Abstract
An acceleration detection device for detecting detected acceleration of a vehicle is provided with a stopped acceleration detector, an acceleration change detector, an acceleration estimating unit and a correcting unit. The stopped acceleration detector 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. The acceleration change detector 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 estimating unit estimates an estimated stationary acceleration value based on the acceleration change that was detected by the acceleration change detector. The correcting unit corrects the detected stationary acceleration value based on a deviation between the estimated stationary acceleration value and the detected stationary acceleration value.
