(Subject) To provide an automotive shift change control system and automatic transmission system capable of giving to passengers a comfortable feeling of shift changing or of driving. [Means of Solution] A transmission 100 connects a vehicle-driving engine 1, an electrical rotary machine 5, and axles via a differential gearbox 31, transmits the power of the vehicle-driving engine 1 to the axles via the electrical rotary machine 5 during a shift change, and conducts the shift change. The automotive shift change control unit 200 that controls the change gear ratio of the transmission 100 includes a driving force controller 210 to control the driving force of the electrical rotary machine 5, a shift-changing speed controller 220 to send a driving force command from the electrical rotary machine 5 to the driving force controller 210, and a target shift-changing speed changeover device 230 to output the target shift-changing speed that becomes a target value of the shift-changing speed controlled by the shift-changing speed controller 220.
An automotive controller for shift changes, used with, and adapted to control a change gear ratio of, a transmission to connect a engine for vehicle driving, an electrical rotary machine, and axles via a differential gearbox, and conducts a shift change by transmitting power from the vehicle-driving engine to the axles via the electrical rotary machine during the shift change, wherein
An automatic transmission system of an automobile, comprising:
