A safety logic unit for vehicle rollover detection systems and a method for determining near rollover situations

摘要

The present invention relates to a safety logic unit (1) for vehicle rollover detection systems comprising a main rollover detection logic unit (2) and at least one protection device for the occupant or occupants of a vehicle and a method of determining near rollover situations. The safety logic unit (1) is connected with the vehicle lateral acceleration sensor (11) and generates the output signal appointing situation near rollover event when the lateral acceleration of a vehicle exceeds the first predefined threshold value (15) or, when the lateral acceleration of a vehicle exceeds the second predefined threshold value (16) that is lower than the first predefined threshold value (15) and if at the same time at least one of the additional activation signals of the safety logic unit (1) is present. An additional activation signal of the safety logic unit (1) is preferably delivered by the main logic unit (2) at an intermediate stage of path of processing of the signal.
