In one embodiment, a system for determining maximum available engine output torque includes an engine speed sensor and a control computer produce a fueling command for fueling an internal combustion engine. The computer is configured to produce a maximum available engine output torque value as a function of the engine speed signal and the fueling command. In an alternate embodiment, the system includes a control computer configured to produce the maximum available engine output torque value as a function of engine speed, at least one engine intake parameter associated an intake manifold coupled to the engine, and an engine exhaust parameter associated with an exhaust gas structure coupled to the engine. In either case, an application control strategy is responsive to the maximum available engine torque value to control an engine-driven accessory as a function thereof.
