Disclaimer (all) which will not appear on the advertisement page. : ------ 04/01/2019 ------ (OCR) Page 1 of amount 1 page. 1.Control devices for automatic transmission The control device is applied to the stepless automatic transmission. Where the multiple shifts in it are determined by selecting multiple friction overlapping elements to perform time-torque phase control, target torque phase. Control equipment, which has the characteristics that The target torque phase time during automatic transmission gear changes is determined by the difference in output shaft torque between before and after gear shifting. And the torque phase control is performed according to the predetermined target torque phase time and when the automatic gearshift is downshift to drive. The upper limit of the target torque phase time is then determined by the set torque directed by the discharge side element in the torque phase and the difference in the speed of rotation of the input shaft between the rotational speed. Of the input shaft before and after changing gears 2.
