摘要： A converter controls a system voltage, which is a DC link voltage of an inverter, in accordance with a voltage command value. The inverter outputs a rectangular wave voltage having the system voltage as amplitude to an AC motor during application of rectangular wave voltage control. During application of rectangular wave voltage control, a voltage command value for the system voltage is modified such that a current phase on a d-q plane of the AC motor is brought closer to a target current phase line. The target current phase line is set on an advance side relative to an optimal current phase line which is a set of current phases at which output torque is maximized for the same amplitude of a motor current in the AC motor.

摘要： In hybrid electric vehicle control, when an engine is cranked by the torque of a first motor-generator to start the engine, the torque of the first motor-generator is corrected according to the crankshaft angle of the engine to prevent the amount of increase in engine rotation speed from fluctuating. Fluctuation in inertia torque is reduced through this control of the torque of the first motor-generator to reduce fluctuation in the cranking reaction force torque exerted on a drive axle. Further, the torque of a second motor-generator is so controlled to cancel out this cranking reaction force torque. Thus, the cranking reaction force torque exerted on the drive axle is accurately canceled out through control of the torque of the second motor-generator to suppress fluctuation in the torque of the drive axle.

摘要： In an electric motor drive system for an electric vehicle that includes a converter for performing direct-current voltage conversion and an inverter that converts the output voltage of the converter into alternating-current voltage, a control apparatus makes a required torque response determination to determine whether the electric vehicle is in a state in which high torque response is needed. Furthermore, in a drivability priority mode in which high torque response is needed, the control apparatus sets a voltage command value for the converter in a range where sine wave PWM control can be applied. On the other hand, in a fuel efficiency priority mode in which high torque response is not needed, the control apparatus sets the voltage command value for the converter such that power loss in the overall electric motor drive system is minimized, based on the operating state of an alternating-current electric motor.
