Control device's component for person protection unit, has interface provided for accident sensor system, and inertial sensor system including acceleration sensor system and rotation rate sensor system

摘要

The component (B) has a semiconductor substrate, and a watchdog for a processor (mu C) provided outside of a chip housing. An evaluation unit evaluates a sensor signal parallel to the processor for opening an ignition circuit switch. A voltage supply supplies voltages for a control device for controlling a person protection unit (PS). An interface is provided for an accident sensor system. An inertial sensor system has an acceleration sensor system and a rotation rate sensor system.
