Fault Injection Test for MCU Based On E-Motor Emulator*

With the rapid development of electric vehicles, there are more and more electronic devices in one vehicle. Meanwhile, with the trend of increasing technological complexity, software content, there are increasing risks from systematic failures and random hardware failures. The e-motor Drive System (e-motor and MCU), as the core powertrain system of the EV/HEVs, are safety related electronic control units (ECU) due to the severity of the accidents/incidents. Accordingly, the ISO 26262 standard has provided suggestions for the functional safety design and testing of automotive electronic devices. Therefore, the functional safety of MCU needs to be confirmed, tested and evaluated. The hardware-in-the-loop (HIL) system based on power level is an efficient and safe testing system. The objective of this paper is to introduce fault injection test for MCU based on e-motor emulator at power level
