When an engaging element of a power transmission mechanism is half-engaged, excessive electric power is prevented from being input and output to a battery more appropriately. During a shift of the transmission (during a shift stage change), the torque capacity of the transmission is increased using the engine required power Pe *, the inertia power Piner of the hybrid unit, and the battery input / output limits Win and Wout. Lower limit values Tcmin and Tcmax are set (S130 to S160), and a shift is made using a torque capacity command Tc * of the transmission based on a value obtained by limiting the input shaft required torque Tin * with the upper and lower limit values Tcmin and Tcmax of the transmission torque capacity. The machine is controlled (S190, S200). [Selection] Figure 4 |
