A vehicle drive device () is disclosed that includes a shift detent mechanism (); an actuator () that generates drive power for allowing the shift detent mechanism to operate; a sensor () that generates sensor information indicating an amount of operation of the shift detent mechanism; a control part () that controls the actuator; and a clutch () that is synchronized with operation of the shift detent mechanism, and when the control part changes a state of the clutch, the control part performs feedback control of the actuator based on a relationship between a target value for an amount of operation of the shift detent mechanism and the sensor information, and before completing the change in the state of the clutch, the feedback control ends and operation of the actuator stops.

Vehicle drive device and control device

A control device performs upshifting in a state in which an operating point of a rotating electrical machine for outputting requirement-based torque at wheel-based rotational speed falls within an operable range of the rotating electrical machine both before and after shifting a shift speed by the upshifting, and in which before shifting the shift speed, output torque from the rotating electrical machine is less than or equal to determination torque (T), the wheel-based rotational speed being rotational speed of the rotating electrical machine based on rotational speed (V) of a wheel, the requirement-based torque being output torque from the rotating electrical machine based on required wheel transmission torque, and the determination torque (T) being torque obtained by subtracting an amount of increased torque (&#x394;Tmg) resulting from torque increase control from maximum torque (Tmax) that can be outputted from the rotating electrical machine at the wheel-based rotational speed.

Control device

A rotary electric machine control device that performs drive control on an AC rotary electric machine using an inverter that converts power between DC power and AC power through pulse width modulation based on a carrier frequency, the rotary electric machine control device including: an electronic control unit that is configured to vary the carrier frequency such that the carrier frequency becomes higher as a rotational speed of the rotary electric machine becomes higher so that carrier sideband frequencies, which are frequencies of sideband waves that appear on higher and lower sides of a center frequency that is set in accordance with the carrier frequency, are not included in a frequency band prescribed in advance.

Rotary electric machine control device

A rotating electrical machine control device with an electronic control unit that is programmed to: switch a modulation method between asynchronous modulation in which switching of the inverter is controlled by modulated pulses generated based on a carrier having a first carrier frequency which is not synchronous with rotation of the rotating electrical machine and synchronous modulation in which switching of the inverter is controlled by modulated pulses generated in synchronization with rotation of the rotating electrical machine, the switching of the modulation method between the asynchronous modulation and the synchronous modulation being performed according to an operating condition of the rotating electrical machine which includes at least a rotational speed of the rotating electrical machine.
