PROBLEM TO BE SOLVED: To appropriately purge a vapor fuel gas even when an attempt is made to perform a driving operation for frequently changing an accelerator operation amount.SOLUTION: A hybrid vehicle 10 is configured to intermittently operate and stop an internal combustion engine 20 and control a torque generated by the engine and a torque generated by a second motor generator MG2. When a predetermined condition, including a condition that a coolant temperature THW of the internal combustion engine is higher than or equal to a permissible temperature, is satisfied, a fuel vapor gas purge system 100 is operated. When a specific driving operation state, including a state where the number of times of accelerator operation per unit time is higher than or equal to a threshold is detected, a permissible temperature is set to a lower value. In addition, when the specific driving operation state is detected, an update rate of a concentration learned value of the fuel vapor gas is increased and a rate of increase in a target purge rate is decreased. |
