A speed control system for an agricultural system having an agricultural vehicle includes a control system. The control system instructs an engine to maintain a constant speed, determines a first estimated speed of the agricultural vehicle associated with increasing a gear index of a step ratio transmission, determines a second estimated speed of the agricultural vehicle associated with decreasing the gear index of the step ratio transmission, instructs the step ratio transmission to increase the gear index if the first estimated speed is closer to a target speed than the second estimated speed and a current speed of the agricultural vehicle, and instructs the step ratio transmission to decrease the gear index if the second estimated speed is closer to the target speed than the first estimated speed and the current speed.

Speed control system for an agricultural vehicle

A continuously variable transmission can have one or more rotatable output shafts, rotatable non-output shafts, continuously variable transmission elements selectively interconnecting at least one non-output shaft and one output shaft so as to permit variation of a transmission ratio therebetween. The transmission can also have one or more control elements for controlling the instantaneously prevailing ratio of the transmission including a sensor device for sensing the rotational position of a non-output shaft, and a processing device for determining the rotational position of the sensed, non-output shaft at a chosen instant. The processing device is connected to control elements to cause variation of the transmission ratio so that the output shaft attains a desired rotational position at a chosen instant.
