Title:
車両用駆動装置の制御装置
Document Type and Number:
Japanese Patent JP5783058
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of a vehicular drive device that can make the actual engine rotation speed to follow appropriately a target engine rotation speed under changing the speed of an automatic transmission.SOLUTION: When an automatic transmission 18 changes the speed, even if power transmitted in the electric route is changed according to progress of the speed change, engine speed Ne cannot be controlled according to the target, since there is a delay in fluid transmission of a torque converter 16. When the automatic transmission 18 changes the speed, the delay in fluid transmission can be supplemented by delaying the change of the power transmitted in the electricity route more than when changing according to the progress of the speed change of the automatic transmission 18 (precisely, delaying change of the power transmitted in the electric route to the progress of the speed change), the actual engine rotation speed Ne can be made appropriately follow the target engine rotation speed Ne* of the automatic transmission 18 under changing the speed.
