Vehicle safety system with safety device controllers

摘要: A vehicle safety system has a plurality of device controllers (200) for controlling devices such as airbag assemblies, seat belt tensioner fuel cutoff switch battery disconnect assemblies sending notification to emergency services, and location data. The accepts data from other systems speed the antilock brake distinguish between low high crash, occupancy selectively activate airbags, steering acceleration detect rollover conditions. provides fault detection operator, well immunity electromagnetic interference through use distributed that communicate with central electronic control unit (300) over digital communication bus (500) using coded commands Each controller capability performing self-tests communicating results unit.
