Method for the disposal ignition of pyrotechnic actuators in a motor vehicle and control unit

摘要

Method for the disposal ignition of pyrotechnic actuators in a motor vehicle, in which a disposal algorithm is stored in a control unit and, if at least one disposal operation signal of the disposal algorithm is present, a) the disposal algorithm is stored encrypted in the control unit and b) transmitting a decryption code with the disposal operation signal (s) or deriving from the one or more disposal operation signals c) the decryption algorithm is decrypted based on the received decryption code and then executed, d) characterized in that the disposal algorithm consists of at least two separate, respectively encrypted algorithm parts, both of which are decrypted by means of the decryption code received or derived from the disposal command (s), one of the algorithm part being a hardware firing enable signal and the other part of the algorithm generating at least one or multiple software firing commands generated and a Entsorgungszündung only in the presence of both ..
