Solution Overview

Problem

Existing brake systems for vehicles require numerous wires and mounting space, and a failure in electronically controlled brake systems can lead to serious accidents.

Innovation Solution

An integrated electronic brake system with a main control section and a sub-control section connected via an internal connection bus, allowing the sub-control section to take over in case of failure, reducing size and weight while maintaining stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single control module is used for brake control, then the device complexity is reduced, but the reliability decreases due to potential failure points

Engineering Contradiction:

Improvebrake system reliabilityVSAvoidcontrol module structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control module is divided into a main control section and a sub-control section. The main control section handles normal brake operations, while the sub-control section serves as a backup that can take over in case of main control failure. This segmentation allows the system to maintain high reliability through redundancy while managing complexity through functional division.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sub-control section is prepared in advance as a backup control unit with the capability to perform brake control functions. This beforehand cushioning ensures that if the main control section fails, the system can immediately switch to the sub-control section without loss of brake functionality, thus maintaining reliability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If multiple separate brake control systems are installed for redundancy, then the reliability is improved, but the mounting space and weight increase

Engineering Contradiction:

Improvebrake system reliabilityVSAvoidmounting space

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The main control section and sub-control section are integrated into a single control module housing rather than being separate physical systems. This merging approach provides the reliability benefits of having redundant control capabilities while minimizing the mounting space required, as both control sections share the same physical space and infrastructure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sub-control section is designed with multi-functionality, capable of performing the same brake control functions as the main control section. This universality allows a single compact module to house redundant control capabilities without requiring separate dedicated spaces for each control system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If multiple separate brake control systems are installed for redundancy, then the reliability is improved, but the weight increases

Engineering Contradiction:

Improvebrake system reliabilityVSAvoidcontrol system weight

Core Design Contradiction:

ReliabilityVSWeight of stationary object

Solution Approach 1:

The control module consolidates both the main control section and sub-control section into a single integrated unit. This merging eliminates the need for separate housings, wiring harnesses, and mounting structures that would otherwise be required for two independent control systems, thereby reducing the overall weight while maintaining redundant control functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sub-control section is designed to be universal in its capabilities, able to perform all necessary brake control functions independently. This multi-functionality allows the system to achieve reliability through redundancy without requiring additional specialized components that would increase weight.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Area of stationary object

If a single control module is used, then the mounting space is reduced, but the reliability decreases due to potential failure

Engineering Contradiction:

Improvemounting spaceVSAvoidbrake system reliability

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The control module is segmented into distinct main and sub-control sections with separate processing capabilities. This segmentation within a single housing allows the system to occupy minimal mounting space while maintaining the reliability benefits of redundant control paths that can take over upon failure.

Inventive Principle:

Principle #1Segmentation

AI summary

An integrated electronic brake system includes a main control section configured in a first area to receive one or more of a value from a pedal sensor, a value from a cylinder pressure sensor, a value from a wheel speed sensor, or an EPB signal to perform EPB control and drive a main braking valve and a braking motor for the main braking of a vehicle, and to drive an additional braking valve for the additional braking, a sub-control section configured in a second area to receive one or more of the value from the pedal sensor, the value from the wheel speed sensor, or the EPB signal to perform the EPB control and drive the main braking valve and the braking motor through a bypass circuit, and a connection bus connecting the first and second areas mounted in one box to transfer signals between the main and sub-control sections.
