Abstract: A hybrid vehicle includes a multi-mode power system. The power system includes a battery, an electrical power input, a first motor/generator, a second motor/generator, and a clutch. A first operating mode is defined by deactivation of the internal combustion engine and the operation of the vehicle by electrical force provided from the battery to the second motor/generator. In a second operating mode, activation of the internal combustion engine generates electrical power by providing rotational force to the first motor/generator. In a third operating mode, engagement of the clutch couples the internal combustion engine and the second motor/generator to provide rotational force to the wheels. In a fourth operating mode, engagement of the clutch couples the internal combustion engine with the second motor/generator, and the first motor/generator further provides rotational force to the wheels.

Abstract: A method for checking an out-of-step of a synchronous motor includes detecting three-phase currents of the synchronous motor; determining whether a relationship between the three-phase currents satisfies a preset requirement; and if no, determining that the synchronous motor is out of step. It is determined that the synchronous motor is out of step when amplitudes of each current of the three-phase currents are not equal or when the phase difference between the three-phase currents is not 120°.
