Title:
DRIVE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/181409
Kind Code:
A1
Abstract:
When a torque requested to be transmitted from a rotary electric machine (MG) side to an automatic transmission (TM) via an engaging device (CL1) that interrupts/connects power transmission between the rotary electric machine (MG) and the automatic transmission (TM) is represented by a requested torque (Tr), a control device (10) is configured to execute: torque response slip control for bringing the engaging device (CL1) into a slip-engaged state so that a transmission torque (T) of the engaging device (CL1) has a magnitude corresponding to the requested torque (Tr); gear change control for switching gears of the automatic transmission (TM); and transmission torque limiting control for limiting the transmission torque (T) of the engaging device (CL1) to a level equal to or lower than a limiting value (LM) that is smaller than the requested torque (Tr). When the torque response slip control is in execution in the case of executing the gear change control, the control device executes the transmission torque limiting control instead of the torque response slip control.
