Abstract
A hybrid vehicle includes: a power generation device including an engine and an electric motor; an electrical storage device configured to exchange electric power with the electric motor; a shift device configured to allow a driver to perform a shift operation for deceleration; and an electronic control unit configured to control the power generation device such that an integral value of braking torque that is output from the power generation device during a period from when depression of an accelerator pedal is released and the shift operation is performed to when a predetermined time elapses in the case where a drive mode is a charge depleting mode is larger than the integral value in the case where the drive mode is a charge sustaining mode.
Claims8
A hybrid vehicle comprising:
- a power generation device including an engine and an electric motor;
- an electrical storage device configured to exchange electric power with the electric motor;
- a shift device configured to allow a driver to perform a shift operation for deceleration;
- and
- an electronic control unit configured to control the power generation device such that an integral value of braking torque when a drive mode of the hybrid vehicle is a charge depleting mode is larger than the integral value of the braking torque when the drive mode is a charge sustaining mode,
- the braking torque being a torque that is output from the power generation device during a period from when depression of an accelerator pedal is released and the shift operation is performed to when a predetermined time elapses.
A control method for a hybrid vehicle,
- the hybrid vehicle includes a power generation device, an electrical storage device, a shift device, and an electronic control unit,
- the power generation device including an engine and an electric motor,
- the electrical storage device being configured to exchange electric power with the electric motor,
- the shift device being configured to allow a driver to perform a shift operation for deceleration,
- the control method comprising:
- controlling, by the electronic control unit, the power generation device such that an integral value of braking torque when a drive mode of the hybrid vehicle is a charge depleting mode is larger than the integral value of the braking torque when the drive mode is a charge sustaining mode,
- the braking torque being a torque that is output from the power generation device during a period from when depression of an accelerator pedal is released and the shift operation is performed to when a predetermined time elapses.
