摘要：A control device of a vehicle drive device includes a fluid transmission devicehaving an input-side rotating element to which power from an engine is input and an
output-side rotating element outputting power to drive wheels, a first electric motordirectly or indirectly coupled to the input-side rotating element, and a second electricmotor directly or indirectly coupled to the drive wheels, the control device of a vehicledrive device having an electric path through which power is electrically transmitted bygiving/receiving electric power between the first electric motor and the second electricmotor and a mechanical path through which power is mechanically transmitted via thefluid transmission device, the control device of a vehicle drive device being configured tocontrol an operating point of the engine by adjusting a torque of the first electric motor,the torque of the first electric motor being adjusted such that a sum of an engine torqueand the torque of the first electric motor is balanced with an input-side load torquegenerated in the input-side rotating element depending on a speed ratio of the fluidtransmission device, the input-side load torque being obtained based on an enginerotation speed indicated by a target engine operating point, and the torque of the firstelectric motor being determined based on the input-side load torque and the enginetorque indicated by the target engine operating point, and the control device of a vehicledrive device adjusting a torque of the first electric motor while giving/receiving electricpower between the first electric motor and the second electric motor to reduce a speedratio of the fluid transmission device when a temperature of operating oil for actuatingthe fluid transmission device is lower as compared to when the temperature is higher.
