<p>PURPOSE:To reduce the number of wiring in a vehicle without lowering control accuracy in the case of controlling an engine which is to drive an actuator at a predetermined timing such ignition timing control, fuel injection timing control, etc., as synchronizing with rotation of an internal combustion engine. CONSTITUTION:The number of wiring in a vehicle is reduced by connecting controllers 2-8, driving devices 12-28 and an I/O processing device 30 to each other by means of a communication wire 10. Only detection signals from a crank angle sensor are directly inputted into the power train controller 2, the injector driving device 12 and the I/O processing device 30 through an exclusive signal line 20 after waveform is shaped by an ignition coil driving device 14. And the controllers are built up in such a way that current-carrying start and current breake timings for the injector and the ignition coil are controlled based on the inputted detection signals and a control command value from the power train control device 2, in the injector driving device 12 and the ignition coil driving device 14.</p> |
