During a hybrid drive, a hybrid vehicle sets an engine required power based on a driving required power and controls an engine to output the engine required power, while controlling a motor to drive the hybrid vehicle with the driving required power. When a catalyst temperature of an exhaust emission control device is equal to or lower than a predetermined temperature that requires warming up, in the state that an output upper limit power which a power storage device is allowed to output is equal to or larger than a predetermined power, the hybrid vehicle sets a power calculated by subtracting the output upper limit power from the driving required power, to the engine required power. In the state that the output upper limit power is smaller than the predetermined power, the hybrid vehicle sets the driving required power to the engine required power.

A hybrid vehicle includes a multi-cylinder engine, an exhaust gas control apparatus including a catalyst for removing exhaust gas from the multi-cylinder engine, an electric motor, and a control device configured to execute catalyst temperature increase control for stopping fuel supply to at least one cylinder and making an air-fuel ratio in each of remaining cylinders rich in a case where a temperature increase of a catalyst is requested during a load operation of the multi-cylinder engine, execute control such that an electric motor supplements insufficient drive power due to the execution of the catalyst temperature increase control, and change the air-fuel ratio in at least one of the remaining cylinders to a lean side after a temperature of the exhaust gas control apparatus becomes equal to or higher than a determination threshold value during the execution of the catalyst temperature increase control.

Methods and systems are provided for improving the operating range of an electric vehicle having an engine wherein waste heat generated during motor operation is transferred to pre-heat the engine. Engine starting is predicted based on the electrical torque demand of the vehicle relative to the actual and predicted electrical energy consumption of the electric vehicle. Prior to starting the engine to charge a battery of the motor, various engine components are pre-heated in an order that improves vehicle range while also optimizing fuel economy.

A power system is disclosed. The power system may include one or more memories and a controller. The controller may determine an exhaust temperature of an engine associated with a continuously variable transmission or a hybrid transmission. The controller may determine a target increase to the exhaust temperature based on the exhaust temperature failing to satisfy a threshold. The controller may determine, based on a lookup table, a target increase to a torque output of the engine based on the target increase to the exhaust temperature. The controller may cause a parasitic torque of the engine to be increased based on the target increase to the torque output.

A control device for a hybrid vehicle is provided. When a first drive mode is selected as the drive mode of the hybrid vehicle, a control section shifts the drive mode to a second drive mode when a charge amount of a battery for an electric motor becomes smaller than or equal to a determination charge amount. The first drive mode operates the electric motor while an internal combustion engine is stopped. The second drive mode permits the operation of the internal combustion engine. The control section executes a shifting process when the upper limit system output is lower than or equal to a startup determination output even though the charge amount of the battery is greater than the determination charge amount. The shifting process shifts the drive mode to the second drive mode to start the internal combustion engine.

A method of controlling a mode change in a hybrid vehicle for performing a driving-mode change related to a change in the amount of charge of a battery in consideration of catalyst warmup of an engine includes activating adaptive mode change control between a first mode and a second mode, determining whether or not catalyst heating or engine warmup is performed in advance, setting a mode change reference depending on a result of the determining, and performing the adaptive mode change control depending on the set mode change reference.
