Abstract
In a system for integrally controlling an automatic transmission and an engine, an apparatus for controlling the automatic transmission and an apparatus for controlling the engine are formed separately from each other to reduce size and cost, and to facilitate the mounting of control means onto a vehicle. Further, if trouble occurs in this communication system between the engine control apparatus and the automatic transmission control apparatus countermeasures are properly performed, and a trouble is reduced as much as possible.
