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.

1. A vehicle control apparatus for controlling a hybrid vehicle of a type which comprises a first drive power source, a second drive power source, and a power transmitting system including a transmission and a planetary gear device having a first rotary element connected to said first drive power source, a second rotary element connected to said second drive power source and further connected to said transmission through a first clutch, and a third rotary element connected to said transmission through a second clutch, said first clutch including one pair of friction members connected to said first rotary member and said transmission, respectively, said second clutch including one pair of friction members connected to said third rotary element and said transmission, respectively, said vehicle control apparatus further comprising:neutral-mode determining means operable when said first and second clutches are both placed in a released state, for determining whether said power transmitting system is placed in a first neutral state or a second neutral state, depending upon which one of said first and second clutches is to be engaged when a driving of said hybrid vehicle in a vehicle drive mode is subsequently initiated; first synchronizing means operable when said neutral-mode determining means has determined that the power transmitting system is placed in said first neutral state, for synchronizing speeds of said one pair of friction members of said first clutch with each other; and second synchronizing means operable when said neutral-mode determining means has determined that the power transmitting system is placed in said second neutral state, for synchronizing speeds of said one pair of friction members of said second clutch with each other.
