  • Patent number: 9463792
    Abstract: A method for monitoring a torque in a hybrid electric vehicle includes calculating an output torque of a motor based on a discharging power of a high voltage battery, a consumption power of a plurality of electric loads, and a motor speed. A first difference value between a motor torque command and the calculated output torque of the motor is calculated. The first difference value is compared with a first reference value. When the first difference value is larger than the first reference value, the hybrid electric vehicle is entered in a fail safe mode.

  • Publication number: 20160266008
    Abstract: An apparatus for estimating a crank angle when an engine stops includes a crank sensor generating an output signal indicating a rotational angle of a crankshaft. A resolver generates an output signal indicating a rotor absolute angular position of a motor which is connected to the engine to transmit power. A controller is configured to store output signal data of a crank sensor and output signal data of the resolver until the engine stops, and determines the crank angle based on motor reverse rotation information from the stored crank sensor output signal data and the stored resolver output signal data when the engine stops completely.
