Abstract
A method of limiting machine speed of a dual powertrain machine includes propelling the dual powertrain machine by transmitting power from a first engine of a first electronically controlled powertrain to a first set of ground engaging elements, and transmitting power from a second engine of a second electronically controlled powertrain to a second set of ground engaging elements. The method also includes identifying a machine speed limit, executing a first machine speed limiting algorithm in a first controller of the first electronically controlled powertrain to determine a first engine control command based on the machine speed limit, and controlling the first engine using the first engine control command. A second machine speed limiting algorithm is executed in a second controller of the second electronically controlled powertrain to determine a second engine control command based on the machine speed limit, and the second engine is controlled using the second engine control command.
