Occupant protection control system and method of controlling the occupant protection control system
First Claim
1. An occupant protection control system, comprising:
- at least two occupant protection control devices for controlling at least two occupant protection devices disposed in a vehicle, one of said at least two occupant protection control devices having a control unit, a non-volatile memory for permanent storage of accident-related signals in an event of an accident, and a volatile memory, said volatile memory storing data sensed and supplied by the other of said at least two occupant control devices, in the event of the accident, said control unit initiates and controls a re-storage of the data stored in said volatile memory into said non-volatile memory.

Abstract
An occupant protection control system has two occupant protection control devices, in particular a front airbag control device and a side airbag control device. One occupant protection control device contains in addition to a non-volatile memory a further memory, in which the sensor data of the other occupant protection control system, emitted by the other occupant protection control device and monitored for the sensing of a possible accident, are continuously recorded. When an accident is sensed, the data are re-stored from the further memory into the non-volatile memory, in which the accident-relevant data sensed by the other occupant protection control device are also permanently stored.

3. A method of controlling an occupant protection control system having at least two occupant protection control devices, which comprises:
-
storing accident-relevant data of a first control device in a non-volatile memory of the first control device in an event of an accident;
storing continuously data of a second control device in a volatile memory of the first control device; and
re-storing the data of the second control device stored in the volatile memory into the non-volatile memory when the accident is sensed as further accident-relevant data.
