Embodiment Construction

[0031] In the following description and drawings, the present invention is described in detail with reference to an exemplary embodiment.

[0032] A first exemplary embodiment is described below.

[0033] FIG. 1 is a schematic diagram of a transverse type vehicle drive device used in a FF (Front Engine-Front Drive) vehicle. In this driving device, the output of an engine 10 composed of an internal combustion engine such as a gasoline engine is transmitted to the drive wheels (front wheel). The torque converter 12 includes a pump wheel 20 connected to the crankshaft 18 of the engine 10, a turbine 24 connected to the input shaft 22 of the automatic transmission 14, and a one-way clutch 26 fixed on a shell as a non-rotating part. A stator 30 on body 28 and a lock-up clutch 32 directly connect crankshaft 18 to input shaft 22 via a snubber (not shown). A mechanical oil pump 21 such as a gear pump is connected to the pump wheel 20 . The oil pump 21 is driven by the engine 10 tog...

Abstract

An apparatus for controlling ignition timing during a shift in a vehicular automatic transmission is provided that is capable of suppressing shift shock in the event that input torque of the automatic transmission is affected by external changes, such as changes in fuel and air pressure and the like, by adjusting immediately to those changes. This control apparatus is provided with an ignition timing controller that controls an ignition timing retard amount; a calculator that calculates a basic retard amount; a detector that detects an engine retard amount; a determinator that determines a retard correction value based on a shift mode of the automatic transmission and the like; and a corrector that corrects the ignition timing retard amount of the controller based on the retard correction value, the basic retard amount, and the engine retard amount.

Description

[0001] The disclosure of Japanese Patent Application No. 2002-284260 filed on September 27, 2002, including its specification, specification drawings and abstract, is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to an apparatus and method for controlling ignition timing when shifting gears of an automatic transmission of a vehicle for temporarily reducing an input torque of the automatic transmission by a required retard amount when shifting gears of the automatic transmission. Background technique [0003] There is known an apparatus for controlling the ignition timing when shifting gears of an automatic transmission of a vehicle, the apparatus being equipped with a torque down controller which i) determines a temporary reduction of the slave device on the basis of an estimated input torque value of the automatic transmission and a vehicle speed. a required delay amount of the engine input torque to the automatic tr...
