Abstract
Official abstract text for this publication.
A hybrid vehicle comprises an engine configured to output power for driving and equipped with an exhaust emission control device in an exhaust system thereof. The hybrid vehicle further comprises a control device. In response to a predetermined rotation request for rotating the engine with no need to output power from the engine, the control device performs a control to rotate the engine with fuel injection when a catalyst temperature in the exhaust emission control device is equal to or higher than a predetermined temperature, while performing a control to rotate the engine without the fuel injection when the catalyst temperature is lower than the predetermined temperature.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hybrid vehicle, comprising: an engine configured to output power for driving and equipped with an exhaust emission control device in an exhaust system thereof; a first motor configured to motor the engine; a second motor configured to output power for driving; a power storage device configured to transmit electric power to and from the first motor and the second motor; and a control device configured to control the engine, the first motor and the second motor, wherein in response to a predetermined rotation request for rotating the engine with no need to output power from the engine, when a catalyst temperature in the exhaust emission control device is equal to or higher than a predetermined temperature, the control device performs a first control that controls the engine and the first motor to rotate the engine with fuel injection, and when the catalyst temperature is lower than the predetermined temperature, the control device performs a second control that controls the engine and the first motor to rotate the engine without the fuel injection. 2. The hybrid vehicle according to claim 1 , wherein the predetermined rotation request comprises a request for rotating the engine to apply engine braking. 3. The hybrid vehicle according to claim 1 , wherein the predetermined rotation request comprises a request for rotating the engine to drive a mechanical pump that is driven by rotation of an output shaft of the engine. 4. The hybrid vehicle according to claim 1 , wherein the control device causes the engine to be motored using a larger torque in the second control, compared with a torque used in the first control. 5. The hybrid vehicle according to claim 1 , wherein the catalyst temperature is either a detected value from a temperature sensor mounted to the exhaust emission control device or an estimated value that is estimated from a cooling water temperature of the engine.
