摘要:
A system for electronically controlling an engine for a vehicle is disclosed which is of the kind electrically controlling the opening of a throttle valve controlling the quantity of intake air supplied to the engine. The electronic engine control includes setting a target acceleration of the vehicle according to an amount of depression of an accelerator pedal by the driver, comparing the target acceleration with an actual acceleration of the vehicle to find an error therebetween, setting a target value of the throttle valve opening on the basis of the acceleration error, and controlling the throttle valve opening until it attains the target value.
摘要:
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.
