Zusammenfassung:	A driver assistance apparatus and method for a driver assistance apparatus for verifying the safe operation of the apparatus. It is important to verify that operating instructions that dictate the operation of a driver assistance system are verified. The apparatus includes a safety electronic control unit ("ECU") and the safety ECU includes operating instructions stored thereon that dictate the operation of the safety ECU. The safety ECU further includes a verified hash storage means for storing a verified hash value of at least a portion of the operating instructions. The safety ECU is configured to implement a verification routine, which includes calculating, using a hash function, a test hash value of the at least a portion of the operating instructions; comparing the test hash value with the verified hash value, and if the test hash value is not equal to the verified hash value, performing a safety routine.
