Research and development tools for investigations of various facets of braking processes cover three major groups of devices:
- Dynamometer test rigs: assessment of performance, durability, life cycle and others;
- Tribometer test rigs: definition of parameters of friction and wear;
- Hardware-in-the-loop: estimation of functional properties of controlled braking.
A combination of the listed devices allows to research complex phenomena related to braking systems.
The presented work discusses a novel approach of test rig fusion, namely the combination of a brake dynamometer and hardware in the loop test rig. First investigations have been done during the operation of the anti-lock braking system (ABS) system to demonstrate the functionality of the approach. This task requires the following configuration of test equipment:
- NVH-brake dynamometer with integrated climatic chamber;
- Hardware-in-the-loop test rig including dSpace controllers, hydraulic brake system, and sensors and actuators of the ABS system;
Beside the introduction of the testing hardware, especially the dynamometer design layout and its operational parameters plus the hardware-in-the-loop test rig, the used control algorithms are presented. Moreover one can find the used parameters for first verification studies of the new approach.
As an essential conclusion it is recommended by the authors that future braking test equipment for the laboratory should consider the new and integrated approach of the Test Rig-in-the-Loop layout.
