Abstract
A descending grade condition detecting system which can accurately detect a descending grade such as a snow-packed road or the like where slippage is likely determines whether permission has been granted to perform descending grade determination. If so, it determines whether established vehicle body deceleration is 0.3 G or less. If so, the system determines whether a road surface at each of the wheels is low .mu. corresponding to a snow-packed road or the like. If estimated vehicle body deceleration is small and of comparatively high .mu., descending grade condition flags KF are set for the respective wheels for which determination thereof has been made to indicate that a condition of a road being traveled is a condition of a low .mu. descending grade of a snow-packed road or the like.
