HILS test method is generally useful for the ESC system validation. Recently trends in development of the ESC system are the rapid development of the software such as VAFs(Value Added Functions), and the integrated chassis control system development. The dry type HILS is the effective method to validate ESC system without the HCU hardware during quickly proceeding with the development process, and the interaction of the integrated chassis system without the each actuator hardware. In this paper the dry type HILS for the ESC system is proposed with the direct measurement approach of ECU coil’s current and the motor BEMF voltage control simulator. The paper investigates the dry type HILS system design based on the important technology, and the designed dry type HILS is verified though the simulation using real ECU. Also, in order to verify the coil’s current measurement reliability, the measurement result is compared to oscilloscope data.

Fault detection and diagnosis method become increasingly important for the robust electronic mechanical system. Especially, in the automotive industry field, the quality problem can delay the implementation of the new technology in the market. In this paper, the sensor fault diagnosis method is proposed with parity space approach for EMB (Electro-Mechanical Brake) system. The paper investigates the EMB system modeling including sensors, and the model based fault detection algorithm is verified through the closed loop simulation using Matlab-Simulink, Also, in order to verify the modeling error under the normal condition, the simulation result is compared to HILS bench test result.
