Solution Overview

Problem

The interaction between mobile and in-vehicle terminals is complex and inefficient, requiring users to split complex tasks into multiple commands, leading to poor user experience and potential distraction during driving.

Innovation Solution

The mobile terminal analyzes and automatically executes complex user commands by invoking necessary software and hardware of the in-vehicle terminal, reducing the need for direct user interaction and enhancing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the user splits complex tasks into multiple commands and sends them to the mobile terminal through the in-vehicle terminal, then the mobile terminal can execute the tasks, but the interaction operation becomes complex and interaction efficiency is low

Engineering Contradiction:
Improveinteraction efficiencyVSAvoidinteraction operation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mobile terminal automatically analyzes the user command and invokes necessary software and hardware of the in-vehicle terminal without requiring the user to manually split commands. The system serves itself by automatically determining what information needs to be obtained and executing the first function, thereby improving interaction efficiency while reducing operation complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mobile terminal acts as an intermediary between the user command and the in-vehicle terminal's hardware/software. It receives the user command, analyzes it, determines what information needs to be obtained, and automatically executes the function, thereby simplifying the interaction process and improving efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the mobile terminal directly executes user commands from the in-vehicle terminal, then the execution is simple, but complex tasks require multiple commands and user experience is poor

Engineering Contradiction:
Improveuser experienceVSAvoidtask execution efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The mobile terminal performs preliminary analysis of the user command to determine what information needs to be obtained before executing the first function. This preliminary action allows the system to automatically invoke the necessary software and hardware, improving both ease of operation and task execution efficiency without requiring multiple commands from the user.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the user interacts multiple times with the in-vehicle terminal to execute complex tasks, then the tasks can be completed, but distraction during driving increases and safety is compromised

Engineering Contradiction:
Improvedriving safetyVSAvoidinteraction operation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mobile terminal automatically analyzes and executes complex tasks without requiring multiple user interactions with the in-vehicle terminal. The system serves itself by automatically determining what information needs to be obtained and executing the functions, thereby reducing user distraction and improving driving safety while maintaining reliable task completion.

Inventive Principle:
Principle #25Self-service

AI summary

This disclosure relates to the field of terminals, and in particular, to a method for interaction between a mobile terminal and an in-vehicle terminal, a terminal, and a system. When a user command from an in-vehicle terminal is received, software and hardware of the in-vehicle terminal may be automatically invoked based on the user command to obtain information. This reduces a quantity of times of interaction between a user and the in-vehicle terminal and improves interaction efficiency. The method includes: A mobile terminal receives first information sent by an in-vehicle terminal, where the first information indicates to execute a first function. The mobile terminal determines a first indication based on the first information, and sends the first indication to the in-vehicle terminal, where the first indication indicates the in-vehicle terminal to obtain second information. The mobile terminal receives the second information sent by the in-vehicle terminal. The mobile terminal executes the first function based on the second information.
