ACCELERATION DETECTION DEVICE Russian patent published in 2014 - IPC G01M17/00 

FIELD: transport.

SUBSTANCE: acceleration detection device includes vibration component elimination unit (20) to eliminate vehicle body vibration component contained in acceleration sensor (G) signal (Gsen-f) which has passed through filter (13), in going from stopped state to state of motion, and zero point correction unit (21) to correct position of zero point of G-sensor signal (Gsen-f) passed through filter (13) using correction value (Gd) based on G-sensor signal (Gsen-r) from which vehicle vibration component is removed.

EFFECT: drift error correction accuracy.
