Abstract:
1. A hybrid vehicle comprising: an engine, a rotating electric machine configured to control a revolution speed of the engine, and a control device configured to control ignition timing for startup of the engine, wherein the control device modifies the ignition timing for startup of the engine depending on whether or not the revolution speed of the engine is controlled by the rotating electric machine, the control device continues to set for a predetermined time, for startup of the engine, the ignition timing of the engine at a predetermined timing retarding amount, and then restores the ignition timing to a timing advancing direction at a predetermined restoring rate to the ignition timing of a steady operation of the engine, the control device modifies the predetermined time depending on whether or not the revolution speed of the engine is controlled by the rotating electric machine, and a case where the revolution speed of the engine is controlled by the rotating electric machine corresponds to a state where load is applied to the engine from the rotating electric machine, such that the revolution speed of the engine is maintained at a predetermined revolution speed by torque of the rotating electric machine, and a case where the revolution speed of the engine is not controlled by the rotating electric machine corresponds to a state where load is not applied to the engine from the rotating electric machine, and the revolution speed of the engine is not maintained at the predetermined revolution speed by torque of the rotating electric machine.
