System-Level Functional Safety Testing of MCU Based on Power-HIL

Abstract

“Electrification, interconnection, sharing and intellectualization†are the inevitable trend of the future development of the automobile industry. In recent years, most OEMS begin to attach importance to developing the EV/HEV/PHEVs. Being part of powertrain of the vehicle, the motor control unit is safety related electronic control units due to the severity of the accidents/incidents that could result if the MCU is not functional as intended. Therefore, functional safety (Fusa) related with E/E systems is becoming a key factor in the EV/HEV/PHEVs. According to the ISO26262 standard, this paper develops different test cases and test scenarios for system-level functional safety test & validation of MCU based on Power-level hardware-in-the-loop.
