Abstract
A engine starting method is carried out to start an engine of a vehicle. The vehicle includes a first hub, a second hub, and a damper. The damper connects the first hub and the second hub in a power transmission path between the engine and a generator capable of power generation and powered travel. The engine starting method determines whether or not the engine needs to be started, begins to crank the engine via the generator when the engine needs to be started, performs a first ignition when torque fluctuation caused by torsion in the first hub and the second hub is in a range of being absorbable by the damper during the cranking, and suppresses engine torque generated by the first ignition below engine torque generated by second and subsequent ignitions.
