SHIFT CONTROL DEVICE FOR VEHICLE

摘要

Provided is a shift control device for a vehicle, constructed so as to reduce shift shocks in clutch-to-clutch shifting. With a transmission, wherein multiple gear ranges are set in accordance with the engagement and release states of multiple engagement mechanism capable of continuously changing the torque capacity, being connected to the output side of a power supply, this shift control device for a vehicle performs clutch-to-clutch shifting that switches from a prescribed gear range to another gear range by gradually reducing the torque capacity of a prescribed engagement mechanism so as to release the prescribed engagement mechanism and gradually increasing the torque capacity of another engagement mechanism so as to engage this other engagement mechanism. In addition, this shift control device for a vehicle is equipped with a torque calculation means (step S6) that calculates the target torque capacity for the engagement-side engagement mechanism in the torque phase and the inertia phase during clutch-to-clutch shifting, on the basis of the target input angular acceleration of the transmission, the target output angular acceleration of the transmission, and the target torque capacity and target output torque of the release-side engagement mechanism. The target torque capacity of the release-side engagement mechanism is set to a value that changes continuously from the torque phase to the inertia phase during the clutch-to-clutch shifting.
