Disclosed is an integrated digital control SYSTEM and method for an
automotive electrical device. The SYSTEM comprises switch means for
controlling each portion of a vehicle, the switch means including
switches; switch monitor means for displaying switch functions and
operational states of the switches input from the switch means; switch
control means for generating pulse signals corresponding to the switches
operated and controling the switch monitor means; auxiliary control means
for performing input/output control, malfunction detection, automatic
control, etc. of each logic-division portion; central control means for
performing control of the auxiliary control means and all data; instrument
panel/monitor means for performing an instrument panel stimulation and
applications program graphic processing according to control by the
central control means; and RPM pulse generating means for providing RPM
pulses to the central control means and the auxiliary control means
through an RPM pulse cable. The method comprises the steps of performing
logic divisions of each portion of the vehicle into predetermined regions;
performing digital conversion of corresponding input/output data according
to each divided region, and analyzing the input data according to region
and performing integrated management into integrated code data to control
the electrical device in the corresponding region; detecting malfunctions
of the electrical device in the corresponding region; and controlling the
detected malfunctions in the corresponding region.
