Abstract
A control device for a vehicle drive device in a vehicle having a power source including an engine and a stepped automatic shifting portion making up a part of a power transmission path between the power source and a drive wheel, the control device providing input torque limiting control if a downshift of the automatic shifting portion is executed during an accelerator depressing operation, to limit an input torque to the automatic shifting portion before initiation of an inertia phase in the downshift as compared to the case of not executing the downshift, wherein in the input torque limiting control, if an accelerator variation before the start of the downshift is equal to or less than a predetermined accelerator variation limit, the control device limits the input torque before the initiation of the inertia phase to the input torque at the time of a shifting output commanding the execution of the downshift, and wherein if an accelerator variation before the start of the downshift is greater than the accelerator variation limit, the control device limits the input torque before the initiation of the inertia phase equal to or less than a predetermined input torque limit value larger than the input torque at the time of the shifting output.

10. A control device for a vehicle drive device in a vehicle having a power source including an engine and a stepped automatic shifting portion making up a part of a power transmission path between the power source and a drive wheel, the control device providing input torque limiting control if a downshift of the automatic shifting portion is executed during an accelerator depressing operation, to limit an input torque to the automatic shifting portion before initiation of an inertia phase in the downshift as compared to the case of not executing the downshift, wherein
in the input torque limiting control, if an accelerator variation before the start of the downshift is equal to or less than a predetermined accelerator variation limit, the control device limits the input torque before the initiation of the inertia phase to the input torque at the time of a shifting output commanding the execution of the downshift, and wherein if an accelerator variation before the start of the downshift is greater than the accelerator variation limit, the control device limits the input torque before the initiation of the inertia phase equal to or less than a predetermined input torque limit value larger than the input torque at the time of the shifting output.
