    摘要： An inverter control apparatus for driving a polyphase AC motor for preventing abrupt changes in motor drive currents when switching of one phase is stopped. The apparatus includes a signal generator for generating duty signals of drive signals of respective phases on the basis of a generated reference waveform and a signal modifier for selecting one of the duty signals of one phase, holding it at a predetermined level, and modifying the duty signals of other phases according to the value required to hold the selected duty signal. On the basis of three-phase signal voltage levels, a decision is made on voltage fixing phase intervals by a phase decision circuit, and shift values are determined by an adder at every voltage fixing phase interval. Shift values are selected by a multiplexer according to the outputs of the phase decision circuit and added to triangular wave voltage. Resultant sum values are compared with the three-phase signal voltages to form a three-phase PWM signal.

    摘要： Three shafts of a planetary gear mechanism, which is a torque distribution mechanism, are connectable to an engine, a motor-generator and a compressor, respectively. An engine connecting shaft, a motor-generator connecting shaft and an accessory equipment connecting shaft are connected to a ring gear, a carrier and a sun gear, respectively. A single motor-generator can perform four different operations: a compressor driving operation when an idle stop function is performed, an engine starting operation by the motor-generator, a motor-generator driving operation by the engine, motor-generator driving and compressor driving operations by the engine.

    摘要： Planetary ratios of first and second planetary gear mechanisms are set such that all of the following values become equal to each other: a maximum value of a drive force of a first MG, which is generated when a total input-to-output speed ratio is a minimum value upon operation of the first MG as a motor; a maximum value of a drive force of the first MG, which is generated when the total input-to-output speed ratio is a maximum value upon operation of the first MG as the motor; and a maximum value of a drive force of the first MG, which is generated when the total input-to-output speed ratio is in a range from the minimum value to the maximum value upon operation of the first MG as a generator.
