摘要： There is provided a starting clutch control apparatus which is capable of controlling transmission torque of a starting clutch according to changes in accelerator operated amount without preparing a plurality of data maps of torque coefficients in advance. A clutch controller determines a clutch instruction torque based on torque coefficient, engine speed, and engine speed correction amount, and controls the engagement state of the starting clutch according to the clutch instruction torque. Therefore, it is possible to control the engagement state of the starting clutch in response to sudden operation of an accelerator, and to finely control the degree of engine blow-up according to an accelerator operated amount. Only one data map for determining the torque coefficient according to a rotational speed ratio of a clutch input shaft to a clutch output shaft is required to be stored in a data storage section, and hence it is possible to prevent an increase in the amount of data stored in the data storage section.

摘要： An automatic transmission control apparatus is provided with a control scheme that focuses on the rotational speed differences of the frictional engaging elements and the distribution of torque transferred by the frictional engaging elements. When the automatic transmission is upshifted while in a power-off state, the individual torque capacity of a frictional engaging element being released and the individual torque capacity of a frictional engaging element being connected are corrected by adding a prescribed torque capacity amount to each of the individual torque capacities during an inertia phase of the shift control in which a compensation is executed for inertia related to changing the gear ratio. In this way, frictional losses are induced in the frictional engaging elements so as to absorb the inertia torque and lower the input rotational speed more quickly.

摘要： An automatic transmission includes at least an input section, an output section, first and second frictional engagement elements, and a controller. The input section receives an input torque from a drive unit. The first frictional engagement element has an engaged state allowing the output section to rotate at a first transmission gear ratio with respect to the input section. The second frictional engagement element has an engaged state allowing the output section to rotate at a second transmission gear ratio with respect to the input section. The controller controls at least a gear shift from the first transmission gear ratio to the second transmission gear ratio. The controller controls the first and second frictional engagement elements and the drive unit so as to cancel an inertia torque resulting from the gear shift.
