Kazuki KAWAMOTO 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: 11679772
    Abstract: A drive control system is provided, which is mounted on a vehicle configured to travel by operation of a driver. The drive control system includes an actuator configured to output a driving force for the vehicle to travel, an output sensor configured to detect a driving force requested by the operation of the driver, and a control device configured to control operation of the actuator based on the requested driving force detected by the output sensor. The control device sets a target output value by adding a given delay time to a requested output value set corresponding to the requested driving force, and controls the actuator so as to output the target output value based on a response characteristic of the actuator.

  • Patent number: 11143118
    Abstract: To provide a control device for a vehicle capable of controlling the torque of a drive source so as to appropriately balance the suppression of body vibrations and the securing of a transient response during acceleration or deceleration. This control device for a vehicle includes an accelerator position sensor that detects the accelerator opening, a torque adjustment mechanism such as a throttle valve that adjusts the torque of an engine as the drive source of the vehicle, and a powertrain control module (PCM) that controls the torque adjustment mechanism based on the accelerator opening. The PCM sets the target acceleration of the vehicle based on the accelerator opening, sets the target torsion angle of the drive shaft based on the target acceleration, sets the target torque of the engine based on the target torsion, and controls the torque adjustment mechanism based on the target torque.

  • Patent number: 10626197
    Abstract: An object of the invention is to provide an EVOH which has improved melt moldability and is excellent in terms of gas barrier property and secondary formability. The present invention relates to an ethylene-vinyl alcohol copolymer that, when examined by liquid chromatography, gives an ethylene content distribution curve which has at least two peaks and in which the ethylene content (a) of a component that shows a highest peak (A), the ethylene content (b) of a component that shows a second highest peak (B), and the proportion (v) and distribution of component(s) (V) having ethylene contents (w) corresponding to specific regions (W) are within specific ranges.
