Hybrid vehicle and control method thereof
Abstract:
The invention provides a hybrid vehicle and a control method thereof with which, in a case where a vehicle speed V obtained by a vehicle speed sensor equals or exceeds a first determination vehicle speed V1 at a time of occurrence of an internal combustion engine-related abnormality, which is when an abnormality relating to motors MG1 and MG2 is determined not to have occurred but an abnormality relating to an engine is determined to have occurred while the engine is operative, the motors MG1 and MG2 are controlled such that traveling torque is output to a ring gear shaft serving as a drive shaft from the motor MG2 while the engine is motored by the motor MG1 such that a crankshaft rotates at a target rotation speed until the vehicle speed V subsequently falls to or below a second determination vehicle speed V2.
