Abstract
Electric power steering (EPS) is increasing its number and expanding to heavier vehicles. We developed new motor control unit (MCU) for EPS. Motor and ECU were integrated for better installation and adopted redundant 2-drive design for more safe EPS. Developed MCU maintains assist of EPS even after failure in one drive unit. We also upgraded its performance with 2-drive technologies.
