Abstract: A control system for hybrid vehicles to prevent a reduction in a brake force when an electrical input to a battery is restricted. A controller is configured to execute a regeneration control to deliver a regenerative torque resulting from operating second motor as a generator to the drive wheels, and an engine brake control to deliver a brake torque resulting from a power loss of an engine to the output member. The controller is further configured to select an HV-Lo mode when an input power allowed to accumulate in the battery is smaller than a threshold 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.

Abstract: A hybrid vehicle includes a transmission unit and a clutch. The transmission unit is configured to be able to switch into a neutral state. The hybrid vehicle is able to transmit power of an engine through any one of a first path through which power is transmitted to a first MG from the engine via the transmission unit and a differential unit and another second path through which power is transmitted from the engine. The clutch is provided in the second path. The clutch switches between an engaged state where power is transmitted and a released state where transmission of power is interrupted. The controller sets the transmission unit to the neutral state and sets the clutch to the engaged state, and then starts the engine by increasing the rotation speed of the engine with the use of the first MG.

Abstract: A transmission unit is able to switch between a non-neutral state where power of an engine is transmitted via a path K1 and a neutral state where power of the engine is not transmitted via the path K1. A clutch is able to switch between an engaged state where power is transmitted from the engine to a first MG and a released state where transmission of power from the engine to the first MG is interrupted. When the transmission unit is controlled to the non-neutral state and, at the same time, the clutch is set to the released state, a vehicle is operable in series-parallel mode. When power is transmitted via the path K2 by directly coupling the engine to the first MG by the clutch and the path K1 is interrupted by controlling the transmission unit to the neutral state, the vehicle is operable in series mode.

Abstract: A hybrid vehicle includes a power transmission unit configured to switch a power transmission path between an engine, a first MG, and a second MG. The control device is configured such that, during execution of regenerative braking using at least one of the first MG and the second MG while the engine is stopped, when a state amount indicating a state related to a battery has reached a determination threshold, the control device executes a standby operation in which the state of the power transmission unit is brought from a current state closer to a state that enables an engine brake operation in which the engine in a fuel-cut state is rotated using an external force to generate a loss.
