(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.
