    摘要: Spectrum access for Internet of things (IOT) applications including receiving information about expected use by a primary user of a spectrum band in a radio frequency spectrum. The spectrum band is classified into at least two working modes based on the expected use. The spectrum band is sensed to determine a current access pattern of the primary user. Based on the classifying and the sensing, one of the working modes is selected as a current working mode of the primary user. Transmissions are scheduled on the spectrum band using a current schedule that is responsive to the current working mode of the primary user. If the current working mode of the primary user changes, the sensing, selecting, scheduling, and determining whether the current working mode has changed are re-performed. Otherwise, the transmission scheduling and determining if the current working mode has changed are re-performed.

    摘要: A hybrid vehicle and method of control are associated with the following operation. A quantized previous engine power command based on a previous engine power command is obtained. A current engine power command is quantized. The quantized current engine power command is maintained if the magnitude of the difference between the current engine power command and the quantized previous engine power command is larger than a threshold. The quantized current engine power command is set equal to the quantized previous engine power command if the magnitude of the difference between the current engine power command and the quantized previous engine power command is smaller than the threshold. An output engine power command based on the quantized current engine power command is generated. An engine of the hybrid vehicle is operated based on the output engine power command.

    摘要: A method and system for limiting a fast transient in an engine in a hybrid vehicle is provided. The predicted fuel loss percentage is calculated from an inferred air-fuel ratio (inferred lambda). The rate limit term is calculated from a measured air-fuel ratio (measured lambda) and an engine torque command change rate. The predicted fuel loss percentage and the rate limit term are inputs into a calibration table to determine an engine power rate limit and an engine torque rate limit. An engine torque command is limited using the engine torque rate limit to control a fast engine torque transient for an engine. An engine power command is limited using the engine power rate limit to control the fast engine power transient for the engine.
