A vehicular control apparatus that functions more reliably is provided. A quasi-abnormality control circuit (65) brings one of a clock signal (A), an internal watchdog signal (B), and an answer signal (Ca) into a quasi-abnormal state when an ignition is switched on. A clock determining circuit (61), an internal watchdog signal determining circuit (62), and a Q&A watchdog circuit (63) output determination signals (DS)1 - DS3), respectively. One of the determination signals (DS1 - DS3) corresponds to a monitoring target signal brought into the quasi-abnormal state and indicates an abnormality. A reset signal determining circuit (64) receives the determination signals (DS1 - DS3), and generates a reset signal (R) in accordance with determination results in the determination signals (DS1 - DS3). A quasi-abnormality control circuit 65 switches the monitoring target signal to be brought into the quasi-abnormal state each time the ignition is switched on. |
