Integrated Brake Control Module for Axle Pressure Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic braking systems for commercial vehicles require complex wiring and additional electronics for side-specific ABS control, leading to increased complexity and potential failures due to the need for multiple pressure control channels and communication between brake control valves.
Innovation Solution
A compact brake control module with three integrated brake control valves, a processor unit, and two separate compressed air supply ports, allowing for independent control of front and rear axles with reduced wiring and redundancy to maintain pressure in case of circuit failure, utilizing relay valves and sensors for precise pressure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate pressure control modules are provided for front axle and rear axle with multiple ABS pressure control modules per wheel, then side-specific ABS control capability is improved, but wiring complexity and device complexity increase significantly
Solution Approach 1:
The patent combines multiple pressure control valves (first brake control valve for front axle, second and third brake control valves for rear axle) into a single integrated brake control module. This merging eliminates the need for separate modules and extensive wiring between them, while maintaining the capability for independent control of each axle and wheel through the integrated valve design and centralized processor unit.
Solution Approach 2:
The integrated brake control module performs multiple functions: it controls front axle brakes through the first brake control valve, controls rear axle brakes through the second and third brake control valves, and provides ABS control for individual wheels. The single processor unit coordinates all these functions, making the module universal and eliminating the need for separate dedicated modules for each function.
2Reliability
If multiple separate pressure control channels are implemented for front and rear axles, then braking stability and reliability are improved, but the number of components and system complexity increase
Solution Approach 1:
The patent merges multiple pressure control channels into a single integrated module while maintaining their functional independence. The first brake control valve controls front axle pressure, while the second and third brake control valves control rear axle pressure, all within one module. This reduces the number of separate physical modules while preserving the reliability benefits of multiple control channels.
Solution Approach 2:
Within the integrated module, the patent segments the control functions into separate brake control valves (first for front axle, second and third for rear axle) with dedicated compressed air supply ports. This segmentation maintains functional independence and braking stability while consolidating the physical structure into one module.
3Reliability
If dedicated compressed air supply ports are provided for each brake control valve, then system reliability and redundancy are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple compressed air supply ports (first compressed air supply port for front axle, second compressed air supply port for rear axle) into a single integrated brake control module. This merging maintains the redundancy and reliability benefits of separate air supplies while reducing the overall system complexity by consolidating the structure.

AI summary
A brake control module includes: a first brake-control-valve (BCV), the output of which is connected to at least one controlled port; a second BCV, the output of which is connected to a third controlled port; a third BCV, the output of which is connected to a fourth controlled port; a processor unit, which is adapted to control and/or influence brake pressures; at least one control port, which is adapted to activate at least one of the BCVs; in which the first BCV is connected to a first compressed air supply port, and the second BCV and the third BCV are connected to a second compressed air supply port. The brake control module allows the front and rear axle brake cylinders to be activated. Only one processor unit is required, which is in the central brake control module, and much of the wiring is eliminated.
