| Control function |
Torque control |
Generates torque by controlling the amount and direction of stator current according to the position of rotor. |
- Controls current
- Detects rotor position and speed
|
| Protection function |
Over temperature limit |
Restricts the motor power if restrictive temperature of inverter and motor exceeds the limit. |
Restricts the max. motor power according to inverter and motor temperature. |
| Failure detection |
- Detects external interface related problems
- Detects faults in the inverter
|
- Detects faults associated with inverter
- Detects performance related faults
- Detects inverter hardware failure
|
| Cooperative control |
Vehicle driving control |
Communicates with other controllers of necessary information to the vehicle |
- Receives data for demanded torque, battery condition, EWP, etc.
- Transmits inverter status information
