Abstract
In a hybrid vehicle provided with a power dividing mechanism comprising a clutch mechanism, an ECU performs speed-change control. In the control, the ECU performs an engage preparing process if it is necessary to engage clutch plates of the clutch mechanism with each other. In the process, the ECU switches a reference value which is referred in a feedback control for performing a rotation synchronization and a position synchronization for the clutch plates from a calculated value which is calculated from a pulse signal of first rotational sensor mounted the clutch plate to an estimated value which is estimated from a pulse signal of each of second and third rotational sensors for detecting rotational speed of each motor generators if clutch rotational speed as rotational speed corresponding to the clutch plate as an engagement element decreases to less than a criterion value.
