A purification catalyst is efficiently warmed up. When a warm-up request is made for a purification catalyst of an engine (S120), a rotational speed Ne1 and a torque Te1 that output a power of substantially zero based on a storage ratio SOC of a battery are set as a target rotational speed Ne * and a target. The execution time Tset1 of the first warm-up control for operating the engine is set as the torque Te *, and the warm-up engine power Pset and the warm-up engine power Pset are output based on the execution time Tset1 of the first warm-up control. The execution time Tset2 of the second warm-up control for operating the engine with the rotational speed Ne2 and the torque Te2 as the target rotational speed Ne * and the target torque Te * is set (S140, S150), and the first warm-up control is set to the first warm-up control. It is executed over the machine time Tset1 (S170 to S240), and then the second warm-up control is carried out over the second warm-up time Tset2. Rows (S250~S270, S200~S240). [Selection] Figure 3 |
