Provided is a control device which, when switching gears in a transmission, is capable of outputting torque to vary the rotational speed of an input member, by both an electric motor and an internal combustion engine. The control device for controlling the drive devices of an automobile is provided with: an input member that is drive-coupled to a drive source having an electric motor and an internal combustion engine; an output member that is drive-coupled to wheels; a transmission mechanism that varies and transmits the rotational speed of the input member to the output member, according to the gear ratio of the selected gear. When switching gears, a torque command value to change rotational speed is calculated, said value being the command value for torque to be output to the drive source in order to vary the rotational speed of the input member, and if the absolute value of the torque to be output by the electric motor is deemed to exceed a predetermined threshold, torque is outputted according to the torque command value to change rotational speed by both the electric motor and the internal combustion engine.
Description
technical field [0001] The present invention relates to a control device for controlling a vehicle drive device comprising: an input member drivably coupled to a driving force source having a rotary electric machine and an internal combustion engine; an output member drivably coupled to wheels; and a transmission mechanism, The rotational speed of the input member is shifted and transmitted to the output member according to the gear ratio of the selected gear speed among the plurality of switchable gear speeds. Background technique [0002] As a drive device for a hybrid vehicle including an internal combustion engine and a rotary electric machine as driving power sources, for example, the device described in the following Patent Document 1 is known. The technology of Patent Document 1 is configured to change the rotational speed of the input member by using the rotary electric machine if the rotary electric machine can be made to output a torque for changing the rotational ...
