Hydrostatic Traction Drive Parameterization via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of transferring driving behavior parameters from one type or model of mobile working machines to another, due to type/model-specific parameterization requirements in hydrostatic traction drives, make it difficult and costly to adapt driving behavior across different machines.
Innovation Solution
A hydrostatic traction drive with an electronic control device that stores a standardized characteristic diagram of setpoint driving behavior, allowing for the separation of working-machine-specific and driving-behavior-specific characteristics, enabling cost-effective parameterization and transfer across different types and models by using a speed-sensing device and operating interfaces to sense driving requests and map setpoint values.

1Manufacturing precision
If type-specific or model-specific parameterization is used for hydrostatic traction drives, then the driving behavior can be optimized for each specific machine type or model, but the cost and complexity of transferring driving behavior to other types or models increases significantly
Solution Approach 1:
The patent segments the parameterization process into two distinct parts: a standardized base parameter set that applies across all machine types, and type-specific or model-specific adjustment parameters. This segmentation allows the majority of driving behavior parameters to be transferred universally, while only requiring minimal adjustments for specific machine variants, thereby reducing overall parameterization complexity and cost.
Solution Approach 2:
The patent creates a universal parameterization framework where a single standardized characteristic diagram serves multiple machine types and models. This universal approach allows the same control device and parameter set to function across different hydrostatic traction drive configurations, eliminating the need for complete re-parameterization for each machine type while maintaining optimized driving behavior.
