Title:
CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2018132152
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the stagnation of a gear change caused by the lack of a rise amount of engine torque when performing a downshift in deceleration traveling accompanied by accelerator-off by using a gear change model.SOLUTION: At a downshift in deceleration traveling accompanied by accelerator-off which is performed by using a gear change model, since target AT output torque Totgt is set so as to be reduced toward AT output torque To after performing the downshift after the target AT output torque is increased within a range in which the target AT output torque reaches zero or smaller, a rise amount of engine torque Te at a rise of the engine torque Te becomes easy to be secured in a state that a release-side engagement device is released by increase of required engine torque Tedem in accordance with a temporary increase of the target AT output torque Totgt. Therefore, when performing the downshift in the deceleration traveling accompanied by the accelerator-off by using the gear change model, the stagnation of a gear change caused by the lack of the rise amount of the engine torque Te can be suppressed.SELECTED DRAWING: Figure 4
