<P>PROBLEM TO BE SOLVED: To provide a control method for driving force transmission device in a hybrid vehicle, preventing the generation of a shock due to sudden engagement of a two-way clutch when the vehicle travels in the reverse direction. <P>SOLUTION: The control method for driving force transmission device in a hybrid vehicle includes: a front wheel taking an engine as a driving source and a rear wheel taking an electric motor with a speed reducer as a driving source, wherein a mechanical two-way clutch 19 is built in a torque transmission passage extending from an output shaft 18 of the electric motor to the rear wheel, thereby preventing turning torque from being transmitted from the rear wheel to the output shaft 18 when a vehicle is traveled by the engine. During traveling on a uphill slope by the drive of the engine and the electric motor, the vehicle is once stopped, and in again traveling in the same direction, when the vehicle is traveled in the reverse direction by its dead load, the electric motor is driven in the direction opposite to the reverse traveling direction, whereby load torque more than the engagement release torque of a sprag 24 of the two-way clutch 19 is applied to an outer ring 22 of the two-way clutch 19. <P>COPYRIGHT: (C)2009,JPO&INPIT |
