PROBLEM TO BE SOLVED: To miniaturize a rotary electric machine and a battery.SOLUTION: A hybrid vehicle controller (100) for controlling a hybrid vehicle with an internal combustion engine (200), a first rotary electric machine (MG1), a differential mechanism (300), a second rotary electric machine (MG2) connected to a drive shaft (800) linking an axle, and a torque converter (400) interposed between the drive shaft and a power output shaft of the differential mechanism and having a lockup clutch (430). The hybrid vehicle controller includes a control means that controls the lockup clutch so that a torque capacity of the lockup clutch is an average value of a direct transmission torque transmitted from the internal combustion engine to the power output shaft when an engine speed in stopping the internal combustion engine belongs to a resonant frequency band of the internal combustion engine and so that the torque capacity is larger than the average value when the engine speed during stop control is less than a lower limit value of the resonant frequency band. |
