摘要 PROBLEM TO BE SOLVED: To keep a driver from feeling discomfort due to strange exhaust noise of an engine at the time of charging a battery while an engine is being run with a vehicle at a halt.SOLUTION: When a request power Pe* ranges from a threshold Pref1 to a threshold Pref (S120) and a vehicle is at a halt, if the halt is predicted to last over a predetermined time or longer (S130 and S140), a running point is set to a point where the number of rotations is larger than that on a booming sound suppressing operation line and a torque is lower than that on the booming sound suppressing operation line. When the request power Pe* ranges from the threshold Pref1 to a threshold Pref3, the running point is set to a point where a torque change rate is smaller than that on the booming sound suppressing operation line. When the request power Pe* ranges from the threshold Pref3 to the threshold Pref2, the running point is set to a point where the number of rotations Ne is held constant and a torque Te gets larger when the request power Pe* is larger. An engine is run at such the running point dependent on a strange exhaust noise suppressing operation line and the request power Pe* (S160 and S170).
