Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Automated assistants in vehicles often create user confusion by inconsistent value and unit displays across different system components, leading to a poor user experience and unnecessary computational resource consumption.

Innovation Solution

Implement a system that dynamically adapts the response of an automated assistant to spoken utterances by using an OEM query to enforce consistency between displayed values and units, and the values and units used in executing vehicular commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the automated assistant executes vehicular commands with high precision using specific conversion formulas, then the command execution accuracy is improved, but inconsistencies arise between displayed values and actual values causing user confusion

Engineering Contradiction:

Improvecommand execution accuracyVSAvoidvalue consistency

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The system implements feedback by querying the OEM component to obtain the actual value that will be set, then comparing this actual value with the displayed value. This feedback loop allows the system to detect and correct inconsistencies between what is shown to the user and what is actually executed, resolving the contradiction between precise command execution and value consistency.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system introduces an intermediary consistency check mechanism that acts as a mediator between the command execution process and the display system. This intermediary queries the OEM component for actual values and uses them to ensure displayed values match actual executed values, preventing user confusion while maintaining execution precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system uses different OEM-specific conversion formulas for processing vehicular commands, then the adaptability to different vehicle systems is improved, but inconsistencies in value displays occur across different manufacturers

Engineering Contradiction:

ImproveOEM system compatibilityVSAvoidvalue display consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system applies local quality by allowing each OEM component to use its own specific conversion formulas and processing methods tailored to its vehicle system, while the overall system maintains consistency through local queries to each OEM component. This enables adaptability to different OEM systems while ensuring value display consistency within each local context.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If the automated assistant provides detailed responsive output for each spoken utterance, then the user experience is improved, but computational resources are consumed unnecessarily when inconsistencies need to be resolved

Engineering Contradiction:

Improveuser experienceVSAvoidcomputational resource consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary action by querying the OEM component in advance to determine the actual value that will be set before providing responsive output to the user. This preliminary query allows the system to ensure consistency between displayed and actual values while maintaining efficient computational resource usage by only performing necessary queries.

Inventive Principle:

Principle #10Preliminary action

AI summary

Implementations described herein relate to determining how an automated assistant should respond to a given spoken utterance received in a vehicular environment to enforce consistency between value(s) and/or unit(s) that are displayed at a given display device of an in-vehicle computing device and value(s) and/or unit(s) that are utilized in executing a given vehicular command or that are provided for presentation to a user in response to a given vehicular request. For example, implementations can receive the given spoken utterance, identify the given vehicular command/request based on processing the given spoken utterance, and determine an original equipment manufacturer (OEM) query based on the given vehicular command/request included in the spoken utterance, and transmit the OEM query to a given OEM component. Further, implementations can determine how the automated assistant should respond to the given spoken utterance based on responsive content that is received from the given OEM component.
