Kiyosuke HAYAMIZU 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: 11906040
    Abstract: A shifting device in which a selected shift position can be confirmed easily, and which can be fitted easily in vehicles. The shifting device comprises: a restriction member that restricts a movement of a shift lever into a predetermined shift slot in a first shifting mode, and that cancels the restriction of the movement of the shift lever in a second shifting mode; and an indicator that indicates a first pattern when the first shifting mode is selected, and that indicates a second pattern when the second shifting mode is selected.
    Type: Grant

  • Publication number: 20230382238
    Abstract: A shifting device for an electric vehicle having a virtual manual transmission system, that is configured to realize a variety of shift patterns and torque characteristics. The shifting device comprises: an indicator that indicates a shift pattern; and an indication switcher that switches the shift pattern indicated in the indicator to another pattern. At least any one of the number of the shift positions and a virtual gear stage assigned to the shift position in the shift pattern switched by the indication switcher is different from that in the previous shift pattern indicated in the indicator before switched by the indication switcher.

  • Patent number: 11654779
    Abstract: A virtual manual transmission system for an electric vehicle for simulating the behavior of a vehicle having a manual transmission by controlling a motor while protecting an electric storage device. A controller is configured to: change torque of the motor when a virtual manual shifting is executed by operating a clutch device, an accelerator device, and a shifting device; and reduce a regulation on a change rate of the torque of the motor or an input/output power to/from the electric storage device.
