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 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 control of an internal combustion engine having a fueling system that in one mode of operation is under control of an accelerator position sensor free of influence from certain other external sources and in another mode of operation is influenced by one or more of those external sources, the method comprising:
-
when the engine is operating in the one mode, processing data according to an all-speed governing strategy to set desired engine fueling; and
when the engine is operating in another mode, processing data according a strategy other than the all-speed governing strategy to set desired engine fueling. - View Dependent Claims (44, 45, 46)
