    摘要: A system for shifting a transmission includes an off-going clutch, an on-coming clutch, and an assisting clutch. A controller is configured to increase an amount of torque carried by each of the on-coming clutch and the assisting clutch. The controller is further configured to reduce an amount of torque carried by the off-going clutch and, after the off-going clutch is disengaged, to reduce the amount of torque carried by the assisting clutch.

    摘要: A transmission control device includes even-numbered and odd-numbered transmission gears selected via a shift mechanism and causes the torque capacities of two clutches to be transitioned to a certain proportion until the clutch rotation speed difference of a low-speed gear-side clutch reaches 0 or approximately 0, sets the torque capacity of the clutch on the low-speed gear side to be the total torque capacity of both clutches, and sets the torque capacity of the clutch on the high-speed gear side to 0. The heat load on the clutch at the time when the vehicle starts to move is reduced and the durability thereof is improved, and the clutch can be made smaller and lighter.

    摘要: In a gear shift control apparatus for a vehicle, since a torque sharing rate is set as a constraint for a motion equation for an automatic transmission, suitable control in torque delivery, which is considered difficult in gear shift control, can be implemented and also the motion equation can be solved. Furthermore, when at least four control operation amounts must be determined in order to achieve two gear shift target values, another engaging device is classified into any of an engaging-side clutch and a releasing-side clutch depending on how another clutch torque acts on progress of a gear shift, hence in addition to achieving torque sharing in accordance with a torque sharing rate between the engaging-side clutch and the releasing-side clutch, torque sharing among a plurality of engaging devices classified into a same side can be arbitrarily set. As a result, the respective control operation amounts can be determined.
