Abstract
A method is provided for the generation of wheel acceleration control signals and wheel deceleration control signals for an anti-lock system for wheels of a vehicle. The vehicle is furnished with a digital electronic anti-lock system with at least one microprocessor. The microprocessor calculates a wheel comparison speed (v.sub.diff). The wheel comparison speed is obtained by a filtering of the actual wheel speed (v.sub.wheel), and follows in time to the actual wheel speed (v.sub.wheel). A deceleration signal (-b) or an acceleration signal (+b), respectively, is then furnished when the absolute value of the difference (.DELTA.) between the wheel comparison speed (v.sub.diff) and the actual wheel speed (v.sub.wheel) surpasses a preset value as based on the sign of the difference (.DELTA.).
