A vehicular drawing device includes a first operating system, a second operating system, a first circuit block group, a second circuit block group, a first power circuit, a second power circuit, and a controller circuit. The first circuit block group is used in the first operating system. The second circuit block group is used in the second operating system. The first power circuit is configured to supply a sub power to the first circuit block group. The second power circuit is provided separately from the first power circuit, and the second power circuit is configured to supply a main power to the second circuit block group. In response to the main power being abnormal, the controller circuit is configured to (i) maintain supplying of the sub power from the first power circuit to the first circuit block group and (ii) terminate an operation of the second power circuit.
