Solution Overview

Problem

Existing 'visible and speakable' technologies for vehicle interaction are too single and require high development costs, limiting effective control of applications and failing to enhance user experience and driving safety.

Innovation Solution

A method and apparatus that differentiate between first-type and second-type applications, using either a preset software development kit or system service to obtain interface information and execute instructions based on semantic text, allowing flexible selection of solutions for diverse applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single existing 'visible and speakable' processing flow is used, then the system is simple to implement, but it requires large development costs and cannot achieve effective control of diverse applications

Engineering Contradiction:
Improveapplication control capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the application ecosystem into two distinct categories: first-type applications that integrate the voice client directly, and second-type applications that use system services. This segmentation allows each type to be handled with appropriate methods, improving overall adaptability without overwhelming system complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal processing framework that can handle both first-type and second-type applications through a common architecture. The system universally processes interface information and semantic text regardless of application type, while adapting execution methods based on the specific type

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If a unified processing method is used for all applications, then the system architecture is simple, but it cannot effectively control different application types and requires high development costs

Engineering Contradiction:
Improveimplementation costVSAvoidapplication compatibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by assigning different processing characteristics to different application types. First-type applications receive direct voice client processing, while second-type applications receive system service processing. This localized adaptation reduces overall implementation costs while maintaining broad application compatibility

Inventive Principle:
Principle #3Local quality

3Reliability

If traditional voice control methods are used, then the implementation is straightforward, but the driver must focus on settings and buttons, reducing driving safety

Engineering Contradiction:
Improvedriving safetyVSAvoiduser interaction convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical interaction method (touching screen buttons) with a voice-based acoustic system. Drivers can issue voice commands to control applications, eliminating the need to visually focus on and physically touch screen elements, thereby improving both driving safety and interaction convenience

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A "visible and speakable" implementation method and apparatus, and a vehicle. The method includes: receiving a voice instruction of a user, and obtaining semantic text information based on the voice instruction; obtaining a current display interface, and determining interface information of the display interface based on an information type of an application corresponding to the display interface; and outputting an execution instruction based on the interface information and the semantic text information, so as to perform an operation corresponding to the voice instruction. According to the method, the apparatus, and the vehicle, based on an information type of an application corresponding to a current display interface, interface information and an execution instruction of the display interface are obtained by using different solutions, thereby implementing diversification of an interface information obtaining manner and an instruction execution manner. A corresponding technical solution can be flexibly selected according to an actual situation, so that implementation and expansion of a "visible and speakable" service are more flexible, and are not limited to a single solution.
