  • Patent number: 10479367
    Abstract: An apparatus for active vibration control of a hybrid electric vehicle including an engine and a motor is disclosed. The apparatus includes: a position sensor to detect position information of the engine or the motor; and a controller to select a reference angle signal based on a signal from the position sensor. The controller performs fast Fourier transform (FFT) analysis by generating a reference angle, extracts a vibration component of each frequency through the FFT analysis, generates a reference signal by performing inverse FFT, and performs active vibration control of each frequency by reflecting a basic amplitude ratio, an adjustable rate according to an engine load, and an engine torque to the reference signal.

    Abstract: Various examples are provided for cryogenic power extraction. In one example, among others, a system for cryogenic power extraction includes a heat exchanger that can heat a cryogenic working fluid using exhaust heat from a heat source, and a turbine that can generate power from the heated cryogenic working fluid. In another example, a method includes heating a cryogenic working fluid with waste heat from a heat source and driving a turbine with the heated cryogenic working fluid. Power produced by the turbine can be used drive a mechanical load and/or generate electricity for use by an electrical load. For example, waste heat from a combustion engine of a vehicle can be used to generate power for driving mechanical loads of the engine and/or to generate electricity for charging a battery of the vehicle.

  • Patent number: 10399554
    Abstract: A hybrid electric vehicle includes a combustion engine, and an electric machine and storage battery coupled to one or more controller(s) configured to respond to various signals from a driver and vehicle components. In response, such controller(s) enable an automatic or auto ICE start stop capability that is managed for optimal HEV lifecycle operation, and fuel economy and efficiency. The controller(s) automatically start and stop the ICE in response to one or more of a torque demand signal, a vehicle speed signal, a steering torque power signal, and a brake signal. The controller(s) inhibit automatic stop of ICE responsive to the steering torque power exceeding a stop threshold, and in contrast initiate or enable automatic start responsive to the steering torque power exceeding a start threshold. The start threshold is calibrated and adjusted to exceed the stop threshold by a stability factor that is predetermined and/or adjusted by the controller(s).
