PURPOSE:To suppress a shock and noise, by detecting a shift-up and kick-down through a feed current to a hydraulic pressure control solenoid of a frictional engagement device to decrease supply fuel to an intake system. CONSTITUTION:A shift-up signal is generated when a speed change shift used as a function of a signal of a throttle valve opening sensor 29 is changed from a low to high shift, and a feed current to a solenoid 45 in a hydraulic control circuit is changed. A kick-down signal is generated when a throttle valve opening is increased to a high degree, and the feed current to the solenoid 45 is changed to change the speed change shift from a high to low shift. A final injection quantity Qf is decreased by these signals for a basic injection quantity Qb, however, a rate (k) of its decrease is in proportion to the throttle valve opening to obtain a velation of Qf=(1-k)Qb. In this way, engine torque is decreased, and input and output side torque of a frictional engagement device engaged after a shift-up or kick-down is balanced to suppress a shock and noise. |
