An adaptive control system for categorized engine conditions is disclosed in which the engine conditions to be controlled are discriminated and classified in accordance with the driver\s intent and the vehicle operating conditions. It is decided that a given engine control condition is continued or the transition is under way between different control conditions as a history judgement, and a vehicle operation parameter is determined in accordance with the determined history. At the same time, in accordance with the control condition decided and classified, an operating signal is applied to the engine with an operating parameter thus determined and the result of engine control response is observed to update the adaptive parameter.

An adaptive control system for controlling an engine of a vehicle in a plurality of categorized conditions, comprising: a plurality of driving operation sensors for detecting a driving operation of the vehicle taken according to a driver\s intent; a plurality of operating condition sensors including a linear oxygen sensor for detecting operating conditions of the vehicle and the engine; a plurality of actuators for controlling means for operating the engine; condition discrimination means for determining one of engine control conditions from the detected results of the driving operation sensors and the operating condition sensors; a history file for storing past engine control conditions; history judgment means for judging whether the engine control condition at present is in a continuation of same engine control condition or in a transition process between different engine control conditions by comparing a past engine control condition retrieved from the history file with the engine control condition determined by the condition discrimination means; control parameter determining means for determining engine control parameters from the result of judgment of the history judgment means and from an adaptive parameter retrieved from the history file updating means by use of a weighting process corresponding to a degree of transition between control conditions when the history judgment means judges that the engine is in said transition process between different ones of said plurality of engine control conditions, wherein the degree of transition between said different ones of said plurality of engine control conditions is determined from the ratio between a predetermined number of engine detonations needed for a smooth transition between said different ones of said plurality of engine control conditions and a number of engine detonations that has occurred from a first detonation at the start of said transition process; control means having a plurality of control modes corresponding to said control conditions for applying an operating signal to each of the plurality of actuators on the basis of the control parameters determined by the control parameter determining means in each control mode in accordance with the engine control condition discriminated by the condition discrimination means; and adaptive parameter updating means for receiving a control response parameter from the output of the operating condition sensors and for calculating an updated value of the adaptive parameter and for storing the updated value of said adaptive parameter in the history file.
