  • Publication number: 20220377376
    Abstract: A transform type is obtained for decoding the transform block of transform coefficients. A template for entropy-decoding values related to the transform coefficients is selected based on the transform type. The template indicates, for a to-be-coded value, positions of already coded values. A context for selecting a probability distribution for entropy decoding a current value of the values is determined using the template. The current value is entropy decoded from a compressed bitstream using the probability distribution.

  • Publication number: 20220294378
    Abstract: In a DC/DC converter, a voltage input from a power source is converted into a predetermined voltage, a harmonic component generated by a harmonic signal generator is superimposed on the converted voltage, and a result is output to the inverter as power to drive an electric motor. As a result, the electric motor can be driven by the signal on which the harmonic components are superimposed without being limited to the upper limit of the switching frequency of the inverter.

  • Publication number: 20220266700
    Abstract: A torque control of an in-vehicle motor is performed in consideration of a slip prevention control. Filtering processing is performed by a first filter processor on a high-order torque command value from a high-order device, and filtering processing is performed by a second filter processor on an angular velocity detected by an angular velocity detector. A driving torque command value to drive an electric motor is calculated based on filtering processing results. Each of the filter processors changes a time constant of the filtering processing according to a road surface friction coefficient as disturbance information.
