Patent number: 6098003Abstract: A control apparatus and method for an automatic transmission that prevents incorrect determination of the start of a gear change inertia phase caused by bounding of an input shaft speed, and that prevents delay of the detection of the start of the inertia phase. A working fluid pressure of the frictional element is feedback-controlled in an inertia phase of a gear change transition of a speed-changing gear mechanism, wherein the input shaft speed of the mechanism changes along with an engaging operation of a frictional element of the mechanism. When it is determined that a starting point for the inertia phase control has been reached, inertia phase control is initiated. After a predetermined determination interval subsequently elapses, it is determined whether the inertia phase control should continue.Type: GrantFiled: October 15, 1998Date of Patent: August 1, 2000Assignee: Denso CorporationInventors: Tetsuji Kozaki, Hiroshi Enomoto

Patent number: 5329895Abstract: An intake valve or an exhaust valve is lifted through a swingable cam by the rotation of a rotatable cam formed in the cam shaft. A surface at which the swingable cam abuts with the rotatable cam is tapered in the axial direction in which said cam shaft extends, and the valve shift timing is changed by transferring the cam shaft, that is, the rotatable cam in the axial direction in which said cam shaft extends. The power transmitting member such as a helical gear to be rotated with the output shaft of the engine is engaged with the cam shaft through a helical spline. The power transmitting member is so arranged as to be unmovable in the axial direction in which said cam shaft extends. The rotational phase of the rotatable cam relative to the output shaft of the engine is changed by displacement of the cam shaft relative to the power transmitting member in the axial direction in which said cam shaft extends.Type: GrantFiled: September 27, 1993Date of Patent: July 19, 1994Assignee: Mazda Motor CorporationInventors: Masami Nishida, Toru Kurisu, Takashi Ikai, Hiroaki Sugiura, Hiroshi Enomoto, Masunori Kanda, Eiichi Yanagida, Hiroaki Deguchi, Masaki Fukuma, Akira Asai
