Publication number: 20200408818Abstract: A load estimating device measures a voltage and a current supplied to a load connected with a generator, calculates a feature amount of the load, senses a remaining amount of fuel, outputs a time during which the load is continuously operable. The device estimates what the load connected with the generator is, based on the calculated feature amount and the feature amounts stored in a storage, and determines the time during which the estimated load is continuously operable, based on a power consumption of the estimated load, and the remaining amount of fuel. The device has a load registration mode for causing the storage to store therein a feature amount of a new load that is not stored in a storage.Type: ApplicationFiled: September 11, 2020Publication date: December 31, 2020Applicant: HONDA MOTOR CO., LTD.Inventors: Ryo Oshima, Nobuyuki Sasaki, Mitsuhiro Ito, Mio Oshima, Yoshihiro Matsunaga, Sho Takada

Publication number: 20200408819Abstract: An oscillatory electric signal having an oscillation frequency is processed by time-sampling to generate a sampled oscillatory electric signal. A nonlinear circuit driven by the sampled oscillatory electric signal outputs a hysteretic response signal as a function of the sampled oscillatory electric signal. The hysteretic response signal has a frequency in a first frequency range as a result of an increase in the oscillation frequency of the oscillatory electric signal, and a frequency in a second frequency range as a result of a decrease in the oscillation frequency of the oscillatory electric signal. A detection circuit processes the hysteretic response signal to compute an envelope signal of the hysteretic response signal, perform a comparison of the envelope signal with a threshold, and produce a signal indicative of an increase or a decrease in the oscillation frequency of the oscillatory electric signal as a result of the outcome of the comparison.Type: ApplicationFiled: June 22, 2020Publication date: December 31, 2020Applicant: STMicroelectronics S.r.l.Inventors: Marco Maria BRANCIFORTE, Luigi FORTUNA, Arturo BUSCARINO, Maide BUCOLO, Fernando Nuwan PORUTHOTAGE
