When a wheel slips in a first mode in which an engine and the wheel are rotated at a predetermined ratio, an operating mode is shifted to a second mode in which a torque transmission between the engine and the wheel is interrupted and the vehicle is propelled by torque of driving machine connected to the wheel, or to a third mode in which the vehicle is propelled by delivering torque of the engine to the wheel while establishing a reaction torque by a predetermined rotary member.

Abstract: During a hybrid drive, a hybrid vehicle sets an engine required power based on a driving required power and controls an engine to output the engine required power, while controlling a motor to drive the hybrid vehicle with the driving required power. When a catalyst temperature of an exhaust emission control device is equal to or lower than a predetermined temperature that requires warming up, in the state that an output upper limit power which a power storage device is allowed to output is equal to or larger than a predetermined power, the hybrid vehicle sets a power calculated by subtracting the output upper limit power from the driving required power, to the engine required power. In the state that the output upper limit power is smaller than the predetermined power, the hybrid vehicle sets the driving required power to the engine required power.

Abstract: A control system for hybrid vehicles to prevent a reduction in a drive force when an output power of a battery is restricted. A first motor translates an output power of the engine partially into an electric power. A transmission mechanism distributes an output torque of the engine to the first rotary machine side and an output member side. A second motor is operated by one of the electric power translated by the first rotary machine and an electric power accumulated in the battery to generate a power. An operating mode can be selected from a first mode in which the output torque of the engine is delivered to the output member side at a first ratio, and a second mode in which the output torque of the engine is delivered to the output member side at a second ratio. The second ratio is smaller than the first ratio. A controller is configured to restrict selection of the first mode when an available output power of the battery to be supplied to the second rotary machine is smaller than a predetermined value.
