In this paper, Hardware-in-the-Loop Simulation(HILS) is developed for evaluating a motor control unit on the signal level interface, simultaneously implementing a dynamic model of electric motor in real-time. Using Rapid control prototyping(RCP) device to function as MCU, motor controller generates PWM signals to HIL simulator, which runs dynamic models of inverter and electric motor, and receives the sensor signals calculated from those models in that simulator. In addition, the various fault signals from HIL simulator is inserted to RCP. It is expected that HILS can be used in developing and evaluating the control algorithm for MCU on the electric motor simulation.

In this paper, the BLDC(Brushless DC) motor control unit(MCU) is evaluated for failure mode by Hardware-in-the-Loop Simulation(HILS) on the signal level interface, simultaneously implementing a dynamic model of electric motor in real-time. The MCU generates PWM signals to HIL simulator, which runs dynamic models of inverter and electric motor, and receives the sensor signals calculated from those models in that simulator. We make the failure signal to the MCU IO interface by HIL simulator and evaluate performance of MCU in the failure mode. It is expected that HILS can be used in developing and evaluating the control algorithm for MCU on the electric motor failure mode simulation.

In the complex electric drive system, abnormal status which is considered at first stage of development are very diverse, difficult to predict and irregular. Therefore, the study of fail-safety technology is required prior to beginning any development. In many cases, failure mode test is not easy to represent in the lab. There are simple forms of failure mode like that wire short, open and complex forms like that abnormal signal of current sensor, position sensor, etc. Test of complex forms is time-consuming, expensive. And there is limitation number of test sample. Then we have to consider alternative method of real hardware test. HIL simulator can make the condition and environment for fault insertion. We will operate real time simulation with dynamic model in HIL simulator. It measures PWM duty ratio and frequency of MCU output signals for operating electric drive model. Even though virtual development environment system can simulate the MCU, in this paper, RCP will replace real hardware. Based on HIL simulator and RCP hardware, we can build virtual development environment for testing MCU performance with normal and failure mode. The research object of this paper is the electric drive system used in electric vehicle. This drive system is composed of PMSM, inverter, battery and controller. In this study, fault diagnosis logic of electric parts is investigated.

Because of environmental pollution and depletion of fossil fuels, hybrid and electric vehicles are being developed. Features of hybrid and electric vehicles is using electric motor as power source. Characteristic of these cars with high fuel efficiency and regenerative braking in order to implement it for research and study of electronic brakes are going to increase even more. In this paper, these regenerative braking and electronic brake for the development of MATLAB / Simulink and RT-Lab was built using the HILS environment. Electronic brake torque distribution logic to develop and apply, not only Regenerative braking, but also According to the distribution of braking, ride comfort quantitative assessment index " a measure of the study was about comfort.

The transition to eco-friendly mobility is accelerating around the world based on the recent national-level pollution-free vehicle conversion policy and raising environmental awareness. In order to achieve carbon neutrality in 2050, a rapid response is required, and attention is focused on the trend of mobility in Asia, which emits large amounts of greenhouse gas in the transportation sector. Therefore, if we take the lead in the development of two-wheeled and three-wheeled vehicles, which are the main means of transportation in many countries in East and Southwest Asia and are the main targets of vehicle electrification policies, it will be an opportunity to preoccupy major markets. In this study, performance tests were conducted with different battery systems mounted on the same electric three-wheeled vehicle, and the results were compared and analyzed to find ways to improve marketability.
