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： A controller for a vehicle including two inverters determines whether a detector currently performs an insulation determination process, and if not, the controller performs random control to randomly vary carrier frequencies corresponding to the two inverters, respectively. In contrast, if the insulation determination process is currently performed, the controller prohibits the random control and fixes the carrier frequencies at reference frequencies, respectively. The reference frequencies are previously set to have a difference Δfs larger than a predetermined value f1.

摘要： When an electric vehicle outputs a torque instruction, firstly, a request torque is acquired and a judged whether the acquired request torque is positive or negative. Regardless of the sign of the request torque, it is judged whether the eco-switch is ON. If the request torque has a positive sign and the eco-switch is OFF, a map A is selected. If the eco-switch is ON, a map B which limits the maximum torque to a low value for the map A is selected. If the request torque has a negative sign, a map C is selected regardless of the eco-switch ON/OFF state and the maximum torque is not limited.

摘要： A loss reduction module of an electric vehicle control device has a function to limit a torque to not exceed a constant loss characteristic and issue a torque instruction if a requested torque exceeds the constant loss characteristic when an ecology switch is turned ON and low fuel consumption travel is instructed. More specifically, when a requested torque exceeding the constant loss characteristic is input, a torque limit is applied to a point on the constant loss characteristic. Accordingly, the torque instruction is output as a torque which is suppressed more than a characteristic curve obtained by combining the constant loss characteristic and a characteristic indicating the relationship between the torque and the number of rotations during normal travel.

摘要： In a drive system of an AC motor in which a motor current is feedback-controlled, a motor current command is produced in a normal operation according to a torque command value on an optimum efficiency characteristic line so as to select an optimum current phase maximizing an output torque with a constant motor current amplitude. Conversely, when the AC motor produces an excessively generated power exceeding a regeneratable power quantity of the AC motor, a consuming operation is performed for intentionally increasing the power loss in the AC motor. In the consuming operation, the motor current command is produced according to the torque command value on a loss increase characteristic line to change the current phase from the above optimum value. Thereby, the power loss in the AC motor can be increased to consume the surplus power without causing instability in the motor control.

摘要： In the hybrid vehicle, a boost converter is controlled to make a post-boost voltage or a voltage on the side of an inverter become a target post-boost voltage corresponding to a target operation point of a motor in accordance with a target post-boost voltage setting map that divides an operation region of the motor into a non-boost region and a boost region when a operation point of the motor is included in the boost region. The target post-boost voltage setting map is prepared so that the non-boost region includes a region in which a loss produced by driving the motor when not boosting the post-boost voltages becomes smaller than the loss produced when boosting the post-boost voltage and the boost region includes a region in which the loss produced when boosting the post-boost voltage becomes smaller than the loss produced when not boosting the post-boost voltage.
