PROBLEM TO BE SOLVED: To optimize a warmup start time of an electric heating-type catalyst device.SOLUTION: A control device 200 of a hybrid system 100 switches an operation mode to a second operation mode when a battery charging amount is dropped to a prescribed mode switching charging amount or lower during a first operation mode, starts the power supply of a power amount necessary for raising a temperature of a catalyst to a prescribed temperature with respect to a heat generation body 151, warms up a catalyst device 15 before the operation mode is switched to the second mode, and learns a value of a warmup start charging amount so that the battery charging amount at the finish of the supply of the power amount to the heat generation body 151 approximates the mode switching charging amount on the basis of an operation history of the first operation mode, when a battery charging amount is dropped to the warmup start charging amount larger than a mode switching charging amount or lower during the first operation mode.SELECTED DRAWING: Figure 1 |
