An apparatus for controlling an internal combustion engine provided with a permanent magnet-type starting motor is described comprising: a magnet switch having a switch contact connected between a power source and the starting motor and coil means including series and shunt coils for actuating the contact, a first electric circuit for supplying an electric current from the power source to the starting motor through a key switch and the series coil, a second electric circuit connecting a junction between the key switch and the series coil to the shunt coil for supplying an electric current from the power source through the key switch to the shunt coil, and start controlling means for controlling a given operation of the engine when the starting motor is actuated to rotate for starting the engine. There are comparator means for comparing a voltage at the junction with a predetermined reference voltage thereby determining whether the starting motor is in a predetermined operating condition or not, and means for actuating the starting controlling means upon detecting that the motor is in the predetermined operating condition.
