Hybrid vehicle and control method for hybrid vehicle
Abstract:
A hybrid vehicle intermittently operates and stops an engine, travels through control over torque generated by the engine and torque generated by a second motor generator, causes a fuel vapor gas purge system to carry out purging of fuel vapor gas when a predetermined condition, including a condition that a coolant temperature is higher than or equal to a permissible temperature, is satisfied, and sets the permissible temperature to a value lower when a specific driving operation state that includes a state where the number of times of accelerator operation per unit time is higher than or equal to a threshold has been detected than when the specific driving operation state has not been detected. When the specific driving operation state has been detected, the hybrid vehicle increases the updating rate of a concentration learned value of fuel vapor gas, and decreases the rate of increase in target purge rate.
