<P>PROBLEM TO BE SOLVED: To provide a transmission system for a hybrid vehicle, which has improved mountability on a vehicle by reducing the size and weight, switches from forward traveling to backward traveling without hindering smooth gear shifting through a continuously variable transmission mechanism, and reduces costs. <P>SOLUTION: The transmission system for the hybrid vehicle includes: a continuously variable transmission mechanism 7; and an input side transmission shaft 4 for transmitting rotation from one or both of an internal combustion engine 2 and a motor 3. The input side transmission shaft 4 is provided with: a forward drive gear 10 and a backward drive gear 11 that are freely rotatable; and a switching connection means 12 for connecting the forward drive gear 10 or the backward drive gear 11 to the input side transmission shaft 4. The transmission system further includes a switching control means. When the forward traveling is set instead of the backward traveling by the switching connection means 12, the switching control means forcibly synchronizes the rotation of the input side transmission shaft 4 with the rotation of the backward drive gear 11 according to the driving of the motor 3 after the forward drive gear 10 is disengaged from the input side transmission shaft 4 and before the backward drive gear 11 is connected to the input side transmission shaft 4. <P>COPYRIGHT: (C)2010,JPO&INPIT |
