    摘要: A control system configured with a speed change mechanism. When starting combustion in an internal combustion engine under a combustion-stopped vehicle running condition, the combustion in the internal combustion engine is stopped, the speed change mechanism forms the one-way transmission speed, and the output member rotates. A rotational speed feedback control is executed that sets a value that multiplies a rotational speed of the output member by a speed ratio of the one-way transmission speed as a reference rotational speed of the input member, sets a starting rotational speed, and controls a rotary electric machine such that the rotational speed of the input member matches the target rotational speed. During execution of the rotational speed feedback control, a start control is performed that increases engagement pressure of the clutch to increase a rotational speed of the internal combustion engine and start combustion in the internal combustion engine.

    摘要: A control device controlling a hybrid vehicle drive apparatus that includes an internal combustion engine, a rotary electric machine drivingly connected to a wheel and a clutch selectively drivingly connecting the internal combustion engine with the rotary electric machine. The control device performs control such that, when a start request of the internal combustion engine is issued in the state in which the clutch is released and combustion of the internal combustion engine is stopped, a rotational speed of the internal combustion engine is raised to a rotational speed of the rotary electric machine by transmitting driving torque of the rotary electric machine to the internal combustion engine by increasing a torque transfer capacity of the clutch, and, after the rotational speed of the internal combustion engine is synchronized with the rotational speed of the rotary electric machine, the combustion of the internal combustion engine is started.
