    • PURPOSE: To detect slip condition of a road surface at an early time in the beginning stage of steering before a vehicle reaches a spinning state, by estimating the slip condition between wheels and road surface by the use of a sensor of general use without needing a special sensor such as a sensor for use in detecting steering reactive force. CONSTITUTION: A circuit 39 which computes every moment a residual between a fiducial condition quantity estimated and a detected condition quantity detected and accumulates time-sequential data of fiducial residuals in accordance with a difference between slip condition of a travelling road surface and that of a fiducial road surface. Circuits 42, 43 which accumulate time-sequential data of residual models in accordance with differences between slip condition of other road surfaces having pre-determined slip and that of the fiducial road surface. The slip condition of the travelling road surface is estimated by finding which of the other road surfaces having pre-determined slip is approximate to the travelling road surface by comparing a time sequence pattern of the time-sequential data of fiducial residuals with that of the time-sequential data of residual models.
