Regeneration control device, hybrid vehicle, regeneration control method, and computer program

摘要

The present invention improves fuel efficiency of an engine that is the power source of an auxiliary machine. Configured is a regeneration control device that has a control means that, when a hybrid automobile is stopped, the accelerator is in a closed state, and the auxiliary machine is in an operating state, and when the indicated value for the amount of fuel injection of the engine is equal to or more than a predetermined threshold, or the indicated value exceed the threshold, causes a driving mode wherein the engine and an electric motor cooperate during deceleration after the hybrid automobile has started moving.

主权项

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, that is capable of performing regenerative power generation with the electric motor at least during deceleration, and that is equipped with an auxiliary machine that uses the engine as a power source, the regeneration control device comprising:
a hybrid electronic control unit for controlling the operation of the engine and electric motor and configured to perform functions of a contra unit and a controller,
the control unit for deciding whether an instructed value of an amount of fuel injection of the engine is equal to or more than a predetermined threshold while the hybrid vehicle is stationary, an accelerator is in a closed state, and the auxiliary machine is in operation; andthe controller for controlling the operation of the engine and the motor to cause the hybrid vehicle to run by the cooperation between the engine and the electric motor during deceleration after the instructed value has been decided as being equal to or more than the predetermined threshold and then the hybrid vehicle has started.
