    摘要: A method of engaging and disengaging transmission gears in a vehicle is provided. A controller processes an initial torque representing an engine torque and an estimated zero torque representing an estimate of a transmission output shaft torque. The controller also sets a high and low band torque about the estimated zero torque. Once the above torques have been determined, the controller compares the initial torque to the high band torque. If the initial torque is below the high band torque, the controller increases the engine torque to the high band torque. If the initial torque is greater than the high band torque, then no preliminary adjustments to the engine torque need be made. At least one shift valve is energized when the engine torque is equal to or greater than the high band torque. The engine torque is decayed by the controller to the low band torque to facilitate engaging and disengaging transmission gears.

    摘要: A process for the control of non-synchronized, manually shiftable vehicle transmissions which are actuated in vehicles of new construction by means of an automated transmission control system whereby the driver is able to select a desired gear by means of an operating unit which is connected electrically to the transmission control system. When the vehicle is stopped and the clutch is disengaged practice of the invention prevents a situation in which the engagement of a gear is prevented by a tooth-on-tooth position of the transmission claws. The disclosed process makes it possible to engage the selected gear in all operating states of the vehicle in a simple and reliable manner. In this regard, a desired gear is first selected, and the clutch is then disengaged. When a suitable speed of the transmission input is then reached, a gear to be engaged is automatically engaged. Thereby, the engagement of a gear when the vehicle is stopped is systematized and facilitated for the driver. Furthermore the driver need not disengage and then again engage the clutch repeatedly in order to avoid a tooth-on-tooth position. The process is used preferably in utility vehicles.
