PROBLEM TO BE SOLVED: To offer an automobile controller which can detect abnormality in simple constitution. SOLUTION: The automobile controller 100 is equipped with an ECU10, a PCU20, a signal line 30, and a communication line 40. An AND circuit 23 computes the AND of a power drive result signal DRVB which shows the drive result of a power source 21, and a CPU drive result signal DRVCP which shows the drive result of a CPU22 or an IPM50, and transmits the operation result to an ECU 10 via the signal line 30 as a drive result signal DRV. The CPU22 transmits normality/abnormality information INF, which shows the normality/abnormality of the CPU22 or the IPM50, to the ECU10 via a communication line 40. The ECU10 judges the normality/abnormality of a power source 21, the CPU22, the IPM50, the signal line 30, and the communication line 40, based on the drive result signal DRV from the signal line 30 and the normality/abnormality information INF from the communication line 40.
