Kosuke TAKEGAWA 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: 9908409
    Abstract: The present invention provides a vehicle accelerator pedal reaction force control device which may increase an output by a small accelerator opening operation, allows the driving force etc. to be easily controlled by the driver's intention, increases the resistance to the depression of an accelerator to make the driver feel secure, and allows the driver to experience the operational feeling that he or she is operating the vehicle by himself or herself. The vehicle accelerator pedal reaction force control device 1 has a first mode in which a relation of the driving force with respect to an accelerator opening is regarded as a predetermined characteristic and a second mode in which the driving force is higher than the driving force in the first mode. In the second mode, the pedal reaction force increases with an increase in the accelerator opening with respect to the first mode.

  • Patent number: 9695747
    Abstract: A vehicle engine speed display device is provided with an engine speed detection unit which detects an engine speed, an engine speed display unit which displays an engine speed, and a display control unit which controls the engine speed display unit on the basis of the detected engine speed. The display control unit determines whether a phase of a gear shift operation is an inertia phase when gear shift control of an automatic transmission is executed, and sets display responsiveness of a tachometer with respect to the detected engine speed higher than display responsiveness to be set when the phase is not the inertia phase, when the phase of the gear shift operation is determined to be the inertia phase.

  • Patent number: 8886420
    Abstract: A control method for an automatic transmission includes a step of canceling the shift performed by a shift operation for performing shifting in the same direction as that of the shifting performed by automatic shift control, when the shift operation is performed before the input revolution speed correlation value of the automatic transmission becomes a predetermined value, after the automatic shift control has been started in a manual shift mode, a step of switching a shift stage display at a timing at which the shift operation that is to be canceled has been performed, and a step of switching the shift stage display at a timing at which the input revolution speed correlation value becomes the predetermined value when a shift operation is not performed within a period of time from when the automatic shift control is started till when the input revolution speed correlation value becomes the predetermined value.
