Abstract
A control apparatus for a hybrid vehicle that includes a battery includes a controller that controls a charge amount of the battery. The controller limits the charge amount of the battery at a time of low vehicle speed even when a state of charge of the battery has fallen. The controller relaxes a limitation on the charge amount when a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is selected as a driving mode of the hybrid vehicle.
Claims14
A control apparatus for a hybrid vehicle that includes a battery, comprising:
- a controller that controls a charge amount of the battery,
- wherein the controller limits the charge amount of the battery at a time of low vehicle speed even when a state of charge of the battery has fallen, and
- wherein the controller relaxes a limitation on the charge amount when a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is selected as a driving mode of the hybrid vehicle.
A control apparatus for a hybrid vehicle that includes a battery, comprising:
- a controller that controls a charge amount of the battery,
- wherein the controller limits the charge amount of the battery at a time of a fall in a state of charge when a vehicle speed is low, on a condition that a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is not selected as a driving mode of the hybrid vehicle.
A control apparatus for a hybrid vehicle that includes an engine, comprising:
- a controller that controls operation of the engine in accordance with a driving state of the hybrid vehicle,
- wherein the controller limits the operation of the engine to generate an electric power when a vehicle speed is low, and
- wherein the controller relaxes a limitation on the operation of the engine when a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is selected as a driving mode of the hybrid vehicle.
A control apparatus for a hybrid vehicle that includes an engine, comprising:
- a controller that controls operation of the engine in accordance with a driving state of the hybrid vehicle,
- wherein the controller limits the operation of the engine for electric power generation when a vehicle speed is low, on a condition that a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is not selected as a driving mode of the hybrid vehicle.
A control apparatus for a hybrid vehicle that includes a battery, comprising:
- a controller that controls a charge amount of the battery during a power driving mode, in which higher priority is given to responsiveness of a driving force than a normal driving mode;
- wherein the controller is operable for limiting the charge amount of the battery even when a state of charge of the battery has fallen, and
- wherein the controller is operable for relaxing a limitation on the charge amount when the power driving mode is selected as a driving mode of the hybrid vehicle.
A method of controlling a hybrid vehicle that includes a battery, and a controller that controls a charge amount of the battery during a power driving mode in which higher priority is given to responsiveness of a driving force than a normal driving mode;
- the method comprising:
- limiting the charge amount of the battery even when a state of charge of the battery has fallen, and
- relaxing a limitation on the charge amount when the power driving mode is selected as a driving mode of the hybrid vehicle.
A method of controlling a hybrid vehicle that includes a battery, and a controller that controls a charge amount of the battery during a power driving mode, in which higher priority is given to responsiveness of a driving force than a normal driving mode;
- the method comprising:
- limiting the charge amount of the battery even when a state of charge of the battery has fallen;
- and
- lifting a limitation on the charge amount when the power driving mode is selected as a driving mode of the hybrid vehicle.
