ABSTRACT:
An automotive shift change control system and automatic transmission system is provided to give passengers a comfortable feeling of shift changing or of driving. A transmission connects a vehicle-driving engine, an electrical rotary machine, and axles via a differential gearbox, transmits the power of the engine to the axles via the electrical rotary machine during a shift change, and conducts the shift change. The automotive shift change control unit that controls the change gear ratio of the transmission includes a driving force controller to control the driving force of the electrical rotary machine, a shift-changing speed controller to send a driving force command from the electrical rotary machine to the driving force controller, and a target shift-changing speed changeover device to output the target shift-changing speed that becomes a target value of the shift-changing speed controlled by the shift-changing speed controller.
