    摘要: An engine control system includes an air control module, a spark control module, a torque control module, a transient detection module, and a launch torque module. The air control module controls a throttle valve of an engine based on a commanded predicted torque. The spark control module controls spark advance of the engine based on a commanded immediate torque. The torque control module increases the commanded predicted torque when a catalyst light-off (CLO) mode is active, and increases the commanded immediate torque when a driver actuates an accelerator input. The transient detection module generates a lean transient signal when an air per cylinder increase is detected while the CLO mode is active. The launch torque module generates a torque offset signal based on the lean transient signal. The torque control module increases the commanded immediate torque based on the torque offset signal.

    摘要: An idle speed control motor under computer control positions a throttle stop for setting minimum throttle angles. The motor response to actuating pulses varies from motor to motor so that a gain factor is determined for each motor and is used to calculate the required pulse width to attain a desired throttle displacement. A gain learn program in the engine control computer runs when the ignition is turned off and is effective to extend the motor with a number of pulses of known width, measure the throttle displacement, and determine the gain factor by dividing a standard displacement by the measured displacement. The same program is applied to learning the gain of a throttle motor in an electronic throttle control system.
