CONTROL DEVICE OF DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress reduction in power transmission efficiency of a driving device during traveling of a motor.SOLUTION: A hybrid vehicle includes: an engine; a first MG (motor generator); a second MG; a transmission; a differential device which has a carrier connected to the engine through the transmission, a sun gear connected to the first MG and a ring gear connected to the second MG and a driving wheel. In the hybrid vehicle, a control device selects an engine stop mode B for controlling the first MG so that the first MG is made into a rotation state while maintaining the engine in a stop state and making the transmission into a neutral state when an ATF (Automatic Transmission Fluid)temperature (the temperature of oil in a driving device including the transmission and the differential device) is less than a low temperature threshold value Tlow during traveling of a motor which stops the engine and travels using the second MG.SELECTED DRAWING: Figure 7
