Vorrichtung und Verfahren zur Detektion eines Kraftfahrzeugüberschlags mit einem Drehgeschwindigkeitsschwellwertspegel |
摘要 |
A vehicle rollover event detector (10) includes an accelerometer (80) that senses vehicle acceleration in a direction offset from a front-to-rear axis of the vehicle (12) and provides an acceleration signal (101) indicative thereof. A rollover sensor (14) senses vehicle roll and provides a roll signal (32) indicative of vehicle roll about the front-to-rear axis of the vehicle. A controller (26) compares the roll signal (32) against a first rollover threshold (42) when the acceleration signal (101) is less than an acceleration threshold (113) and compares the roll signal (32) against a second rollover threshold (116) when the acceleration signal (101) is equal to or greater than the acceleration threshold (113) and for indicating a vehicle rollover condition when the roll signal is greater than the threshold (42, 116) it is compared against. <IMAGE> |
