Method of reducing shift hunting in automatic vehicle transmissions via reduction of motor torque

摘要

The control device for the gearbox monitors the current resistance to forward motion of the motor vehicle by comparing the measured vehicle acceleration with a theoretical vehicle acceleration in order to determine the value for an acceleration difference. Engine torque is regulated if the vehicle accelerator pedal position is greater than a limiting value, if the acceleration difference is greater than a limiting value and if measured vehicle acceleration is greater than a positive limiting value.
