Motor Vehicle Dialog System Dynamic Key Occupation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle dialog systems often fail to accommodate user preferences and habits due to limited control keys, leading to confusion when functions assigned to keys change unexpectedly, and users desire functions to be accessible across all system statuses without additional keys.
Innovation Solution
Implementing a process that allows multiple occupations of control keys for function groups, where functions are assigned based on the user's operating status, enabling a single key to perform multiple related functions such as switching on/off or adjusting parameters, with automatic assignment and status-dependent functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple functions are assigned to a single control key, then the number of control keys is reduced, but user confusion increases when functions change unexpectedly
Solution Approach 1:
The patent implements dynamic key occupation where control keys can be assigned to different functions based on the current dialog status. The key occupation changes dynamically as the user navigates through different menus and functions, allowing the same physical key to serve different purposes in different contexts. This resolves the contradiction by making the system adaptable rather than static.
Solution Approach 2:
The system changes the functional parameter of control keys based on the current operating status. When the dialog status changes (e.g., switching between radio control and navigation control), the assignment of functions to keys changes accordingly. This allows minimal hardware while providing context-appropriate functionality.
2Device complexity
If control keys are occupied by functions in manufacturer-configured dialog systems, then the system structure is simplified, but user preferences and habits are not accommodated
Solution Approach 1:
The system performs preliminary assignment of functions to keys based on manufacturer defaults, but also prepares the infrastructure for user customization. The dialog system includes mechanisms that allow users to later modify key occupations according to their preferences, combining structured design with user adaptability.
Solution Approach 2:
The system enables users to customize their own key occupations according to their personal habits and preferences. Users can assign functions to keys in a way that suits their usage patterns, and the system maintains these user-defined assignments across different dialog statuses.
3Ease of operation
If a control key is assigned to a function outside the current menu context, then function accessibility is improved, but system complexity increases
Solution Approach 1:
The patent implements universal control keys that can access functions regardless of the current menu context. A key assigned to a particular function (e.g., destination routing in navigation) can trigger that function even when the user is not currently in the navigation menu. The system manages this multi-functionality by maintaining status-dependent function assignments that work across different dialog states.

AI summary
In a dialog system for a motor vehicle having a plurality of control keys of which at least one can be occupied by several functions, one such control key can be occupied by several functions of a hierarchical menu structure that, when the control key is operated, as a function of an operating status of a use system coupled with the dialog system, precisely one of several functions is executed, and the occupation of the at least one control key by several functions takes place in that certain functions of the menu structure are assigned to a function group comprising several functions, and in that the control key is occupied by all functions assigned to the function group when one of the functions assigned to the function group is allocated to the control key by an operating action of the user.
