Brake Pressure Control Electronics Vibration Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic brake pressure control systems in small motor vehicles like motorcycles and scooters face challenges in integrating a driving dynamics control device due to interference vibrations, which complicates installation and increases costs, as the dynamic control electronics require decoupling from engine vibrations, making it difficult to offer vehicles with or without this feature at a low cost.
Innovation Solution
Attaching the dynamic control electronics to the pressure medium unit's housing block, forming a preassembled unit that is anchored on the vehicle, effectively decoupling vibrations and simplifying the installation process, allowing for the same components to be used in vehicles with or without driving dynamics control, reducing assembly effort and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dynamic control electronics are integrated into the brake pressure control device, then the installation effort and costs are reduced, but the electronics are exposed to interference vibrations from the engine
Solution Approach 1:
A vibration-damping attachment element is introduced as an intermediary between the dynamic control electronics and the brake pressure control device. This mediator transmits necessary mechanical connections while filtering out harmful vibrations, allowing the electronics to be integrated into the brake pressure control device without direct exposure to engine vibrations.
Solution Approach 2:
The attachment element is designed to exploit the mass and structural properties of the brake pressure control device to its advantage. The device's inherent mass and mounting characteristics are used as a vibration filter, converting what would be a harmful vibration source into a beneficial damping mechanism that protects the sensitive electronics.
2Object-affected harmful factors
If the dynamic control electronics are placed at a distance from the pressure medium unit to avoid vibrations, then interference vibrations are reduced, but the assembly complexity and installation effort increase
Solution Approach 1:
The dynamic control electronics are merged with the brake pressure control device into a single integrated assembly. The vibration-damping attachment element enables this merging by providing a connection method that simultaneously achieves mechanical integration and vibration isolation, eliminating the need for separate mounting locations and reducing assembly complexity.
Solution Approach 2:
The brake pressure control device serves multiple functions: it houses the pressure medium control components, provides structural mounting, and acts as a vibration-damping platform for the dynamic control electronics. This multi-functionality reduces the overall system complexity and eliminates the need for additional vibration-isolation structures.
3Adaptability or versatility
If different control unit versions are produced for vehicles with and without driving dynamics control, then functional requirements are met, but production costs increase due to smaller production volumes
Solution Approach 1:
A single universal control unit design is created that can serve both vehicles with and without driving dynamics control. The dynamic control electronics are integrated into the brake pressure control device in a way that allows the same hardware platform to be used across different vehicle configurations, enabling economies of scale in production while maintaining functional adaptability through software or optional activation.
Solution Approach 2:
The control system is designed with dynamic configurability, allowing the same physical control unit to be activated or deactivated for driving dynamics control functions based on the vehicle configuration. This dynamic approach enables a single production line to serve multiple market segments without requiring separate control unit versions.

AI summary
The invention relates to an electronic brake pressure control system for vehicles. Brake pressure control systems of such vehicles comprise an anti-lock brake device and can optionally be extended with a vehicle movement dynamics control device. The latter comprises dynamics control electronics (20) which are, as is known, attached to the vehicle separately from the anti-lock brake device and connected to the brake pressure control unit (14) of the anti-lock brake device via a line connection. However, by means of their positioning on the vehicle, the dynamics control electronics (20) can be decoupled only in the case of vehicle-side interference vibrations. According to the invention, the dynamics control electronics (20) are attached to a pressure medium assembly (10) of the brake pressure control system and form, with the pressure medium assembly (10), a structural unit which can be pre-assembled and secured to the vehicle. In this, the dynamics control attracts (20) are effectively isolated from little-side interference vibrations, and brake pressure control systems with or without vehicle movement dynamics control can be made available commercially in parallel and in a cost effective way despite respective small individual production numbers. The expenditure on mounting on the vehicle is independent of the scope of equipment of the brake pressure control system.
