摘要： A control device includes a PWM control unit that executes PWM control over an alternating-current motor mounted on a vehicle. The PWM control unit includes an alarm sound generation processing unit and a slip determination unit. The slip determination unit determines whether a drive wheel coupled to the alternating-current motor is slipping on the basis. of a d-axis current (Id), a q-axis current (Iq), a d-axis voltage command value (Vd) and a q-axis voltage command value (Vq) of the alternating-current motor. When the drive wheel is not slipping, the alarm sound generation processing unit generates an alarm sound from the alternating-current motor by adding a variation value (ΔV) to the d-axis voltage command value (Vd) at a predetermined interval. When the drive wheel is slipping, the alarm sound generation processing unit temporarily stops adding the variation value (ΔV) to the d-axis voltage command value (Vd).

摘要： A control device includes a PWM control unit that executes PWM control over an alternating-current motor mounted on a vehicle. The PWM control unit includes an alarm sound generation processing unit that executes an alarm sound generating process of generating an alarm sound from the motor for informing a pedestrian, or the like, of the approach of the vehicle by intentionally varying phase current flowing through the motor by periodically adding a variation value (ΔV) to a d-axis voltage command value (Vd) at a predetermined interval. At the time of executing the alarm sound generating process, the alarm sound generation processing unit adjusts the variation value (ΔV) such that the d-axis voltage command value (Vda) resulting from the alarm sound generating process (the sum of Vd and ΔV) falls within a range in which it is possible to suppress occurrence of an overcurrent in the motor.

摘要： A control device controls an inverter controlling an output of a motor by PWM control. The control device calculates a reference frequency based on a torque and a rotation speed of the motor, calculates a random coefficient using two data tables, and calculates, as a random frequency, a value obtained by adding, to a reference frequency, a value obtained by multiplying a prescribed width by the random coefficient. The control device calculates control limit lines based on the rotation speed of the motor, and corrects the random frequency so as to fall within a range that is higher than the control limit line and lower than the control limit line. The control device generates a carrier signal having a random frequency as a carrier frequency.

摘要： When request power required of a power supply device by a driving force generation unit is close to zero, a converter ECU controls first and second converters to prohibit respective amounts of current passage in the first and second converters from simultaneously becoming close to zero. That is, when the request power is close to zero, the converter ECU performs voltage control of the first converter and sets an electric power control value for the second converter subjected to current control (electric power control) to a nonzero value, such that electric power is supplied and received between the first and second converters.

摘要： A control device divides 360° corresponding to one cycle of a resolver angle into N zones, and determines whether or not a resolver angle θ in the current cycle exceeds a division border. When determined that resolver angle θ in the current cycle exceeds a division border, the control device calculates a time difference ΔT[n] between a calculation time T[n] in the immediately preceding resolver cycle and a calculation time T in the current cycle. The control device also calculates a resolver angle variation Δθ[n] with time difference ΔT[n] by adding 360° to the difference between resolver angle θ obtained in the current cycle and a resolver angle θ[n] obtained in the immediately preceding resolver cycle. The control device then calculates a rotation speed NM by multiplying, by a coefficient K, a value obtained by dividing Δθ[n] by ΔT[n].
