Abstract
A trailering support device able to load a hull onto a trailer includes one or more controllers configured or programmed to acquire characteristic information indicating a relationship between a steering angle of the hull and a turning radius of the hull; acquire relative position information between the trailer and the hull; detect the steering angle of the hull; predict future movement of the hull based on the acquired characteristic information, the acquired relative position information, and the detected steering angle; generate a predicted trajectory; and provide notification of a positional relationship between the hull and the trailer and provide notification of the generated predicted trajectory.
Claims16
A trailering support device for loading a hull onto a trailer, the trailering support device comprising:
- one or more controllers configured or programmed to function as:
- a first acquisition unit to acquire characteristic information indicating a relationship between a steering angle of the hull and a turning radius of the hull;
- a second acquisition unit to acquire relative position information between the trailer and the hull;
- a detector to detect the steering angle of the hull;
- a generation unit to predict future movement of the hull based on the characteristic information acquired by the first acquisition unit and the steering angle detected by the detector, and to generate a predicted trajectory;
- and
- a control unit configured to, on a display, display an image showing a positional relationship between the hull and the trailer based on the relative position information acquired by the second acquisition unit, and display the predicted trajectory on the image in a superimposed manner so as for a vessel operator to operate a steering device so that the predicted trajectory passes through a trailer displayed on the image.
A trailering system comprising:
- a marine vessel including a hull;
- and
- a trailering support device to load the hull onto a trailer, the trailering support device including:
- one or more controllers configured or programmed to function as:
- a first acquisition unit to acquire characteristic information indicating a relationship between a steering angle of the hull and a turning radius of the hull;
- a second acquisition unit to acquire relative position information between the trailer and the hull;
- a detector to detect the steering angle of the hull;
- a generation unit to predict future movement of the hull based on the characteristic information acquired by the first acquisition unit and the steering angle detected by the detector, and to generate a predicted trajectory;
- and
- a control unit configured to, on a display, display an image showing a positional relationship between the hull and the trailer based on the relative position information acquired by the second acquisition unit, and display the predicted trajectory on the image in a superimposed manner so as for a vessel operator to operate a steering device so that the predicted trajectory passes through a trailer displayed on the image.
A trailering support method for loading a hull onto a trailer, the trailering support method executable by a computer and comprising:
- acquiring characteristic information indicating a relationship between a steering angle of the hull and a turning radius of the hull;
- acquiring relative position information between the trailer and the hull;
- detecting the steering angle of the hull;
- predicting future movement of the hull based on the acquired characteristic information and the detected steering angle, and generating a predicted trajectory;
- and
- displaying, on a display, an image showing a positional relationship between the hull and the trailer based on the relative position information acquired by the second acquisition unit, and display the predicted trajectory on the image in a superimposed manner so as for a vessel operator to operate a steering device so that the predicted trajectory passes through a trailer displayed on the image.
