Title:
CONTROL DEVICE FOR POWER TRAIN
Document Type and Number:
Japanese Patent JPH06219188
Kind Code:
A
Abstract:

PURPOSE: To improve accelerated response to accelerator pedal operations by performing predictive control of an engine and a power train based on the depressing speed.

CONSTITUTION: An A/T 11 and a lock-up clutch 9 for transmitting the power from an engine 7 to tires are provided. The maximum depressing speed of an accelerator pedal in the midst of depressing operation in the range of specified period of time from starting of the depressing operation of the accelerator pedal, is detected by an accelerator sensor 20 and a depressing speed calculation unit 22. Based on the detected depressing speed, a maximum accelerator pedal opening to be finally gained by the depressing operation is predicted by a maximum accelerator pedal opening prediction unit 4. On the basis of the predicted, maximum accelerator pedal opening, the control timing set by a speed change- lock up control unit 13 is changed to an earlier timing than a proper timing by a control timing changing unit. It is also possible to advance the control timing of supercharging-switching of a supercharger or the control timing of correction of the amount of increased fuel at the time of high loading.
