  • Patent number: 9206894
    Abstract: One of two clutches etc. engaged concurrently with each other to establish a second speed, a third speed, or a fourth speed is determined in advance as an abnormal-time engagement element that is kept engaged when an abnormality occurs in which one different clutch or brake is engaged during concurrent engagement of the two clutches etc. The other of the two clutches etc. is determined in advance as an abnormal-time slipping element that is caused to slip when such an abnormality occurs. During concurrent engagement of the two clutches etc., a hydraulic pressure (target hydraulic pressure) to be supplied to the abnormal-time engagement element is set to be higher than a hydraulic pressure (target hydraulic pressure) to be supplied to the abnormal-time slipping element.

  • Patent number: 6055475
    Abstract: In a transmission control apparatus and a transmission control method for an automatic transmission, when a detection point is defined in accordance with results of detection by means of a fluid temperature detecting element and a rotational speed detecting element, a plurality of points that surround the detection point are selected among a plurality of preset points. Control values for a control parameter are previously mapped corresponding to the set points, and the control values corresponding to the selected points are read from the resulting map. The controlled variable of the control parameter corresponding to the detection point is appropriately linearly calculated by interpolating the control values. Further, a learning correction value for the control parameter corresponding to the detection point is calculated, and is reflected in the control values for the selected points.
