  "textContent": "Even when a failure has occurred in which a flow channel control valve that can switch a destination of oil discharged from a pump to an oil passage for lubrication and cooling or an oil passage for engagement control is fixed to a side where the oil passage for lubrication and cooling is connected to the pump, oil is appropriately supplied to the oil passage for engagement control. A vehicle drive device includes an engagement pressure flow channel (21), a lubrication flow channel (22), a first pump (1) having a discharge port connected to the engagement pressure flow channel (21), a second pump (2), and a flow channel control valve (5). The flow channel control valve (5) selectively switches flow channels between a first state in which an outflow destination of oil discharged from the second pump (2) is the engagement pressure flow channel (21) and a second state in which the outflow destination is the lubrication flow channel (22). When a failure in which the flow channel control valve (5) is fixed in the second state has occurred (#1), a control device (10) for a vehicle control device performs fail-safe control (#3) in which a rotational speed of at least one of an internal combustion engine (70) and a rotating electrical machine (80) is increased to supply oil to the engagement pressure flow channel (21) by the first pump (1).",
