Control device

摘要

A control device for a vehicle. A shift assist control section executes shift assist control of increasing a rotational speed of an input-side rotating member of the speed change mechanism. A possibility determining section that determines whether or not the rotating electrical machine can output required input torque. A mode selecting section that selects one shift mode from a first shift mode and a second shift mode that is different from the first shift mode in at least one of a condition for starting the downshift and processing. A torque compensating section that, if it is determined that the rotating electrical machine cannot output the required input torque, compensates for a shortfall in the required input torque in the shift assist control by using at least one of output torque of the internal combustion engine and torque that is transferred by the shift engagement device according to the shift mode.

1. A control device for a vehicle drive device in which a rotating electrical machine and a speed change mechanism are provided in this order from an internal combustion engine side on a power transmission path connecting the internal combustion engine and wheels, and in which the speed change mechanism is capable of changing a speed ratio by controlling an engagement state of a shift engagement device included in the speed change mechanism, the control device comprising:
a shift assist control section that, in downshift in which the speed ratio is changed to a higher speed ratio, executes shift assist control of increasing a rotational speed of an input-side rotating member of the speed change mechanism by increasing torque of the rotating electrical machine which is transferred to the input-side rotating member; a possibility determining section that determines whether or not the rotating electrical machine can output required input torque for increasing the rotational speed of the input-side rotating member according to a predetermined target rotational speed change rate; a mode selecting section that selects one shift mode from a first shift mode and a second shift mode that is different from the first shift mode in at least one of a condition for starting the downshift and processing; and a torque compensating section that, if it is determined that the rotating electrical machine cannot output the required input torque, compensates for a shortfall in the required input torque in the shift assist control by using at least one of output torque of the internal combustion engine and torque that is transferred by the shift engagement device according to the shift mode.
