Abstract: According to one aspect of the present invention, a control apparatus for an in-vehicle apparatus includes a first sensor and a second sensor configured to output sensor data, and a first microprocessor and a second microprocessor. A second sensor data request signal generation portion of the second microprocessor is configured to generate a second sensor data request signal. The first microprocessor includes a first sensor data request signal generation portion, a first data comparison portion, a first abnormality determination portion, and a first instruction signal generation portion. The first sensor data request signal generation portion is configured to generate a first sensor data request signal. The first data comparison portion is configured to compare first comparison data selected from a plurality of an first sensor data and second comparison data selected from a plurality of an second sensor data. The first abnormality determination portion is configured to determine whether an abnormality has occurred in an sensor portion based on a result of the comparison by the first data comparison portion.

Abstract: A motor actuator of the present invention includes, between a battery and an inverter, a first solid state relay and a second solid state relay in which directions of parasitic diodes are opposite to each other. When supply of power from the battery to the inverter is to be interrupted, the first solid state relay is brought into an OFF state or all of a plurality of field effect transistors are brought into the OFF state, and then the second solid state relay is brought into the OFF state.
