Vehicle transmission shift control apparatus wherein torque of motor connected to automatic transmission is controlled to reduce shifting shock of transmission

摘要

A shift control apparatus for controlling a variable-speed ratio automatic transmission of a motor vehicle having an engine, and a motor/generator which function as a vehicle driving electric motor and/or an electric generator, the automatic transmission being operatively connected to a drive wheel and an assembly of the engine and the motor/generator, the shift control apparatus including a target determining device for determining a pattern of change of a target value of the rotating speed of a rotary member of the automatic transmission or a target value of the output torque of the automatic transmission, during a shifting action thereof, and a motor torque feedback control device for feedback controlling a torque of the motor/generator during the shifting action of the automatic transmission such that the rotating speed of the rotary member or the output torque changes according to the pattern of change of the target value.
