Abstract
A vehicle transmission system has a gear-type transmission with a plurality of gears and a plurality of claw clutches which transmits a torque between an input shaft of said gear-type transmission and an output shaft of said gear-type transmission. The transmission changes transmission courses by engaging with and/or disengaging from the gears and the claw clutches, and forms another transmission course via a torque controller between the input shaft of the gear-type transmission and the output shaft of said gear-type transmission during a period between a first transmission course and a second transmission course formed by the gears and the claw clutches. A torque capacity of the torque controller is greater than the maximum output shaft torque of the transmission.
