Abstract: A control unit executes first current control for controlling a d-axis current component and a q-axis current component of a current to be supplied to a motor, second current control for controlling the d-axis current component and the q-axis current component based on a heating value target value related to a heating value generated in the motor and setting a ratio of the d-axis current component to the q-axis current component to be different from the ratio in the first current control, and vibration suppression control to be executed when the second current control is executed, and adds a first periodic signal to the torque target value in the vibration suppression control. A phase of the first periodic signal is shifted from a phase in a waveform of an output torque of the motor output when the second current control is executed without executing the vibration suppression control.

Abstract: A motor unit including: a first motor that drives a vehicle; a second motor that drives an auxiliary machine of the first motor; a first inverter that controls the first motor in response to a control signal transmitted from a main control device of the vehicle; and a second inverter that controls the second motor in response to a drive command signal for controlling the second motor transmitted from the first inverter, in which the second inverter transitions to an operation state of suppressing power consumption of the second inverter when reception of the drive command signal is finished.

Abstract: A drive device that rotates an axle of a vehicle includes a motor, a transmission that includes a decelerator connected to the motor, a housing that accommodates the motor and the transmission, a temperature sensor to detect a temperature of the motor, and a controller to control the motor. Oil supplied to the transmission is accommodated in the housing. The controller limits an output of the motor based on a detection result of the temperature sensor.
