Circuit/System Description

The drive motor position sensor is monitored by the motor control module. The motor control module monitors the angular position, speed and direction of the drive motor based upon the signals of the resolver-type position sensor. The position sensor allows the motor control module to determine the exact position, speed and direction of the drive motor. The hybrid/EV powertrain control module 1 also calculates motor speed and compares it to the motor control module's value to insure the accuracy of the hybrid/EV powertrain control module's value. This fault is handled inside the power inverter module, often referred to as the drive motor generator power inverter module and no external circuits are involved. The control modules listed below are part of the power inverter module and are not serviced separately:
