    摘要: A shift control system is provided that is suitable for semi-automatic transmissions in heavy duty vehicles. The torque modulation system includes logic circuitry that employs a ramping torque function or algorithm to control the acceleration of torque, both positive and negative, and/or provides a longer dwell time in the torque clutch disengagement range. Moreover, dwell time at peak is not required. A method for improving gear disengagement and shift control in accordance with the principles of the invention is also disclosed.

    摘要: A method for determining a driveline ratio for a powertrain having an auxiliary transmission is provided and includes identifying a transmission gear ratio, measuring a transmission output speed, and measuring an auxiliary transmission output speed. An auxiliary transmission gear ratio is identified by comparing the transmission output speed to the auxiliary transmission output speed when the powertrain is in motion. The auxiliary transmission gear ratio is identified from a switch when the powertrain is at rest. An auxiliary transmission module has an auxiliary transmission in communication with a controller. The controller is configured to identify an auxiliary transmission gear ratio, and limit an engine torque command to limit the auxiliary transmission output torque. The engine torque command is limited if the output torque exceeds a predetermined value and if the auxiliary transmission is in a reducing gear ratio.

    摘要: An engine-transmission control system is disclosed which provides for variable shift points of a manual/automatic transmission during cruise control and non-cruise control operation of the vehicle. Vehicle speed, engine speed, and engine loading are variables used individually or in combination in order to determine when shifting of the automatically controllable gear ratio operation states of the manual/automatic transmission will occur. In addition, the system includes modes of operation which include algorithms for determining varying gear shift points so that gear shifting of the top two gears occurs at various vehicle speeds dependent upon input parameters to the cruise control system and additionally in response to which cruise control mode of operation is currently selected by the driver. In addition, control of the automatic shifting of the manual/automatic transmission when the cruise control system is inactive or disabled is determined according to algorithms designed to optimize fuel economy as well as improve driveability of the vehicle and reduce driver fatigue.
