Machine's i.e. off-highway truck, ground speed limiting method for e.g. shipping facility, involves propelling machine at speed, and limiting speed in response to engine control message by executing engine control algorithm

摘要

The method involves propelling a machine at a speed by transmitting an engine power to a ground engaging member of the machine, and executing a vehicle speed limit algorithm in an electronic transmission controller (28) to determine an engine control message. The message is communicated to an electronic engine controller. The speed is limited responsive to the message by executing an engine control algorithm. The message is contained in a speed limit data field of a torque/speed control message of a society of automotive engineers (SAE) J1939data bus communication. Independent claims are also included for the following: (1) a transmission comprising a housing (2) a machine comprising a chassis.
