摘要： A method is disclosed for operating a multi-gear vehicle transmission in a motor vehicle during a coasting phase. The coasting phase includes an overrun phase with a driving gear engaged and a freewheeling phase with the neutral gear engaged. It is determined whether the motor vehicle is in the overrun phase of the coasting phase, whether a condition for a transition to the freewheeling phase of the coasting phase is fulfilled, and whether a transmission condition with elevated drag losses exists. If the motor vehicle is in the overrun phase of the coasting phase, if the condition for transition to the freewheeling phase is fulfilled, and if a transmission condition with elevated drag losses exists, then at least one further shifting element (D, E) is closed in addition to the shifting elements (A, B, C) of the driving gear, which are closed during the overrun phase of the motor vehicle.

摘要： A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

摘要： A transmission control system of a vehicle includes an estimated acceleration module and a pressure control module. The estimated acceleration module determines an estimated longitudinal acceleration of the vehicle based on a force at axles of the vehicle corresponding to engine torque, a braking force imposed by mechanical brakes of the vehicle, an aerodynamic drag force of the vehicle, and a road load force imposed on the vehicle by contact between tires of the vehicle and a road surface. The pressure control module, when a measured longitudinal acceleration of the vehicle is negative and the estimated longitudinal acceleration is greater than the measured longitudinal acceleration of the vehicle, adjusts transmission fluid pressure applied to one or more clutches of the transmission and shifts the transmission to neutral.

摘要： Methods for machine velocity change gear selection and shift execution are disclosed. A current velocity and a maximum velocity change for a work machine from the current velocity may be determined. The maximum velocity change may be based on a maximum amount of energy expended to change the velocity of the work machine without exceeding an operational limit of a work machine component. A selected machine velocity change target gear may be a highest one of the available gears that will not cause a difference between the current velocity and an end of shift velocity of the work machine that is greater than the maximum velocity change so that the maximum amount of energy will not be exceeded. Factors affecting the maximum velocity change may include the grade, the mass of the work machine, and a transmission oil temperature.

摘要： In vehicles designed to pick up and process crops, drive units affect the ground drive, which is an all-wheel drive, which acts on all of the wheels and/or track roller unit in contact with the ground, electronic controls and actuators perform the control and regulation of the drive units, and control units that control the drive torque at the wheels are used to obtain good traction and minimal slippage of the wheels on the ground. To control the drive torques, sensors are used at particular points, the signals and data of which are processed by the control device in order to predetermine a torque or intake volume requirement. The preselection of torque in the control results in the intake volume of the hydraulic drive motor being regulated. By specifying the intake volume required, it is possible to obtain optimal traction at one or more drive wheels, and to prevent undesired slippage of any one drive wheel in advance.

摘要： A method for control of a vehicle gearbox which is automatically controlled by a control system. The control system's choice of transmission ratio is influenceable by the vehicle's driver. The control system chooses an initial transmission ratio for moving off stationary. The method includes determining a first initial transmission ratio by using the control system, and determining a second initial transmission ratio indicated by the vehicle driver. The gearbox is set to the second initial transmission ratio indicated by the driver when the second ratio is higher than the first initial transmission ratio determined by the control system.

摘要： A transmission control apparatus includes transmission lines disposed between a pair of transmission shafts and a hydraulic multiple disc transmission clutch disposed on one side of the transmission lines. Power from an engine is transmitted via one of the transmission lines to a traveling unit. Each of the transmission lines has a friction clutch. A first gear mechanism operated by a first actuator is disposed between one of the transmission shafts and the first transmission line. A second gear mechanism operated by a second actuator is disposed between one of the transmission shafts and the second transmission line. When the first transmission line is powered, a first system operates the second gear mechanism into a speed position; the first clutch to a non-transmitting state and the second clutch to a transmitting state, thereby providing a progressive shifting of the transmission clutch from a transmitting state to a semi-transmitting state.
