ABSTRACT:
An engine output control apparatus for use with an automotive vehicle supported on a road surface by a pair of driven road wheels and a pair of non-driven road wheels to control an output transmitted from an internal combustion engine to the driven road wheels through an automatic transmission adapted to produce changes up based on engine output and vehicle speed. A traction control signal is produced when the degree of slip of the driven road wheels is equal to or greater than a predetermined value. The engine output is reduced in the presence of the traction control signal. Changes up are produced at higher vehicle speeds in the presence of the traction control signal than in the absence of the traction control signal when the engine output is equal to or less than a predetermined value.
