Abstract: HILS (Hardware-In-the-Loop Simulation) is a scheme that incorporates hardware components of primary concern in the numerical simulation environment. Due to its advantages over actual vehicle test and pure simulation, HILS is being widely accepted in automotive industries as a test bench for designing, evaluating, and benchmarking vehicle control units. Developed in this study is a HILS system for the EHB (Electro-Hydraulic Brake) brake-by-wire system. The system includes a high pressure generator and a valve control system that independently modulates the brake pressures at four wheels. An EHB control logic and a VDC (Vehicle Dynamics Control) logic were tested in the HILS system. Test results under various driving conditions are presented in this paper.

Keywords: brake-by-wire; EHB; electro-hydraulic brakes; HILS; hardware-in-the-loop simulation; VDC; vehicle dynamics control; vehicle control; vehicle testing; brake pressures.
