WARNING: This page is about a different car, the 2015 Hyundai Sonata. However, it is still accessible from the selected car via links, so may be relevant.
One CPU controls 2 motors (the traction motor and HSG motor). In addition to the basic function of motor control, the control board has supplementary features of protecting the motors, inverter and power module from overheating, preventing reverse rotation, detecting failure, and providing a motor temperature compensation circuit.
