Vehicle Cabin Control Flow Using Time-Segmented Mode Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control devices for vehicle cabin environments impose a significant development burden when designing control flows for multiple operation devices across different modes.
Innovation Solution
A control device that includes a memory to store mode setting values and a processor to execute control periods based on these values, allowing for consistent control flows across first and second modes by specifying operation devices and their contents for each period.

Engineering Contradiction Analysis
1Adaptability or versatility
If control flows for multiple operation devices are designed for each mode, then different vehicle cabin environments can be achieved, but the development burden increases excessively
Solution Approach 1:
The control flow is segmented into multiple periods (first period, second period, etc.) with each period having specific operation devices and operation contents. By dividing the overall control process into time-based segments, the system can achieve different vehicle cabin environments through period configuration rather than creating entirely separate control flows for each mode, thereby reducing development burden.
Solution Approach 2:
The control device dynamically switches between different periods based on the elapsed time from the start of control. The processor automatically transitions from the first period to the second period when the first period's length has elapsed, enabling adaptive control that responds to time-based conditions without requiring manual intervention or complex mode-specific programming.
2Adaptability or versatility
If mode-specific control flows are created, then different operation contents can be specified for first mode and second mode, but the control system complexity increases
Solution Approach 1:
A single control flow structure serves multiple modes (first mode and second mode) by incorporating both periods within the same control sequence. The processor executes the same control flow regardless of which mode is active, but differentiates behavior through period configuration, allowing one control system to fulfill multiple functional requirements without increasing complexity.
Solution Approach 2:
The control device pre-configures multiple periods with their respective operation devices and operation contents before execution. The processor stores the length of each period in advance and automatically determines when to transition between periods based on elapsed time, eliminating the need for real-time decision logic and reducing control system complexity.

AI summary
A control device that controls operation devices mounted in a vehicle includes a memory and a processor. The memory stores a mode setting value set. In the mode setting value set, information indicating a length of a first period, information indicating an operation device that is the target to be operated during the first period, information indicating an operation content of the operation device that is the target to be operated during the first period, information indicating an operation device that is the target to be operated during a second period following the first period, and information indicating an operation content of the operation device that is the target to be operated during the second period are determined corresponding to each mode. The processor executes the control based on the information corresponding to each mode.
