PROBLEM TO BE SOLVED: To suppress deterioration of fuel economy when suppressing generation of rattling noise.SOLUTION: A control device 50 for a hybrid vehicle 100 includes a first change control part and a second change control part. The first change control part changes an operating point of an engine 2 to a low torque side when an absolute value of torque Tm of a motor generator MG2 lowers. The second change control part increases the torque Tm in a positive direction in accordance with the change of the operating point by the first change control part. A hysteresis to prevent hunting of the operating point and torque of a rotating machine caused by operations of the first and second change control parts includes: a first hysteresis to prevent hunting generated when the torque Tm is positive torque; and a second hysteresis to prevent hunting when the torque Tm is negative torque. The second hysteresis is smaller than the first hysteresis. |
