Abstract: PROBLEM TO BE SOLVED: To suppress sudden change of operating points of an internal combustion engine which may occur when a travel mode is changed in the midst of operating the internal combustion engine.SOLUTION: When the travel mode is switched over in the midst of traveling by operating the engine, charging and discharging request power Pb* is set by slowly changing by the rate limit processing (S750-S800). The engine request power is set as the sum of charging and discharging request power Pb* and power for traveling, and the engine and two motors are controlled to travel by the power for traveling, while the engine is operated on an operating point obtained by operation line with the application of the engine request power. Since the engine request power is also slowly changed by slowly changing the charging and discharging request power Pb*, sudden change of the operating point of the engine can be suppressed.
