Naoya Onozato has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10024294
    Abstract: When an accelerator opening degree becomes zero, a fuel cut-permission vehicle speed is set on the bases of a cooling water temperature. During a delay time, torque reduction has the characteristic of being dependent on cooling water temperature, and in an unwarmed state, a relatively large amount of air is supplied. The fuel cut-permission vehicle speed has the characteristic of taking a high value when an engine is not warmed up and cooling water temperature is low, in accordance with delay time air amount reduction control, which is performed in accordance with cooling water temperature. This reduces any shocks or odd feelings experienced by an occupant.
    Type: Grant

  • Patent number: 9534687
    Abstract: A vehicle control device has a controller configured to control a hydraulic pressure required for shifting of a sub-transmission based on an input torque to the sub-transmission during the coordinated shift, and to execute limitation processing in which, when an instruction to execute specific control causing fluctuation in the input torque to the sub-transmission during the coordinated shift is issued, execution of the specific control is prohibited or the specific control is executed by limiting a control amount.
