Abstract:
A machine is disclosed. The machine may include a continuously variable transmission, a location or movement module, and a controller. The controller may receive a first signal indicating a transmission output speed for the machine. The controller may receive, from the location or movement module, a second signal indicating location or movement information of the machine. The controller may determine a traction value based on the first signal and the second signal. The controller may determine a rimpull limit value based on the traction value. The controller may provide the rimpull limit value to the continuously variable transmission, wherein the continuously variable transmission is to determine a transmission output torque of the machine based on the rimpull limit value.
