  • Patent number: 12246562
    Abstract: An estimation apparatus includes a rotation speed acquisition unit, a driving force acquisition unit, a slip ratio calculation unit, a slope calculation unit, and an estimation unit. The rotation speed acquisition unit sequentially acquires rotation speeds of the tires. The driving force acquisition unit sequentially acquires a driving force of the vehicle. The slip ratio calculation unit calculates a slip ratio based on the sequentially-acquired rotation speeds of the tires. The slope calculation unit calculates the slope of the slip ratio with respect to the driving force based on a large number of data sets of the slip ratio and the driving force, as a regression coefficient representing a linear relationship between the slip ratio and the driving force. The estimation unit estimates the wear state of the tires based on the slope.

  • Publication number: 20240286484
    Abstract: An acceleration device can prevent abnormal acceleration of a vehicle even when an accelerator pedal is erroneously abnormally stepped on instead of a brake pedal, and alert a driver of occurrence of erroneously stepping on the accelerator pedal. Assuming that a driver erroneously steps on an accelerator pedal hard instead of a brake pedal, a magnet of a fixation part of a transmission/blocking mechanism and a magnetic opposing surface of a movable part are disengaged and separated from each other. Accordingly, movement of the accelerator pedal with respect to an accelerator lever is blocked, and the accelerator lever is returned to an idling state due to the action of the accelerator mechanism. Also, an impact and sound of the disengagement of the magnet is transmitted to the driver, and the foot takes a position different from a normal position. Accordingly, the driver can notice erroneous stepping on the accelerator pedal.
