Torque speed control authority for an engine having an all-speed governor
First Claim
1. Apparatus comprising:
- an internal combustion engine having a fueling system for fueling the engine;
one or more sources providing data relevant to operations of one or more systems of the apparatus that are external to the engine but potentially influential on fueling of the engine; and
an engine control system comprising a processor for processing data according to an all-speed governing strategy for controlling the fueling system to develop all-speed governed fueling data that sets engine fueling when a data input to the engine control system from the one or more sources discloses no need to influence engine fueling, but when the data input from such one or more sources discloses a need to influence engine fueling, that data input causes engine fueling to be set by a strategy other than the all-speed governing strategy.

Abstract
A motor vehicle (20) has a diesel engine (22) and one or more sources (30, 36) providing data relevant to operations of the vehicle that are external to the engine but potentially influential on fueling of the engine. An engine control system (24) processes data according to an all-speed governing strategy for controlling engine fueling to develop all-speed governed fueling data (MFGOV) that sets engine fueling when a data input to the engine control system from the one or more sources discloses no need to influence engine fueling. When the data input from such one or more sources discloses a need to influence engine fueling, that data input causes engine fueling to be set by a strategy other than the all-speed governing strategy, a torque speed control strategy (54) in particular.

43. A method for governing an internal combustion engine that forms one portion of an apparatus having one or more systems external to the engine and that has an engine control system that includes an accelerator position sensor, the engine having a fueling system that is under control of the engine control system, the method comprising:
-
governing the engine by processing data in the engine control system, including accelerator position sensor data, according to an all-speed governing strategy to set desired engine fueling free of influence by the one or more systems external to the engine; governing the engine by processing data, including accelerator position sensor data, according a governing strategy other than the all-speed governing strategy to set desired engine fueling when the one or more systems external to the engine operate in a manner calling for interrupting the all-speed governing strategy. - View Dependent Claims (44, 45, 46)
