Abstract
In a hybrid vehicle, an ECU performs speed-change control and selectively changes a speed-change mode between a stepless speed-change mode and a fixed speed-change mode in accordance with the travel condition of the hybrid vehicle. At this time, in the condition that the fixed speed-change mode is selected, if an accelerator off operation is performed, a release preparing process is performed, and a reaction element which receives the reaction torque of engine torque in a power dividing mechanism is changed to a sun gear on a motor generator side. Moreover, if an accelerator off speed or a brake pedal operation amount exceeds its own reference value, the speed-change mode is transferred into the stepless speed-change mode, predictively and unconditionally, before a normal speed-change condition is met.
