1. A control system for controlling an agricultural machine, comprising:
- a rate of change identifier component that receives a force sensor signal from a force sensor on a machine, the received force sensor signal being indicative of a sensed variable force imparted by the machine, and wherein the rate of change identifier component is configured to identify a rate of change of the sensed variable force, wherein the rate of change is identified based on a first received force sensor signal received at a first time and a second received force sensor signal received at a second time, wherein the second time is different from the first time, and the rate of change is based on a difference between the first and second received force sensor signals; and
a control signal generator component that generates a set of control signals that control a subsystem on the agricultural machine, wherein the set of control signals is generated based on the identified rate of change of the sensed variable force.

Abstract
A variable is sensed that is indicative of a performance of a machine. A rate of change of the sensed variable is determined, and a control signal is generated for controlling an agricultural vehicle, based upon the rate of change in the value of the sensed variable.

15. A computer implemented method of controlling a towing vehicle that tows a planting machine, the method comprising:
-
receiving an acceleration sensor signal indicative of a sensed acceleration of a portion of the planting machine from an acceleration sensor; identifying a rate of change of the sensed acceleration based on a first received acceleration sensor signal received from the acceleration sensor at a first time and a second received acceleration sensor signal received from the acceleration sensor at a second time, wherein the second time is different from the first time, and the rate of change is based on a difference between the first and second received acceleration sensor signals; generating a set of control signals based on the identified rate of change of the sensed acceleration; and controlling a subsystem on the towing vehicle based on the set of control signals. - View Dependent Claims (16, 17, 18)

19. An agricultural machine, comprising:
-
a propulsion system that drives the agricultural machine at a controllable travel speed; and a control system comprising; a rate of change identifier component that receives a seed spacing sensor signal from a seed sensor, the received seed spacing sensor signal being indicative of a sensed seed spacing, and wherein the rate of change identifier component is configured to identify a rate of change of the sensed seed spacing based on a first received seed spacing sensor signal received from the seed sensor at a first time and a second received seed spacing sensor signal received from the seed sensor at a second time, wherein the second time is different from the first time, and the rate of change is based on a difference between the first and second received seed spacing sensor signals; and a control signal generator component configured to, based on the identified rate of change of the sensed seed spacing, generate a speed control signal that controls the propulsion system to control travel speed of the agricultural machine, such that the travel speed is, at least in part, based on the identified rate of change of the sensed seed spacing. - View Dependent Claims (20)
