PROBLEM TO BE SOLVED: To make driving shaft torque closer to torque that a driver requires, and control the driving shaft torque so that no torque level difference is generated even if differential rotation speed of a planetary gear mechanism strides over a 0 point, so as to give a drive feeling with no strangeness.SOLUTION: In a control device 26 of a hybrid vehicle 1, an engine and a first motor generator 3 provided as power sources for a vehicle are connected to a driving shaft 15 through a planetary gear mechanism 5 so as to allow power to be transmitted to the shaft. Further the control device 26 of the hybrid vehicle 1 comprises torque control means which controls, on the basis of combined torque of the engine 2 and the first motor generator 3, output torque of a second motor generator 4 directly connected to the driving shaft 15, which also comprises calculating means that calculates loss torque ratios of the planetary gear mechanism 5. The torque control means corrects output torque of the second motor generator 4 according to the loss torque ratios of the planetary gear mechanism 5 calculated by the calculating means.SELECTED DRAWING: Figure 1 |
