PROBLEM TO BE SOLVED: To suppress deterioration of travel performance in a reverse travel while an engine is load-driven.SOLUTION: In reverse travel while an engine is load-driven, upper limit torque Temax of the engine is set so that a sum of required torque Tr* and torque for cancelling torque exerted to driving in association with the load-driving of the engine can be output from a second motor to a drive shaft (S210). A product of the upper limit torque Temax of the engine and upper limit revolution speed Nemax thereof is set to upper limit power Pemax (S230), and target power Pe* of the engine is set within a range of the upper limit power Pemax (S260, S270, S300). Then, the engine and the first and second motors are controlled so as to output the target power Pe* from the engine and output the required torque Tr* to the drive shaft.SELECTED DRAWING: Figure 5 |
