Abstract
An in-vehicle electronic control apparatus, having a monitoring control circuit, according to the present invention is configured in such a way that serial interface circuitsandare connected between a main control circuit unitA and a monitoring control circuit unitA, high-speed full-duplex block communication is performed by use of a communication permission signal ALT and a communication synchronization signal CLK, the same question information included in uplink communication information UPD is recurrently transmitted in a plurality times of communication and updated after being transmitted a predetermined times, and the main control circuit unitA returns answer information by use of downlink communication information DND, within a predetermined duration after the update of the question information; because the question update period is prolonged, the control load on the main control circuit unitA is reduced.
