Abstract: An electronic control unit includes a computer that outputs a monitoring signal and an external monitoring circuit that monitors a state of the computer based on the monitoring signal. The computer includes a monitoring signal output section that generates and outputs the monitoring signal to the external monitoring circuit by performing a software process; a self-diagnostic section that self-diagnoses the computer and detects an abnormality by identifying a cause of the abnormality; and a break signal output section that outputs a break signal to interrupt an input of the monitoring signal to the external monitoring circuit by performing a hardware process when an abnormality in the monitoring signal output section is detected.

Abstract: An electronic control device includes: a thermoelectric element module that has a plurality of thermoelectric element groups, which are connected in parallel; and a control circuit that supplies a driving power to the thermoelectric element module to perform an operation control of the thermoelectric element module. Additionally, the plurality of thermoelectric element groups respectively have a plurality of thermoelectric elements, which are connected in series. Moreover, each of the plurality of thermoelectric elements is provided with a pair of a p-type semiconductor and an n-type semiconductor. Furthermore, the plurality of thermoelectric element groups have different number of the thermoelectric elements.
