Abstract

An ECU executes a program including the steps of: when there is a downshift instruction of an automatic transmission (YES in S100) and a vehicle is in a driven state (YES in S102), outputting (S104) to a supply pump a control signal corresponding to a common rail instruction pressure; and when a predetermined time has elapsed from the downshift instruction (YES in S106), executing (S108) fuel injection control.

Description

technical field [0001] The present invention relates to a control apparatus for a vehicle equipped with a common rail type diesel engine and a stepped automatic transmission, and in particular, to the control of fuel pressure in a common rail in a downshift mode during deceleration. Background technique [0002] Generally, in a vehicle equipped with an internal combustion engine and an automatic transmission, a technique of increasing the engine output in a park downshift mode is known. [0003] For example, Japanese Patent Laid-Open No. 7-229432 discloses an engine control apparatus for a vehicle equipped with an automatic transmission, which is effective in increasing the Large engine output, thereby reducing shift shock and shift time. In the parking downshift mode of the automatic transmission, the engine control apparatus executes control to increase the amount of intake air drawn into the engine, and also executes control to cut fuel under prescribed conditions. The ...
