    摘要： The present invention provides a motor controller capable of selecting a motor drive system that provides the best possible system efficiency, according to monitored parameters indicative of the vehicle condition and the conditions of the mounted components. A drive signal processing block of the motor controller outputs drive signals to the motor by using a first drive system and a second drive system causing less switching loss than the first drive system, depending on a demanded torque for the motor. A drive system determination block, when an operating point of the motor allows selection between the first drive system and the second drive system, performs switching from the first drive system to the second drive system, based on the condition of an electric component of the vehicle or the vehicle running condition.
