  • Patent number: 10934989
    Abstract: A vehicle control apparatus includes input-side and output-side rotating elements, a fuel injection controller, and an ignition timing controller. The ignition timing controller controls ignition timing of an engine to first timing on the condition that the engine is controlled from a fuel cut state to a fuel injection state, and afterwards, changes the ignition timing to second timing on advance side of the first timing. The ignition timing controller changes the ignition timing toward the second timing at a first change rate until a rotational acceleration rate of the output-side rotating element reaches a threshold. After the rotational acceleration rate of the output-side rotating element reaches the threshold, the ignition timing controller changes the ignition timing toward the second timing at a second change rate greater than the first change rate.

  • Patent number: 10935121
    Abstract: A strain wave gearing has a rigid internally toothed gear, a flexible externally toothed gear, and a sliding-contact type wave generator. The wave generator has: a plurality of gear pressing members that flexes the externally toothed gear in the radial direction at positions at equal angular intervals in the circumferential direction to form plurality of meshing portions which mesh with the internally toothed gear; and piezoelectric elements that generate ultrasonic vibration of 20 kHz to 80 kHz in the gear pressing members in the radial direction. Ultrasonic vibration is applied at contact sites where the gear pressing members and the externally toothed gear contact each other. As a result of a squeeze film effect, the apparent friction coefficient of each contact surface at the contact sites can be greatly reduced and rotational torque, of the wave generator can be reduced.
