摘要： PROBLEM TO BE SOLVED: To improve shift change speed performance in manual shift change in a twin clutch type transmission or the like in which a plurality of rotation power transmission systems are provided in parallel between an input shaft and an output shaft. SOLUTION: By moving a shift lever 8a to pre-shift positions PrU Pp and PrDNp, a transmission mechanism belong to the rotation power transmitting system on the clutch released side can be changed to a corresponding gear shift state without actually executing shift change. In giving an instruction for a shift change actually, sleeve driving time inside the transmission mechanism is not necessary. At timing when the shift lever 8a is moved to an up-shift position UPp or a down-shift position DNp, therefore, clutch-to-clutch operation can be executed speedily, and gear change can be completed in an early stage. Shift change speed performance in manual shift change can thus be improved. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a control device for a vehicular transmission in a power transmission passage ranging from an engine to a driving wheel, automatically coping with the irregularity of a control hydraulic pressure sensor for detecting driving control hydraulic pressure of an automatic shift control device.
SOLUTION: When finding the irregularity of the control hydraulic pressure sensor for detecting driving control hydraulic pressure P
B of the automatic shift control device using the discharge pressure of a hydraulic pump as original pressure, the original pressure P
A is automatically lowered. This suppresses the lower controllability of the automatic shift control device with high pressure due to the impossible control of the driving control hydraulic pressure P
B and prevents the application of shifting overload. For example, this suitably prevents damage to the transmission due to too strong shifting operation force or selecting operation force.

摘要： PROBLEM TO BE SOLVED: To provide a selection controller for the transmission of a vehicle. SOLUTION: The selection controller for the transmission of the vehicle is structured so that one of the engagement part and the part to be engaged of a select position deciding mechanism has a mechanical converging region in which the relative positioning of the engagement part and the part to be engaged is changed even if an actuator is out of drive and the degree of engagement of the engagement part with the part to be engaged is increased mechanically. A selection control means executes two operations, one to drive the actuator so that the relative positioning of the engagement part and the part to be engaged is put in relative movement on the basis of the target stroke in the direction of increasing the degree of engagement of the engagement part with the part to be engaged and the other to stop the drive of the actuator or decelerate when the relative positioning of the engagement part and the part to be engaged reaches the mechanical converging region and increase the degree of engagement using the mechanical converging region.

摘要： PROBLEM TO BE SOLVED: To enable speed change of a torque transmission system in a side of a clutch drive actuator which stops by a failure or the like in a multiple clutch type transmission. SOLUTION: When one of master cylinder drive mechanisms MD1, MD2 can not be actuated, e.g. failure of clutch motors CMR1, CMR2 due to break of a wire or failure of clutch stroke sensors 12, 14 is caused, a normal master cylinder drive mechanism is actuated to connect the master cylinder drive mechanisms MD1, MD2 with an interlock mechanism IL. The failed master cylinder drive mechanism is actuated by the normal master cylinder drive mechanism to jointly engage and disengage both clutches. By executing failed transmission control process, actuation of the master cylinder drive mechanism enables speed change of the stopped torque transmission system. Consequently, the case that saving travel can not be carried out can be avoided. COPYRIGHT: (C)2004,JPO
