Abstract:
1. An in-vehicle electronic control apparatus, having a monitoring control circuit, comprising: a main control circuit unit including: a monitoring control circuit unit including: wherein the main control circuit unit is connected to an external control apparatus through a second communication circuit, wherein the main control circuit unit receives control signals from the external control apparatus and transmits the control signals to the external control apparatus, wherein the external control apparatus is provided with collaborating supplementary apparatuses including: wherein, the question information generation unit generates concurrent question information items that are applied to the main control circuit unit and all the external control apparatuses or discrete question information items that are discretely applied to the main control circuit unit and the external control apparatuses; wherein the concurrent question information or the discrete question information items are transmitted from the monitoring control circuit unit to the main control circuit unit and transmitted from the monitoring control circuit unit to the external control apparatuses via the main control circuit unit, wherein the nonvolatile program memory includes a control program which constitutes a main-machine answer generation unit that generates main-machine answer information in accordance with the concurrent question information or the discrete question information items and a control program corresponding to a transmission answer edition unit, wherein the transmission answer edition unit edits the main machine answer information and the supplementary-apparatus answer information and transmits, as answer information, synthesis correct-solution information, the main-machine answer information, or the supplementary-apparatus answer information corresponding to the synthesis correct-solution information, the main-machine answer information, or the supplementary-apparatus answer information included in the monitoring control circuit unit to the monitoring control circuit unit, wherein, in the correct-solution information storage memory, there is stored main-machine correct-solution information items with regard to main-machine answer information generated by the main control circuit unit and/or synthesis correct-solution information obtained by combining and tallying the main-machine correct-solution information and the supplementary-apparatus correct-solution information items for the supplementary-apparatus answer information items, wherein the supplementary-apparatus correct-solution information items are stored in the correct-solution information storage memory or in the nonvolatile program memory, wherein the abnormality determination unit monitors an abnormality in the main control circuit unit, based at least on concurrent question information items generated by the monitoring control circuit unit or discrete question information items, and wherein the main control circuit unit and the monitoring control circuit unit collaborate with each other so as to monitor and discriminate an abnormality in the external control apparatus.
