摘要

A procedure for controlling a fuel pump for a car has the fuel pump switched off by the engine control apparatus subject to an accident on the basis of a crash signal. A restart function of the fuel pump only takes place when in the engine control apparatus, a speed signal of the IC engine is present. A restart function of the fuel pump also only takes place when in the engine control apparatus, a starter signal is present that shows the operation of the starter motor of the engine. Again, all this occurs when the speed signal of the engine exceeds a certain value.
