A drive unit for a vehicle may include a motor, a casing accommodating the motor, an electric pump unit attached to a lower part of the casing and configured to circulate heat medium within the casing and a filter unit attached to the lower part of the casing and configured to filter the heat medium. At least a part of the electric pump unit and at least a part of the filter unit each protrude outside the casing. Outside the casing, the filter unit is adjacent to the electric pump unit from a front in the vehicle.

Drive unit for vehicle and vehicle comprising the same

A control device includes an information acquisition unit configured to acquire information related to an air density in a coil and information related to a voltage applied to a rotary electric machine, an insulation determination unit configured to determine whether or not dielectric breakdown occurs in the coil based on the information related to the air density and the information related to the voltage acquired by the information acquisition unit, and configured to determine whether or not an insulation state of the coil is needed to be maintained by supplying an oil to the coil, and a drive instruction unit configured to drive an oil supply unit, when the insulation determination unit determines that dielectric breakdown occurs in the coil and determines that the insulation state of the coil is needed to be maintained by supplying the oil to the coil.

Control device for rotary electric machine unit

A control apparatus includes: a rotor temperature estimation unit estimating a temperature of a rotor based on stator temperature information from a first temperature sensor for identifying a temperature of a stator, refrigerant temperature information from a second temperature sensor for identifying a temperature of refrigerant used to cool an electric motor, and rotation speed information about the rotor from a resolver for identifying a rotation speed of the rotor; and an electric motor control unit controlling at least one of an output characteristic and a drive condition of the electric motor based on the temperature of the rotor estimated by the rotor temperature estimation unit.
