Control unit for a motor vehicle occupant safety system, especially an airbag system, has additional AND gates in addition to dual controlling computers to ensure reliable detection and resetting of a faulty computer unit
Control unit for a motor vehicle occupant safety system, e.g. an airbag system has two computer units (R1, R2) and a trigger unit (AE). A number of AND (AND1, AND2) gates are provided with the outputs of at least two of the AND gates connected to pulse counter comparison units (PZVE1, PZVE2) in the computer units so that each computer unit can reset the other computer unit when an inadmissible number of pulses per time unit is detected from the corresponding AND gate The invention also relates to a corresponding method for monitoring the correct operation of a control unit.
