Automotive engine control system capable of detecting specific engine operating conditions and projecting subsequent engine operating patterns

摘要

An engine control system monitors engine operation by periodically sampling engine operating parameters and records variation patterns of the engine operating parameters as engine operation pattern data whenever any of a number of preselected specific engine operating conditions occur, such as engine stalling, acceleration, or deceleration. The control system normally controls the engine according to conventional engine control procedures and adjusts the control procedures in response to preselected engine operating conditions in accordance with a projected engine operation pattern derived from prerecorded engine operation pattern data and the detected specific engine operating condition. The engine operation pattern data may be repeatedly updated and/or accumulated during engine operation and may be held in a memory of the control system even after the engine is turned off. The engine operating parameters may include the operation state of one or more vehicle components influencing engine operation, such as an air conditioner with a compressor driver by the engine and so acting as an additional load on the engine, or a transmission, the gear position of which can change engine operation significantly.
