Abstract
A device for calibrating a neutral point of a longitudinal acceleration sensor of a vehicle, having a detector for detecting that the vehicle is running at a speed higher than a predetermined threshold speed, a detector for detecting that the vehicle is not braked beyond a predetermined threshold braking, a detector for detecting that the vehicle is not driven beyond a predetermined threshold traction, and a detector for detecting output of the longitudinal acceleration sensor to provide a deflection of its neutral point when the running detector is detecting that the vehicle is running at a speed higher than the predetermined threshold speed, the braking detector is detecting that the vehicle is not braked beyond the predetermined threshold braking, and the traction detector is detecting that the vehicle is not driven beyond the predetermined traction, respectively.
