This paper presents a design procedure of the virtual test environment for fail-safe algorithm development of a motor control unit (MCU) in the electric or hybrid-electric vehicle, using a hardware-in-the-loop (HIL) simulator. Mathematical models of the vehicle, the battery, the permanent magnet synchronous motor (PMSM), and the inverter are developed based on the physical and engineering principles and programmed to be executed in real-time. The programmed models emulate the performance of each component and run in the HIL simulator. The signal interface between the HIL simulator and a MCU is also developed by designing appropriate wire harness and signal matching. Fault diagnosis of a MCU is conducted to show the feasibility of the virtual test environment. Several different failure modes of the MCU are implemented and tested by the HIL simulator to show the possibility of fault detection and fault diagnosis algorithms of the MCU in real-time.
