| 20090259391 | Hybrid vehicle and control method of hybrid vehicle - When a start command of an engine is given in the presence of the driver's power demand, the start control sets the ignition timing of the engine to a power demand ignition timing, in order to enable quick output of a large power from the engine in response to the driver's power demand. When the start command of the engine is given in the absence of the driver's power demand in a vehicle drive state, there is little possibility of the occurrence of gear chattering noise because of application of a torque to a driveshaft. The start control accordingly sets the ignition timing of the engine to a vibration control ignition timing, in order to reduce the vibration of the vehicle body. When the start command of the engine is given in the absence of the driver's power demand in a vehicle stop state, on the other hand, application of a small torque may cause the occurrence of chattering noise. The start control accordingly sets the ignition timing of the engine to a chattering control ignition timing, in order to generate a certain level of torque that prevents repeated contact and separation of gears in a gear mechanism even in the event of an engine-induced torque variation. | 10-15-2009 |
