摘要:
A method comprises a pre-charge step of pre-charging operating oil; a holding step of holding an operating pressure at an oil pressure less than an oil pressure during the pre-charge, for a given period of time; and a raising step of raising the operating pressure to cause an engagement-side friction element to be engaged. The method further comprises a setting step of setting a pre-charge period in the pre-charge step. The setting step includes predicting a timing at which the engagement-side friction element is to be engaged; actually measuring a timing at which the engagement-side friction element has been actually engaged; and setting the period of the pre-charge step to allow a difference between the timings to become smaller.

In a transmission network of a multi-hop connection in which a transmission bandwidth between relay stations changes, it is possible to prevent congestion from occurring due to a change in the transmission bandwidth between the relay stations. A transmission device connected to a network constituted of a plurality of relay stations includes a transmission section configured to transmit a signal to the network, and a bandwidth control section configured to control a transmission bandwidth of the transmission section based on a lowest transmission bandwidth among transmission bandwidths between the relay stations.
摘要:
When a first communication device receives a predetermined message from a second communication device via a third line (L3) in a state of transmitting frames to a first line (L1) while performing error-correction coding on the frames, the first communication device switches the line used for transmission from L1 to the second line (L2), then transmits a frame of a post-switching message to L1. The second communication device receives frames from L1 and L2 and performs error correction, stores the frames, on which error correction has been performed, in first and second buffers (B1, B2), and when determining that it is necessary to perform line switching based on the status of error correction with respect to the frames received from L1, transmits a predetermined message to L3, and when receiving the frame of the post-switching message from L1, starts reading frames from B2 after reading all frames stored in B1.

摘要:
In an automatic transmission (AT) in which an input shaft (Input) and an output gear (Output) are disposed on the same axis and three clutches (C1-C3) and two brakes (B1, B2) are selectively operated to provide six forward speeds, first and second planetary gear sets (GS1, GS2) are configured to consistently reduce the speed of input rotation and output the speed-reduced rotation, thereby enabling downsizing of them. The first and second planetary gear sets (GS1, GS2) are arranged in a transmission case at both the axial ends thereof. Third and fourth planetary gear sets (GS3, GS4) are connected to each other to have four rotation elements in combination, thereby constituting a Simpson planetary gear train. One of the four rotation elements (a fourth carrier (PC4) in an illustrated example) is connected to the output gear (Output). Rotations input and reduced in speed by the first and second planetary gear sets (GS1, GS2) are input to sun gears (S3, S4) of the third and fourth planetary gear sets (GS3, GS4), respectively. First to third clutches (C1-C3) and a first brake (B1) are arranged to surround the first and second planetary gear sets (GS1, GS2).
