ABSTRACT:
An on-vehicle electronic device control system includes a base-device-layer on which base-inputting-devices and base-driven-devices are disposed and plural control layers on which plural control units are disposed. Each of the control units has a lower-to-higher-layer-data-input-portion for inputting data from a lower layer and a higher-to-lower-layer-data-output-portion for outputting control-command-data to a lower layer. At least one of the control units disposed on one of the control layers has a higher-to-lower-data-input-portion for inputting data from a higher layer. At least one of the control units disposed on one of the control layers has a lower-to-higher-data output-portion for outputting data to a higher layer and one of the control units that has the higher-to-lower-data-input-portion functions as a coordinative-control-command-unit that determines output data based on both data inputted thereto from a higher layer and input data from a lower layer and also functions as an autonomous-control-command-unit that determines the output data based only on the input data from the lower layer if the input data from the higher layer are stopped.
