Control device for vehicle drive device

摘要

A control device limiting an input torque to an automatic shifting portion before initiation of an inertia phase in a downshift as compared to a case of not executing the downshift, wherein in an input torque limiting control, if an accelerator variation before a 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 a 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.

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