Abstract

A guidance vehicle guides a dog for a walk, and includes a leash attachment, a distance sensor, and an electronic control unit. The leash attachment is configured to attach a leash that connects the dog. The distance sensor is configured to detect a dog-to-vehicle distance being a distance between the dog and the guidance vehicle. The electronic control unit is configured to execute a travel control of the guidance vehicle. The electronic control unit includes, as one of modes of the travel control, a walk guidance mode that causes the guidance vehicle to automatically travel along a walk route while guiding the dog to walk. The walk guidance mode executed by the electronic control unit includes a basic walk mode that controls the dog-to-vehicle distance so as to maintain a constant distance when the dog is moving along the walk route.

First claim

What is claimed is:

1. A guidance vehicle that guides a dog for a walk, comprising:
a leash attachment configured to attach a leash that connects the dog;
a distance sensor configured to detect a dog-to-vehicle distance being a distance between the dog and the guidance vehicle;
a top plate having a riding surface configured for the dog to ride on;
a dog paw position sensor including one or more dog paw position detectors associated with one or more traveling directions of the guidance vehicle, and attached to a dog riding section of the riding surface; and
an electronic control unit configured to execute a travel control of the guidance vehicle, wherein
the electronic control unit includes, as one of a plurality of modes of the travel control, a walk guidance mode that causes the guidance vehicle to automatically travel along a walk route while guiding the dog to walk,
the walk guidance mode executed by the electronic control unit includes a basic walk mode that controls the dog-to-vehicle distance so as to maintain a constant distance when the dog is moving along the walk route, and
the electronic control unit includes a dog operation mode that controls travel of the guidance vehicle based on an input to the dog paw position sensor as one of the modes of the travel control.

2. The guidance vehicle according to claim 1 , wherein
the riding surface is configured for an owner of the dog to ride on,
the guidance vehicle further comprises an operation device configured for the owner to operate the guidance vehicle, and
when an input to the dog paw position sensor and an input to the operation device are simultaneously present during execution of the dog operation mode, the electronic control unit is configured to control the travel of the guidance vehicle based on the input to the operation device.
