摘要： A power supply apparatus of a vehicle includes: an engine and a first MG; a battery; a converter stepping up a voltage of the battery and supplying the stepped-up voltage to an inverter of the vehicle; and a control device controlling the converter in a continuous voltage step-up mode in which the converter is continuously operated and an intermittent voltage step-up mode in which the converter is intermittently operated. The control device estimates an SOC of the battery based on battery current IB flowing into and out of the battery, and forces the battery to be charged by the engine and the first MG when an estimate value of the SOC is lower than a predetermined lower limit. The control device suppresses an operation of the converter in the intermittent voltage step-up mode to a greater extent as the estimate value of the SOC is closer to the lower limit.

摘要： In a hybrid vehicle, noise occurrence caused in a rectangular wave control of a motor is restricted when a motor running mode is selected with a converter boosting limit applied. A motor controller for a hybrid vehicle mounted with an internal combustion engine and a motor as power sources is provided. The motor controller includes a converter capable of boosting a voltage supplied from a power supply device; an inverter which converts an output voltage of the converter to an AC voltage and applies the AC voltage to the motor; and a control unit which controls the inverter to drive the motor by switching between two or more control modes. When a running mode to drive the vehicle by a motor power alone is selected with a boost limit applied to the output voltage of the converter and when the motor is driven in a rectangular wave control mode or an overmodulation PWM control mode, the control unit raises the output voltage of the converter higher than a boost limit value and controls the inverter such that the control mode is switched to drive the motor in a sinusoidal PWM control mode.

摘要： A vehicle control apparatus includes a battery, a boost converter connected to the battery for boosting battery voltage, an inverter connected to the boost converter for performing DC to AC conversion, and a motor-generator connected to the inverter for outputting drive power. Then, if an inter-vehicle distance is less than or equal to a predetermined distance or a relative speed in approaching direction is greater than or equal to a predetermined speed, the output voltage of the boost converter is lowered. This suppresses the output of the motor-generator and controls the inter-vehicle distance.

摘要： An electrified vehicle includes a drive device including an alternating current motor and an inverter that drives the alternating current motor, a control device that controls the drive device, and a heat transfer device that transfers heat of the drive device to a heating target. When a predetermined heat requirement condition transferred to the heating target is satisfied, the control device executes loss increase control to control the drive device so that the power loss increases compared to a case where the heat requirement condition is not satisfied. When an index value regarding a rotation speed of the alternating current motor is less than a first threshold, the loss increase control includes first control to make a d-axis current of the alternating current motor larger than a reference d-axis current, which is the d-axis current when the heat requirement condition is not satisfied.
