Abstract
In an apparatus for controlling an internal combustion engine for a vehicle provided with an electronically controlled automatic transmission system including a friction-type clutch and a gear-type transmission, the speed of the engine is controlled in accordance with a target speed determined by whether the clutch is engaged or not, and at the moment the clutch becomes engaged, the target engine speed gradually changes from the target speed for the disengaged condition of the clutch to that for the fully engaged condition of the clutch, whereby the mechanical shock occurring at the time of the engagement of the clutch is remarkably reduced.
