Abstract
Engine speed is measured at successive moments and the gradient DN.sub.mot of the engine speed is determined based on successively measured engine speeds. Speeds of the driven wheels are measured and used to generate wheel speed signals, which in turn are used to control slippage of the driven wheels. The wheel speed signals are subject to a rise limitation dependent on the gradient DN.sub.mot of the engine speed. In a preferred embodiment the rise limitation is active when the vehicle is in first gear, the gradient DN.sub.mot is positive, VABS (n) is greater than or equal to VASR(n-1) , and VABS(n) is greater than or equal to VASR(n-1)+DN.sub.mot /K, where VABS(n) is a wheel speed signal generated by the ABS at moment n and VASR(n-1) is the wheel speed signal generated by the ASR in the previous moment.
