摘要： First and second control circuit sections that mutually communicate via a series-parallel converter comprise first and second adder-subtracter respectively. When any receiving error occurs in each control circuit section, a variation value 3 is added to the adder-subtracter on the receiving side. When data is normally received, a variation value 1 is subtracted from the adder-subtradcter. Initial value of the adder-subtracter is set to 9. When a current value exceeds 11, first and second error detection signal is generated to carry out alarm display or initialization, and initialization and restart of the other-side control circuit section.

摘要： An ignition timing control apparatus for an internal combustion engine has an air flow sensor for sensing the air flow rate into the air intake pipe of the engine and producing an electrical output signal in the form of pulses having a frequency which is proportional to the air flow rate, and a crank angle sensor for producing an electrical output pulse each time the crankshaft of the engine is at a prescribed crank angle. A pulse counter counts the number of output pulses from the air flow sensor between consecutive output pulses of the crank angle sensor. A controller controls the current to an ignition coil based on the engine rotational speed and on either the output of the pulse counter, or on the output of a calculating mechanism which calculates the amount of intake air into the cylinders of the engine between consecutive output pulses of the crank angle sensor based on the output of the pulse counter.
