Transmission control system

A method of controlling a transmission (11) associated with a machine includes determining a first target torque of the transmission (11). The first target torque includes a combination of a torque limit associated with a power source (17) of the machine and a virtual retarding torque. The method al...

Summary:A method of controlling a transmission (11) associated with a machine includes determining a first target torque of the transmission (11). The first target torque includes a combination of a torque limit associated with a power source (17) of the machine and a virtual retarding torque. The method also includes directing the transmission (11) to generate a first output corresponding to the first target torque at an interface between the transmission (11) and the power source (17). The first output of the transmission (11) increases a speed of the power source (17) from a first power source speed to a second power source speed and decreases a travel speed of the machine from a first travel speed to a second travel speed. The method further includes determining that the first target torque is not equal to the torque limit, and determining a second target torque of the transmission (11) in response to determining that the first target torque is not equal to the torque limit. The second target torque is less than the first target torque.
