PURPOSE:To speedily prevent the slip of a driving wheel which is generated on start or in acceleration of a car by controlling the output of an internal-combustion engine by opening and closing a throttle valve at the speed corresponding to the slip state of a driving wheel. CONSTITUTION:During the traveling of a car, the driving-wheel speed VW and the trailing-wheel speed VV are detected by a driving-wheel speed detecting means (b) and a trailing-wheel speed detecting means (d) which are installed with respect to a driving wheel (a) and a trailing wheel (c). A standard speed VT is calculated by a standard-speed calculating means (e) on the basis of the detected trailing-wheel speed VV, and said standard speed VT is compared with the driving-wheel speed VW in a slip judging means (g), and the slip state of the driving wheel (a) is judged. In other words, when VW>VT, the slip generation is judged, and when slip is judged, a throttle driving means (i) is controlled on the basis of the result of calculation of a correction-speed calculating means (f) and a standard-speed calculating means (e), and the output of an internal-combustion engine (h) is varied.
