Arrangement for triggering a vehicle safety device
First Claim
1. An arrangement for triggering a safety device for a vehicle, the arrangement comprising a proximity sensor configured to provide a proximity signal related to at least one of the distance to an object and the relative velocity between the object and the proximity sensor, an accelerometer, a first processing unit to perform a crash algorithm on the proximity signal received from the proximity sensor and an acceleration signal received from the accelerometer and generating a first signal, and a second processing unit to perform an arming algorithm on the proximity signal and the acceleration signal and generating a second signal, the arrangement generating a trigger signal in response to simultaneous output of the first signal from the first processing unit and the second signal from the second processing unit.

Abstract
An arrangement for triggering a motor vehicle safety device. The arrangement incorporates a proximity sensor (1) which is configured to provide a proximity signal related to the distance to an object and/or the relative speed between the object and the sensor (1). The arrangement also includes an accelerometer (2) and a first processing unit (3) which is configured to perform an arming algorithm on signals received from the proximity sensor (1) and the accelerometer (2). A second processing unit (6) is provided to perform a crash algorithm on signals received from the proximity sensor (1) and the accelerometer (2). The arrangement incorporates a logic gate (4) to generate a triggering signal (5) in response to simultaneous output of signals from the first processing unit (3) and the second processing unit (6).
