Abstract

In a system for integrally controlling an automatic transmission and an engine comprising: a member for controlling the engine; a member formed separately of the engine control member, for controlling the automatic transmission; and various communication lines for connecting the engine control member and the automatic transmission control member to each other; judgments are made quickly and without fail as to whether trouble exists, such as disconnections or short-circuits of the various communication lines. When a trouble is detected, the proper control is maintained as much as possible in accordance with the types of trouble.
