Method for disposal ignition of pyrotechnic actuators in motor vehicle, involves storing encrypted disposal algorithm in control unit, and decryption key is derived from one or multiple disposal operation signals

摘要

The method involves storing an encrypted disposal algorithm in a control unit. A decryption key is derived from the one or multiple disposal operation signals. The disposal algorithm is decrypted based on the received decryption key and is executed. The disposal algorithm is formed from two separate and encrypted algorithm parts that are decoded by using the disposal command decryption code. An independent claim is included for a control device for pyrotechnic actuators in a motor vehicle with a memory unit for storing a disposal algorithm.
