Vehicle Dialogue System Master Subordinate Function Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dialogue systems for motor vehicles limit the functionality of control keys by either assigning only a parameter or both a function and parameter, lacking the ability to dynamically adjust to the vehicle's current state for executing functions that depend on its position.
Innovation Solution
A dialogue system where a control key is assigned a master function that determines the current vehicle state's parameter value, allowing execution of a subordinate function based on this value, enabling operations like searching for parking or services around the vehicle's location with a single key stroke.

Engineering Contradiction Analysis
1Adaptability or versatility
If a control key is assigned only a parameter or both function and parameter in conventional dialogue systems, then the system structure remains simple, but the functionality is limited and cannot dynamically adjust to the vehicle's current state
Solution Approach 1:
The patent segments the function execution into two distinct parts: a master function that determines current vehicle state parameters, and a subordinate function that executes the actual task using those parameters. This segmentation allows the control key to trigger complex state-dependent operations while maintaining a simple user interface.
Solution Approach 2:
The master function performs preliminary action by determining the current vehicle state parameters (such as position, speed, or other operational parameters) before the subordinate function is executed. This preliminary determination enables the subordinate function to operate with context-aware parameters without requiring complex real-time processing during the actual function execution.
2Productivity
If a control key is assigned a master function that determines current vehicle state, then multiple operations can be performed with a single key stroke, but the system complexity increases
Solution Approach 1:
The patent merges the parameter determination function and the task execution function into a single control key assignment. When the control key is activated, both the master function (parameter determination) and subordinate function (task execution) are triggered automatically, allowing multiple operations to be performed with a single user action.
Solution Approach 2:
The system performs self-service by automatically determining the current vehicle state parameters through the master function without requiring additional user input. The control key itself initiates the entire process, and the system autonomously completes the parameter determination and function execution sequence.
3Ease of operation
If functions depend on current vehicle position and state, then user convenience is enhanced, but the system requires more complex parameter determination mechanisms
Solution Approach 1:
The master function acts as an intermediary between the control key and the subordinate function. It translates the simple key activation into context-aware parameter determination, bridging the gap between user input and state-dependent function execution. This intermediary layer handles the complexity of parameter determination while presenting a simple interface to the user.

AI summary
In a dialogue system for a motor vehicle, the dialogue system including a plurality of control keys, assigning a function from a predefined set of functions to at least one of the control keys in such a manner that the function is executed upon actuation of the control key. At least one of the functions which can be assigned to the control key is configured as the master function. During the execution of the master function the current value of at least one parameter of a subordinate function that correlates with at least one state of the motor vehicle is determined, and the subordinate function is executed as a function of this value.
