Vehicle Speech Control Using Highlighted Neutral Command Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle with efficiently processing ambiguous neutral short speech commands, leading to delayed or incorrect activation of vehicle functions due to the inability to unambiguously determine the intended function.
Innovation Solution
A method utilizing speech recognition and graphical display to prioritize and distinctly mark the vehicle function that will react to a neutral short command, using predefined functions, sensor data, historical data, or user profiles to dynamically determine and highlight the prioritized function, allowing users to easily identify and activate the intended function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vehicle functions are displayed simultaneously on the screen, then the user can see all available functions, but it becomes difficult to quickly identify which function will respond to a neutral short command
Solution Approach 1:
The patent applies visual marking (highlighting) to the graphic representing the prioritized vehicle function that responds to neutral short commands. This graphical emphasis allows users to quickly identify which function will be activated by a neutral command like 'start' or 'launch' without having to read or analyze multiple function names, thereby resolving the contradiction between displaying multiple functions and enabling quick identification.
2Ease of operation
If neutral short commands are used for controlling vehicle functions, then the operation becomes simpler and faster, but the system cannot determine which function the user intends to activate
Solution Approach 1:
The system performs preliminary action by automatically prioritizing and visually marking the appropriate vehicle function before the user issues a neutral short command. Based on context information (time, location, vehicle state), the system pre-determines which function should respond to the neutral command and highlights it on the display. This allows the user to simply issue the neutral command without needing to specify which function they want, as the system has already prepared the correct function for activation.
3Productivity
If sequential processing of multiple vehicle functions is used, then all functions can be activated, but the desired function may be activated with delay or not at all
Solution Approach 1:
The visual marking on the display serves as an intermediary between the neutral short command and the vehicle function activation. When the user issues a neutral command like 'start', the system uses the visual marking to immediately identify which function should be activated, eliminating the need for sequential processing of multiple functions. This intermediary visual cue ensures that the desired function is activated immediately and accurately, preventing delays or incorrect activations.

AI summary
Speech inputs used to control vehicle functions in a vehicle, having speech recognition and having graphics, assigned to the vehicle functions, are displayed on a screen of the vehicle. Vehicle functions can be controlled by a neutral short spoken command that cannot be unambiguously related to a vehicle function so that the displayed graphic of the vehicle function directly reacting to the neutral short command is distinctively marked with respect to the simultaneously displayed graphics of the other vehicle functions.
