Vehicle Panel Audio Interface for External Voice Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems lack the capability for effective human-machine interaction between people outside and inside a vehicle, particularly in scenarios requiring voice communication or alerts, due to the absence of software and hardware designed for such interactions.
Innovation Solution
A vehicle-mounted human-machine interaction system incorporating a piezoelectric sound-generating circuit, a wake-up subsystem, and an on-board controller that enables voice interaction by vibrating vehicle panels to emit sound externally and processes voice inputs from outside the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate systems (infotainment, navigation, communication) are used, then each system can be independently optimized, but the overall system complexity increases and control becomes cumbersome
Solution Approach 1:
The patent combines multiple separate systems (infotainment, navigation, communication, vehicle control) into a single integrated human-computer interaction system. The terminal device serves as a central hub that communicates with all subsystems through a unified interface, allowing users to control diverse functions through one device rather than multiple separate controls, thereby reducing overall system complexity and improving ease of operation.
Solution Approach 2:
The terminal device is designed with multi-functionality, serving as a universal controller for various vehicle systems including infotainment, navigation, communication, and vehicle parameter control. This single device performs multiple functions that would traditionally require separate systems, reducing the number of components needed and simplifying the overall system architecture.
2Adaptability or versatility
If multiple separate control systems are implemented, then each system can be independently controlled, but the integration and coordination between systems becomes complex
Solution Approach 1:
The terminal device acts as an intermediary between the user and multiple vehicle subsystems. It provides a unified interface that mediates control signals to various systems (infotainment, navigation, communication, vehicle controls) and coordinates their operations. This intermediary approach enables smooth integration and coordination of multiple systems while keeping the control architecture manageable and not overly complex.
3Ease of operation
If conventional interfaces are used, then implementation is straightforward, but user engagement and interaction quality remain limited
Solution Approach 1:
The system employs dynamic interaction modes including voice recognition, gesture control, and touch interface that adapt to user needs. The terminal device can switch between different interaction methods (speaking, gesturing, touching) depending on the situation, providing high-quality user engagement. While these dynamic features increase implementation complexity compared to conventional static interfaces, they significantly enhance user interaction quality and ease of operation.

AI summary
The present disclosure provides a vehicle-mounted human-machine interaction system. The vehicle-mounted human-machine interaction system includes: a piezoelectric sound-generating circuit disposed in a cavity between a body panel as an outer surface of a vehicle and an interior panel as an inner surface of the vehicle and attached to either the body panel or the interior panel; a wake-up subsystem configured to wake up an on-board controller to turn on a human-machine interaction function based on at least one of voices, movements, or images of objects outside the vehicle; and the on-board controller configured to output an audio signal to the piezoelectric sound-generating circuit after being woken up by the wake-up subsystem to turn on the human-machine interaction function such that as being excited by the audio signal, the piezoelectric sound-generating circuit vibrates the body panel or the interior panel to emit a voice to an exterior of the vehicle.
