Solution Overview

Problem

Communication between an automobile diagnostic instrument and electronic control units (ECUs) in a vehicle is time-consuming due to serial interaction, leading to low diagnosis efficiency.

Innovation Solution

A method involving grouping ECUs with similar communication parameters into one group and creating parallel communication links to facilitate simultaneous interaction, allowing parallel communication command transmission without interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If serial communication mode is used between automobile diagnostic instrument and ECUs, then communication simplicity is maintained, but communication time increases and diagnosis efficiency decreases

Engineering Contradiction:
Improvediagnosis efficiencyVSAvoidcommunication interaction time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent segments ECUs into multiple groups based on their communication parameters (such as communication protocols, baud rates, and data formats). Each group is assigned a dedicated communication link, allowing simultaneous parallel communication with multiple ECUs. This segmentation transforms the traditional serial one-by-one communication approach into parallel group-based communication, significantly reducing total communication time and improving diagnosis efficiency.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple ECUs are communicated with simultaneously using parallel communication, then communication efficiency improves, but communication system complexity increases

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidcommunication link configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a universal communication link configuration that can adapt to different ECU types and communication parameters. By establishing communication links with standardized interfaces and protocols that can handle multiple ECU groups, the system achieves parallel communication capability without proportionally increasing complexity. The communication links are designed to be multi-functional, supporting different communication standards and parameter sets through a unified framework.

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

Solution Approach 2:

The patent performs preliminary classification and grouping of ECUs based on their communication parameters before establishing communication links. This preliminary action organizes ECUs into manageable groups, simplifying the subsequent parallel communication process. By pre-configuring the communication architecture and grouping ECUs in advance, the system reduces the complexity of real-time communication management while maintaining high efficiency.

Inventive Principle:
Principle #10Preliminary action
