APPARATUS AND METHOD FOR CONTROLLING MOTOR FOR VEHICLE
A motor control apparatus for a vehicle includes a data detector detecting driving data and a vehicle controller controlling a drive motor according to the driving data. The vehicle controller includes an acceleration generator determining a request torque and a request speed using the driving data and generating a request acceleration using the request torque and the request speed; a driving point determinator selecting an inductance control current map or a motor efficiency control current map according to the request acceleration and determining a current driving point according to the request torque and the request speed using the selected current map; and a motor controller controlling the drive motor using the current driving point.
Power supply system
A power supply system includes a first controller that, controls an MG1 inverter, a second controller that controls an MG2 inverter, and a voltage sensor that detects a voltage generated from a pair of output terminals. The first controller controls the MG1 inverter according to a target value of the voltage generated from the output terminals, irrespective of the magnitude of a deviation between the target value of the voltage generated from the output terminals, and the detected voltage. The second controller controls the MG2 inverter according to the deviation. This processing is implemented by an effective value computing unit, effective value PI control unit, and a neutral point output voltage command unit.
