding to the information from the mobile terminal from the in-vehicle storage device.
