ENGINE CONTROL METHOD USED TOGETHER WITH AUTOMATIC CLUTCH CONTROL

摘要

PURPOSE: To harmonize engine speed with a clutch coupling while taking the operating condition of a clutch into account. CONSTITUTION: A friction clutch 20 coupling an engine 10 and a gear transmission 30 of a vehicle is controlled by a microprocessor-based circuit using logic defining operating modes according to the conditions of the engine 10 and the clutch 20. A control signal is generated as a function of a pedal 11 position under control of throttle logic dependent on clutch operating modes defined by the clutch logic. During clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal 11, thereby avoiding engine overspeeding which results from generating high torque before sufficient clutch capacity has been achieved.
