  • Drive force control system for hybrid vehicle
    Patent number: 10759410
    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.
