Abstract
Disclosed is a vehicle data abnormality determination device including a storage unit for pre-storing a 2-byte remainder term which is a result of a CRC arithmetic operation on a target area for arithmetic operations in a predetermined memory area, and an arithmetic operation unit for performing a CRC arithmetic operation while including the 2-byte remainder term in this CRC arithmetic operation. Because when performing the CRC arithmetic operation, the vehicle data abnormality determination device performs the CRC arithmetic operation while including the 2-byte remainder term in this CRC arithmetic operation after performing an arithmetic operation on the target area, the vehicle data abnormality determination device always makes the computed result be zero when the data has not been falsified, and can detect whether or not the data has been falsified easily and properly.
