Find Innovative SolutionsGenerate Solutions
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 executes complex user commands by automatically invoking software and hardware of the in-vehicle terminal, reducing the need for direct user interaction and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile terminal directly executes simple user commands from the in-vehicle terminal, then the execution speed is fast, but the interaction efficiency for complex tasks becomes low and user experience deteriorates
Solution Approach 1:
The complex user command is segmented into multiple sub-tasks, where the mobile terminal analyzes the command and divides it into information collection tasks (sent to in-vehicle terminal) and execution tasks (processed by mobile terminal). This segmentation allows each component to focus on specific operations, improving overall interaction efficiency for complex tasks while maintaining fast execution for simple commands.
Solution Approach 2:
The mobile terminal acts as an intermediary between the user command and the in-vehicle terminal hardware/software. It receives the user command, analyzes what information needs to be collected, sends collection indications to the in-vehicle terminal, receives the collected information, and then executes the function. This intermediary role enables efficient coordination for complex tasks without requiring direct user interaction with multiple components.
2Measurement precision
If the user splits complex tasks into multiple commands to execute them, then the task completion accuracy is high, but the interaction complexity increases and user experience becomes poor
Solution Approach 1:
The mobile terminal internally segments the complex user command into multiple sub-tasks (information collection and execution), but this segmentation is hidden from the user. The user only interacts with the mobile terminal once with the complex command, while the system handles the internal decomposition and coordination, thus maintaining high task completion accuracy without increasing interaction complexity.
Solution Approach 2:
The mobile terminal performs self-service by automatically analyzing the user command, determining what information needs to be collected, sending collection indications to the in-vehicle terminal, receiving the information, and executing the function without requiring the user to manually split or guide each step. This autonomous handling maintains high accuracy while simplifying user interaction.
3Productivity
If the mobile terminal automatically analyzes and executes complex user commands by invoking in-vehicle terminal software and hardware, then the interaction efficiency improves, but the system complexity increases
Solution Approach 1:
The mobile terminal serves as an intermediary that manages the complexity of coordinating between user commands and in-vehicle terminal hardware/software. It automatically analyzes commands, determines information collection needs, sends collection indications, receives information, and executes functions. This intermediary role consolidates system complexity in the mobile terminal while simplifying the interaction interface, improving efficiency without exposing the user to system complexity.
4Measurement precision
If the user directly interacts with the in-vehicle terminal for each command, then the control precision is high, but the time consumption increases and driving safety is compromised
Solution Approach 1:
The mobile terminal performs self-service by automatically analyzing user commands and initiating the information collection and execution process without requiring the user to manually interact with the in-vehicle terminal for each step. The user only needs to provide the initial complex command once, and the system handles the rest autonomously, significantly reducing time consumption while maintaining control precision through accurate command analysis and execution.

AI summary
A method for interaction between a mobile terminal and an in-vehicle terminal, a related terminal, and a related system are provided. 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. The method includes: a mobile terminal receives first information sent by an in-vehicle terminal, wherein 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, wherein 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.
