Description

  The present invention relates to a travel information presentation device and a coaxial two-wheeled vehicle.

  Conventionally, in a navigation device that is mounted on a car and provides route guidance to a destination point, at an intersection or the like, the driver is notified of the distance to the turning point (distance to the intersection) and the turning direction by voice, or on the display. It was displayed.

  However, it is dangerous for the driver to see the display while driving the car. In addition, when the distance to the turning point and the turning direction are notified by voice, there is a problem that the driver is likely to misunderstand. This is because the driver may not be able to hear the voice under noise, or the information by voice notification may be insufficient.

Therefore, in Patent Document 1, an uneven shape output portion whose surface shape changes to unevenness is provided at the center of the handle of the automobile, and the driver is notified of the direction of bending due to the uneven shape of the uneven shape output portion. There is described a navigation device that periodically changes the concavo-convex shape of the shape output unit and notifies the driver of the distance to a turning point depending on the length of the cycle. As a result, the driver can detect the distance to the turning point and the turning direction without looking at the display. In addition, the driver is less likely to misunderstand than voice notification.
Further, Patent Document 2 describes a navigation device that performs route guidance using a vibrating body provided on a handle.

  In recent years, the development of coaxial two-wheeled vehicles that ride with a person standing has been actively carried out. The coaxial two-wheeled vehicle is also required to notify the driver of the distance to the turning point and the turning direction, like the automobile.

JP 2004-340930 A Japanese Patent Laid-Open No. 03-112000

However, in the navigation device described in Patent Document 1, the driver must visually recognize the concavo-convex shape output unit during driving, which is problematic in safety. Further, in the navigation device described in Patent Document 1, the distance to the turning point is notified by the length of the change period of the concavo-convex shape of the concavo-convex shape output unit. Therefore, the number of times that the uneven shape output unit repeats expansion and contraction is large, and the uneven shape output unit is likely to deteriorate.
Moreover, in the case of the navigation apparatus described in Patent Document 2, there is a problem that it is difficult to distinguish from vibration caused by traveling.

  Accordingly, an object of the present invention is to provide a travel information presentation device and a coaxial two-wheeled vehicle that can safely and reliably present travel information to a driver.

  The travel information presentation device according to the present invention is a travel information presentation device provided in the travel device. The travel information presenting device is a portion that is gripped by a driver on a handle that is operated by the driver, and a grip portion that is formed so as to be inflated and contracted, and an inflating and contracting portion that expands and contracts the grip portion into a predetermined shape. A contraction control unit. And the said expansion / contraction control part shows the information regarding driving | running | working of the said traveling apparatus to a driver | operator by expanding / contracting the said holding part to a predetermined shape.

  In the travel information presentation device according to the present invention, the expansion / contraction control unit presents the travel information to the driver by expanding and contracting the handle gripping unit. Therefore, the driver can recognize the travel information without visually recognizing the display or the like. Therefore, the travel information presentation device according to the present invention can safely present travel information to the driver. In addition, the driver can recognize the traveling information only by grasping the steering wheel. Therefore, the travel information presentation device according to the present invention can present the travel information to the driver more reliably than the case where the travel information is presented by voice or vibration. That is, in the travel information presentation device according to the present invention, the travel information can be safely and reliably presented to the driver.

  A coaxial two-wheeled vehicle according to the present invention includes the travel information presentation device. Therefore, in the coaxial two-wheeled vehicle according to the present invention, traveling information can be safely and reliably presented to the driver.

Moreover, the right side grip part 43 and the left side grip part 44 are formed in the substantially cylindrical shape. The right and left hands of the driver grip the right grip portion 43 and the left grip portion 44 so as to wrap around the side surface of the cylinder.

FIG. 5 shows an example of a cross-sectional view of the left grip part 44. Since the right grip 43 has the same configuration as the left grip 44, the illustration and description thereof are omitted. Specifically, FIG. 5 is a cross-sectional view taken along line VV in FIG. As shown in FIG. 5, the left grip 44 includes a plurality of tubes 44A, 44B, and 44C. The number of tubes included in the right side blip 43 and the left side grip part 44 is not limited to that shown in FIG. 5 and can be any number.
Furthermore, the left grip 44 includes a gas supply unit 44D, a lateral expansion prevention guide 44E, a cover 44F, and the like.
