Abstract: Pulsating current (ripple) is generated in a zero-phase current to increase a loss. A motor control system includes an inverter which drives a motor which includes windings separately wound around each phase and an inverter control unit which generates an output voltage pulse corresponding to each phase to control the inverter on the basis of a torque command value and a rotor position of the motor. The inverter control unit divides the output voltage pulse of at least one phase of the output voltage pulses into several pulses during one period of the output voltage pulse such that a zero-phase voltage of only one of positive and negative polarities is output several times from the motor in the one pulse period.

Abstract: A motor can be controlled in a user-friendly manner so that a phase current based on an input command torque command value is caused to flow to at least one among U-phase, V-phase, and W-phase windings of the motor, so that a predetermined in-phase current is superimposed on the phase current and caused to flow to at least one among the windings. The motor is controlled such that energization to one winding corresponding to a predetermined energization stop phase is stopped, for example, so that energization to the U-phase winding is stopped, and so that a V-phase current, a W-phase current and an in-phase current are caused to flow to each winding corresponding to a phase other than the energization stop phase, for example, so that the V-phase current, the W-phase current and the in-phase current are caused to flow to the V-phase winding and the W-phase winding.

Abstract: A vehicle air conditioner has a compressor, a radiator, a pressure reducer, a cooling heat exchanger, a temperature detector, and a prohibition request output part. The compressor draws and discharges a refrigerant. The radiator dissipates heat of the refrigerant. The pressure reducer decompresses and expands the refrigerant. The cooling heat exchanger cools an air blown into a vehicle compartment. The temperature detector detects a temperature of the cooling heat exchanger. The prohibition request output part outputs a request, which prohibits the idle stop control, to an idle stop controller when the engine is operated. The request prohibits the idle stop control until the temperature of the cooling heat exchanger falls to a temperature being enough cool to cool the air and a required cooling time elapses. The required cooling time is estimated to be required to make a passenger feel cool by the air.
