Abstract
A hybrid vehicle is able to select series-parallel mode by engaging a clutch (C) or a brake (B) and releasing a clutch (CS), and is able to select series mode by releasing both the clutch (C) and the brake (B) and engaging the clutch (CS). The hybrid vehicle includes a simultaneous supply prevention valve () that prevents simultaneous engagement of the clutch (CS) and at least one of the clutch (CI) or the brake (B). When a signal pressure of at least one of hydraulic pressure for engaging the clutch (C) or hydraulic pressure for engaging the brake (B) is input to the simultaneous supply prevention valve (), the simultaneous supply prevention valve () is switched to a state where supply of hydraulic pressure to the clutch (CS) is cut off.
