Abstract
A hybrid vehicle includes an engine, a power storage device, a motor generator that receives electric power from the power storage device to generate travel driving force, and an ECU. The ECU selects one of a CD mode and a CS mode, and switches a traveling mode between EV traveling and HV traveling in accordance with a traveling condition in each of the CD mode and the CS mode. Responsiveness of a vehicle driving torque to an operation of an accelerator pedal is higher in the CD mode than in the CS mode.
Claims5
A hybrid vehicle comprising:
- an internal combustion engine;
- a power storage device;
- an electric motor configured to receive electric power from the power storage device to generate travel driving force;
- and
- a control device configured to select one of a CD (Charge Depleting) mode and a CS (Charge Sustaining) mode, and to switch a traveling mode between a first traveling mode and a second traveling mode in accordance with a traveling condition in each of the CD mode and the CS mode so as to cause the vehicle to travel, in the first traveling mode, the vehicle traveling by using the electric motor while stopping the internal combustion engine, and in the second traveling mode, the vehicle traveling while operating the internal combustion engine,
- wherein the control device is configured to select a responsiveness constant that is higher in the CD mode than in the CS mode, such that responsiveness of a vehicle driving torque to an operation of an accelerator pedal is higher in the CD mode than in the CS mode.
