US 2026/0223769 A1 · SPEED-BASED IMPLEMENT COMMANDS ON A MOWING VEHICLE

Abstract

A speed-based raise/lower control system receives a path plan for use in navigating a grass mowing vehicle. A lookahead processor looks ahead by a lookahead distance to determine whether an implement control event (such as a raise event or a lower event) is to occur within the lookahead distance. A dynamic actuation point identifier calculates a location of an actuation point, where a command is to be issued to commence the implement control event, based upon a current speed of the mowing vehicle. The dynamic actuation point identifier continues to update the location of the actuation point based upon a current speed of the mowing vehicle until a location of the mowing vehicle is within a threshold distance of the location of the actuation point. An actuation control signal generator generates the actuation control command signal to commence the implement control event when the current position of the mowing vehicle is within the threshold distance of the location of the actuation point.

Dependent claims

A computer implemented method of controlling a mowing vehicle, comprising:

identifying an implement control event ahead of the mowing vehicle along a route of the mowing vehicle;
accessing an event latency value corresponding to the implement control event, the event latency value being indicative of a latency between when an event control command is issued to execute the implement control event and when the implement control event is completed;
detecting a speed of the mowing vehicle;
automatically computing, based on the detected speed of the mowing vehicle and an event latency value, a location of an actuation point along the route of the mowing vehicle at which to issue an event control command to execute the implement control event;
automatically computing whether to issue the event control command based on the location of the actuation point;
and
automatically repeating the steps of detecting the speed of the mowing vehicle, automatically computing the location of the actuation point, and automatically computing whether to issue the event control command until the event control command is issued.

4 more elements

A mowing vehicle, comprising:

a propulsion subsystem;
a steering subsystem;
a cutting head;
and
a mowing vehicle control system configured to dynamically identify an actuation point for issuing a cutting head position command, to change a position of the cutting head from a first position to a second position, based on a current ground speed of the mowing vehicle and based on a location where the cutting head is to be in the second position.
