Control system and method for idle speed control torque reserve reduction |
摘要 |
A control system for an engine includes a speed error determination module that periodically determines an engine speed error rate based on a difference between a measured speed and a desired speed of the engine, and a torque reserve module that monitors the engine speed error rate and that selectively adjusts a torque reserve of the engine based on the engine speed error rate. The torque reserve module maintains the torque reserve at a predetermined first torque reserve amount while the engine speed error rate is less than a predetermined first error rate and selectively increases the torque reserve above the first torque reserve amount when the engine speed error rate increases above a predetermined second error rate greater than the first error rate. The torque reserve module decreases the torque reserve when the engine speed error rate decreases below the first error rate. A related method is also provided.
