REGENERATION CONTROL DEVICE, HYBRID AUTOMOBILE, REGENERATION CONTROL METHOD, AND PROGRAM

The present invention secures an amount of regeneration without detracting from driver drivability. The present invention detects brake fluid pressure as a detection means detecting the amount of engagement of the brakes of a hybrid automobile. A first regeneration control executed in the state of the accelerator of the hybrid automobile being in a closed state and the brake pedal not being depressed, a second regeneration control executed in the state of the accelerator of the hybrid automobile being in a closed state and the brake pedal being depressed, and a third regeneration control executed when the accelerator pedal of the hybrid automobile is in the closed state and the brake fluid pressure exceeds a predetermined value are executed. The regeneration control device is configured in a manner such that when X (Nm/s) is the rate of increase of regenerative torque in the first regeneration control, Y (Nm/s) is the rate of increase of regenerative torque in the second regeneration control, and Z (Nm/s) is the rate of increase of regenerative torque in the third regeneration control, X < Y < X.
