  • Publication number: 20240425035
    Abstract: There are provided: an input torque detection part configured to detect an input torque variation value; a first filter processing part configured to extract and obtain, from the input torque variation value, a post-first-filter variation value that varies with a specific variation period; a vibration reduction control part configured to calculate an opposite-phase torque variation value whose phase is opposite to a phase of the post-first-filter variation value, and execute vibration reduction processing; and a second filter processing part configured to extract and obtain, from the post-first-filter variation value, a post-second-filter variation value that varies with a period longer than the specific variation period. The vibration reduction control part is configured to cause the vibration reduction processing to be brought into a non-execution state based on the post-second-filter variation value.

  • Patent number: 11597372
    Abstract: A vehicle vibration control device includes: a motor generator connected via a motor shaft to a power transmission path between a crankshaft of an engine and a drive axle that transmits a drive torque to a tire; and a motor generator control portion executing control of an output torque which is actually output by the motor generator. The motor generator control portion includes a damper torque calculation section that acquires information on a crank angle and a motor angle to calculate a damper torque generated by a damper, an explosion cycle calculation section, a reverse phase torque calculation section, a delay time calculation section, a compensation time calculation section, a first compensation time calculation section, a torque correction amount calculation section, and a command output section.

  • Patent number: 5932866
    Abstract: An optical card (100) with a built-in IC module comprises a base card (101), an optical recording part (11) incorporated into the base card (101), and an IC module (120) mounted on the base card (101). The IC module (120) has a base (122), an IC chip unit (121) mounted on one of the surfaces of the base (122), and a terminal part (123) formed on the other surface of the base (122). The terminal part (123) is disposed in a region corresponding to the optical recording part (110) so as to be exposed to view. The IC chip unit (121) is disposed outside the region corresponding to the optical recording part (110).
