  • Publication number: 20220094292
    Abstract: The degree of flexibility of a speed curve for a target rotational speed of a motor is to be increased. A motor control circuit 11 measures a duty cycle of an input speed command signal Sc indicating a target rotational speed of a motor 50 to be driven, sets an inflection point In for each duty cycle obtained by equally dividing a possible duty cycle range assumed by the speed command signal Sc based on resolution information 301 indicating a resolution of the duty cycle of the speed command signal Sc, calculates a rotational speed corresponding to the measured duty cycle of the speed command signal Sc based on rotational speed information 302 indicating rotational speeds at the inflection points In on a speed curve and the set inflection points In, and determines the calculated rotational speed as the target rotational speed.

  • Publication number: 20220089013
    Abstract: An apparatus including a transmission mechanism in a power transfer path between a drive source and wheels; an oil pressure control device supplying lubricating oil to the transmission mechanism; and a control part outputting an electrical instruction to increase a flow rate of the supplied lubricating. When the control part outputs an electrical instruction to the oil pressure control device to increase a flow rate of lubricating oil supplied to the transmission mechanism, and determines that the flow rate of lubricating oil supplied to the transmission mechanism from the oil pressure control device does not increase as indicated by the electrical instruction (time t1), the control part considers that the oil pressure control device is in an abnormal state, and can impose a limitation that an absolute value of torque of the transmission mechanism transferred between the wheels and the drive source be reduced (time t1-t5).
