Acceleration detection device

摘要

An acceleration detection device is provided with a zero point correction unit for correcting a zero point position of a sensor signal by a correction amount based on the acceleration signals when the neutral control starts and ends, respectively, and an acceleration signal Gsen-r that is eliminated of a body vibration from an acceleration signal Gsen-f after passing a filter at transition from a vehicle stationary state to the running state.

主权项

1. An acceleration detection device, comprising:
a vibration component elimination unit that eliminates a vehicle body vibration component included in an acceleration sensor signal, the vehicle body vibration component generated when a brake is released to transition from a vehicle stationary state to a running state, the vibration component elimination unit configured to eliminate the vehicle body vibration component by applying an averaging process on a plurality of acceleration signals obtained at transition from the vehicle stationary state to the running state; and a zero point correction unit that corrects with a correction value a zero point position of the acceleration sensor signal after the vehicle body vibration component is eliminated from the acceleration sensor signal.
