Title:
CONTROL DEVICE FOR VEHICLE DRIVE SYSTEM
Document Type and Number:
Japanese Patent JPS6390449
Kind Code:
A
Abstract:
PURPOSE:To aim at ensuring precise responsiveness, by adding a feed-forward term during abnormal operation in which the difference between a desired intake-air pipe pressure and an actually measured intake-air pipe pressure is greater than a predetermined value and to forth, in order that feed-back control is made to the opening degree of a throttle valve in accordance with the desired intake-air pipe pressure depending upon a desired torque. CONSTITUTION:A control circuit 60 carries out the map computation of a desired torque in accordance with a desired horse power and an actually measured rotational speed by an input shaft rotational speed sensor 78. Then, map computation is made to a desired intake-air pipe pressure in accordance with an actually measured engine rotational speed NE by an engine rotational speed sensor 76 and the desired torque. Further, the pressure differential P between the desired intake-air pipe pressure and an actually measured intake-air pipe pressure by a pressure sensor 72 is obtained to compute a desire feed-back amount DELTAtheta of the throttle valve opening degree. In this arrangement, during abnormal operation in such a condition that the pressure differential DELTAP exceeds a predetermined value and to forth, a feed-forward term is computed so that a precise throttle valve opening degree signal is computed in accordance with the feed-back amount DELTAtheta and the above-mentioned feed-forward term, and is delivered to an actuator.
