Title: Manual shift control device of automatic transmission
Inventor: OYAMA HAJIME
IPC: F16H61/18
Filed: 2016-03-14
Abstract: PROBLEM TO BE SOLVED: To improve a shift responsiveness in a manual shift mode of an automatic transmission and prevent shifting not according to a driver's intention (especially, two-stage shifting) accompanied by automatic shifting-up or shifting-down, by making shifting according to a driver's intention carried out in an early stage.SOLUTION: When an action speed of a shifting-up action (a shifting-down action) of a manual shift action member in the middle of a shift action is equal to or more than a predetermined shifting-up determination value (predetermined shifting-down determination value), a shifting command for a shifting-up (shifting-down) is output to an automatic transmission (step S7). Even when the above action speed is equal to or more than the shifting-up determination value (shifting-down determination value) during an automatic shifting-up or shifting-down in a manual shifting mode, the shifting command for the shifting-up (shifting-down) is not output as long as an operation completion of the shifting-up action (shifting-down action) is not detected (steps S3, S4, S6).SELECTED DRAWING: Figure 6

With such an arrangement, thermal oxidation conditions of main oxidation reaction of second state B, i.e., 2SiC+3O→ 2SiO(solid phase)+2CO (gas phase), are maintained continuously during thermal oxidation processing. Change of partial pressure of oxidizer of the oxidizable gas atmosphere during thermal oxidation is in a range of 1-10Pa. A change width of partial pressure of oxidizer of the oxidizable gas atmosphere from initial value Pto maximum value Pduring thermal oxidation satisfies P≤P≤100P.SELECTED DRAWING: Figure 2
