Abstract:
A machine includes a drive train with an electronically controlled transmission in communication with an electronic engine controller. The machine ground speed is limited by executing a vehicle speed limit algorithm in the electronic transmission controller. This algorithm generates an engine control message that is communicated to the electronic engine controller. The power output of the engine is reduced responsive to the engine control message. The machine responds by not exceeding a prescribed speed limit programmed into the electronic transmission controller. This vehicle speed limiting strategy is particularly applicable to machines without a vehicle speed limiting algorithm resident in the electronic engine controller.
