Embodiment approach

[0051] Hereinafter, embodiments of the present invention will be described in detail with examples. However, the constituent elements described in this embodiment are merely examples, and the technical scope of the present invention is defined by the claims, and are not limited by the following individual embodiments.

[0052] A shift control device for an automatic transmission according to an embodiment of the present invention will be described. figure 1 It is a figure which shows the schematic structure of the automatic transmission concerning embodiment. exist figure 1 In , reference sign T denotes a transmission. As the transmission T, a dual-clutch type transmission having eight forward speeds and one reverse speed, which is mounted on the vehicle 1 , is taken as an example. The transmission T has gears of D, P, R, and N.

[0053] The transmission T is connected to a drive shaft 10 a of an engine (prime mover: E) 10 through a torque converter 12 , wherein the drive ...

Abstract

An automatic transmission control device for automatic transmission is formed to make the input shaft rotary transmission and output to the output shaft. The transmission control device has: input detection department, which detects the actual rotation of the input shaft;The actual rotation of the output shaft; the presumption department, through the actual rotation of the output shaft multiplied by the target transmission ratio to correct the input shaft corresponding to the input shaft;The result to control the rotation of the input shaft.The control department controls the rotation of the input shaft, so that the upper limit of the deviation of the actual rotation of the input shaft is lower than that of the positive rotation.

Description

technical field [0001] The invention relates to a speed change control device of an automatic transmission. Background technique [0002] Japanese Patent Application Laid-Open No. 4029875 discloses a structure of a vehicle control device for controlling engagement of dog clutches during gear shifting. In this structure, the internal teeth and the external teeth are brought into engagement by simultaneously performing the control to move the sleeve 21 in the axial direction and the control to rotate the sleeve 21 . [0003] However, in the structure of Japanese Invention Patent Granting Publication No. 4029875, the chamfer (chamfer) 38 and the chamfer 39 are in contact, and the internal teeth and the external teeth are engaged while sliding, thereby causing The sleeve 21 moves in the axial direction and the required load of the actuator required to engage the sleeve 21 to rotate increases. Contents of the invention [0004] In view of the above-mentioned technical problem...
