Control apparatus for in-vehicle apparatus

A control apparatus for an in-vehicle apparatus including an actuator, the control apparatus comprising:

• a sensor portion including a first sensor and a second sensor,
• the first sensor being configured to detect a driving state of a vehicle and output first sensor data,
• the second sensor being configured to detect the driving state of the vehicle that is the same detection target as the first sensor, and output second sensor data;
• and
• a microprocessor portion including a first microprocessor and a second microprocessor,
• the second microprocessor including a second sensor data request signal generation portion,
• the second sensor data request signal generation portion being configured to generate a second sensor data request signal,
• the second sensor data request signal being a data signal including information requesting the second sensor to transmit the second sensor data to the microprocessor portion and transmitted from the second microprocessor to the second sensor and the first microprocessor a plurality of times within a predetermined period,
• the first microprocessor including 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 being configured to generate a first sensor data request signal,
• the first sensor data request signal being a data signal including information requesting the first sensor to transmit the first sensor data to the microprocessor portion and transmitted from the first microprocessor to the first sensor a plurality of times within a predetermined period,
• the first data comparison portion being configured to compare first comparison data selected from a plurality of pieces of the first sensor data transmitted to the microprocessor portion a plurality of times according to the first sensor data request signal, and second comparison data selected from a plurality of pieces of the second sensor data transmitted to the microprocessor portion a plurality of times according to the second sensor data request signal,
• the first abnormality determination portion being configured to determine whether an abnormality has occurred in the sensor portion based on a result of the comparison by the first data comparison portion,
• the first instruction signal generation portion being configured to generate a first instruction signal for driving and controlling the actuator based on the first sensor data.
