PROBLEM TO BE SOLVED: To provide a hybrid vehicle that can select a series travel mode and a series-parallel travel mode, which suppresses occurrence of shock.SOLUTION: A hybrid vehicle can select a series-parallel travel mode by engaging a clutch C1 or a brake B1 and releasing a clutch CS, and can select a series travel mode by releasing both clutch C1 and brake B1 and engaging the clutch CS. The hybrid vehicle comprises a simultaneous supply preventing valve 550 that prevents at least either one of the clutch C1 and the brake B1 from simultaneously engaging with the clutch CS. The simultaneous supply preventing valve 550 can be switched into a state in which hydraulic pressure supply to the clutch CS is interrupted when at least either one signal pressure of C1 pressure for engagement of the clutch C1 and B1 pressure for engagement of the brake B1 is inputted thereto.SELECTED DRAWING: Figure 4 |
