METHOD, DEVICE AND CRASH SENSOR FOR ACTIVATING OCCUPANT PROTECTION SYSTEMS IN A MOTOR VEHICLE |
摘要 |
Occupant protection systems in a motor vehicle are activated in the event of a crash that puts the occupants of the vehicle at risk. A processor-based trigger system evaluates signals of crash sensors and actuates the occupant protection systems. Signatures that are produced by impacts on the vehicle body by means of a crash sensor system are detected and preprocessed directly on site of the crash sensor mounting areas. The crash sensor system includes a plurality of similar multifunctional peripheral crash sensors located in various areas of the vehicle body. The preprocessed signatures or variables derived therefrom are evaluated by means of a crash algorithm associated with the trigger system, in terms of kind, intensity, direction and time of the crash signatures and/or occupant risk signatures. Crash-relevant occupant protection systems are triggered at respective times determined in terms of the achievable protective effect of the occupant protection system when occupant risk threshold values are exceeded. |
