摘要: In a transmission, a controller sets a target line pressure to an offset target value, which is a value obtained by adding a positive offset amount to one of a target PRI pressure and a target SEC pressure, in a speed ratio range in which the offset target value is higher than the other at least during an inertia phase in a sub-transmission mechanism when a coordinated shift is carried out. At that time, the one of the target PRI pressure and the target SEC pressure is the target SEC pressure when a variator is downshifted by the coordinated shift while being the target PRI pressure when the variator is upshifted by the coordinated shift.

摘要: A method (200) for open-loop control of a gearbox (100) that includes a first and a second proportionally controllable shift element (A-F) is provided. The method (200) includes disengaging the first shift element (A-F) of the gearbox (100) according to a first control profile and engaging the second shift element (A-F) of the gearbox (100) according to a second control profile. The first control profile comprises a variable portion (330) which is increased between a first point in time (t4), when a gradient (335) of the rotational speed of an input shaft of the gearbox (100) reaches a predetermined threshold value, and a second point in time (t5), when the gradient (335) flattens.

摘要: A method (200) for the open-loop control of a gearbox (100) that comprises an input shaft (105) and a first and a second proportionally controllable shift element (A-F) is provided. The method includes disengaging (215) the first shift element (A-F) according to a first control profile and engaging (220) the second shift element (A-F) according to a second control profile. The method also includes cyclically performing the following during the disengagement and the engagement: determining (230) a difference between the rotational speed of the input shaft (105) and a rotational speed which the input shaft (105) assumes when the second shift element (A-F) has been completely engaged; determining (230) a gradient of the difference; and adapting (230) the first control profile on the basis of the gradient.

摘要: When a power-on downshift via an intermediate shift stage accompanied by input switching control is required and a predetermined shift stage is a shift stage lower than the intermediate shift stage, an electronic control unit performs torque phase control in a torque phase control time shorter than the torque phase control time that is set when the predetermined shift stage is a shift stage higher than the intermediate shift stage. Accordingly, it is possible to complete disengagement of a disengagement-side element early and to suppress a rapid increase of an input shaft rotation speed due to a clutch torque remaining.

摘要: A control device for an automatic transmission is provided. The automatic transmission is configured to realize a plurality of gear shift stages by combination of a plurality of engaging devices engaged or released among the plurality of engaging devices. The control device includes an electronic control unit. The electronic control unit is configured to select, as the setting pattern realizing an intermediate gear shift stage, the setting pattern with a smaller number of switching of the engagement or release of the engaging device than the number of switching of the setting pattern with the largest number of switching among the plurality of setting patterns when a shift is performed from a first gear shift stage to a second gear shift stage through the intermediate gear shift stage in a case where the electronic control unit determines that the shift is to be performed through the intermediate gear shift stage.
