ABSTRACT:
An apparatus for detecting failures of a longitudinal acceleration sensor for detecting a longitudinal acceleration of a motor vehicle, comprising: a wheel speed calculating device for calculating wheel speeds on the basis of outputs of wheel speed sensors; an estimated vehicle body acceleration calculating device for calculating an estimated vehicle body acceleration on the basis of the wheel speeds; a comparative arithmetic device which calculates a ratio of a vehicle body acceleration calculated from an output of the longitudinal acceleration sensor to the estimated vehicle body acceleration and calculates a first integrating value by performing a subtraction and an addition for the first integrating value when the ratio falls within and out of a predetermined range, respectively; and a fail-safe device for performing a predetermined fail-safe processing if the first integrating value is larger than a predetermined value.
