A vehicle control device includes a control device that performs synchronization control of a synchronization mechanism on a vehicle, the vehicle including an input shaft, an intermediate shaft to which rotational power is transmitted, a shift gear that is synchronized with the intermediate shaft, and a synchronization mechanism that synchronizes the input side synchronization element with the output side synchronization element, and the control device includes a first synchronization mode in which the differential rotation is calculated on the basis of the rotational speed of the intermediate shaft, and a second synchronization mode in which the differential rotation is calculated on the basis of the rotational speed of the input shaft, and performs synchronization control in the first synchronization mode when performing the synchronization control, and performs the synchronization control in the second synchronization mode in a case in which the synchronization control does not proceed.

Control device for vehicle

A dual clutch automatic transmission includes a one-way clutch provided in a driving force transmission path that establishes a first certain gear ratio in a first set of gear ratios. A driving transmission direction of the one-way clutch is set such that a rotation inputted from a wheel side to an output member in a predetermined rotational direction is transmitted to the input shaft. The predetermined rotational direction corresponds to a backward movement of a vehicle. If an off-gear operation cannot be performed for a transmission gear with interlock, the driving force of the driving source is input to the input shaft to enable the off-gear operation.

Automatic transmission and control method of automatic transmission

A vehicle makes a notification to prompt a driver to perform a predetermined operation in a case in which a predetermined function of the vehicle is lost, and starts a recovery operation of the function on condition that the predetermined operation is performed.

A MODEM can shorten the processing time of an interface disposed between a data terminal equipment (DTE) and the MODEM. The MODEM stores an object program of a procedure in a memory and switches an operational mode of the MODEM automatically corresponding to the prescribed procedure thereby executing the procedure corresponding to the current operational mode. The MODEM further comprises a timer which monitors the transits time between a completed procedure and the next procedure, and the MODEM starts the process of a specified operational mode based on a mode-setting-instruction of the procedure as well as monitoring the transitions time by using the timer, and executing a next specified operational mode when the timer times out, thereby allowing the MODEM to perform the various operational mode switches.

Modulator and demodulator (MODEM)

When the present modem control apparatus detects that the receive level of a probing signal in phase 2 of the pre-communication procedure or a tone signal with a specific frequency in phase 2 of the pre-communication procedure is lower than a prescribed value, it sets the transmission rate of the control channel to a low rate of 1200 bps. In this case, the modem control apparatus sets the transmission rate to 1200 bps through a prescribed bit of the MPh signal in the communication control procedure and performs the setting that will not permit communications with the answer modem at different transmission rates, through the second prescribed bit of said MPh signal, and notifies those settings to the answer modem, thus carrying out communications at a lower transmission rate.

Method for controlling modem

A digital signal detection circuit includes a threshold value calculator calculating a threshold value from assumptive sampled values corresponding to various data patterns of a regenerated signal. The regenerated signal is obtained by regenerating data recorded on a recording medium by a regenerating head. The detection circuit also includes a Viterbi decoder carrying out Viterbi decoding of the regenerated signal with the threshold value determined by the threshold value calculator as a constant. The threshold value calculator variably controls the threshold value using a decoded output of the Viterbi decoder and a regenerated signal corresponding to the decoded output of the Viterbi decoder.
