Abstract
A hybrid vehicle includes an electric steplessly speed changing unit, an engaging device, and an electronic control unit. The electric steplessly speed changing unit includes a differential mechanism including a first rotary element to which an engine is coupled, a second rotary element to which a first rotary machine is coupled, and a third rotary element as an output rotary member of the differential mechanism to which a second rotary machine is coupled. Differential operation of the electric steplessly speed changing unit is controlled by controlling operation of the first rotary machine. The engaging device is provided in a power transmission path between the third rotary element and drive wheels. In control of the hybrid vehicle, when at least one of the first rotary machine and the second rotary machine is operated with a predetermined positive or negative maximum torque, the electronic control unit controls a slip amount of the engaging device by changing the torque capacity of the engaging device.
