置。[Scope of Claim for Utility Model Registration] An engine control unit that controls the operation of a vehicle engine, an automatic transmission control unit that controls the transmission operation of a transmission connected to the engine output shaft,
are provided independently so that they can communicate with each other,
In a control device for a vehicle engine and automatic transmission, in which the engine control unit is configured to control the engine based on an engine control request signal output from the automatic transmission control unit to the engine control unit, the engine control request signal is automatically transmitted. an operating condition storage means for storing operating conditions when output from the transmission control unit; a communication line abnormality determination means for determining an abnormality in a communication line between the engine control unit and the automatic transmission control unit; and an abnormality in the communication line. Fail-safe means for outputting an engine control request signal based on the operating conditions stored in the operating condition storage means instead of the engine control request signal from the automatic transmission control unit when the determining means determines that there is an abnormality in the communication line. and,
1. A control device for a vehicle engine and automatic transmission, characterized in that: is provided on the engine control unit side.
