Abstract
An apparatus for controlling a hybrid vehicle with a power transmitting system including a transmission and a planetary gear device having a first rotary element connected to a first drive power source such as an engine, a second rotary element connected to a second drive power source and to the transmission through a first clutch, and a third rotary element connected to the transmission through a second clutch, the apparatus including a neutral-mode determining device operable when the first and second clutches are in a released state, for determining whether the power transmitting system is placed in a first or a second neutral state, depending upon which one of the first and second clutches is to be engaged when a driving of the hybrid vehicle is subsequently initiated, a first synchronizing device operable when the power transmitting system is placed in the first neutral state, for synchronizing speeds of a pair of friction members of the first clutch with each other, and a second synchronizing device operable when the power transmitting system is placed in the second neutral state, for synchronizing speeds of a pair of friction members of the second clutch with each other.
