发明名称 Zero-point correction device for a gravity-type accelerometer.
摘要 <p>A zero-point correction device for a gravity-type accelerometer employed in a vehicle having wheels, includes a calculator (6, 7, 8) for calculating an estimated vehicle acceleration Aw based on the wheel speed, and a detector (5) for detecting a gravitationally detected acceleration Am based on said gravity-type accelerometer. A subtractor (13) is provided for subtracting a correction amount Ao obtained in each operation cycle from the gravitationally detected acceleration Am to produce a corrected acceleration Ac which is a corrected version of said gravitationally detected acceleration Am. The correction amount Ao for the present operation cycle is obtained by adding to the correction amount Ao obtained in the previous cycle, a value commensurate with a difference between the estimated vehicle acceleration Aw and the corrected acceleration Ac. &lt;IMAGE&gt;</p>
