Abstract
With the method of the present invention, a detected value in the longitudinal acceleration-deceleration detector can be corrected for a gradient of a slope acting on the detector when the vehicle is traveling on a sloped road surface. Assuming that a vehicle is traveling on an upward slope or a downward slope, a value in a vertical acceleration-deceleration detector is detected. A determination is made as to whether the vehicle is traveling on the upward or downward slope using a corrected value which is closest to a pseudo-acceleration or deceleration based on wheel speeds. This enables a more accurate estimation of the longitudinal acceleration or deceleration by using the corrected value which is closest to the pseudo-acceleration or deceleration.
