CIRCUIT ARRANGEMENT FOR MEASURING THE DECELERATION OF A VEHICLE, CAUSED BY A PRE-CRASH BRAKING PROCEDURE

摘要

The invention relates to a circuit arrangement which can be configured using simple circuit elements for measuring the deceleration of a vehicle which is caused by a braking procedure prior to a crash and which leads to a change in the sitting position of the vehicle occupants. The deceleration is measured by an acceleration sensor (BS) which is designed to detect the increased deceleration which occurs prior to a crash. An amplifier (OP) is provided which amplifies the output voltage (UO) of the sensor (BS) resulting from low deceleration, in such a way that the digital measuring signal (MS) which is derived from the amplified output voltage (UOV) by an analog-digital converter (AD) provides a sufficiently high resolution of the deceleration.
