REGENERATION CONTROL DEVICE, HYBRID VEHICLE, REGENERATION CONTROL METHOD, AND COMPUTER PROGRAM
First Claim
1. A regeneration control device of a hybrid vehicle that includes an engine and an electric motor, that is capable of running by the engine or the electric motor or capable of running by a cooperation between the engine and the electric motor, and that is capable of performing regenerative power generation with the electric motor at least during deceleration, the regeneration control device comprising:
- detection means for detecting a performance of a brake of the hybrid vehicle;
wherein the regeneration control device performs;
a first regeneration control that is performed in a state in which an accelerator of the hybrid vehicle is in a closed state and a brake pedal is not depressed;
a second regeneration control that is performed in a state in which the accelerator of the hybrid vehicle is in the closed state and the brake pedal is depressed; and
a third regeneration control that is performed when the accelerator of the hybrid vehicle is in the closed state and a detection result from the detection means exceeds a predetermined value; and
wherein X<
Y<
Z is provided when an increase rate of regeneration torque in the first regeneration control is set at X(Nm/s), an increase rate of regeneration torque in the second regeneration control is set at Y(Nm/s), and an increase rate of regeneration torque in the third regeneration control is set at Z(Nm/s).

Abstract
A regeneration control device of a hybrid vehicle detects brake fluid pressure for detecting the amount of engagement of the brakes of a hybrid vehicle, and performs a first regeneration control in a closed state of the accelerator and the brake pedal not being depressed, a second regeneration control in the closed state of the accelerator and the brake pedal being depressed, and a third regeneration control when the accelerator pedal is in the closed state and the brake fluid pressure exceeds a predetermined value are executed, wherein X (Nm/s) is set as the rate of increase of regenerative torque in the first regeneration control, Y (Nm/s) is set as the rate of increase of regenerative torque in the second regeneration control, and Z (Nm/s) is set as the rate of increase of regenerative torque in the third regeneration control, then X<Y<X is satisfied.
