Vehicle On-board System Non-voice Trigger for Voice Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in triggering customized vehicle system functions due to reliance on voice trigger conditions, which can be forgotten and require network connectivity, leading to poor user experience in abnormal network environments.
Innovation Solution
Implementing a non-voice trigger condition, such as the vehicle's door closure, to execute predefined instructions directly by the on-board system, even in abnormal network states, with voice feedback on execution results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice trigger condition is used for customized solution, then user can control multiple vehicle functions using simple voice, but user may forget the voice trigger condition and cannot trigger the customized solution
Solution Approach 1:
The patent inverts the traditional voice-triggered customization by introducing a door state trigger mechanism. Instead of requiring the user to actively speak a trigger phrase, the system automatically detects door closure state and triggers predefined customized solutions, thereby eliminating memory burden while ensuring reliable activation.
2Adaptability or versatility
If customized solution relies on network connection, then cloud voice server can process execution instructions, but vehicle cannot execute instructions in abnormal network environment
Solution Approach 1:
The patent applies preliminary action by pre-downloading and storing execution instructions locally in the vehicle before network disconnection occurs. When the door trigger condition is met, the on-board system can directly execute the stored instructions without requiring real-time network connection, ensuring reliable operation in abnormal network environments.
Solution Approach 2:
The patent implements local quality by distributing execution capability between cloud and on-board systems. The cloud voice server handles complex processing when network is available, while the on-board system independently executes pre-stored instructions when network is unavailable, allowing each component to operate optimally according to local conditions.
3Extent of automation
If all execution instructions are transmitted to cloud voice server, then centralized control can be achieved, but network dependency increases and execution time delays
Solution Approach 1:
The patent segments execution instructions into two categories: those requiring cloud processing and those that can be executed locally. By dividing the instruction set and assigning different execution locations, the system reduces network dependency and minimizes execution delays while maintaining appropriate levels of centralized control for complex operations.

AI summary
Disclosed is a voice interaction method, comprising: executing, by an on-board system, an execution instruction directly executable by a vehicle in a customized solution of an on-board system function, if the vehicle is in an abnormal network state when the customized solution satisfies a preset non-voice trigger condition; and providing voice feedback on an execution result of the execution instruction. The trigger condition of the customized solution is a non-voice trigger condition, and may be triggered under an abnormal network state as well. In an abnormal network state, the on-board system executes a portion of the execution instructions directly executable by the vehicle under the non-voice trigger condition, such that the customized solution is at least partially executed to satisfy a portion of the user's needs. After the instruction is executed, an execution result is fed back by voice, and the user may learn the implemented portion of the solution, thereby improving use experience of the customized solution under an abnormal network state to a certain extent. Further disclosed are a feedback apparatus, a vehicle, and a storage medium.
