A Methodology to Investigate the Dynamic Characteristics of ESP Hydraulic Units - Part II: Hardware-In-the-Loop Tests
Abstract
Abstract- The paper deals with the Hardware-In-the-Loop based methodology which was adopted to evaluate the dynamic characteristics of Electronic Stability Program (ESP) and Electro-Hydraulic Brake (EHB) system components. Firstly, it permits the identification of the time delays due to the hardware of the actuation system. Secondly, the link between the hardware of the hydraulic unit and a vehicle model running in real time permits the objective evaluation of the performance induced by the single components of different hydraulic units in terms of vehicle dynamics. The second part of this paper suggests the Hardware-In-the-Loop (HIL) tests which can be adopted to evaluate the influence exerted by the hydraulic hardware of the brake system on vehicle dynamics and handling.
