Abstract :
In this paper, the integrated powertrain control system is discussed which receives input and output speeds of the transmission, the engine speed, and the accelerator pedal position and uses this information to adjust engine torque and speed to effect a shift of the automatic transmission. The optimum model is given in this paper which has been tested. The automatic transmission loaded by an inertia flywheel and high-pressure pump, powered by diesel, and controlled by an electronic system, is the object of this test. The result shows an improvement of shift quality in most cases. The test proves that the integrated control can reduce the jerk
