A control system for a hybrid vehicle configured to avoid a sudden and significant reduction in a drive torque generated by a motor during high load operation. A controller comprises a determiner that determines a satisfaction of a predetermined condition, and a power limiter that restricts an upper limit of an output power of an electric storage device supplied to the motor upon satisfaction of the predetermined condition, to a restricted upper limit value which is smaller than a normal upper limit value set in a case that the predetermined condition is not satisfied.

A vehicle includes an engine, an electric motor, an electrical storage device and a controller. The electric motor generates electric power by using driving force of the engine. The controller controls supply of electric power, which is at least one of electric power generated by the electric motor or electric power stored in the electrical storage device, to an outside of the vehicle. The controller selects, on the basis of setting made by a user, whether to permit or prohibit generation of electric power by using the driving force of the engine.

A control system for a hybrid vehicle configured to prevent a reduction in the purifying performance of the catalyst in a predetermined operating mode. An operating mode of the hybrid vehicle can be selected from a first hybrid vehicle mode, a second hybrid vehicle mode, and a fixed mode. A controller that is configured to restrict a shifting operation between the first hybrid vehicle mode and the second hybrid vehicle mode via the fixed mode, when the purifying device is being warmed or the purifying device has to be warmed.

An engine clutch control apparatus of a hybrid vehicle is provided. The apparatus includes an engine clutch that is disposed between an engine and a drive motor to selectively connect the engine and the drive motor and an integrated starter-generator that is connected with the engine to start the engine or to generate electricity. A vehicle controller releases or couples the engine clutch to implement a driving mode and determines a chargeable torque and an engine target estimation torque based on a generator rotation speed of the integrated starter-generator. An engine target torque and a charge torque are set based on the chargeable torque and a clutch input torque is generated using at least one of the engine target torque, an engine friction torque, and the charge torque. The engine clutch is then released when the clutch input torque is less than a reference value.
