Patent ID: 8340860

Claim:
An acceleration detection device for detecting acceleration of a vehicle, comprising: a stopped acceleration detector that detects a detected stationary acceleration value when the vehicle is stopped on a sloping road based on an acceleration sensor signal from an acceleration sensor mounted on the vehicle; an acceleration change detector that detects an acceleration change associated with the vehicle transitioning from a stationary state to a driving state on the sloping road based on the acceleration sensor signal, the acceleration change detector detecting the acceleration change as a maximum difference between the detected stationary acceleration value and an acceleration value that is detected while the vehicle is rolling back on the sloping road; an acceleration estimating unit that includes an estimated acceleration calculating map in which estimated values of acceleration that correspond to the acceleration change are preset in accordance with vehicle characteristics, the acceleration estimating unit calculating an estimated stationary acceleration value based on the acceleration change that was detected by the acceleration change detector according to the estimated acceleration calculating map; and a correcting unit that corrects the detected stationary acceleration value based on a deviation between the estimated stationary acceleration value and the detected stationary acceleration value.
