Abstract
A hybrid control controller stores vehicle speed influence values that have been set according to vehicle speeds, a first threshold value of a sum value of the vehicle speed influence values, a second threshold value lower than the first threshold value, and an engine start reference vehicle speed, and during EV running, sums the vehicle speed influence values from moment to moment. The hybrid control controller starts the engine in a case where the sum value is no less than the first threshold value, and in a case where the sum value is no less than the second threshold value and the vehicle speed is no more than an engine start reference vehicle speed.
