Abstract
An electronic control apparatus for an engine of a vehicle has a first CPU for fuel control which controls the amount of fuel to be supplied to the engine and a second CPU for throttle valve control which outputs a driving signal to an actuator which operates to open or close the throttle valve disposed in an intake pipe to the engine. The apparatus has an opening degree computing member which is provided in the first CPU to compute an opening degree of the throttle valve based at least on an amount of depression of an accelerator and then to output a result thereof as an opening degree signal. The first CPU and the second CPU are connected together by a communication line which transfers the opening degree signal from the opening degree computing member from the first CPU to the second CPU.
