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.
